Fildena Chewable 100 mg is during storage, I found that Fildena CT 100 is a sildenafil citrate 100 mg chewable tablet. The manufacturer/supplier information lists a 3-year shelf life for some Fildena CT 100 listings, while another supplier lists 24 months, so the exact stability period depends on the specific manufacturer/batch and approved packaging. F Fortune Healthcare Product Pvt Ltd +1 For the formulation itself, published research on sildenafil 100-mg rapid-dissolving tablets found that tested formulations remained physically and chemically stable for 6 months at ambient room temperature, with ***** remaining above 95% and no significant degradation detected. However, that study used compounded formulations, not necessarily the commercial Fildena product, so it shouldn't be used to assign Fildena's expiry date. P PubMed What matters for your Fildena Keep it in its original blister/packaging and protect it from moisture, heat, and direct sunlight. Follow the expiry date printed on your specific strip/box rather than assuming a generic 2- or 3-year stability period. If the tablet has changed color, texture, smell, or is damaged, don't use it. 100 mg sildenafil is a high dose; it should not be taken more than once in 24 hours unless specifically prescribed. If you're asking about the actual pharmaceutical formulation—excipients, pH, dissolution, degradation products, and ICH stability testing (25°C/60% RH, 30°C/65% RH, 40°C/75% RH), I can explain that in technical detail.
