Hi, latest drug on the market I believe is ibsrela. It’s manufactured in Waltham Ma. I tried everything for chronic constipation without success. This was the last drug and I had no success but it is the latest drug out there. I’m now waiting for the next new constipation drug to enter the market.
The company will call you after your Gastro sets it up and they actually gave me 4 months for free. I wish it had worked but I did follow many who said it did.
Best of luck
