Pharmacological action

Pharmacotherapeutic group:

Combined analgesic (NSAIDs + non-narcotic analgesics + psychostimulant).

ATX code:

N02BE51

Pharmacological properties of

Pharmacodynamics

Safiston is a combination drug, whose action is determined by the components that make up its composition. The combination of the three components of the drug leads to a mutual strengthening of their pharmacological action. Paracetamol and propiphenazone have analgesic and antipyretic effects.

Paracetamol is a non-narcotic analgesic. It blocks cyclooxygenase (COX) only in the central nervous system (CNS), affecting the centers of pain and thermoregulation (in inflamed tissues, cellular peroxidases neutralize the effect of paracetamol on COX), which explains the almost complete absence of anti-inflammatory effect.

The absence of an effect on the synthesis of prostaglandins (PG) in peripheral tissues leads to the absence of a negative effect on the water-salt metabolism (sodium and water retention) and the gastrointestinal mucosa.

Propiphenazone is a pyrazolone derivative. The mechanism of action is carried out by inhibiting COX, which is involved in the formation of prostaglandins from arachidonic acid.

Caffeine increases the reflex excitability of the spinal cord, stimulates the respiratory and vasomotor centers, dilates the blood vessels of the skeletal muscles, brain, heart, kidneys, reduces platelet aggregation, reduces drowsiness, and a feeling of tiredness.

In this combination, a small dose of caffeine practically does not have a stimulating effect on the central nervous system, but it helps to regulate the tone of the brain vessels, reduces drowsiness, and enhances the analgesic effect of other components of the drug.

Pharmacokinetics

Paracetamol

Absorption - high, binding to plasma proteins - 15%, time to reach maximum plasma concentration (TCmax) - 20-30 min. Penetrates through the blood-brain barrier (BBB). Less than 1% of the dose taken by the nursing mother passes into breast milk.

Therapeutic effective plasma concentration of paracetamol is achieved when administered at a dose of 10-15 mg / kg.

Metabolized in the liver: 80% undergoes a conjugation reaction with glucuronic and sulfuric acids to form inactive metabolites 17% undergoes hydroxylation to form inactive metabolites that conjugate with glutathione and form inactive metabolites.

With a lack of glutadione, these metabolites can block the hepatocyte enzyme systems and cause their necrosis. The elimination half-life is 2-3 hours. In elderly patients, paracetamol clearance decreases and the elimination half-life increases. It is excreted by the kidneys unchanged 3%.

Propiphenazone

The maximum concentration of propiphenazone in plasma is reached after 30 minutes. Metabolized in the liver. The half-life is 1-1.5 hours. The combination with paracetamol increases its elimination time by 40%, which plays a significant role, as allows you to reduce the number of doses of the drug during the day. It is excreted by the kidneys.

Caffeine

Time to reach maximum concentration - 1 h half-life - 3.5 h 65-80% of caffeine is excreted by the kidneys mainly in the form of 1-methylxatin, 1-methyl uric acid and acetylated uracil derivatives, a small amount is converted to theophylline and theobromine.

Drug Interactions

The effectiveness of the drug may decrease with the simultaneous use of cholistiramine, anticholinergics, antidepressants, alkaline substances.

With the simultaneous use of Safiston with barbiturates, anticonvulsants, ethanol, the hepatotoxic effect significantly increases.

Metoclopramide accelerates the absorption of paracetamol. Under the influence of paracetamol, the half-life of chlorofenicol increases by 5 times. The simultaneous use of paracetamol in high doses increases the effect of anticoagulants. Myelotoxic drugs increase the hematotoxicity of paracetamol.

Caffeine accelerates the absorption of ergotamine reduces the absorption of calcium preparations reduces the effect of narcotic and hypnotics, increases the excretion of lithium preparations accelerates absorption and enhances the action of cardiac glycosides, increases their toxicity.

The simultaneous use of caffeine with beta-blockers can lead to mutual suppression of therapeutic effects, with beta-adrenergic agonists to additional stimulation of the central nervous system and other toxic effects.

Caffeine may decrease clearance of theophylline, and possibly other xanthines, increasing the potential for additive pharmacodynamic and other toxic effects. Monoamine oxidase inhibitors, furazolidone, procarbazine, selegiline and large doses of caffeine can cause the development of dangerous cardiac arrhythmias or a marked increase in blood pressure. Nicotine increases the rate of excretion of caffeine. Caffeine is an antagonist of adenosine.

Propiphenazole can enhance the effect of oral hypolipidemic drugs, sulfa drugs, anticoagulants, the ulcerogenic effect of glucocorticosteroids, and reduces the effectiveness of potassium-sparing diuretics.
