Pharmacological properties of the drug Polcortolone
Triamcinolone (9α-fluoro-11β,16α, 17α, 21-tetrahydroxy-1,4-pregnadieno-3,20-dione) is a synthetic fluorinated corticosteroid, a prednisolone derivative with a pronounced anti-inflammatory effect. Triamcinolone at a dose of 4 mg is equivalent in anti-inflammatory activity to 4 mg methylprednisolone, 5 mg prednisolone, 0.75 mg dexamethasone, 0.6 mg betamethasone and 20 mg hydrocortisone. It has a weak mineralocorticoid effect. Triamcinolone inhibits the development of symptoms of inflammation without affecting the cause of its occurrence, inhibits the accumulation of macrophages, leukocytes and other cells at the site of inflammation. Inhibits phagocytosis, the release of lysosomal enzymes, as well as the synthesis and release of inflammatory mediators. Reduces the expansion and permeability of capillaries, which leads to a decrease in edema. The drug has an immunosuppressive effect, that is, it inhibits cellular immune reactions, reduces the number of T-lymphocytes, monocytes and acidophilic granulocytes. It may also inhibit the penetration of immune complexes through membranes and reduce the concentration of complement components and immunoglobulins. Triamcinolone inhibits the release of ACTH by the pituitary gland, which leads to a decrease in the synthesis of GCS in the adrenal cortex: after a single dose of triamcinolone in a dose of 60–100 mg, the suppression of adrenal function persists for 24–48 hours and returns to the original level after 30–40 days. Almost every patient taking the drug at a dose of 12–16 mg/day for more than 10 days may develop adrenal insufficiency. After long-term use of triamcinolone in high doses, adrenal function can recover within a year, and in some cases, its impairment is irreversible. Triamcinolone enhances protein catabolism, inhibits the synthesis and enhances the breakdown of proteins in lymphatic, connective, muscle tissue and skin, which can lead to their atrophy. The drug causes an increase in the concentration of glucose in the blood serum, affects fat metabolism, and increases the concentration of fatty acids in the blood plasma. With prolonged use, improper distribution of adipose tissue may occur. The drug slows down the synthesis of bone tissue, reduces the concentration of calcium in the blood plasma, can inhibit bone growth in children and adolescents and lead to the development of osteoporosis at any age. Enhances the effect of endo- and exogenous catecholamines. The bioavailability of triamcinolone after oral administration is 20–30%. The effect appears after 1-2 hours and lasts for 6-8 hours. The half-life of triamcinolone from blood serum is ≥2-5 hours, from tissues - 18-36 hours. The period of action is 54 hours, food inhibits the absorption of triamcinolone in the initial phase , but does not affect the overall bioavailability of the drug. About 40% of triamcinolone is bound to serum proteins (mainly globulins). The volume of distribution of the free fraction of the drug is 0.6–2 dm3/kg body weight. The drug is metabolized in the liver, and to a lesser extent in the kidneys. It is excreted from the body mainly in the urine in the form of inactive metabolites, ≤15% is unchanged triamcinolone. Three metabolites of triamcinolone acetate have been identified: 6β-hydroxytriamcinolone acetate, 21-carboxy-6β-hydroxytriamcinolone acetate, and 21-carboxytriamcinolone acetate. Triamcinolone penetrates the placental barrier and into breast milk.

Reviews
Polcortolon has mixed reviews. Some patients have a negative attitude towards the drug, as it provokes a large list of adverse reactions. That not everything is suitable even when taken correctly. Nevertheless, it is quite strong and can eliminate the unpleasant symptoms of various diseases. Doctors recommend undergoing an examination before starting treatment in order to minimize the risk of adverse reactions.
Since the drug is hormonal, it often leads to weight gain in females, which is why they do not like this drug. But in the presence of severe pathologies that cannot be treated with other medications, they are ready to use Polcortolone, despite the huge number of negative phenomena.
The aerosol, when used correctly and for a short course of therapy, is usually well tolerated. Moreover, it also contains an antibacterial substance. This significantly improves the results of therapy. Skin manifestations can be eliminated after just two weeks of using the spray. But it is recommended to use it in minimal quantities and for a short time.
The drug has many contraindications and adverse reactions, but it is widely used in medicine, as it has proven its high effectiveness.
Special instructions for the use of Polcortolon
Sudden discontinuation may cause symptoms of adrenal insufficiency, so the dose of triamcinolone should be reduced gradually. Patients taking triamcinolone are not recommended to be vaccinated with live viral vaccines. The use of an inactivated viral or bacterial vaccine may not be accompanied by the expected increase in antibody titer. In case of active tuberculosis, the use of triamcinolone should be limited and carried out simultaneously with antibacterial therapy. Patients with latent tuberculosis or a positive tuberculin test should be under medical supervision due to the possibility of exacerbation of the tuberculosis process, and with long-term use of the drug, take prophylactic antibacterial drugs. Sudden cessation of use after long-term use can cause GCS withdrawal syndrome , manifested by fever, myalgia, arthralgia, and poor health. These symptoms can occur even in the absence of adrenal insufficiency. Triamcinolone may mask symptoms of infection by reducing resistance to infection and the ability to contain the lesion. In persons arriving from tropical countries, infection with dysenteric amoeba should be excluded before using the drug. Triamcinolone in high doses can cause an increase in blood pressure, water and sodium retention, and increase the excretion of potassium and calcium. In people with thyroid deficiency and liver cirrhosis, triamcinolone is more active, so the drug should be used in lower doses. For herpetic eye infections, triamcinolone is used with caution due to the risk of corneal perforation. Long-term use of the drug can cause clouding of the lens, glaucoma with damage to the optic nerve, and also increase the risk of secondary fungal or viral eye infections. With prolonged use, the drug should be prescribed in the minimum effective doses. Use triamcinolone with caution in combination with acetylsalicylic acid for hypoprothrombinemia. Triamcinolone should be used only for reasonable indications and with great caution in cases of ulcerative colitis, intestinal diverticula, peptic ulcers of the stomach or duodenum, renal failure, hypertension, osteoporosis, muscle fatigue, diabetes, hypofunction of the liver, glaucoma, candidiasis or viral infection. Animal studies have established a risk of teratogenicity. Polcortolone used during pregnancy can cause placental insufficiency, fetal adrenal insufficiency, low birth weight or fetal death. The use of GCS by women of reproductive age and pregnant women is permissible only for health reasons or in cases where the benefit of the drug outweighs the potential threat to the fetus. Polcortolone is excreted into breast milk and causes undesirable effects in the baby. In newborns and infants whose mothers took triamcinolone for a long time or in high doses, the drug may cause inhibition of growth and development. Breastfeeding should be stopped while taking triamcinolone.

Interactions of the drug Polcortolone
The combination of triamcinolone with the following drugs causes: NSAIDs, alcohol - an increased risk of ulcers and gastrointestinal bleeding. Amphotericin B, carbonic anhydrase inhibitors - hypokalemia, myocardial hypertrophy, congestive circulatory failure. Paracetamol - hypernatremia, edema, increased calcium excretion, increased hepatotoxicity of paracetamol. Anabolic steroids, androgens - swelling, rash. Anticholinergic drugs (mainly atropine) - increase intraocular pressure. Anticoagulants, coumarin derivatives, indadione, heparin, streptokinase, urokinase - decreased, in some patients - increased effect; increased risk of ulceration and gastrointestinal bleeding. Tricyclic antidepressants - increased mental disorders. Oral antidiabetic drugs, insulin - weakening of the antidiabetic effect. Triamcinolone alters thyroid function, so it may be necessary to change the dose or stop taking anti-thyroid medications or thyroid hormones. Oral contraceptives containing estrogens enhance the effect of triamcinolone. Digitalis glycosides - tachycardia and increased toxicity of glycosides. Diuretics - weakening of the effect of diuretics, hypokalemia. Folic acid - increasing the need for this product. Immunosuppressive drugs - increased risk of infection, development of lymphangiomas and other lymphoproliferative diseases. Isoniazid - a decrease in the concentration of isoniazid in the blood serum, mainly in individuals with rapid acetylation, dose adjustment may be necessary. Mexiletine - accelerated metabolism of mexiletine and a decrease in its concentration in the blood serum. Sodium salts - edema, increased blood pressure; You may need to limit your intake of high sodium medications and the amount of sodium in your diet; Vaccines containing live viruses - during the use of GCS in immunosuppressive doses, the development of viral diseases and a decrease in the effectiveness of vaccination are possible. Other vaccines increase the risk of developing neurological complications, as well as reduce the formation of antibodies.
