Subclasses in ATC: G02C - OTHER GYNECOLOGICALS
Market Dynamics and Patent Landscape for ATC Class: G02C – Other Gynecologicals
Executive Summary
The ATC classification G02C pertains to "Other Gynecologicals," encompassing pharmaceutics targeted predominantly at gynecological disorders not classified under more specific categories such as hormonal contraceptives or anti-infectives. Although historically overshadowed by well-established categories like G02A (Oestrogens), G02B (Progestogens), and G02F (Gynaecological anti-infectives), G02C has experienced notable growth driven by innovations in therapeutics and diagnostics for gynecological conditions such as fibroids, endometriosis, and menopause-related symptoms.
Market trends indicate a rising demand owing to increased awareness, an aging female population, and advances in biotechnology. Simultaneously, the patent landscape reveals a competitive space characterized by incremental innovations, patent expirations, and strategic filings aiming at expanding product pipelines for gynecological indications. This report synthesizes current market dynamics, highlights key patent filings, and forecasts future landscape developments.
