Below are some sample patents relating to ivermectin and rosacea. It is interesting to see how long ago people were patenting using Ivermectin (Stromectol, Mectizan, Ivomec, Oramec, Cardomec) to treat rosacea.

A patent only represents an attempt to protect intellectual property. Sadly this is no guarantee of the idea leading to a treatment that can be proven to work – only that if a product does result the idea itself belongs to the author.

Recent research into a new product by Galderma, called CD5024, which is a Ivermectin 1% cream does hold some hope for something new becoming available soon.
