Clinical, cardiovascular and respiratory effects of R8110 in premedicated dogs.
The clinical, cardiovascular and respiratory effects after i.v. administration of R8110, a fluoro analogue of etomidate (Fig. 1), were studied in pre-medicated dogs. The clinical observations were made at doses of 3 and 4 mg/kg body weight (BW) injected slowly i.v., whereas cardiovascular and respiratory studies were carried out at a dose rate of 3 mg/kg R8110 i.v. Induction and recovery were smooth and no significant side-effects were observed. The cardiovascular system was slightly influenced, but respiration was hardly affected. The effect of pre-medication on respiration and the cardiovascular system was hardly potentiated by R8110. Although there were significant changes in cardiovascular and biochemical parameters, all values remained within physiological limits. R8110 appeared to be a safe and reliable induction agent.
