pharmachologic effect

Pharmacodynamics

Tetrizoline is a sympathomimetic agent that belongs to the group of imidazoline decongestants. It directly stimulates the alpha-adrenergic receptors of the sympathetic nervous system with little or no influence from the beta-adrenergic receptors. When applied topically on the conjunctival mucosa, the preparation has a temporary vasoconstrictor effect on small blood vessels, thereby reducing vasodilation and conjunctival edema.

Pharmacokinetics

In a study involving 10 healthy volunteers after therapeutic ocular administration, tetrizoline was shown in blood serum and urine. The serum half-life of tetrizoline was approximately 6:00. Systemic absorption in patients varied, with maximum serum concentrations ranging from 0.068 to 0.380 ng / ml. After 24 hours, all patients were found to have tetrizoline in the urine.
