Abstract
Topical polyethylene glycol based formulations for the delivery of 2-substituted-1-naphthols and indoles and particularly, 2-phenylmethyl-1-naphthol are provided. Said topical formulations exert excellent localized antiinflammatory activity while demonstrating low levels of skin penetration in vitro and in vivo thereby reducing unwanted side effects and reducing systemic toxicity associated with the active drug compounds.
