Multiple pharmaceutical manufacturers produce generic versions of ivermectin. These companies typically enter the market after the exclusivity periods for the branded drug have ended [2].
How does generic ivermectin compare to brand-name Stromectol?
Generic ivermectin is bioequivalent to brand-name Stromectol, meaning it contains the same active ingredient and is absorbed by the body in the same way. Regulatory agencies like the U.S. Food and Drug Administration (FDA) require generic drugs to meet strict standards for quality, safety, and efficacy before they are approved [4]. The primary difference is usually the cost, with generics being significantly less expensive [5].
What is the difference between Stromectol and other ivermectin uses?
While Stromectol is specifically approved for certain parasitic infections, ivermectin as a drug substance is used for various applications [1]. Some uses, particularly those investigated during the COVID-19 pandemic, have not been approved by regulatory bodies due to a lack of demonstrated efficacy and safety in robust clinical trials [6]. It is important to use ivermectin only as prescribed by a healthcare professional for approved indications [1].
What is the regulatory status of ivermectin?
Ivermectin is an FDA-approved drug for specific parasitic infections [1]. However, the FDA has not approved ivermectin for the treatment of COVID-19, and it has issued warnings against using veterinary formulations of ivermectin in humans [7].
Where can I find more information on drug patents?
