The expanding patient base for NSAIDs directly propels the demand for formulations like INDOCIN SR. Extended-release formulations are particularly attractive for patients requiring sustained symptom management, leading to increased adherence and better clinical outcomes.
Shift Toward Extended-Release NSAIDs
Extended-release (ER) NSAIDs like INDOCIN SR enable reduced dosing frequency, improved compliance, and minimized peak-trough fluctuations that can cause gastrointestinal (GI) side effects. Market surveys indicate an uptick in physician preference for ER formulations in chronic management schemes.
