Sandoz was one of the earliest manufacturers of anti- TB products to receive WHO prequalification for its anti- TB products.  Fixed Dose Combinations (FDCs) developed by Sandoz- Rimstar 4- FDC and Rimactazid 150/75 received EU approval in 2002. Based on the EU approval, Sandoz applied for WHO prequalification. Sandoz products Rimstar 4- FDC (TB085) and Rimactazid 150/75 (TB090) were prequalified in September 2004. Sandoz manufactures its products at Strides Arcolab, India, which is also a WHO prequalified manufacturing site.
