Sulacillin pharmacokinetics was studied in experiments on 20 rabbits.
The drug dose was equivalent to 1.5 g for humans administered both alo
ne and in combination with bacterial protease catalytin injected intra
muscularly. Experiments showed that sulacillin should be injected with
an interval of not more than 8 h and the its circulation in the blood
is prolonged by catalytin.
