CLINICAL-TRIAL OF 2 OTITIS DRUGS (CONTAIN ING LINDANE AND FREE OF LINDANE) FOR THE TREATMENT OF OTITIS-EXTERNA PARASITARIA IN THE DOG AND CAT

Otitis externa parasitaria, caused by otodectes cynotis, occurs quite often in dogs and cats, though it happens more often in the cat. Two d ifferent medications - one with a lindane component and the other one lindane-free - were tested in 65 cases for their clinical efficacy. Th e study showed that the lindane containing otitis medication did not h ave a better effect (within the limited therapy period of 6 days) in t he treatment of otitis externa parasitaria. In the cat, both medicatio ns did not lead to complete recovery, but within the limited investiga tion period, a marked improvement was noticed. Also without lindane, o titis caused by otodectes can be treated with approximately equally go od results, if the treatment is maintained over a sufficient period of time. Evaluation of the lindane plasma concentration did not show a s ignificant increase in the lindane serum level in the major part of th e population after treatment with the lindane containing medication.
