FAQs
Q1: What major patents in the PPI class expired recently, and how did that affect market competition?
A: Patents for drugs like omeprazole and lansoprazole expired between 2014–2018 in key markets, facilitating a surge of generic versions and significantly reducing prices. This intensified competition led to thinner profit margins for brand-name manufacturers.
Q2: Are there any breakthrough innovations in PPI formulations currently in the pipeline?
A: Yes, controlled-release formulations, dual-release systems, and P-CAB drugs such as vonoprazan are in advanced stages, promising longer-lasting acid suppression and improved safety profiles.
Q3: How does patent strategizing influence the entry of biosimilars or generics?
A: Patent evergreening, process patents, and formulation patents are used to extend exclusivity. While patent expiry promotes biosimilar entry, litigation and strategic filings can delay market access.
Q4: What regions are experiencing the fastest growth for PPIs, and why?
A: China and India are experiencing rapid growth due to increasing prevalence of GIT disorders, expanding healthcare infrastructure, and favorable regulatory policies promoting generic manufacturing.
Q5: How might upcoming regulatory changes impact the PPI patent landscape?
A: Adjustments to patent law, SPC regulations, and approval pathways for biosimilars could either extend patent protections or expedite generic entry, influencing market competition.
