Cephalothin is a first generation, semisynthetic analogue of natural cephalosporin antibiotic. The in-vitro bactericidal action of Cephalothin results from inhibition of cell-wall synthesis. In general, Cephalothin has higher activity against Gram positive than Gram negative organisms. Cephalothin is primarily indicated in conditions like bone and joint infection, genitourinary tract infections, respiratory tract infections, soft tissue and skin infections and others. The severe or irreversible adverse effects of Cephalothin, which give rise to further complications, include nephrotoxicity, hemolytic anemia. Cephalothin produces potentially life-threatening effects, which include anaphylaxis, serum sickness syndrome. The symptomatic adverse reactions produced by Cephalothin are: rashes, urticaria, allergic reactions, thrombophlebitis, pain at injection site. Co-administration of diuretics, such as furanthril, ethacrynic acid and nephrotoxic antibiotics may increase the risk of renal damage. Reciprocal inactivation could be observed during in vitro mixing of Cephalothin with aminoglycosides.

Sample Use Guides

In Vivo Use Guide

The usual dosage range is 500 mg to 1 g of cefalotin every four to six hours. In severe infections, this may be increased by giving the injections every four hours or, when the desired response is not obtained, by raising the dose to 1 g. In lifethreatening infections, in patients with normal renal function, doses up to 2 g every four hours may be required.

Route of Administration: Other

In Vitro Use Guide

Cephalothin was very effective in vitro against staphylococcal isolates, with an MIC90 of 0.12 ug/mL. The cephalothin MIC90 for E.coli was 64 ug/mL.
