Pharmacological action

Prednisone - glucocorticoid, anti-allergic, anti-inflammatory.

Pharmacodynamics

Synthetic corticosteroids with a pronounced anti-inflammatory effect (action of 5 mg of prednisolone is equivalent to 4 mg of methylprednisolone, 4 mg of triamcinolone, 0.75 mg of dexamethasone, 0.6 mg of betamethasone, 20 mg of hydrocortisone). Its mineralocorticoid effect accounts for about 60% of the activity of hydrocortisone. It inhibits the development of symptoms of inflammation. Inhibits the accumulation of macrophages, white blood cells and other cells in the area of ​​inflammation. It inhibits phagocytosis, the release of lysosomal enzymes, as well as the synthesis and release of inflammatory mediators. Causes a decrease in capillary permeability, inhibition of white blood cell migration. It enhances the synthesis of lipomodulin, an phospholipase A2 inhibitor that releases arachidonic acid from phospholipid membranes, while inhibiting its synthesis.

Immunosuppressive effect. The mechanism is not fully understood. Prednisolone is known to reduce the number of T-lymphocytes, monocytes and acidophilic granulocytes. Reduces the binding of immunoglobulins to receptors on the cell surface and inhibits the synthesis or release of interleukins by reducing the blastogenesis of T-lymphocytes and reducing the early immunological response. It inhibits the penetration of immunological complexes through membranes and reduces the concentration of components, complement and immunoglobulins.

Effect on water-electrolyte balance. It acts on the distal part of the renal tubules, enhancing the reverse absorption of sodium and water, as well as increasing the excretion of potassium and hydrogen ions.

Other effects. It inhibits the secretion of ACTH by the pituitary gland, which leads to a decrease in the production of corticosteroids and androgens by the adrenal cortex. After prolonged use of large doses, adrenal function can recover within about a year, and in some patients there is a persistent suppression of their function.

Enhances protein catabolism and induces enzymes involved in amino acid metabolism. It inhibits the synthesis and enhances protein catabolism in the lymphatic, connective, muscle and skin tissue. With prolonged use, atrophy of these tissues may develop.

Increases blood glucose concentration by inducing gluconeogenesis enzymes in the liver, stimulating protein catabolism (which increases the number of amino acids for gluconeogenesis) and reducing glucose uptake in peripheral tissues. This leads to the accumulation of glycogen in the liver, an increase in the concentration of glucose in the blood and an increase in insulin resistance. Enhances lipolysis and mobilizes fatty acids from adipose tissue, which increases the concentration of fatty acids in serum. With prolonged treatment, redistribution of adipose tissue is possible. It inhibits the formation of bone tissue and enhances its resorption, reducing the concentration of calcium in the blood serum, which leads to secondary hyperfunction of the parathyroid glands, simultaneous stimulation of osteoclasts and inhibition of osteoblasts. These effects, together with a secondary decrease in the amount of protein components as a result of protein catabolism, can lead to inhibition of bone growth in children and adolescents and the development of osteoporosis in patients of all ages.

Enhances the action of endo- and exogenous catecholamines.

Pharmacokinetics

After oral administration, bioavailability is 70–90%. Serum Cmax is reached within 1–2 hours after administration. Food slows down the absorption of prednisone in the initial phase, but does not affect the overall bioavailability of the drug. Binding to serum proteins is 90–95%. It is metabolized mainly in the liver, to a lesser extent - in the kidneys. It is excreted in the urine in the form of inactive metabolites, in a small amount - unchanged. T1 / 2 from blood serum is 2.1–3.5 hours, from tissues - 18–36 hours. The duration of the drug is 1.25-1.5 days. Passes through the placental barrier, less than 1% of the dose passes into breast milk.

Drug Interaction

Cardiac Glycosides: increased risk of cardiac arrhythmias and glycoside toxicity associated with hypokalemia.

Barbiturates, antiepileptic drugs (phenytoin, carbamazepine), rifampicin, glutethimide accelerate the metabolism of GCS (by induction of microsomal enzymes), attenuate their action.

Antihistamines weaken the action of prednisolone.

Paracetamol: hypernatremia, peripheral edema, increased calcium excretion, risk of hypocalcemia and osteoporosis. Increased risk of hepatotoxicity of paracetamol.

Anabolic steroids, androgens: increase the risk of developing peripheral edema, use acne with caution, especially in the case of liver and heart disease.

Oral contraceptives containing estrogens: increase in concentration of globulins binding glucocorticosteroids in serum, slowing of metabolism, increase of T1 / 2, increase of action of prednisolone.

Cholinergic drugs (mainly atropine) - increase in intraocular pressure.

Anticoagulants (coumarin derivatives, indandion, heparin), streptokinase, urokinase: reduction, and in some patients the increase in the efficacy of the dose should be determined on the basis of PV increasing the risk of ulceration and bleeding from the gastrointestinal tract.

Tricyclic antidepressants can increase the mental disorders associated with prednisolone intake. They should not be prescribed to treat these disorders.

Oral antidiabetic drugs, insulin: hypoglycemic action, increase in blood glucose concentration. Dose adjustment for anti-diabetic drugs is possible.
