title: Toxicological studies on a new macrolide antibiotic, midecamycin acetate (miokamycin). Part II-1. Subacute toxicity in rats.
abstract: Miokamycin (MOM) is a derivative of midecamycin, a macrolide antibiotic isolated from a culture broth of Streptomyces mycarofaciens. The objective of this study was to determine the subacute toxicity in male and female rats (Wistar, SPF, 5-week-old) after repeated oral administration of MOM, non-crystalline solid, for 5 weeks at selected dosage levels of 1,000, 2,000 and 4,000 mg/kg/day. It is concluded that the maximum non-toxic dosage level of MOM, non-crystalline solid, was 1,000 mg/kg/day but without specific toxic effects with rats when it was orally administered once daily for 5 weeks.
