Black viagra 200mg is a powerful medication used to treat erectile dysfunction (ED), primarily containing Sildenafil Citrate. Sildenafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow in the penis. During sexual stimulation, nitric oxide is released in the penile tissue, stimulating the production of cyclic guanosine monophosphate (cGMP). cGMP relaxes smooth muscles and increases blood flow to the corpus cavernosum, leading to an erection.
By blocking PDE5, Sildenafil prevents the breakdown of cGMP, thereby enhancing and prolonging the erection process. This allows men with ED to achieve and maintain an erection sufficient for sexual activity.
Cenforce 200 mg is typically taken 30 to 60 minutes before sexual activity, and its effects can last up to four hours. It is essential to follow medical advice regarding dosage to minimize potential side effects such as headaches, flushing, or dizziness. Understanding the science behind Sildenafil helps in appreciating its role in effectively managing ED, and improving both sexual health and confidence.
