Ivermectin is not protected by a patent. The drug's original patents expired decades ago [1][2]. Ivermectin was first patented in the early 1970s by Merck, and these patents have since expired, meaning the drug is in the public domain [2].
Who discovered ivermectin and when was it patented?
Ivermectin was discovered by scientists at Merck & Co. in the 1970s. Development began after researchers identified its potent antiparasitic properties. The drug was first patented in the early 1970s, with key patents for its use and manufacturing expiring in the early 2000s [1][2].
Can ivermectin be manufactured by any company?
Yes, because the original patents have expired, any pharmaceutical company can manufacture and sell ivermectin without needing a license from Merck [1][2]. This has led to the availability of generic versions of the drug worldwide.
What is the difference between ivermectin and its patents?
The patents on ivermectin covered specific aspects of the drug, such as its chemical composition, methods of manufacturing, and specific therapeutic uses. Once these patents expired, the drug itself entered the public domain, meaning its fundamental intellectual property protection lapsed [1][2]. New patents might exist for novel formulations, delivery methods, or specific new uses of ivermectin, but these do not cover the drug as a whole or its initial development.
