FAQs
1. What are the key patent expiration dates for major dopamine agonists?
Primary patents for drugs like pramipexole expire around 2025–2028, while ropinirole’s patents are set to expire in 2018 but may be extended through formulation patents or litigation.
2. How does receptor subtype selectivity influence future drug development?
Receptor subtype selectivity, especially targeting D3 over D2 receptors, aims to minimize side effects like impulse control disorders, thus improving patient tolerability and expanding therapeutic indications.
3. Which markets present the most growth opportunities?
Emerging markets such as China, India, and Brazil offer substantial growth due to increasing approval rates, unmet clinical needs, and expanding healthcare infrastructure.
4. Are biosimilars impacting the dopamine agonist market?
While biosimilars are more prominent in biologics, generic small molecule dopamine agonists have caused price reductions post-patent expiry, affecting margins and R&D focus.
5. What are the primary challenges facing new entrants in this landscape?
High R&D costs, complex regulatory pathways, patent litigation, and established competitors with extensive patent portfolios pose significant barriers to new market entrants.
