Challenges
- Financial exhaustion and reimbursement limitations: In 2023, the Federal Joint Committee (G-BA) of Germany released the Act on the Reorganisation of the Pharmaceutical Market (AMNOG), mandating 20.3% price cuts on combination products. Despite having a positive effect on affordability, such government control on pricing often makes it harder for manufacturers to curate their desired profit margin from the guaifenesin market. Besides, U.S. Medicaid covered only 35.7% of prescriptions till 2024, as per the Centers for Medicare & Medicaid Services (CMS). These restrictive policies are limiting adoption of prescribed formulations, and hence hindering revenue generation in this sector.
- Patent expirations and generic erosion: The revenue challenges from patent expirations are discouraging new entrants from getting involved in long-term trading affairs in the guaifenesin market. This can be exemplified by the $150 million brand-name sales loss by Teva within just six months following its 2023 patent cliff, as unveiled by the U.S. Securities and Exchange Commission (SEC). This rapid failure of branded products in delivering optimum performance highlights the intense competitive pressure from generic alternatives available in this field. However, innovator companies need to accelerate product lifecycle strategies and amplify differentiation efforts to avoid such downfall.
