Documented Uses

• Antibiotic substance produced along with penicillin N by a Cepahlosporium sp. cultivated from sea water near a sewage outlet on the coast of Sardinia.
• 7-AMINOCEPHALOSPORANIC ACID, PREPD FROM NATURAL ANTIBIOTIC CEPHALOSPORIN C BY EITHER PROTONCATALYZED OR ENZYMATIC HYDROLYSIS, IS ACYLATED WITH 2-PHENYLGLYCINE IN APPROPRIATE DEHYDRATING ENVIRONMENT. /DIHYDRATE/
• For treatment of severe infections caused by susceptible bacteria.
• ...BECAUSE CEPHALOGLYCIN IS CONCENTRATED IN URINE, IT MAY BE EFFECTIVE IN TREATMENT OF URINARY TRACT INFECTIONS... /DIHYDRATE/
• MOST OF CEPHALOGLYCIN...IS EXCRETED IN URINE AS DEACETYLCEPHALOGLYCIN, AN ANTIMICROBIALLY ACTIVE METABOLITE. URINARY CONCN OF METABOLITE AVG 350 UG/ML OVER 8-HR PERIOD FOLLOWING ADMIN OF 500 MG OF CEPHALOGLYCIN; THIS IS SUFFICIENT TO INHIBIT MOST STRAINS OF E COLI, MIRABILIS, & KLEBSIELLA-ENTEROBACTER (AEROBACTER) GROUP.
