Safety and efficacy of a rapid-acting topical 4% lidocaine gel in a unique drug delivery system.
Ideally, topical anesthetics should provide rapid analgesic action without causing toxic blood levels of lidocaine or other side effects. Various formulations of lidocaine as a topical anesthetic have been tested and are currently on the market. Here, the authors report on a topical lidocaine with a novel delivery system that provides a rapid onset of action without toxic plasma els of lidocaine. ⋯ Topical 4% lidocaine gel with a unique drug delivery system produces significant anesthesia without occlusion in approximately 25-30 minutes with optimal effects observed between 35-40 minutes after application. Topical 4% lidocaine gel can be used effectively and safely as a topical anesthetic in the physician's office.
