The role of the pharmaceutical animal health industry in post-marketing surveillance of resistance.

The pharmaceutical animal health industry must be committed to the total life cycle of products, i.e. during both the pre- and post-marketing period. Support of antibacterial agents during the postmarketing period is not restricted to maintaining a well-established distribution and promotion system. Care has to be taken continuously to maintain and/or improve the quality, safety (for user, target animal and environment) and clinical efficacy. The pharmaceutical industry contributes to this by: 1. Introducing antibacterials in different animal species for the most effective disease condition only and by ensuring the veterinary profession is informed about relevant findings on: a. the mechanism of action; b. pharmacodynamic properties; c. pharmacokinetic properties (plasma, target tissue); d. clinical efficacy data and in vitro sensitivity data; e. valid species-specific MIC breakpoints; f. precise dose and treatment regime. 2. Updating on a regular basis on: a. new findings on the mechanism of action (in vitro and in vivo); b. the optimal use program in the light of changes in animal husbandry, farm management and epidemiology on national and international level; c. adjustment of species-specific MIC breakpoints when necessary. 3. Providing continuous information in collaboration with animal health laboratories about: a. clinical field surveillance for efficacy (national, international); b. in vitro sensitivity/resistance surveillance (national, international); c. use of in vitro data to support prediction of in vivo efficacy. Surveillance of resistance, in vitro, is therefore part of a package of information needed on a routine basis by the pharmaceutical industry to allow the best possible use of antibacterials and to minimize induction of resistance.(ABSTRACT TRUNCATED AT 250 WORDS)
