Not easy. Your bet would be a supplier of this drug to take on the domain (or some kind of knowledge base), being "the Ramipril organisation"...an exclusive resource for this drug. A bit too niche / too narrow, IMO. From what I read, its a prescription drug too. Only in "COM" would I see some green, if sold to the appropriate buyer
Take a drug like Aspirin. I'd consider the "ORG" or "NET" of this to be fine, based on how common it is. A different class, in that respect
