India's cancer drug margin pilot (2019)
The government capped trade margins on 42 anti-cancer drugs at 30%, allowing a maximum markup of 42.8% over the price to the stockist. Maximum retail prices fell on 526 brands, with some cuts reaching 90%.
Prices dropped sharply for the covered brands.
An AIDAN review found prices of 38 of 50 overlapping drugs rose afterward, and markups above the threshold returned before the 2026 order.
The 2026 cap is the second round of the same policy, and the 2019 experience is the main evidence that margin caps can erode.
