Here is a very interesting research article about a pharma company looking to be the sole provider of diltiazem ointment (ie, no longer is there a need to find someone to compound it....but easily found already on the counter)!
some interesting facts about how much $$$$ this can make for them and how many people are suffering from different gastrointestinal disorders, in particular see how many are afflicted with anal fissures.
this is a multi-billion dollar industry.
no wonder we don't see ketanserin gel here in the USA for anal fissures. it could put the other two ointments, nilfedipine and diltiazem, out of business! maybe.......
