Sildigra Black Force 200mg contains Sildenafil Citrate, the same active ingredient found in Viagra, but in a higher dosage. Sildenafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which allows increased blood flow to the penis during sexual arousal. This increased blood flow helps men achieve and maintain an erection strong enough for sexual activity.
