BURROUGHS WELLCOME NIX ANTI-LICE CREAM RINSE TREATMENT
Executive Summary
BURROUGHS WELLCOME NIX ANTI-LICE CREAM RINSE TREATMENT will be available to pharmacies by June, the company said. Burroughs Wellcome is pricing the Rx creme rinse to whslrs. at "about $6.00" for a two-ounce bottle packaged with a comb. Nix (permethrin) was approved by FDA on March 31 as a 1B drug (new molecular entity representing a modest therapeutic gain), after a review period of just over a year. Burroughs Wellcome filed the NDA in February 1985. The product is indicated for single-application treatment of infestation with the head louse and its eggs. "Retreatment for recurrences is required in less than 1% of patients since the ovicidal activity may be supplemented by residual persistence in the hair" the labeling notes. "Nix is the first head lice treatment to kill both lice and nits (eggs) and to provide protection from reinfestation for up to 14 days with a single application," the company said in a recent press release. The firm added that the product is the first pyrethroid to be formulated for human use.
