How does CellCept affect pregnancy and fertility. What infections are transplant patients at risk for while taking mycophenolate mofetil.

Understanding CellCept: An Essential Antirejection Medication

CellCept, also known by its generic name mycophenolate mofetil, is a crucial medication in the world of organ transplantation. It plays a vital role in preventing organ rejection in patients who have received kidney, heart, or liver transplants. But what exactly does this medication do, and how does it work?

CellCept functions as an immunosuppressant, effectively dampening the body’s immune response. When a patient receives a transplanted organ, their immune system may perceive it as a foreign invader and attempt to attack it. This natural response, while normally protective, can lead to rejection of the transplanted organ. CellCept works to prevent this by suppressing the immune system’s ability to mount an attack against the new organ.

It’s important to note that CellCept is not used in isolation. It’s typically prescribed as part of a combination therapy, often alongside other immunosuppressive medications such as cyclosporine and corticosteroids. This multi-pronged approach helps to maximize the chances of successful organ transplantation while minimizing the risk of rejection.

Critical Safety Information: What Patients Need to Know

While CellCept is an invaluable tool in transplant medicine, it comes with several important safety considerations that patients must be aware of. These potential side effects and risks are crucial for patients to understand and discuss with their healthcare providers.

Pregnancy and Fertility Concerns

One of the most significant concerns associated with CellCept is its impact on pregnancy and fertility. Women who are pregnant or planning to become pregnant should be particularly cautious when considering this medication.

• Increased risk of miscarriage, especially in the first trimester
• Higher likelihood of birth defects in babies born to mothers taking CellCept
• Necessity for effective contraception while taking the medication and for 6 weeks after discontinuation
• Potential interference with hormonal birth control methods

How does CellCept affect male fertility and contraception? Men taking CellCept should also take precautions if their partner could become pregnant. They should use effective contraception during treatment and for at least 90 days after stopping the medication.

Cancer Risk and CellCept

Another crucial aspect of CellCept’s safety profile is its association with an increased risk of certain cancers. Patients taking this medication should be vigilant about monitoring for potential signs of cancer development.

• Higher risk of lymphoma and other cancers, particularly skin cancer
• Importance of regular skin checks and reporting any unusual skin changes
• Need to report symptoms such as unexplained fever, prolonged tiredness, weight loss, or lymph node swelling

Why is skin cancer a particular concern for CellCept users? The immunosuppressive effects of CellCept can make the body less able to fight off abnormal cell growth, including that of skin cancer cells. Additionally, transplant patients may be more susceptible to UV damage due to their medications, further increasing the risk.

Infection Risks: A Major Concern for CellCept Users

Perhaps one of the most significant risks associated with CellCept use is the increased susceptibility to infections. By suppressing the immune system to prevent organ rejection, CellCept also leaves patients more vulnerable to various types of infections, some of which can be severe or even life-threatening.

Viral Infections: A Particular Threat

Viral infections pose a significant risk to patients taking CellCept. The weakened immune system can allow dormant viruses to reactivate or make it easier for new viral infections to take hold.

• Shingles and other herpes infections
• Cytomegalovirus (CMV), which can cause serious tissue and blood infections
• BK virus, potentially affecting kidney function
• Hepatitis B and C viruses, impacting liver function
• Increased susceptibility to COVID-19

How can patients protect themselves from these viral threats? Regular monitoring, prompt reporting of symptoms, and following recommended vaccination schedules (as advised by their transplant team) are crucial steps in managing this risk.

Progressive Multifocal Leukoencephalopathy (PML)

One of the most serious potential complications associated with CellCept use is Progressive Multifocal Leukoencephalopathy (PML), a rare but potentially fatal brain infection. PML is caused by the reactivation of the JC virus, which is normally kept in check by a healthy immune system.

What are the symptoms of PML that patients should watch for? Symptoms can include changes in vision, speech, or balance, confusion, and personality changes. Any such symptoms should be reported to a healthcare provider immediately.

Managing CellCept: Best Practices for Patients

Given the potential risks associated with CellCept, it’s crucial for patients to follow certain best practices to maximize the benefits of the medication while minimizing risks.

1. Adhere strictly to the prescribed dosage and schedule
2. Attend all follow-up appointments and undergo regular monitoring tests
3. Report any unusual symptoms or side effects promptly
4. Practice good hygiene and take precautions to avoid infections
5. Use effective contraception as directed by your healthcare provider
6. Avoid excessive sun exposure and use appropriate sun protection
7. Do not stop taking CellCept without consulting your transplant team

Why is it crucial not to stop CellCept abruptly? Sudden discontinuation of CellCept can significantly increase the risk of organ rejection, potentially jeopardizing the success of the transplant.

Pregnancy Registry: A Vital Resource for CellCept Users

Given the significant risks associated with CellCept use during pregnancy, a dedicated registry has been established to gather information about pregnancies in women taking this medication. This registry serves as a crucial resource for both patients and healthcare providers.

How can patients participate in the Mycophenolate Pregnancy Registry? Pregnant women taking CellCept can report their pregnancy to the registry by calling 1-800-617-8191 or visiting the Risk Evaluation and Mitigation Strategy (REMS) website at mycophenolateREMS.com.

The data collected through this registry helps to better understand the effects of CellCept on pregnancy outcomes, potentially leading to improved guidelines and safer use of the medication in the future.

Beyond CellCept: Alternative Antirejection Medications

While CellCept is a widely used and effective antirejection medication, it’s not the only option available. In some cases, particularly if a patient experiences severe side effects or if pregnancy is desired, alternative medications may be considered.

What are some alternatives to CellCept for preventing organ rejection? Other immunosuppressive medications that may be used include tacrolimus, sirolimus, everolimus, and azathioprine. Each of these medications has its own benefits and potential side effects, and the choice of medication is typically tailored to the individual patient’s needs and circumstances.

It’s important to note that any changes to an antirejection regimen should only be made under the close supervision of a transplant specialist. Switching medications carries its own risks and must be carefully managed to ensure continued protection against organ rejection.

Living with CellCept: Balancing Benefits and Risks

For many transplant recipients, CellCept plays a crucial role in preventing organ rejection and maintaining the health of their transplanted organ. However, living with this medication requires a careful balance between its benefits and potential risks.

How can patients optimize their quality of life while taking CellCept? Here are some strategies:

• Maintain open communication with your transplant team about any concerns or side effects
• Adopt a healthy lifestyle, including a balanced diet and regular exercise as approved by your doctor
• Stay up-to-date with recommended vaccinations and health screenings
• Build a strong support network of family, friends, and fellow transplant recipients
• Consider joining support groups or counseling to manage the emotional aspects of transplant and long-term medication use

By staying informed, vigilant, and proactive in their care, patients can maximize the benefits of CellCept while minimizing its potential risks, contributing to long-term transplant success and overall well-being.

Navigating the Healthcare System: Tips for CellCept Users

Managing a complex medication regimen like CellCept within the healthcare system can be challenging. Here are some tips to help patients navigate this process more effectively:

1. Keep a detailed record of all medications, including dosages and schedules
2. Maintain a list of all healthcare providers involved in your care, including contact information
3. Familiarize yourself with your insurance coverage and any prior authorization requirements for CellCept
4. Consider using a medication reminder app or system to ensure timely dosing
5. Learn about patient assistance programs that may help with medication costs
6. Prepare questions in advance of medical appointments to make the most of your time with healthcare providers

How can patients ensure continuity of care across different healthcare providers? It’s crucial to keep all providers informed about your complete medication regimen, including CellCept. Consider designating your transplant center as the central point of contact for coordinating your care.

By taking an active role in managing their healthcare, patients can help ensure they receive the best possible care and support while taking CellCept.

Future Directions: Research and Development in Transplant Medicine

While CellCept has been a mainstay of transplant medicine for many years, research into new and improved antirejection medications continues. Scientists are working to develop drugs that can provide effective immunosuppression with fewer side effects.

What are some promising areas of research in transplant medicine? Some exciting developments include:

• More targeted immunosuppressive drugs that affect only specific parts of the immune system
• Techniques to induce immune tolerance to the transplanted organ, potentially reducing or eliminating the need for long-term immunosuppression
• Improved methods for monitoring the immune system to allow for more precise medication dosing
• Development of bioengineered organs that may be less likely to trigger rejection

How might these advances impact patients currently taking CellCept? While these developments are promising, it’s important to note that bringing new treatments to market is a long process. Patients should continue to work closely with their healthcare providers to manage their current medication regimen while staying informed about potential future options.

As research progresses, the hope is that future transplant recipients may have access to even more effective and safer antirejection strategies, building on the foundation laid by medications like CellCept.

Medication Guide Announcement

Support & Resources

What it Treats

• CELLCEPT^® (mycophenolate mofetil) is a prescription medicine to prevent rejection (antirejection medicine) in people who have received a kidney, heart or liver transplant. Rejection is when the body’s immune system perceives the new organ as a “foreign” threat and attacks it.
• CELLCEPT is used with other medicines containing cyclosporine and corticosteroids.

Important Safety Information

What is the most important information I should know about CELLCEPT?

CELLCEPT can cause serious side effects, including:

Increased risk of loss of a pregnancy (miscarriage) and higher risk of birth defects. Females who take CELLCEPT during pregnancy have a higher risk of miscarriage during the first 3 months (first trimester), and a higher risk that their baby will be born with birth defects.

• If you are a female who can become pregnant, your doctor must talk with you about acceptable birth control methods (contraceptive counseling) to use while taking CELLCEPT. You should have 1 pregnancy test immediately before starting CELLCEPT and another pregnancy test 8 to 10 days later. Pregnancy tests should be repeated during routine follow-up visits with your doctor. Talk to your doctor about the results of all of your pregnancy tests. You must use acceptable birth control during your entire CELLCEPT treatment and for 6 weeks after stopping CELLCEPT, unless at any time you choose to avoid sexual intercourse (abstinence) with a man completely. CELLCEPT decreases blood levels of the hormones in birth control pills that you take by mouth. Birth control pills may not work as well while you take CELLCEPT, and you could become pregnant. If you take birth control pills while using CELLCEPT you must also use another form of birth control. Talk to your doctor about other birth control methods that you can use while taking CELLCEPT.
• If you are a sexually active male whose female partner can become pregnant while you are taking CELLCEPT, use effective contraception during treatment and for at least 90 days after stopping CELLCEPT.
• If you plan to become pregnant, , talk with your doctor. Your doctor will decide if other medicines to prevent rejection may be right for you.
• If you become pregnant while taking CELLCEPT, do not stop taking CELLCEPT. Call your doctor right away. You and your doctor may decide that other medicines to prevent rejection may be right for you. You and your doctor should report your pregnancy to the Mycophenolate Pregnancy Registry either:
• by phone at 1-800-617-8191 or
• o by visiting the Risk Evaluation and Mitigation Strategy (REMS) website at mycophenolateREMS. com

The purpose of this registry is to gather information about the health of you and your baby.

Increased risk of getting certain cancers. People who take CELLCEPT have a higher risk of getting lymphoma, and other cancers, especially skin cancer. Tell your doctor if you have:

• unexplained fever, prolonged tiredness, weight loss or lymph node swelling
• brown or black skin lesion with uneven borders, or one part of the lesion does not look like the other
• a change in the size and color of a mole
• a new skin lesion or bump
• any other changes to your health

Increased risk of getting serious infections. CELLCEPT weakens the body’s immune system and affects your ability to fight infections. Serious infections can happen with CELLCEPT and can lead to hospitalizations and death. These serious infections can include:

• Viral infections. Certain viruses can live in your body and cause active infections when your immune system is weak. Viral infections that can happen with CELLCEPT include:
  • shingles, other herpes infections, and cytomegalovirus (CMV). CMV can cause serious tissue and blood infections
  • BK virus. BK virus can affect how your kidney works and cause your transplanted kidney to fail
  • hepatitis B and C viruses. Hepatitis viruses can affect how your liver works. Talk to your doctor about how hepatitis viruses may affect you
  • COVID-19

• A brain infection called Progressive Multifocal Leukoencephalopathy (PML). In some patients, CELLCEPT may cause an infection of the brain that may cause death. You are at risk for this brain infection because you have a weakened immune system. Call your doctor right away if you have any of the following symptoms:
  • weakness on one side of the body
  • you do not care about things that you usually care about (apathy)
  • you are confused or have problems thinking
  • you can not control your muscles

• Fungal infections. Yeasts and other types of fungal infections can happen with CELLCEPT and can cause serious tissue and blood infections (See “What are the possible side effects of CELLCEPT?”).

Clinical and pharmacological group: immunosuppressive drug Pharmacotherapeutic group: Immunosuppressive agent Pharmacological action Immunosuppressive agent. Mycophenolate mofetil (MMF) is the 2-morpholinoethyl ester of mycophenolic acid (MPA). MPA is a potent, selective, non-competitive and reversible inhibitor of inosine monophosphate dehydrogenase (IMPDH) that inhibits de novo synthesis of guanosine nucleotides . The mechanism by which MPA inhibits the enzymatic activity of IMPDH appears to be due to the fact that MPA structurally mimics both the nicotinamide dinucleotide phosphate co-factor and the catalyzing water molecule. This prevents the oxidation of IMP to xanthose-5-monophosphate, the most important step in the biosynthesis of guanosine nucleotides de novo. MPA has a more pronounced cytostatic effect on lymphocytes than on other cells, since the proliferation of T- and B-lymphocytes is very dependent on de novo purine synthesis, while other types of cells can switch to bypass metabolic pathways. Pharmacokinetics After oral administration, there is a rapid and complete absorption and complete first pass metabolism of MMF with the formation of the active metabolite – MPA. Oral bioavailability of MMF, according to area AUC IFC is, on average, 94% of that when administered intravenously. After oral administration, plasma concentrations of MMF are not determined (below the detection threshold – 0.4 μg / ml). In the early post-transplant period (up to 40 days after kidney, heart or liver transplantation), the average AUC values ​​were approximately 30% lower, and C max approximately 40% lower than in the late post-transplant period (3-6 months after transplant). Food intake does not affect the degree of absorption of MMF (UC IFC ) when used at a dose of 1. 5 g 2 times / day in patients after kidney transplantation. However, C max MFC when taking mycophenolate mofetil with meals is reduced by 40%. Typically, approximately 6-12 hours after ingestion of mycophenolate mofetil, a secondary increase in plasma MFC concentrations is observed, indicative of hepatic recirculation of MMF. With the simultaneous use of cholestyramine, the AUC of MFC is reduced by approximately 40%, which indicates an interruption of the hepato-intestinal recirculation. At clinically relevant concentrations, MPA is 97% bound to plasma albumin. MPA is metabolized mainly by glucuronyl transferase (UGT gene isoform 1A9) to form the pharmacologically inactive phenolic glucuronide MPA (MPCG). In vivo, MFC is converted back to free MFC during hepato-intestinal recycling to form an acylglucuronide, which has pharmacological activity and may be the cause of some of the side effects of MFC (diarrhea, leukopenia). After oral administration of radioactively labeled MMF, 93% of the dose is excreted in the urine, 6% in the feces. Most (about 87%) of the administered dose is excreted in the urine as MFCG. Minor amounts of MMF (<1% of the dose) are excreted in the urine as MFC. Clinically detectable concentrations of MPA and MFCG are not removed by hemodialysis. However, at higher concentrations of MFCG (>100 µg/mL), some of it may be removed. Bile acid sequestrants such as cholestyramine reduce AUC IFC , interrupting hepato-intestinal recirculation. The distribution of MPA is dependent on several transporters: the organic anion transport polypeptide (TPOA) and the multidrug resistance-associated protein-2 (BAMLU-2). TPOA, BAMLU-2 isoforms, as well as breast cancer resistance protein (BRRM) are transporters associated with glucuronide excretion through bile. The multidrug resistance-1 protein may also be involved in the transport of MFC, but its participation is limited to the absorption process. MPA and its metabolites have the potential to react with organic anion transporters in the kidneys. Indications of the active substances of the drug Mycophenolate mofetil Mycophenolate mofetil is used in combination therapy with cyclosporine and corticosteroids.

Co-administration with azathioprine. Children with body surface area <1.5 m 2 (approximate child age under 14). Pregnancy, breastfeeding period. Women of childbearing potential who are not using highly effective contraceptive methods. Women of childbearing potential without a previous pregnancy test to rule out inadvertent use of mycophenolate mofetil during pregnancy. With caution: diseases of the gastrointestinal tract in the acute phase. Switching from combination therapy, including immunosuppressants that have an effect on the hepato-intestinal recycling of MFC, such as cyclosporine, to therapy with drugs that lack this effect, such as tacrolimus, sirolimus, and belatacept, and vice versa. Simultaneous use of drugs that affect the hepato-intestinal cycle of MPA, for example, colestyramine, sevelamer, antibiotics, and glucuronidation, for example, isavuconazole. Use in pregnancy and lactation Contraindicated in pregnancy (due to the mutagenic and teratogenic potential of mycophenolate mofetil). The use of mycophenolate mofetil is contraindicated during breastfeeding due to the possibility of serious adverse reactions in breastfed infants. The use of mycophenolate mofetil is contraindicated in women of childbearing potential who are not using highly effective contraceptive methods. Before starting therapy, patients with reproductive potential should be informed about the increased risk of fetal death and congenital malformations; consultation should be held on measures to prevent pregnancy and its planning. Use in impaired renal function In kidney transplant patients with severe chronic renal failure (glomerular filtration rate less than 25 ml / min / 1.73 m 2 ) outside the immediate post-transplant period, doses above 1 g should be avoided 2 times/day Dose adjustment is not recommended in patients with delayed renal graft function, but such patients require close medical supervision. Use in children Use is contraindicated in children with a body surface area <1. 5 m 2 (estimated children under 14 years of age). In children with body surface area >1.5 m 2 mycophenolate mofetil is used to prevent acute graft rejection after allogeneic kidney transplantation. Use in the elderly Elderly patients (≥65 years) may have an increased risk of adverse events such as certain infections (including tissue invasive forms of overt cytomegalovirus infection), gastrointestinal bleeding and pulmonary edema compared with younger patients . Special instructions Patients taking mycophenolate mofetil have an increased risk of developing lymphomas and other malignant tumors, in particular skin cancer. Limit exposure to the sun and ultraviolet rays by wearing appropriate protective clothing and using sunscreens with a high protection factor. With the use of mycophenolate mofetil, there is an increased risk of developing opportunistic infections (bacterial, fungal, viral and protozoal), fatal infections and sepsis. Such cases include reactivation of a latent viral infection, such as hepatitis B or C, or an infection caused by polyomaviruses (VC-associated nephropathy, JC-virus-associated PML). Cases of hepatitis due to reactivation of hepatitis B or C viruses have been reported in patients carrying hepatitis B or C viruses receiving immunosuppressive therapy. These infections are often associated with a high overall immunosuppressive burden and can lead to serious impairment or death, which should be considered in the differential diagnosis of patients with immunosuppression and worsening renal function or neurological symptoms. Cases of hypogammaglobulinemia in recurrent infections have been observed with the use of mycophenolate mofetil in combination with other immunosuppressants. In some of these cases, switching from mycophenolate mofetil to an alternative immunosuppressant resulted in normalization of serum IgG levels. Serum immunoglobulin levels should be measured in patients with recurrent infections receiving mycophenolate mofetil. With sustained, clinically significant hypogammaglobulinemia, appropriate clinical measures should be applied, taking into account the possible cytostatic effects that MFC has on T and B lymphocytes. There are data on the development of bronchiectasis in adults and children who received mycophenolate mofetil in combination with other immunosuppressants. In some of these cases, switching from mycophenolate mofetil to another immunosuppressant resulted in a reduction in respiratory symptoms. The risk of developing bronchiectasis may be associated with hypogammaglobulinemia or with direct effects on the lungs. There are isolated reports of interstitial lung disease and pulmonary fibrosis, some of which have been fatal. It is recommended to evaluate patients with persistent pulmonary symptoms such as cough and dyspnea. Cases of PCCA have been observed in patients taking mycophenolate mofetil in combination with other immunosuppressive drugs. The mechanism for the development of PCCA with the use of mycophenolate mofetil is not known, as well as the contribution of other immunosuppressants and their combination. In some cases, PKKA was reversible after reduction in the dose of mycophenolate mofetil or its withdrawal. However, in transplant patients, decreased immunosuppression may compromise the graft. Patients receiving MMF should be advised to report any signs of infection, sudden onset of bruising, bleeding, or other signs of bone marrow depression to their physician immediately. In the treatment of MMF, it is necessary to determine the expanded blood formula during the first month weekly, during the second and third months of treatment – 2 times a month, and then during the first year – monthly. Particular attention should be paid to the possibility of developing neutropenia. Neutropenia may be due to both MMF and other drugs, viral infections, or a combination of these causes. If neutropenia occurs (absolute neutrophil count <1.3×10 3 /µl) treatment with MMF should be interrupted or the dose reduced while closely monitoring these patients. Patients receiving mycophenolate mofetil should not donate blood during treatment and for at least 6 weeks after the last dose. Vaccination may be less effective during treatment with MMF; Live attenuated vaccines should be avoided. Influenza vaccination can be given according to national guidelines. Taking MMF may be accompanied by adverse reactions from the gastrointestinal tract (ulceration of the gastrointestinal mucosa, gastrointestinal bleeding, gastrointestinal perforation). Caution should be exercised when using MMF in patients with acute gastrointestinal disease. MMF is an inhibitor of IMPDH and should not be used in patients with rare genetically determined hypoxanthine-guanine phosphoribosyltransferase deficiency (Lesch-Nychen and Kelly-Sigmiller syndromes). Mycophenolate is a potent human teratogen. There have been cases of spontaneous abortions (with a frequency of 45% to 49%) and congenital malformations (estimated frequency of 23% to 27%) with the use of MMF during pregnancy. The healthcare provider should ensure that a woman taking mycophenolate understands the risk of harm to the baby, the need for effective contraception, and the need to consult a healthcare provider immediately if pregnancy is likely. Women of childbearing potential should use at least one reliable method of contraception before starting, during treatment, and for 6 weeks after stopping therapy with mycophenolate mofetil if abstinence from sexual activity is not possible. It is preferable to use 2 complementary methods of contraception at the same time to minimize the possibility of ineffective contraception and the onset of an unplanned pregnancy. Sperm donation is not permitted during the treatment period and for 90 days after the last dose of mycophenolate mofetil. Influence on the ability to drive vehicles and mechanisms During the period of treatment, patients should avoid driving vehicles and other activities that require a high concentration of attention and speed of psychomotor reactions. Drug Interactions Higher plasma concentrations of acyclovir have been observed with concomitant use of MMF and acyclovir than with acyclovir alone. Changes in pharmacokinetic parameters (namely, an increase in the concentration of MFCG by 8%) MFCG (phenolic glucuronide MPA) were minimal and are not considered clinically significant. Since plasma concentrations of MFCG, like aciclovir, are increased in renal failure, it is possible that MMF and aciclovir (or its prodrugs, such as valaciclovir) compete for tubular secretion, which may lead to a further increase in the concentration of both drugs. Co-administration of mycophenolate mofetil with antacids (aluminum and magnesium hydroxide) and with proton pump inhibitors (lansoprazole and pantoprazole) has been associated with a decrease in MPA levels. However, there was no significant difference between the rates of graft rejection in patients taking mycophenolate mofetil with and without proton pump inhibitors. This conclusion theoretically applies to all antacids, since when magnesium and aluminum hydroxide are taken simultaneously with mycophenolate mofetil, the concentration of MFC decreases to a much lesser extent than when mycophenolate mofetil is taken simultaneously with proton pump inhibitors. Caution should be exercised when using drugs that affect the hepato-intestinal circulation (eg cholestyramine, cyclosporine, antibiotics) due to their potential to reduce the effectiveness of mycophenolate mofetil. Caution should be exercised when co-administering cholestyramine due to the potential for decreased efficacy of mycophenolate mofetil. MMF does not affect the pharmacokinetics of ciclosporin. However, with the termination of the simultaneous use of cyclosporine, an increase in AUC 9 should be expected.0088 IFC by about 30%. Cyclosporine interferes with the hepatic intestinal recycling of MPA, which may result in a reduction in MPA exposure of approximately 30-50% in kidney transplant patients receiving mycophenolate mofetil and cyclosporine. On the contrary, when switching patients from cyclosporine therapy to therapy with immunosuppressants that do not affect the hepatic intestinal recycling of MPA, a change in MPA exposure should be expected. Antibiotics that kill bacteria that produce β-glucuronidase in the intestine (eg, antibiotics from the group of aminoglycosides, cephalosporins, fluoroquinolones, and penicillins) may interfere with the hepatic intestinal recycling of MFCG/MFK, which, in turn, may lead to a decrease in systemic exposure to IFC. When used simultaneously with drugs that inhibit MPA glucuronidation (isavuconazole and telmisartan), its exposure may increase. In patients not taking cyclosporine, concomitant use of mycophenolate mofetil and rifampicin resulted in an 18-70% reduction in MPA exposure (AUC 0-12 ). It is recommended to control the exposure of MPA and adjust the dose of mycophenolate mofetil to maintain the clinical effect when used together. Simultaneous use of sevelamer and MPA in adults and children reduced C max and AUC 0-12 MFC by 30% and 25%, respectively, without any clinical consequences (for example, graft rejection). However, it is recommended that mycophenolate mofetil be taken at least 1 hour before or 3 hours after taking sevelamer to minimize the effect on MPA absorption. There are no data on the use of mycophenolate mofetil with phosphate binders other than sevelamer. Liver transplant patients initiated on mycophenolate mofetil and tacrolimus therapy had no significant effect on AUC and C max MFC (active metabolite of mycophenolate mofetil). In contrast, in patients with a liver transplant after multiple doses of mycophenolate mofetil at a dose of 1.5 g 2 times / day, the AUC of tacrolimus increased by approximately 20%. In kidney transplant patients, the use of mycophenolate mofetil did not appear to affect tacrolimus concentrations. Live attenuated vaccines should not be given to patients who are immunosuppressed. Antibody formation in response to other vaccines may be reduced. Keep If you want to place a link to the description of this drug – use this code Mycophenolate mofetil .

Pharmacological action

Pharmacological action –

immunosuppressive .

Characteristic

White or off-white crystalline powder, sparingly soluble in water (solubility increases with acidification of the medium), soluble in methanol, partially soluble in ethanol, very soluble in acetone.

Pharmacology

Selectively inhibits inosine monophosphate dehydrogenase and inhibits the synthesis of nucletoid guanosine de novo. It has a pronounced cytostatic effect on lymphocytes, inhibits their proliferation in response to both mitogenic and allospecific stimulation. It also inhibits the formation of antibodies by B-lymphocytes. Prevents glycosylation of lymphocytic and monocytic glycoproteins involved in intercellular interaction with the endothelium, and reduces the migration of lymphocytes to the foci of inflammation and transplant rejection, blocks the effect of mononuclear cells on DNA synthesis and proliferation.

When taken orally, it is rapidly absorbed and completely presystemically hydrolyzed, forming mycophenolic acid (active metabolite). Its absolute bioavailability is 94% (mycophenolate mofetil is practically not detected in plasma). The time to reach max “> C _max (24.5 μg / ml) is 0.8–0.9 hours. 50% lower. Mycophenolic acid is 97% bound to plasma albumin. The average volume of distribution is 3.6-4.0 l / kg. In tissues, it turns into a glucuronide (binds to albumin – 82%). At high plasma concentrations of glucuronide, competition for protein binding sites is possible. After 6–12 hours, a second peak is determined in the blood, due to enterohepatic circulation. T _1/2 is 17.9 h, plasma Cl is 193 ml/min. About 87% of the administered dose is excreted by the kidneys, 6% by the intestines. Mainly glucuronide is excreted, 3 more metabolites and less than 1% of mycophenolic acid are found in the urine.

In combination with azathioprine and cyclosporine, as well as with an induction course of antithymocyte globulin, reduces the incidence of adverse outcomes in the first 6 months after transplantation.

Use of the substance Mycophenolate mofetil

Prevention of acute organ rejection and treatment of allogeneic transplant rejection (in combination with cyclosporine and glucocorticoids).

Contraindications

Hypersensitivity, exacerbation of peptic ulcer of the stomach and duodenum and other diseases of the gastrointestinal tract, pregnancy, breast-feeding, childhood.

Use in pregnancy and lactation

FDA fetal category D.

Side effects of Mycophenolate mofetil substance

Nausea, vomiting, diarrhea, constipation, leukopenia or leukocytosis, anemia, thrombocytopenia , increased frequency of infectious and septic complications; headache, insomnia, tremor, fever, asthenia, lumbago, hypertension, cough, pharyngitis, shortness of breath, peripheral edema, oropharyngeal candidiasis, hematuria, tubular necrosis, impotence, acne, hyper- or hypokalemia, hyperglycemia, hypophosphatemia, hypercholesterolemia, allergic reactions, rash, pruritus.

Interactions

Probenecid and other drugs that affect tubular secretion increase the plasma concentration of mycophenolic acid. Antacids containing magnesium and aluminum hydroxides reduce absorption. Drugs that change the flora of the gastrointestinal tract can disrupt the enterohepatic circulation. May reduce the effectiveness of oral contraception. Azathioprine increases the risk of developing lymphomas, especially of the skin.

Overdose

Symptoms: increased frequency of gastrointestinal and hematological (particularly neutropenia) side effects.

Treatment: dose reduction or drug withdrawal. To accelerate excretion, bile acid sequestrants may be prescribed. Small amounts of glucuronide can be removed by hemodialysis (mycophenolic acid is not dialyzed).

Dosage and administration

Inside . For the prevention of graft rejection – 1 g 2 times / day (the initial dose should be taken within 3 days after transplantation) in combination with corticosteroids and cyclosporine. For the treatment of rejection reaction refractory to other therapies, 1.5 g 2 times / day, also in combination.

Precautions

It is necessary to take into account the possibility of an increased risk of developing lymphoproliferative processes (about 1% of cases), regularly monitor the composition of peripheral blood, with a decrease in the number of neutrophils below 1.3 10 ³ /μl, dose reduction or a break in treatment is indicated ( and appropriate therapy). In case of a decrease in the glomerular filtration rate below 25 ml / min, it is not recommended to use more than 2 times a day. During and within 6 weeks after the end of the course, reliable contraception is required; if pregnancy does occur, termination should be considered.
