What We Do

At Botanix Pharma, we are dedicated to developing next generation therapeutics for the treatment of serious skin diseases.

Our mission is to improve the lives of patients battling acne, psoriasis and atopic dermatitis, by providing new treatment options for conditions that currently are inadequately addressed or are treated with therapeutics that are burdened with side effects profiles.

We are harnessing the untapped potential of a synthetic active pharmaceutical ingredient known as cannabidiol which is currently being studied for the treatment of epilepsy, pain, arthritis and schizophrenia amongst other indications. Botanix is preparing for the first human trials utilizing synthetic cannabidiol in a proprietary drug delivery system (Permetrex™) for direct skin delivery of the therapy.
