Weight Loss Drugs Market Segment Insights
By Drug Type
In 2024, prescription drugs dominated the weight loss drugs market, capturing 64.5% of the global share. Medications such as Wegovy (semaglutide) and Saxenda (liraglutide) lead this category, offering proven clinical efficacy and regulatory backing. Growing awareness of medical weight management solutions, combined with endorsements from organizations like the American Medical Association (AMA) and the CDC, has positioned prescription therapies as the preferred choice for physicians and patients alike.
The over-the-counter (OTC) segment is expected to grow steadily, driven by increased consumer interest in non-prescription solutions, though prescription therapies will continue to dominate in terms of revenue.
By Mechanism of Action
The appetite suppressants segment led the market with a 51.2% share in 2024. Drugs such as Contrave (naltrexone/bupropion) and phentermine are widely prescribed for their ability to reduce hunger and caloric intake effectively. Appetite suppressants offer a straightforward mechanism, aligning with patient preferences for manageable, sustainable weight loss strategies.
Other mechanisms including fat absorption inhibitors and metabolic enhancers are gaining traction with the development of novel formulations and combination therapies aimed at enhancing treatment outcomes.
By Distribution Channel
Hospital pharmacies accounted for the largest share of the market at 46.1% in 2024. Their dominance is attributed to the controlled environment for prescribing and monitoring patients, particularly those with comorbidities like Type 2 diabetes or cardiovascular disease. Hospitals also play a key role in educating patients, ensuring adherence, and managing side effects.
Retail pharmacies and online channels are expected to see rapid growth as accessibility improves and consumer demand rises, particularly in emerging markets.
