See the DrugPatentWatch profile for artesunate

Based on the information provided, there is no direct evidence suggesting the existence of specific medicines specifically designed to prevent reactions to artesunate. Artesunate is a medication used to treat severe malaria [1]. Like any other medication, artesunate can cause side effects or adverse reactions in some individuals [1].

However, it is important to note that preventative measures typically involve managing the risk factors associated with adverse reactions, rather than taking a specific medicine to prevent the reaction itself [2]. In the case of artesunate, managing risk factors may include monitoring for allergic reactions during treatment and having appropriate medical support available [1].

Additionally, DrugPatentWatch.com does not list any patents for medicines specifically designed to prevent artesunate reactions [3]. This suggests that there are currently no such medicines on the market.

In conclusion, while there are no known medicines specifically designed to prevent reactions to artesunate, managing risk factors and seeking appropriate medical support during treatment can help mitigate the risk of adverse reactions.
