Recently, our team has been assigned to handle HIV drug. Then I came to know that this V drug capsule was made from porcine (pork gelatin haram), which it is unacceptable to most Muslim consumers. According to most of the pharmacist, many Muslim consumers prefer tablets rather than gelatin capsules.
Gelatin has long been the substance that capsules are made from. The main source of gelatin is collagen, which is found in the skin and bones of animals. Most of the softgel capsules on the market are made from an animal source; bovine (from beef/cows), porcine (pork/pigs) & ovine (lamb/sheep). For the Indian market, in which Hindus shun bovine products & Muslims shun porcine products, non-gelatin capsules are a natural fit. That is why more recently, vegetable-based capsules have become a preferred form.
