Safiston Pharmacodynamics
Safiston is a combination drug, the action of which is determined by the components included in 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. Its lack of effect on prostaglandin (PG) synthesis in peripheral tissues explains its lack of negative effect on water-salt metabolism (sodium and water retention) and gastrointestinal mucosa.
Propiphenazone is a pyrazolone derivative. Its mechanism of action is by inhibiting COX, which is involved in the formation of prostaglandins from arachidonic acid.
Caffeine increases reflex excitability of spinal cord, excites respiratory and vasomotor centers, dilates blood vessels of skeletal muscles, brain, heart, kidneys, reduces platelet aggregation; reduces drowsiness, feeling of fatigue. In this combination, caffeine in a low dose has almost no stimulating effect on the central nervous system, but it helps to regulate the tone of the brain vessels, reduces drowsiness, increases the analgesic effect of other components of the drug.
Indications
It is used for treatment of pain syndrome of low and medium intensity of different genesis: headache, migraine, toothache, arthralgia, myalgia, algodysmenorrhea and as antipyretic in febrile states caused by inflammatory diseases (acute respiratory infections, including influenza and others).
