Like many prescription drugs, varenicline was motivated by a design template currently existing in nature: cytisine, an alkaloid in the seeds of the golden rain tree, belonging to main and southern Europe. Like varenicline, cytisine is a partial agonist of nicotinic acetylcholine receptors in the brain. Cytisine has been utilized as a smoking-cessation aid in the formerly communist states of Eastern Europe for years, where it costs less than $30 for a 25-day course.

A new randomized trial in the New England Journal of Medication is the first to check cytisine against nicotine replacement therapy. 1,310 cigarette smokers in New Zealand who had actually called the national quit hotline were randomized to get either cytisine for 25 days or nicotine replacement therapy for 8 weeks. The therapies were supplied totally free or at extremely low expense.

Extab likewise funded a previous stage III trial, released in 2011, showing cytisine's superiority over placebo. After a month, 40% of cytisine-takers reported constant abstaining, compared to 31% of those getting nicotine replacement. The advantages held at 6 months, when 22% of those taking cytisine reported smoking abstinence compared to 15% of those using nicotine replacement.

It might be too soon to state: about 5% of patients taking cytisine reported "sleep disorders" (due to dreams?) or nausea; unusual dreams and nausea are amongst the most typical reported side results of varenicline.

The FDA declined a 2006 request by supplement manufacturers to market cytisine as a supplement in the U.S., citing absence of security information. Extab hopes additional well-conducted medical trials will overcome those issues and establish cytisine's place as a safe and effective cigarette smoking cessation aid.
