Serum antibacterial activity after oral suspensions and capsules of triacetyloleandomycin and erythromycin estolate.

Comparison of serum antibacterial activity against a beta-hemolytic streptococcus and a penicillin-resistant staphylococcus was made in a cross-over study in volunteers after ingestion of oral suspensions and capsules of triacetyloleandomycin and erythromycin estolate. Oral suspensions yielded earlier peak titers, but ultimate peak titers and duration of activity were similar to those observed after ingestion of capsules. Antibacterial activity of serum against both organisms was consistently greater with both erythromycin estolate preparations than with the triacetyloleandomycin preparations. These in vitro data were comparable to observations made previously in monkeys infected with the same organisms, although comparative clinical efficacy in monkeys did not reflect these implied therapeutic differences.

Comparison of cephalexin, penicillin V, and ampicillin in streptococcal infections in monkeys.

Intravenous inoculation of a group A hemolytic streptococcus caused lethal infections in all of 11 untreated monkeys. Daily intragastric administration of either 25 or 50 mg per kg per day, given in two equal morning and afternoon doses, yielded similar results in monkeys treated with cephalexin, penicillin V, and ampicillin; all eight monkeys in each therapy group survived. At dose levels of 12.5 mg per kg per day, six of eight, four of eight, and one of eight receiving cephalexin, penicillin V, and ampicillin, respectively, died. The differences observed at the lower dose level between cephalexin and ampicillin could be attributed, in part, to differences in the minimal inhibitory concentrations (MIC) of cephalexin (MIC = 0.24 mug/ml) and ampicillin (MIC = 0.01 mug/ml). The differences in results between penicillin V, which had the same MIC as ampicillin, could perhaps be attributed, in part, to shorter duration of antibacterial activity and higher protein binding of penicillin V. These studies support previous observations that cephalexin at 25 to 50 mg/kg doses is effective in severe streptococcal sepsis in monkeys.

Therapy of staphylococcal infections in monkeys. IV. Further comparison of triacetyloleandomycin and erythromycins.

Intravenous inoculation of a penicillin-resistant, phage type 80/81 staphylococcus caused lethal infection in 8 of 15 untreated monkeys. Daily intragastric administration of 50 mg/kg of triacetyloleandomycin, erythromycin estolate, and erythromycin ethylsuccinate was followed by mortalities of 0 of 16, 3 of 16, and 3 of 10, respectively. At dose levels of 25 and 12.5 mg/kg, none of 7 and 4 of 7 receiving triacetyloleandomycin and erythromycin estolate, respectively, died, as compared to 3 of 4 deaths in controls. In vitro sensitivity data and serum antibacterial levels would suggest that triacetyloleandomycin would be the least effective therapeutically. However, this prediction was not fulfilled in these studies of experimental infections in monkeys wherein triacetyloleandomycin was a very effective antimicrobial agent.
