American companies that manufacture ivermectin?

Manufacturers of Ivermectin in the United States

Several American companies have been involved in the production or manufacturing of ivermectin, an antiparasitic medication and potential antiviral treatment. While patent holders and pharmaceutical companies play a significant role, research institutions and other entities may also contribute to the drug's development or formulation.

Merck & Co., Inc.

Merck & Co., Inc., the original developer of ivermectin, is a major player in the global ivermectin market. [1] The company has been granted multiple patents for ivermectin, including US Patent No. 4,761,485, which was issued in 1988. [2] However, some of these patents have expired. [3] Merck still manufactures and supplies ivermectin, and it's unclear whether others can produce generic versions.

GlaxoSmithKline (GSK)

GlaxoSmithKline (GSK) has a licensing agreement with Merck for the production and distribution of ivermectin, known as Stromectol, in some countries, including the United States. GSK does not manufacture ivermectin but helps distribute the medication. [4]

Other Companies and Research Institutions

It is essential to note that other pharmaceutical companies and research institutions might be involved in ivermectin-related activities, such as developing new formulations, conducting clinical trials, or researching potential applications. These entities could be engaged in ivermectin production or research in the United States.

Patent Expiration and Competition

The patent expiration of ivermectin has been a subject of discussion. However, some patent filings by Merck have been made public, which could delay generic versions of ivermectin entering the market. [5]
