Combination of varenicline and nicotine lozenges found to increase smoking abstinence

People who smoke looking for to overcome their dependancy could have a brand new remedy choice following the outcomes from a medical trial led by Monash College, which discovered a mixture of varenicline and nicotine lozenges considerably improved smoking abstinence in comparison with varenicline alone. The work is published within the journal JAMA Community Open.

Each varenicline and nicotine lozenges (a type of nicotine substitute remedy) are drugs generally used for smoking cessation. Varenicline is the simplest single remedy at the moment out there for smoking cessation.
