Virpax Pharmaceuticals, Inc. announced that it has filed a new provisional patent application with the United States Patent and Trademark Office entitled "NSAID Formulation and Method" related to its Epoladerm?? product candidate. Epoladerm is an over-the counter (OTC) diclofenac topical spray film that Virpax is developing for pain associated with Osteoarthritis.

Epoladerm is designed to be less messy than gels or creams which are applied by hand and which may contaminate public water supplies with the active pharmaceutical ingredients the gels or creams carry.
