Otoprotective Effect of Cortexin, Cogitum, and Elkar Administered Simultaneously with Netromycin in the Experiment

We studied possible otoprotective effect of drugs widely used for the correction of perinatal hypoxic brain damage in premature infants. The experiments were carried out on immature rabbits with an immature hearing organ. The auditory function was assessed by DPOAE and ABR methods in intact animals and rabbits treated with therapeutic doses of netromycin alone or in combination with the drugs that normalize metabolic processes in the brain (Cortexin, Cogitum, Elkar, vitamin B2, ATP, and cocarboxylase). It was found that the administered drugs produced an otoprotective effect and reduced the severity, but did not eliminate the ototoxic effect.
