Tapinarof, also known as benvitimod and sold under the brand name Vtama, is a medication used to treat plaque psoriasis.[1][2] It is applied to the skin.[1]

Common side effects include folliculitis, itchiness, and contact dermatitis.[1] It is an aryl hydrocarbon receptor activator.[1]

Tapinarof was approved for medical use in the United States in 2022.[1] It is not approved in either Europe or the United Kingdom as of 2022.[3] In the United States 60 grams of 1% cream costs about 1,400 USD as of 2022.[4]

Medical uses

Tapinarof is indicated for the treatment of plaque psoriasis in adults.[1]


It is applied as a 1% cream once per day.[1]

Society and culture


Tapinarof is the International Nonproprietary Name (INN).[5]

Natural occurrence

Entomopathogenic nematodes emerging from a wax moth cadaver.

It is a naturally occurring compound found in bacterial symbionts of nematodes which has antibiotic properties.[6][7]

Tapinarof, also known as benvitimod, is a bacterial stilbenoid produced in Photorhabdus bacterial symbionts of Heterorhabditis nematodes. It is a product of an alternative ketosynthase-directed stilbenoid biosynthesis pathway. It is derived from the condensation of two β-ketoacyl thioesters.[6] It is produced by the Photorhabdus luminescens bacterial symbiont species of the entomopathogenic nematode, Heterorhabditis megidis. Experiments with infected larvae of Galleria mellonella, the wax moth, support the hypothesis that the compound has antibiotic properties that help minimize competition from other microorganisms and prevents the putrefaction of the nematode-infected insect cadaver.[7]
