The Antibiotic-Probiotic Debate: Benefits and Controversies
The use of probiotics alongside antibiotics has been a topic of debate in the medical community. While some studies suggest potential benefits, others raise concerns about their efficacy and long-term effects on gut health.
Potential Benefits of Probiotics with Antibiotics
What does research say about the benefits of taking probiotics with antibiotics? A Cochrane review of 23 studies involving 3,938 participants found that probiotics may help reduce the incidence of antibiotic-associated diarrhea, particularly in children. The review reported:
- 8% of participants in the probiotic group experienced diarrhea compared to 19% in the control group
- A relative risk of 0.46 (95% CI 0.35 to 0.61)
- A number needed to treat (NNT) of 10
Which probiotic strains were found to be most effective? The review suggested that Lactobacillus rhamnosus or Saccharomyces boulardii at 5 to 40 billion colony-forming units per day may be the most appropriate choice for preventing antibiotic-associated diarrhea.
Concerns and Controversies
Why are some researchers cautious about recommending probiotics with antibiotics? A 2019 Italian study raised concerns about the impact of probiotics on gut microbiome recovery after antibiotic use. The study found:
- Participants given probiotics after antibiotics took six months for their gut microbiome to return to its normal state
- Those not given probiotics saw their gut microbiome return to normal in just three weeks
What implications does this study have for probiotic use? These findings suggest that the traditional practice of taking probiotics after antibiotics may not always be beneficial and could potentially delay the natural recovery of the gut microbiome.
Understanding the Gut Microbiome and Its Importance
The gut microbiome plays a crucial role in our overall health and well-being. But what exactly is the gut microbiome?
How is the gut microbiome defined? The gut microbiome refers to the trillions of bacteria, fungi, and viruses that inhabit our digestive tract. This complex ecosystem of microorganisms has a profound impact on various aspects of our health, including:
- Digestion and nutrient absorption
- Immune system function
- Mental health
- Metabolism
Why is maintaining a healthy gut microbiome important? A balanced gut microbiome is essential for:
- Protecting against harmful pathogens
- Producing essential vitamins and short-chain fatty acids
- Regulating inflammation
- Supporting overall well-being
The Impact of Antibiotics on Gut Health
While antibiotics are essential for treating bacterial infections, they can also have unintended consequences on our gut microbiome. Understanding these effects is crucial for maintaining optimal gut health.
Disruption of Microbial Balance
How do antibiotics affect the gut microbiome? Antibiotics work by killing or inhibiting the growth of bacteria, but they often cannot distinguish between harmful and beneficial bacteria. This can lead to:
- A reduction in the diversity of gut microbes
- Overgrowth of opportunistic pathogens
- Alterations in metabolic functions
What are the potential consequences of this disruption? The imbalance caused by antibiotics can result in:
- Increased susceptibility to infections
- Digestive issues such as diarrhea or constipation
- Nutrient deficiencies
- Long-term changes in gut microbiome composition
Recovery of the Gut Microbiome
How long does it take for the gut microbiome to recover after antibiotic use? The recovery time can vary depending on several factors, including:
- The type and duration of antibiotic treatment
- Individual differences in microbiome composition
- Diet and lifestyle factors
What strategies can help support gut microbiome recovery? Some potential approaches include:
- Consuming a diverse, fiber-rich diet
- Incorporating fermented foods into the diet
- Considering probiotic supplementation (under medical guidance)
- Exploring alternative options like autologous fecal transplantation in specific cases
Alternatives to Traditional Probiotics: Emerging Research
As the debate around probiotic use with antibiotics continues, researchers are exploring alternative approaches to support gut health during and after antibiotic treatment.
Fermented Foods
How can fermented foods benefit gut health? Fermented foods are rich in beneficial bacteria and may help support a healthy gut microbiome. Some examples include:
- Sauerkraut
- Kimchi
- Kefir
- Yogurt
- Kombucha
What advantages do fermented foods offer over probiotic supplements? Fermented foods provide a diverse array of microorganisms along with other beneficial compounds, potentially offering a more holistic approach to gut health support.
Autologous Fecal Transplantation
What is autologous fecal transplantation? This emerging technique involves:
- Collecting stool samples from an individual before antibiotic treatment
- Freezing and storing the samples
- Reintroducing the stored fecal material to the gut after antibiotic treatment
What are the potential benefits of autologous fecal transplantation? Studies have shown promising results, including:
- Faster recovery of the gut microbiome (within 8 days) compared to 21 days without intervention
- Restoration of the individual’s unique microbial composition
What limitations does this approach currently have? At present, autologous fecal transplantation is only approved for treating C. difficile colitis, an inflammation of the colon caused by Clostridium difficile bacteria.
Navigating Antibiotic Use: Best Practices for Gut Health
While antibiotics are often necessary for treating bacterial infections, there are steps you can take to minimize their impact on your gut health and support a healthy microbiome.
Responsible Antibiotic Use
How can you ensure responsible antibiotic use? Consider the following guidelines:
- Only take antibiotics when prescribed by a healthcare professional
- Complete the full course of antibiotics as directed
- Avoid using leftover antibiotics or sharing prescriptions with others
- Discuss potential alternatives with your doctor for minor infections
Supporting Gut Health During and After Antibiotic Treatment
What strategies can help maintain gut health while taking antibiotics? Consider implementing the following approaches:
- Consume a diverse, plant-based diet rich in fiber and prebiotic foods
- Stay hydrated to support digestive function
- Incorporate fermented foods into your diet
- Consider probiotic supplementation under medical guidance
- Manage stress through relaxation techniques or exercise
How can you support gut microbiome recovery after completing antibiotic treatment? Focus on:
- Gradually reintroducing a variety of nutrient-dense foods
- Consuming foods rich in polyphenols, such as berries, dark chocolate, and green tea
- Engaging in regular physical activity
- Getting adequate sleep to support overall health and immune function
The Future of Antibiotic and Probiotic Research
As our understanding of the gut microbiome and its interactions with antibiotics and probiotics continues to evolve, researchers are exploring new avenues for supporting gut health and minimizing the negative impacts of antibiotic use.
Personalized Microbiome Interventions
How might future treatments be tailored to individual microbiomes? Emerging research is focusing on:
- Developing personalized probiotic formulations based on an individual’s unique gut microbiome composition
- Identifying specific bacterial strains that may be more resistant to antibiotic-induced disruption
- Creating targeted prebiotics to support the growth of beneficial bacteria during and after antibiotic treatment
Novel Antibiotic Approaches
What innovative strategies are being explored to minimize the impact of antibiotics on gut health? Researchers are investigating:
- Narrow-spectrum antibiotics that target specific pathogens while sparing beneficial bacteria
- Antibiotic-degrading enzymes to limit the impact of antibiotics on the gut microbiome
- Combination therapies that pair antibiotics with protective agents to support gut health
As research in this field continues to advance, it is likely that we will see more targeted and personalized approaches to antibiotic use and gut health support in the coming years.
Conclusion: Balancing Antibiotic Use and Gut Health
The relationship between antibiotics, probiotics, and gut health is complex and continues to be an area of active research. While antibiotics play a crucial role in treating bacterial infections, their impact on the gut microbiome cannot be ignored. The decision to use probiotics alongside antibiotics should be made on a case-by-case basis, considering factors such as the specific antibiotic being used, the individual’s health status, and the potential benefits and risks.
As our understanding of the gut microbiome grows, it is likely that more targeted and personalized approaches to antibiotic use and gut health support will emerge. In the meantime, focusing on a healthy diet, lifestyle, and responsible antibiotic use can help maintain a balanced gut microbiome and support overall health.
Ultimately, the key to navigating antibiotic use and gut health lies in staying informed, working closely with healthcare providers, and remaining open to new research and recommendations as they emerge. By taking a proactive approach to gut health and antibiotic use, we can work towards minimizing the negative impacts of these powerful medications while maximizing their life-saving potential.
Should you take probiotics with antibiotics?
Medically reviewed by Carmen Pope, BPharm. Last updated on Nov 7, 2022.
There is controversy about whether you should routinely take probiotics with antibiotics and the question cannot be answered with a straight yes or no.
Evidence for taking probiotics with antibiotics includes a Cochrane review which reported that children who were given a course of probiotics after antibiotics had less diarrhea. Evidence against taking probiotics with antibiotics includes a 2019 Italian study that reported that the gut microbiome of people given probiotics after antibiotics took six months to return to its normal state compared to only three weeks for those not given any probiotics.
More studies are needed before a definite statement can be made.
What studies support giving probiotics with antibiotics?
A Cochrane review of 23 studies (3938 participants) investigated giving probiotics containing either one or a combination of the following: Bacillus spp. , Bifidobacterium spp., Clostridium butyricum, Lactobacilli spp., Lactococcus spp., Leuconostoc cremoris, Saccharomyces spp., or Streptococcus sp.
Results from 22/23 trials that reported on the incidence of antibiotic-associated diarrhea show a significant benefit from probiotics compared to active, placebo, or no treatment control (8% in the probiotic group compared to 19% in the control group). None of the 16 trials (n = 2455) that reported on side events documented any serious side events attributable to probiotics with the most common ones being rash, nausea, gas, flatulence, abdominal bloating, abdominal pain, vomiting, increased phlegm, chest pain, constipation, taste disturbance, and low appetite. The author’s concluded that there was a protective effect of probiotics for preventing antibiotic-associated diarrhea. The relative risk was 0.46 (95% CI 0.35 to 0.61) and the NNT was 10.
The authors considered Lactobacillus rhamnosus or Saccharomyces boulardii at 5 to 40 billion colony forming units/day to be the most appropriate choice. They also commented that although no serious adverse events were observed among the otherwise healthy children in these trials, serious adverse events have been observed in severely debilitated or immuno-compromised children with underlying risk factors (eg, central venous catheter use), and advised that probiotics should be avoided in pediatric populations at risk for adverse events until further research has been conducted.
What studies do not recommend giving probiotics with antibiotics?
Researchers from the Weizmann Institute of Science in Israel and other institutions reported that the gut microbiome took longer to return to normal in those people given an 11-strain probiotic treatment for four weeks following a course of antibiotics. This was despite the probiotics effectively colonizing the gut with healthy bacteria. The trouble was the presence of the new bacteria and yeasts strains prevented the gut microbiome from returning to normal for the full six month study period.
Conversely, the gut microbiome in those given no probiotics returned to normal within three weeks of going off the antibiotics. “ The authors did conclude that this study just examined one type of probiotic, and a different probiotic may be helpful in patients taking different antibiotics. However, they did point out the findings of the study imply that the traditional practice of taking a probiotic after antibiotic may not be beneficial.
More research is needed to determine if other options to strengthen the gut microbiome, such as fermented food products (eg, sauerkraut and kimchi) or fecal transplantation, is beneficial. Studies have shown that autologous fecal transplantation, which involves collecting stool samples before going on antibiotics and freezing them, brought the gut microbiome back to normal within eight days once the stool was returned to the gut following antibiotic treatment. It took 21 days for the gut microbiota in the group that didn’t undergo fecal transplantation to return to perfect health. Currently, however, the only approved indication for autologous fecal transplantation is for people with C. difficile colitis, which is an inflammation of the colon caused by the bacteria Clostridium difficile.
What are the most common side effects of probiotics?
The most common side effects reported with probiotics in clinical trials included:
- abdominal bloating
- abdominal pain
- chest pain
- constipation
- flatulence
- gas
- increased phlegm
- low appetite
- nausea
- rash
- taste disturbance
- vomiting.
What is the gut microbiome?
Our digestive tract is home to trillions of bacteria as well as fungi and viruses – these are known as the gut microbiome.
The makeup of this biome is largely genetically determined; however, it is heavily influenced by several factors such as whether we are born naturally (vaginally) or by cesarean section, if we were breastfed, our use of antibiotics, and our exposure to chemicals, pesticides, and other toxins.
Scientists now know that this microbiome is critical to our overall well-being. Some call it our second brain. Small imbalances can cause significant changes to our mental health and in the appearance of our skin and has been linked to almost every known condition such as Alzheimer’s disease, multiple sclerosis, rheumatoid arthritis, and Type 2 diabetes.
An imbalance may also cause constipation, diarrhea, skin rashes, yeast infections, and a suppressed immune system. Your likelihood of putting on weight also comes down to your microbiome and the influence it has on your response to insulin and thyroid gland function.
What are probiotics?
Probiotics are live bacteria and yeasts that are beneficial for health. They are often referred to as ‘good’, ‘helpful’, or ‘healthy’ bacteria.
Probiotics are available as dietary supplements and can be brought over the counter from a drug store, pharmacy, or health store. Probiotics are also found naturally or added to foods such as dark chocolate, yogurt, miso soup, pickles, sauerkraut, tempeh, or kefir.
What is the rationale behind taking probiotics with antibiotics?
Taking an antibiotic for an infection can kill beneficial bacteria that live in your gut.
Probiotics may be taken orally to restore any imbalance in the normal intestinal or urogenital flora. This is the rationale behind taking probiotics with antibiotics. Severe antibiotic-induced diarrhea can also lead to an infection with Clostridium difficile, also known as C. difficile, a bacteria which can cause dangerous inflammation in your colon (colitis).
Experts have hypothesized that If you suffer from stomach cramping, gas or diarrhea when you take antibiotics, adding a probiotic may help to lessen, or even prevent, these symptoms. The addition of a probiotic will also reintroduce helpful bacteria into your digestive tract that have been killed or had their numbers reduced by the antibiotic.
How should I take probiotics with antibiotics?
If you do decide to take a probiotic with an antibiotic, start it the same day you start the antibiotic, but do not take it at exactly the same time as the antibiotic. Allow at least two hours to elapse after taking your antibiotic before you take your probiotic.
Probiotics are usually taken twice a day on an empty stomach. They should then be continued for at least several weeks after your course of antibiotics has finished, although some people take probiotics daily to not only continue to help digestion but to boost their immune system and enhance the absorption of some nutrients.
If you wish to take probiotic supplements, choose a high-quality probiotic made by a reputable company that contains at least one of the following: Lactobacillus rhamnosus, Saccharomyces boulardii, or Bifidobacterium sp. at 5 to 40 billion colony units/day.
Do prebiotics help return the gut microbiome to normal?
Prebiotics are foods for probiotics and include fiber-rich foods such as fruits, vegetables, cereals.
Mixing prebiotics with probiotics, such as yogurt with fruit and cereal or sauerkraut with a vegetable stir fry could be helpful for your gut, although there is no scientific evidence to support this.
Good prebiotic foods include vegetables such as artichokes, asparagus, garlic, onions, and any green vegetable; fruits such as bananas, berries, and tomatoes; herbs such as chicory or garlic; grains like barley, oat, and wheat; and other fibers such as inulin that may be available on its own or added to foods such as granola bars, cereal, and yogurt.

What are antibiotics? – article on the website Aptechestvo, Nizhny Novgorod
Antibiotics are a group of drugs that are used in the treatment of bacterial infections. Bacteria are living microorganisms that, having penetrated into the human body, begin active life and reproduction. The effect of antibiotic therapy is the direct destruction of the pathogen, as well as slowing down the reproduction of pathogens. In connection with these antibacterial drugs are divided into 2 large groups: bactericidal – destroying the bacterium itself, as well as bacteriostatic, inhibiting their growth. In addition, antibiotics have a narrow and broad spectrum of action. Narrow-spectrum drugs destroy the infection selectively, while broad-spectrum drugs destroy most of the microorganisms, including those that benefit humans. What antibiotics to take for the treatment of various diseases should be decided by the doctor after the diagnosis. Taking such drugs at your own discretion is fraught with complications.
Fluoroquinolones
They suppress the activity of enzymes involved in the formation of bacterial DNA, as a result of which the infection dies. The drugs are available in the form of tablets, injections, ophthalmic drops. Indications for appointment:
This group of drugs:
Ciprofloxacin;
Ofloxacin;
Pefloxacin;
Norfloxacin.
Aminoglycosides
Broad-spectrum agents that kill most types of Gram-negative aerobic and facultative bacteria. The active substance disrupts the process of protein synthesis, as a result of which the pathogen is destroyed and dies.
Aminoglycosides are poorly absorbed when taken orally, so, as a rule, they are prescribed as intravenous or intramuscular injections. Members of this group:
Amikacin;
Gentamicin;
Kanamycin;
Neomycin;
Plazomycin;
Streptomycin.
As a rule, these drugs are used in combination with other antibiotics to treat such infectious diseases:
Tetracyclines
Bacteriostatic antibiotics that retard the growth of pathogenic microorganisms, but do not completely destroy them. As a result, the reproduction of the infection stops, and it gradually dies.
Tetracyclines have a wide spectrum of activity, with pronounced activity against aerobic gram-positive and gram-negative bacteria. Tetracyclines are not prescribed for children under 8 years of age, since long-term use causes a number of serious complications.
The drugs of this group can be prescribed in tablet forms and in the form of injections. For the treatment of ophthalmic infections, ointments are produced, the active substance of which is tetracycline.
Medicines:
doxycycline;
minocycline;
Tetracycline;
Oxytetracycline.
Diseases for which tetracyclines are prescribed:
Macrolides
They suppress vital activity and prevent the reproduction of anaerobic and aerobic gram-positive bacteria. Preparations of this group are used in the treatment of bronchopulmonary infections, tonsillitis, otitis, scarlet fever, intestinal infections. Medicines that are included in this group:
Erythromycin;
Azithromycin;
Clarithromycin;
Spiramycin.
Penicilli
A group of antibiotics produced by the fungus Penicillium. Penicilli are active against most Gram-positive and some Gram-negative bacteria. This group of drugs:
Amoxicillin;
Augumetin;
Amoxiclav;
Flemoxin Slutab.
Cephalosporins
These are bactericidal beta-beta-lactam antibiotics that interfere with cell protein synthesis. There are 5 generations of cephalosporins. The active substance penetrates well into most body fluids, having a pronounced bactericidal effect. Cephalosporins are used for uncomplicated skin and soft tissue infections caused by staphylococcal and streptococcal bacteria. This group of drugs:
Ceftriaxone;
Cefodox;
Cefix;
Tsepefim.
Bacteria are organisms that do not live long, but in order to restore their population, they multiply rapidly, and, accordingly, quickly mutate, adapting to new living conditions. Microorganisms that survive after taking antibiotics become resistant to them. Their offspring also become immune to a particular drug.
Antibiotic resistance is a common problem of modern man, which causes serious complications. A person who has tried many antibiotics, that is, self-medicated, is at risk for patients with antibiotic resistance. Very often they die before a specialist can pick up a drug that works against a specific pathogen. Therefore, it is important to follow the recommendations of the doctor and take antibacterial agents strictly according to an individual scheme.

Explore the list of 8 groups of antibacterial drugs and get detailed information about the best antibiotics that will help get rid of various infections with a high level of effectiveness and safe for health. The use of antibiotics should be carried out under the recommendation of a doctor who will determine the dosage, duration of the course and the specific drug depending on the type of infection.
Antibacterials are medicines used to treat various infectious diseases caused by bacteria. There are several groups of antibiotics, each of which is aimed at suppressing certain types of bacteria.
One of the main tasks of an infectious disease doctor is to choose the right drug for a particular patient, taking into account the type of infection, age, the presence of allergic reactions and other factors. Listed below are the 8 groups of antibacterial drugs most widely used in medicine.
- Penicillins are the oldest group of antibiotics that were first discovered in the middle of the 20th century. They act on a wide range of bacteria and are highly effective in the treatment of many infections.
- Cephalosporins are a group of antibiotics that act on bacteria that cause infections in the respiratory tract, urinary tract, skin and teeth. They are also widely used in surgery to prevent postoperative infections.
- Macrolides are a group of antibiotics used to treat infections of the upper respiratory tract, skin and soft tissues. They are often prescribed for allergies to penicillins.
- Aminoglycosides are a group of antibiotics that act on bacteria that cause severe urinary tract, lung, bone and joint infections. They are often used to treat patients in hospitals.
- Lincosamides is a group of antibiotics used to treat infections caused by anaerobic bacteria. They can also be used as an alternative to macrolides in the treatment of respiratory or skin infections.
- Fluoroquinolones are a group of antibiotics that act on bacteria that cause urinary tract, genital, lung and skin infections. They are often prescribed as a treatment for urogenital infections.
- Tetracyclines are a group of antibiotics that act on bacteria that cause respiratory, urinary, and skin infections. They are also used to treat sexually transmitted infections.
- Carbapenems are a group of antibiotics that act on bacteria that cause severe infections, including bone, lung and hospital infections. Carbapenems are used as a last line of treatment when other antibiotics do not work.
Antibacterials: groups and best examples
There are 8 groups of antibiotics, which are classified according to their mechanism of action and chemical structure. Each group has its own specific activity and is used to treat certain infections.
The second group is cephalosporins. They are more stable in acidic environments and are more widely used for more serious infections. Particularly effective are cefotaxime, ceftriaxone, and cefepime.
The third group is macrolides. These antibiotics act on the bacterium, preventing it from multiplying. These include erythromycin, clarithromycin, and azithromycin.
The fourth group is tetracyclines. They are widely used in the treatment of various infections, including respiratory and genitourinary infections. A famous example is doxycycline.
Fifth group – aminoglycosides. These antibiotics are powerful bactericidal and are used to treat severe infections such as sepsis and pneumonia. Gentamicin, tobramycin and amikacin are the most widely used.
Sixth group – lincosamides. They are also used to treat severe infections and have anti-inflammatory effects. These include lincomycin and clindamycin.
Seventh group – carbapenems. They are powerful antibiotics and are widely used to treat infections caused by many different bacteria, including those resistant to other groups of antibiotics. Of these, the best known are imipenem and meropenem.
Eighth group – fluoroquinolones. They are effective in treating a variety of infections, including acute and chronic bronchitis, bacterial diarrhea, and urinary tract infection. These include ofloxacin, levofloxacin, and ciprofloxacin.
The above groups of antibiotics are the main ones, but there are other groups of antibacterial drugs on the market.
Group of beta-lactam antibiotics
Beta-lactam antibiotics are one of the most widely used groups of antibiotics. Their basis is the beta-lactam ring fragment in their chemical structure.
Beta-lactam drugs fall into four main categories:
- Penicillins
- Cephalosporins
- Carbapenems
- Monobactams
Penicillins are widely used to treat infections caused by various bacteria, including pneumococci, streptococci, and staphylococci. Cephalosporins are also widely used to treat infections and are usually an alternative if penicillins are ineffective or cannot be used. Carbapenems are strong antibiotics often used in the hospital to treat severe infections caused by various bacteria, including Pseudomonas and Acinetobacter. Monobactams are a relatively new class of antibiotics used to treat infections caused by Gram-negative bacteria such as Pseudomonas and Haemophilus influenzae.
Some examples of beta-lactam antibiotics: Penicillin drugs Cephalosporin drugs 0282
Group of macrolide antibiotics
Macrolide antibiotics are one of the most widely used groups antibiotics. They are used to treat various infections such as respiratory, genitourinary, gastroenterological, skin and other types of infections. The macrolide group includes drugs such as azithromycin, erythromycin, clarithromycin, and others.
The mechanism of action of macrolide antibiotics is based on the fact that they block the synthesis of proteins in the bacterial cell, which leads to its death. Also, macrolides have the properties of immunomodulators, helping to suppress inflammation and increase immunity.
The advantage of macrolides over other antibiotics is their relative safety and broad spectrum of activity. They are well tolerated by patients and usually do not cause serious side effects. However, like other antibiotics, macrolides can cause allergic reactions and intestinal dysbiosis.
- Azithromycin is considered the most effective and widely used in this group of drugs, due to its long duration of action and the fact that it can be used to treat bacterial infections of any location.
- Erythromycin is more active against gram-positive bacteria than azithromycin, but less effective against bacteria that cause urinary tract infections.
- Clarithromycin has the added benefit of better tissue and vascular penetration than other macrolides, making it more effective against respiratory tract infections.
Tetracycline antibiotic group
Tetracycline antibiotics are a group of medicines that are used to fight many types of bacteria. These antibiotics have a wide spectrum of activity and are used to treat infectious diseases such as pneumonia, urinary tract infections, skin infections, etc.
Some of the most commonly used tetracycline antibiotics include tetracycline, doxycycline, minocycline and oxytetracycline.
Like all antibiotics, tetracyclines can cause side effects and it is important to check with your doctor or pharmacist before taking these medicines. Tetracyclines are not recommended for children under 12 years of age, pregnant women and nursing mothers.
Examples of tetracycline antibiotics Available as…
Tetracycline | Tablets, capsules |
Doxycycline | Tablets, capsules , syrup |
Minocycline | Tablets, capsules |
Oxytetracycline | Tablets, capsules |
Aminoglycosis group
Aminoglycoside antibiotics are a group of bactericidal drugs that act on bacterial cells by interfering with protein synthesis. They can also produce effects on certain types of cells and tissues, but are more often used only as antibacterial drugs.
Aminoglycosides are often used to treat severe infections caused by Gram-negative bacteria. Including pathogens such as Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumoniae.
Aminoglycosides have a number of typical representatives: gentamicin, kanamycin, amikacin, streptomycin and others. Each of them has its own characteristics, designed to defeat certain types of bacteria.
Thus, aminoglycoside antibiotics remain an important group of drugs for the treatment of severe infections caused by gram-negative bacteria. Their use requires special care and only after a careful assessment of the side effects in a particular case.
Quinolone antibiotic group
Quinolone antibiotics are a group of bactericides used to treat infectious diseases. They have a wide spectrum of activity and are well tolerated by patients.
Quinolones act on bacteria by inhibiting their ability to synthesize DNA, which leads to their death. Thus, they can be used to treat infections caused by both Gram-positive and Gram-negative bacteria.
- Examples of quinolone antibiotics:
- Ciprofloxacin
- Ofloxacin
- Levofloxacin
- Norfloxacin
- Moxifloxacin
9002 7
Quinolones can be used to treat infections of the respiratory tract, urinary tract, skin infections, infections of the gastrointestinal tract, as well as to prevent infections in immunocompromised states.
Group of glycopeptides
Glycopeptides is a group of antibiotics that are intended for the treatment of infections caused by gram-positive bacteria. Usually used to treat pathogens that cause infections of the skin, respiratory tract, bones and purulent blood infections. They are relatively new drugs that have become available for use only recently.
Preparations of the glycopeptide group:
- Vancomycin is one of the most commonly used representatives of the glycopeptide group. It is widely used to treat infections caused by bacteria resistant to other types of antibiotics. It is recommended to be used if other drugs have no effect.
- Telavancin – effective against most gram-positive bacteria, including methicillin-resistant strains of staphylococci. It has a fast action and a wide spectrum of action.
- Oritavancin – is prescribed for the treatment of skin and soft tissue infections, as well as pneumonia in patients suffering from chronic diseases. It is well tolerated and has minimal side effects.
Contraindications and side effects:
Preparations of the glycopeptide group have several contraindications and possible side effects. Some of them can be toxic to the kidneys and/or liver, which can lead to serious complications. Allergic reactions, nausea, vomiting, and diarrhea may also occur.
It is necessary to consult a doctor before starting treatment with drugs of the glycopeptide group. In addition, the recommended dose and duration of treatment should not be exceeded.
Lincosamide group
Lincosamides are a group of antibiotics that are active against gram-positive bacteria, including staphylococci, streptococci and pneumococci. They are synthesized by microorganisms that produce them as a defense against other bacteria. Lincosamides are used to treat infections caused by these bacteria, including infections of the skin, respiratory tract, and urogenital system.
The main member of the group is erythromycin, which has a wide spectrum of action and is often used to treat upper respiratory tract infections. Also in the group of lincosamides are clarithromycin, which has greater activity against gram-negative bacteria, as well as azithromycin, which has a long half-life and can be taken once.
- Benefits of lincosamides:
- broad spectrum;
- good tolerance;
- choice of dosage and formulation;
- few side effects.
Disadvantages:
- High price compared to some other groups of antibiotics;
- Development of resistance to this group of antibiotics.
Polymyxin group
Polymyxin is a group of antibiotics that were discovered in 1947 year. They have a broad spectrum of activity and are active against many Gram-negative bacteria such as Escherichia coli, Salmonella, Klebsiella pneumoniae, Pseudomonas aeruginosa.
Polymyxins may be used to treat pneumonia, urinary tract infections, sepsis, skin infections, and other infections caused by Gram-negative bacteria.
Despite their toxicity, polymyxins remain an important tool in the fight against infections caused by many Gram-negative bacteria that have become resistant to other antibiotics. They should only be used after other antibiotics have been tried and failed or cannot be used for other reasons.
Antibacterial Azithromycin
Azithromycin is a macrolide antibiotic used to treat a variety of infections caused by bacteria, including pneumonia, bronchitis, sinusitis, tracheitis, urinary tract infections, skin infections, and other conditions. This drug has a wide spectrum of action and is considered one of the most effective antibiotics.
Azithromycin is available in several forms: tablets, capsules, suspension and powder for intravenous solution. The main advantage of this drug is its short course of treatment – usually it is enough to take tablets or capsules for 3-5 days. It is also generally well tolerated and has few side effects.
It is important to remember that azithromycin is an antibiotic and should only be taken with a doctor’s prescription. Do not exceed the recommended dose and duration of the drug. If side effects occur, you should immediately consult your doctor.
- Benefits:
- Broad spectrum;
- Short course of treatment;
- Minimum number of side effects.
- Purpose:
- Treatment of infections of the respiratory tract, genitourinary system, skin infections, etc.
Antibacterial drug Amoxicillin
Amoxicillin is an antibacterial drug that belongs to the group of semi-synthetic penicillins. It is widely used to treat various infections caused by bacteria.
The mechanism of action of amoxicillin is based on the fact that it destroys bacteria by inhibiting the synthesis of their cell walls. The drug is active against many types of bacteria, including staphylococci, streptococci, pneumococci, salmonella, shigella and others.
Amoxicillin is taken orally, in one dose or divided into several doses. The dosage and duration of the course of treatment depend on the type of infection and its severity, as well as on the age and weight of the patient.
Side effects of amoxicillin include allergic reactions, diarrhea, nausea and vomiting. In addition, the drug may interact with certain other drugs.
- Amoxicillin is one of the most common and most effective antibacterial drugs.
- The drug can be prescribed to adults and children, including newborns.
- Although highly effective, amoxicillin cannot treat infections caused by viruses, fungi, and protozoa.
If you are being treated with amoxicillin, follow your doctor’s instructions and do not stop treatment prematurely, even if the symptoms of the infection have gone. This will help prevent recurrence of the infection and reduce the risk of developing bacterial resistance.
Antibacterial drug Levofloxacin
Levofloxacin is a fluoroquinolone antibiotic used to treat infections caused by susceptible organisms. It penetrates into bacterial cells and disrupts their viability by blocking DNA synthesis.
Levofloxacin is effective against a wide range of bacteria, including Gram-positive, Gram-negative, weather-resistant and anaerobic organisms.
Levofloxacin is most commonly used to treat bacterial infections of the respiratory tract, genitourinary system, skin, soft tissues, and bones. It also has an anti-inflammatory effect, so it can be used to treat acute bronchi and exacerbations of chronic lung diseases.
- Levofloxacin is not recommended for children under 18 years of age, pregnant or lactating women, or patients with kidney or liver problems.
