Pregnancy category: B
Lactation: Drug enters breast milk; use with caution
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Binds to penicillin-binding proteins and inhibits final transpeptidation step of peptidoglycan synthesis, resulting in cell-wall death; resists degradation by beta-lactamase; proper dosing and appropriate route of administration are determined by condition of patient, severity of infection, and susceptibility of microorganism
Absorption
Peak plasma time: IM, 30 min
Distribution
Distribution: widely distributed to body tissues and fluids, including aqueous humor, ascitic and prostatic fluids, bone, penetrates CSF when meninges inflamed
