Contraindications
Documented hypersensitivity to drug, penicillin, related compounds, or milk protein sodium caseinate; carnitine deficiency or inborn errors of metabolism that may result in clinically significant carnitine deficiency
Cautions
May cause diarrhea, nausea, and vaginal moniliasis (yeast infection); pseudomembranous colitis may occur; clinical manifestations of carnitine deficiency may occur with prolonged use; prolonged use may result in emergence and overgrowth of resistant organisms; caution in breastfeeding
Pregnancy and lactation
Pregnancy category: B
Lactation: excretion in milk unknown; 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 of Spectracef (cefditoren)
Half-Life: 1.2-2 hr
Peak Plasma Time: 1.5-3 hr
Excretion: urine
Mechanism of action
Semi-synthetic cephalosporin administered as prodrug. Hydrolyzed by esterases during absorption and distributed in circulating blood as active cefditoren. Bactericidal activity results from inhibition of cell wall synthesis via affinity for penicillin-binding proteins. No dose adjustment necessary for mild renal impairment (CrCl 50-80 mgL/min/1.73 m2) or mild to moderate hepatic impairment.
