Scilex Pharma NDA Approved for Pain Patch
FDA has approved a Scilex Pharmaceuticals NDA for ZTlido (lidocaine topical system) 1.8%, indicated for relieving pain associated with post-herpetic neuralgia (post-shingles pain). The anhydrous topical system is based on a novel technology that is designed to achieve superior adhesion and drug delivery efficiency, according to the company. “ZTlido only requires 36 mg/topical system versus 700 mg/patch of Lidoderm) (lidocaine patch 5%), the U.S. reference product, to achieve the same therapeutic dose of drug,” it says. “The safety and efficacy of ZTlido was bridged to Lidoderm in comparative pharmacokinetic studies that demonstrated bioequivalence between products.”
