Preclinical Research & Development Current drugs for obesity treatment have limited efficacy and considerable adverse effects. Combination of drugs with complementary mechanisms of action at lower doses may produce a greater efficacy with a better safety profile. This study was designed to assess the anorectic effect and safety of a diethylpropion + topiramate mixture in rats. The anorectic effect of drugs was measured using a sweetened milk consumption model, and the corresponding interaction was determined by isobolographic analysis, interaction index and confidence intervals. Additionally, blood pressure was measured using a sphygmomanometer in the rat tail. Diethylpropion and topiramate alone or in combination increased the anorectic effect in a dose-dependent fashion in either nondeprived or 12 hr food-deprived rats. All theoretical ED values of diethylpropion + topiramate combinations at 1:1, 1:3, and 3:1 dose ratios were significantly higher than experimental ED values. In addition, interaction indices and confidence intervals confirmed the potentiation between both drugs. Theoretical ED of diethylpropion + topiramate combination did not affect the blood pressure. Data suggests that low doses of the diethylpropion + topiramate combination can potentiate the anorectic effect of individual drugs with a better safety profile, which deserves further investigation in clinical trials.

An outbred strain of rats developed in 1915 by crossing several Wistar Institute white females with a wild gray male. Inbred strains have been derived from this original outbred strain, including Long-Evans cinnamon rats (RATS, INBRED LEC) and Otsuka-Long-Evans-Tokushima Fatty rats (RATS, INBRED OLETF), which are models for Wilson's disease and non-insulin dependent diabetes mellitus, respectively.
The testing of materials and devices, especially those used for PROSTHESES AND IMPLANTS; SUTURES; TISSUE ADHESIVES; etc., for hardness, strength, durability, safety, efficacy, and biocompatibility.
Mutant strains of rats that produce little or no hair. Several different homozygous recessive mutations can cause hairlessness in rats including rnu/rnu (Rowett nude), fz/fz (fuzzy), shn/shn (shorn), and nznu/nznu (New Zealand nude). Note that while NUDE RATS are often hairless, they are most characteristically athymic.
