It’s a barely a five-minute walk from New Delhi’s Patel Nagar metro station. The lane, bristling with commercial activity, stands out by itself. Sweet shops, bakeries, juice shops, spy camera vendors, or even a small outlet selling Ayurvedic medicines for in-vitro fertility treatment. South Patel Nagar has it all. Amidst all this chaos, in a building with a juice outlet to the front and up a narrow flight of stairs, is Aimil Pharmaceuticals, a little-known company which is kicking up some chaos in the medical world too.
