Nicotine replacement therapy for smoking cessation

Priyanka Chauhan, Asish Dev, Seema Desai, Varsha Andhale


Smoking is a process that involves inhaling smoke of burning tobacco. The inhaled tobacco smoke consists of over four thousand chemicals mainly nicotine, tar, carbon monoxide, which is responsible for death causing diseases. Every year 6 million people die because of tobacco consumption.  To overcome the risk of death, various smoking cessation therapies are followed which include cold turkey, non-NRT, e-cigarette and NRT. This review focuses on NRT which basically provides nicotine in order to relieve craving and withdrawal symptoms. NRT consists of various types of formulations gum, patch, lozenge, inhaler, and spray. This strategy is also proved to be effective in combination but the selection of dosage form varies from patient to patient.
