Phentermine Hydrochloride Market Driver - Rising Global Obesity Prevalence and Chronic Disease Burden

The rising rates of obesity across the world are a crucial element that contributes towards the pressure to purchase phentermine hydrochloride which is one of the most popular appetite suppressants that are frequently prescribed in weight control. Obesity as a great public health issue is a significant risk factor that increases the chances of contracting chronic illnesses like type 2 diabetes, cardiovascular diseases and hypertension, which further increases demand of effective therapeutic intervention.

With the growing sedentary way of life and changing dietary habits towards high-calorie, processed foods, the number of people developing excessive weight gain all over the world keeps growing. This increased compliance of comorbidities related to obesity makes the health care providers identify the need to focus on pharmacological interventions and lifestyle changes to aid the reduction of weight and positively influence patient outcomes.

In September 2025, the World Health Organization (WHO) reported a sharp rise in the global burden of chronic or non-communicable diseases, which claimed around 43 million lives in 2021 accounting for 75% of non-pandemic-related deaths. The data highlighted cardiovascular diseases, cancers, chronic respiratory conditions, and diabetes as the leading causes, with 80% of premature deaths occurring in low- and middle-income countries.  

Phentermine Hydrochloride Market Opportunity - Development of Extended-Release and Novel Delivery Formulations

The global phentermine hydrochloride market is a great growth potential due to the innovation of extended-release (ER) and new formulations of delivery. The conventional immediate-release formulations of phentermine hydrochloride have multiple doses per day, which may result in reduced patient compliance and varying plasma drug concentrations. Extended-release preparations are said to maximize therapeutic effects because they ensure more consistent drug levels, decreased adverse effects, and easier dosing schedules because they should be administered once a day.

Moreover, the development of drug delivery technologies like transdermal patches, intranasal sprays, or sublingual films would transform the treatment of obesity due to the availability of the non-oral routes with increased bioavailability and convenience to patients. These innovations meet the increased need in customized medicine and serve the needs of the populations with ingestion challenges or gastrointestinal disorders.

For example, Orexigen Therapeutics, Inc. and Takeda Pharmaceutical Company Limited developed Contrave, an extended-release formulation combining phentermine and bupropion, offering a once-daily regimen to improve patient compliance and therapeutic consistency. Hikma Pharmaceuticals advances extended-release versions of obesity treatments, enhancing drug delivery for better bioavailability, sustained effects, and improved patient adherence in a competitive market.
