The Thai generic of Ramipril is called Ramicard.
As a non-American national, I was interested/surprised at the prices you quoted for your medications from Costplusdrugs.com having, like others, always assumed that people in the US paid exorbitant prices for their medications - with or without insurance. Costplusdrugs, however, is not representative of US pharmacies, is it?
It started business (as Mark Cuban Cost Plus Drug Company) only in January 2022, i.e., it is less than 12 months old. It is intended to manufacture and distribute its own generic drugs, thus skipping the middlemen with the intention of "disrupting the pricing of as many drugs as we possibly can" and "disrupt the drug industry and to do our best to end ridiculous drug prices" (https://costplusdrugs.com/mission/). According to Forbes, Mark Cuban's "Real Time Net Worth as of 9/5/22 is $4.6 Billion, and he ranks #578 in the world today" (https://www.forbes.com/profile/mark-...h=62b4a8ff6a04). The firm does not accept medical insurance payments.
Costplus works with a "trusted fulfillment partner, Truepill" that "provides best-in-class pharmacy services" (https://costplusdrugs.com/providers/). Truepill states that "in 2019, we were proud to be featured in the Forbes “Next Billion-Dollar Startup” list (https://truepill.com/company).
The answer to your repeated question, therefore, is that Thai drugstores cannot compete in selling generic medications - imported or otherwise - at lower costs than a single, new, US-based pharmaceutical company with a billionaire founder and a trusted fulfillment partner that is also in the billionaire class. I am sure, however, posters - American and otherwise - will be interested to learn whether Costplus Drugs makes overseas deliveries.
