 Pfizer is now moving ahead with a daily weight loss pill. Last winter, Pfizer decided to end a trial of a pill that you take twice a day after 50% of the participants reported experiencing side effects like nausea and vomiting. The company deciding to instead channel its efforts into creating a pill patients would only take once a day. Pfizer will be developing the pill through the end of the year and will start trials after that to determine the safety and efficacy and tolerability before submitting it to the FDA for approval.
