Drug Marketing Warning Letter Sent to Vanthi

Share

CDER’s Office of Prescription Drug Promotion (OPDP) has sent Vanthi (Newtown, PA) a Warning Letter objecting to a medical conference marketing panel for its Lomaira (phentermine hydrochloride USP) tablets. “This panel makes false or misleading claims and/or representations about the risks associated with Lomaira and omits material facts,” the OPDP letter says. The drug is indicated as a short-term (a few weeks) adjunct for weight reduction as part of a comprehensive treatment plan.

 

The panel makes several representations about the drugs benefits such as “THE POWER OF THREE” “Diet” “Exercise” “Lomaira” and it states “Consider adding Lomaira to your patients’ weight-management plan.” However, OPDP says, the panel is misleading because it fails to state that the drug is indicated for short-term adjunct use in a “regimen of weight reduction based on exercise, behavioral modification and caloric restriction in the management of exogenous obesity.”

 

The Warning Letter asks that the company stop misbranding the product with these or similar misleading claims.
