    Abstract:
    The effect of chimotripsin on the level and duration of the ampicillin concentration increase in rats, as well as the effect of the enzyme on the in vitro antibiotic detection in the blood serum and organ homogenates of the animals was studied. It was found that rational combined use of ampicillin and chimotripsin required the enzyme administration not later than 1 hour before the antibiotic injection. Chimotripsin provided increased ampicillin levels in the blood serum and liver of the rats for at least 5 hours and in the kidneys and lungs for at least 4 hours. The enzyme present in the rats for 2 hours had no effect on determination of ampicillin activity in vitro in the presence of the blood serum and organ homogenates of the animals.
