Cephalexin capsules are indicated for the treatment of the following infections when caused by susceptible strains of the designated microorganisms: Respiratory tract infections caused by Streptococcus pneumoniae and Streptococcus pyogenes (Penicillin is the usual drug of choice in the treatment and prevention of streptococcal infections, including the prophylaxis of rheumatic fever. Cephalexin is generally effective in the eradication of streptococci from the nasopharynx; however, substantial data establishing the efficacy of cephalexin in the subsequent prevention of rheumatic fever are not available at present.) Otitis media due to Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus, Streptococcus pyogenes, and Moraxella catarrhalis Skin and skin structure infections caused by Staphylococcus aureus and/or Streptococcus pyogenes Bone infections caused by Staphylococcus aureus and/or Proteus mirabilis Genitourinary tract infections, including acute prostatitis, caused by Escherichia c

Abbreviated New Drug Application
CEPHALEXIN- CEPHALEXIN CAPSULE LAKE ERIE MEDICAL DBA QUALITY CARE PRODUCTS LLC ---------- CEPHALEXIN CAPSULES, USP To reduce the development of drug-resistant bacteria and maintain the effectiveness of cephalexin and other antibacterial drugs, cephalexin should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. DESCRIPTION Cephalexin, USP is a semisynthetic cephalosporin antibiotic intended for oral administration. It is 7-(D- α-Amino-α-phenylacetamido)-3-methyl-3-cephem-4-carboxylic acid monohydrate. Cephalexin has the molecular formula C H N O S•H O and the molecular weight is 365.41. Cephalexin has the following structural formula: The nucleus of cephalexin is related to that of other cephalosporin antibiotics. The compound is a zwitterion; i.e., the molecule contains both a basic and an acidic group. The isoelectric point of cephalexin in water is approximately 4.5 to 5. The crystalline form of cephalexin which is available is a monohydrate. It is a white crystalline solid having a bitter taste. Solubility in water is low at room temperature; 1 or 2 mg/mL may be dissolved readily, but higher concentrations are obtained with increasing difficulty. The cephalosporins differ from penicillins in the structure of the bicyclic ring system. Cephalexin has a _D_-phenylglycyl group as substituent at the 7-amino position and an unsubstituted methyl group at the 3- position. Each capsule contains cephalexin monohydrate equivalent to 250 mg or 500 mg of cephalexin. The capsules also contain anhydrous lactose, gelatin, magnesium stearate, talc and titanium dioxide. The capsules are imprinted with edible ink containing black iron oxide. CLINICAL PHARMACOLOGY HUMAN PHARMACOLOGY Cephalexin is acid stable and may be given without regard to meals. It is rapidly absorbed after oral administration. Following doses of 250 mg, 500 mg, and 1 g, average peak serum levels of approximately 9, 18, and 32 µg/mL respectively were obtained at 1 hour. Measurable levels were 16 1 전체 문서 읽기
