Effect of lidocaine on the absorption, disposition and tolerance of intramuscularly administered cefoxitin.

The use of lidocaine HCL solution at concentrations of 0.5 and 1.0% to reconstitute sodium cefoxitin relieves the pain associated with intramuscular injections of the antibiotic.

Comparative clinical pharmacology of intravenous cefoxitin and cephalothin.

Intravenous doses of 0.5, 1, and 2 g cephalothin and cefoxitin, a semi-synthetic cephamycin antibiotic highly resistant to bacterial cephalosporinase, were infused over a period of 3 minutes into 18 normal adult males by a randomized, crossover design. Serum and urine data on cefoxitin best fit a two-compartment open model.
