Documented Uses

  • 7-AMINOCEPHALOSPORANIC ACID, PREPD FROM NATURAL ANTIBIOTIC CEPHALOSPORIN C ... IS ACYLATED ... IN APPROPRIATE DEHYDROCHLORINATING ENVIRONMENT, & RESULTING CEPHAPIRIN (ACID) IS CONVERTED INTO ITS SODIUM SALT BY INTERACTION WITH SODIUM 2-ETHYLHEXANOATE IN SUITABLE ORG SOLVENT. /CEPHARIRIN SODIUM/
  • For treatment of infections caused by susceptible bacteria.
  • Cephalosporins are still useful as alternatives to penicillins for a variety of infections in patients who can't tolerate penicillins. These include streptococcal and staphylococcal infections.
  • BACTERIA SUSCEPTIBLE TO CEPHALOTHIN /BOTH GRAM POSITIVE & GRAM-NEGATIVE MICROORGANISMS/ ARE SENSITIVE OVER APPROX SAME RANGE OF CONCN TO ... CEPHAPIRIN. ... CEPHAPIRIN IS SOMEWHAT MORE INHIBITORY THAN CEPHALOTHIN FOR GROUP-A STREP PYOGENES & PNEUMOCOCCUS.
  • CEPHAPIRIN IS ONE OF NEWEST SEMISYNTHETIC CEPHALOSPORINS. ... LIKE OTHER CEPHALOSPORINS, CEPHAPIRIN SHOULD BE RESERVED FOR THOSE INSTANCES IN WHICH ORGANISM IS SENSITIVE TO IT & PATIENT IS HYPERSENSITIVE TO PENICILLIN.
