drugs of choice for treatment (part 1) // Pharmacology

This is a chronic recurrent dermatosis of unknown etiology or chronic lichen scaly. The disease is not contagious, unlike other types of lichen (for example: infectious pink or pityriasis).

Psoriasis is characterized by frequent relapses, skin rashes in the form of cracking scaly papules, which are usually not accompanied by itching. Men get sick more often than women. An exacerbation can be provoked by: emotional disorders (stress, hidden anger, resentment, depression, anxiety), mechanical skin injuries, severe sunburn, physical overload, or taking certain medications. Weather conditions strongly influence the course of the disease, cold dry weather increases the activity of the disease, and hot, humid and sunny weather contributes to its attenuation, which greatly alleviates the condition of most patients. The most common sites affected are the elbows, palms of the hands, knees, lower back, scalp, upper pelvic bones, lower legs, calves, thighs, and genital area. In addition to the skin (the main organ of the lesion), other organs and systems of the body (nails, joints) can be affected.

There are several types of psoriasis: pustular, arthropathic, exudative, verrucous, plaque, vesicular, patchy, guttate, inverse, seborrheic, etc.

The exact causes of psoriasis have not been finally established, but it is known that hereditary predisposition plays the main role. In the body of such patients, various disorders of the endocrine and nervous systems occur, metabolic failures (mainly carbohydrate and fat metabolism disorders), a focus of chronic infection or disturbances in the adequate functioning of the liver is possible. The occurrence of the disease is explained by disorders in the immune system, fermentopathy and other factors that regulate the division of skin cells.

The trigger mechanism of the disease is the processes occurring in the epidermis. In the basal (deep) layer of the epidermis, keratinocytes are formed – these are immature skin cells that produce keratin – a hard protein that is the building material for hair, nails and skin, and make up the bulk of the skin epidermis. Normally, keratinocytes grow and move from the lower layer to the surface of the skin almost imperceptibly. The death of keratinocytes is a programmed process that is the logical conclusion of the life path of these epithelial tissue cells. For all the time of a person’s life, the skin is constantly updated (about 1000 times). At a young age, the process of cell advancement from the basement membrane to desquamation from the surface is ˜25 days, later this process slows down and ranges from 56 to 72 days. In patients with psoriasis, keratinocytes multiply very rapidly and move from the basal layer to the surface in about 4 days. The skin cannot get rid of these cells fast enough. in a short period of time, their number increases sharply. This, in turn, leads to the formation of compacted, dry areas on the skin, with the formation of spots (areas) that are clearly defined, pinkish or deep red, excessively dry, raised above the surface of the skin and covered with silvery, intensely scaly scales (rejected thin plates of keratinized epithelium), the so-called. papules.

Papules are by nature sites of chronic inflammation and excessive proliferation of lymphocytes, macrophages and keratinocytes of the skin, as well as excessive formation of new small capillaries in the skin layer. Papules merge with each other, forming plaques. The formation of psoriatic plaques is associated with specific transformations and migration of keratinocytes from the deep layers to the outer ones during their differentiation. Horny scales are formed due to the accumulation of dead cells from deeper layers of the skin that have not had time to renew themselves.

The lower layer of the dermis with its blood, lymphatic vessels and nerves becomes inflamed and swollen. The inflammatory process is the result of the body’s immune response, which fights infection, promoting healing of wounds and injuries. In psoriasis, cells provoke the production of autoantibodies that affect their own cells of the skin and joints, so psoriasis is often referred to as an autoimmune chronic skin disease.

Unfortunately, no therapeutic approach provides a complete cure for psoriasis. Currently, the main goal of therapy is to reduce the severity of symptoms, and the use of modern means allows you to stabilize the condition and get long periods of remission. The choice of treatment methods and drugs depends on the severity of the condition, the age of the patient, the area of ​​the skin surface affected, the presence or absence of psoriatic arthritis, etc.

In psoriasis, there are three stages of the development of the disease: progressive, stationary and regressive. Therapy of various forms and stages of psoriasis includes the use of local and systemic drugs, and, if necessary, correction with excimer lasers, phototherapy, herbal medicine, PUVA therapy (high-intensity ultraviolet A irradiation), but combination therapy is most effective, primarily using biopharmaceutical drugs, i.e. medicinal substances of biological and biotechnological origin.

There are three treatment options for psoriasis :

I. Topical topical therapy (lotions, ointments, creams, shampoos).
II. Systemic drugs (tablets and injections).
III. Alternative treatments for psoriasis.

EXTERNAL THERAPY WITH LOCAL REMEDIES

External therapy of psoriasis plays a leading role, since among the forms of the disease, mild and moderate ones prevail, both in terms of the course and the prevalence of the skin process.

Keratolytics

A keratolytic is a substance that actively exfoliates dead skin cells from the surface of the skin. The drugs have been used since 1900 in the treatment of various forms of psoriasis. Keratoplastic and keratolytic (softening) agents do not have a pathogenic effect on the inflammatory psoriatic infiltrate, they only soften the thickened stratum corneum and facilitate exfoliation. For most patients, daily use of an emollient ointment or cream after a bath (shower) is an integral part of therapy. Typically, these formulations contain low concentrations of salicylic acid or higher concentrations of lactic acid from 5 to 12%). The components of these drugs, however, do not have a directed effect on inflammation in psoriasis. The drug is available in vials of 25 or 40 g.

Sulfur-salicylic ointment combination preparation for external use. When sulfur interacts with organic substances, sulfides and pentathionic acid are formed, which have an antimicrobial, antiparasitic effect. Sulfides, in addition, have keratoplastic properties. When using the drug in some cases, local reactions may occur in the form of itching, burning.

Anthralin ( Dithranol, Cygnoderm ) an external preparation for psoriasis, used as a cream (0.1-2%) and ointment (0.12%), has an irritant, keratolytic and keratoplastic effect when it slows down processes of mitosis and proliferation of epidermal cells, reducing the rate of protein synthesis.

An anti-psoriatic component from the legume Andira araroba has been identified as chrysarobin an easily oxidized chrysophanic acid reduction product. Synthetic substitute chrysarobin Anthralin was obtained in 1915, it has the ability to lead to remission of psoriasis, reproducing a component that is stable for a long time in the reduced active form, but quickly oxidizes in tissues. Factors limiting the use of the drug are irritant and coloring properties. Usually the drug is applied for 30-60 minutes. (short-term contact therapy) and then removed.

Therapeutic resins

Therapeutic resins are products of the destructive distillation of wood, coal or bitumen – they are very complex mixtures containing up to 10,000 components. Tar preparations appeared in medical practice in 1940.

Coal tar , which is a black liquid with a characteristic odor, has been used to treat psoriasis for about 100 years, now it is being replaced by more modern products containing vitamin D3. In an attempt to eliminate color and smell coal tar various hot distillation methods have been used. Tar alters keratinization, but its mechanism of action is poorly understood. The tool has antipruritic properties, has a weak antiseptic and photosensitizing effect. Purified resins are less phototoxic, but phototoxicity in psoriasis is directly related to the therapeutic effect. Coal tar is often combined with other drugs and used in PUVA therapy. The treatment has the following disadvantages: causes skin irritation and stains clothing. Patients using coal tar have a high risk of sunburn within 24 hours. after use.

To improve the condition of mild and moderate psoriasis allows the use of Coal tar and Anthralin a in combination. Unlike steroids, these agents do not cause skin thinning or drug tolerance.

Preservatives, dyes, flavors – Tbilisi Central District Hospital

Published: 17.08.2017, 10:33

A threat to your health – preservatives, dyes, flavors.

Everything that seems to be necessary, but very dangerous.

Agriculture is one of Russia’s four national priorities today. But even in this project, the leading role (the main priority) should be assigned to the cultivation of environmentally friendly non-GMO products. To preserve and improve health, we simply need such products, and in the West they are ready to pay big money for them. All conditions for the successful development of this area of ​​agriculture today are available. We have fertile land and money in the “jewel”, it’s only a matter of small things, the will of the country’s top leadership to develop and support this direction in every possible way.

Today we import more foodstuffs than we export, and this is the paradox of a gigantic country. Coming to the store, we are constantly confronted with products that contain various food additives E: preservatives, dyes, emulsifiers, etc. Studies have shown that a number of such substances pose a serious threat to our health. These additives are not needed to increase the health and nutritional value of foods, nor to improve health. They are used to enhance flavor, improve nutritional value, delay spoilage, extend shelf life, simplify preparation, and make foods more affordable. Studies have shown that a number of such substances, with constant use, depending on the individual influence, pose a serious threat to health.

Most artificial colors and flavors are derived from synthetic chemicals. Many of these products are believed to be toxic to the human body, and it is not known how they may affect future health. They are used due to their low cost compared to real, natural ingredients. In the last 30 years alone, the consumption of artificial dyes has increased 10 times. Several thousand tons of dyes of seven types from coal tar are consumed annually with products. Four out of seven dyes cause cancer in experimental animals.
