Patent expiries reduce exclusivity, increasing generic competition, which can pressure margins. However, developing novel formulations and securing regulatory protections can sustain profitability.
Q2: What are the main competitive advantages of fixed-dose combination therapies in glaucoma?
They improve patient compliance, provide synergistic IOP reduction, and simplify treatment regimens, making them preferred first-line options.
Q3: How significant are emerging markets for the future growth of these drugs?
Emerging markets are vital, accounting for a substantial share of future growth due to increasing disease prevalence and limited existing treatment options, despite regulatory barriers.
Q4: What regulatory factors should companies consider when developing combination formulations?
Companies must demonstrate bioequivalence, safety, efficacy, and gain approval through accelerated pathways where available, considering country-specific requirements.
Q5: Are biosimilars a viable future avenue for these drugs?
While biosimilars are more relevant for biologic drugs, for small molecules like brimonidine and timolol, generics dominate, and biosimilars are less applicable.
