Brand vs. Generics
Most sales derive from generic formulations due to patent expirations, with branded versions commercially limited but still focusing on brand recognition for patient adherence.
Patent & Exclusivity Landscape
Patents on formulations and delivery mechanisms have mostly expired, bolstering generics’ market share but complicating high-margin sales for proprietary products.
Regulatory and Policy Impacts
FDA Regulations
The Controlled Substances Act classifies phentermine as a Schedule IV drug, necessitating rigorous prescribing and dispensing protocols[6].
EMA & Other Regulatory Bodies
European and Asian markets follow similar strict controls, with approval for use as an adjunct in weight management under specific indications.
Reimbursement Trends
In the U.S., Medicare and Medicaid partially reimburse generic formulations. Policy shifts favor cost-effective treatments, boosting volume[7].
