According to Dr Reddy's, the drugmaker may launch Rivastigmine, an anti-mild-to-moderate Alzheimer's drug, Desloratadine, used to treat allergies and Pseudoephedrine, a nasal/sinus decongestant.

Dr Reddy's Laboratories received a major setback in the US, as a court there granted a motion seeking a preliminary injunction to block the launch of its generic version of Sanofi-Aventis' anti-allergic drug, Allegra D24.

The patent relates to the manufacturing process for the active ingredient in Sanofi-Aventis' Allegra and Allegra-D drug products. Both Dr Reddys and Sandoz are known to be marketing these products in the US.
