Drug intelligence / Profile preview
nicotine patch + nicotine lozenge is a combination nicotine replacement therapy (NRT) regimen developed and evaluated by the University of Wisconsin-Madison Center for Tobacco Research and Intervention (UW-CTRI). The therapy utilizes a long-acting transdermal nicotine patch to provide steady-state nicotine levels, supplemented by short-acting nicotine lozenges (typically 2 mg or 4 mg) used on an as-needed basis to address breakthrough cravings and acute withdrawal symptoms. Nicotine serves as an agonist at nicotinic acetylcholine receptors (nAChRs) in the brain, substituting for the nicotine previously obtained through tobacco use. This combination approach has been shown in Phase 4 clinical trials to be more effective than nicotine monotherapies for achieving long-term tobacco abstinence.
