Revised Prescribing Info for Pfizer’s Chantix
FDA has approved changes to the prescribing information for Pfizer’s Chantix (varenicline) that specifies that the drug is not recommended for pediatric patients 16 years of age or younger because its efficacy in this population has not been demonstrated. Chantix is a nicotinic receptor partial agonist indicated for use as an aid to smoking cessation treatment. It was originally approved by the FDA in 2006 for adult use.
An agency notice says the revised labeling is based on data from two studies of varenicline in adolescent patients: a multiple-dose pharmacokinetic and safety study and a placebo-controlled study that evaluated efficacy and safety for smoking cessation (abstinence). Data showed that use of varenicline did not significantly increase abstinence rates in this population.
