Pharmacological properties
Pharmacodynamics
Otolorin is a combined preparation for topical use in otorhinolaryngology, has an antiseptic, disinfectant and moderately analgesic effect.
The clinical effect of the drug is due to the following properties of its active ingredients:
- boric acid: has an antiseptic and fungistatic effect, in relation to granulation tissues has a weak irritating effect;
- procaine: a local anesthetic with moderate potency and a wide therapeutic range. It is a weak base, which allows you to block sodium channels and prevent the generation of impulses in the endings of sensory nerves and their conduction along nerve fibers. In the membranes of nerve cells, it modifies the action potential without exerting a pronounced effect on the resting potential. Helps suppress the conduction of impulses of various modality, including pain.
Pharmacokinetics
Boric acid actively penetrates through mucous membranes and damaged tissues, especially in young children. It is displayed slowly. About 50% is excreted through the kidneys during the first 12 hours, the rest is excreted during the next 120 hours or more. Penetrating into organs and tissues, it can accumulate in them with repeated injections.
Procaine undergoes complete systemic absorption, which is particularly dependent on vascularization at the site of administration and blood flow rate, as well as on the site, route of administration and the final dose (amount and concentration). As a result of rapid hydrolysis by plasma and liver esterases, two main pharmacologically active metabolites are formed - diethylaminoethanol, which has a moderate vasodilating effect, and para-aminobenzoic acid (PABA). PABA is a competitive antagonist of sulfanilamide chemotherapeutic agents that can weaken their antimicrobial effects. The half-life of procaine is 0.7 minutes. It is excreted mainly through the kidneys in the form of metabolites, no more than 2% - unchanged.
