Zenegra 100 mg contains sildenafil citrate, which is a medication used to treat erectile dysfunction (ED) in men. Here’s how Zenegra 100 mg works to treat ED:
Mechanism of Action: Sildenafil citrate is classified as a phosphodiesterase type 5 (PDE5) inhibitor. It works by inhibiting the enzyme PDE5, which regulates blood flow in the penis. During sexual stimulation, nitric oxide is released into the erectile tissue of the penis, which activates the enzyme guanylate cyclase. This enzyme increases levels of cyclic guanosine monophosphate (cGMP), which relaxes the smooth muscles of the penis and allows blood to flow into the erectile tissues, producing an erection.
Enhanced Blood Flow: By inhibiting PDE5, sildenafil citrate helps to maintain higher levels of cGMP in the erectile tissue. This results in improved blood flow to the penis, facilitating the ability to achieve and maintain an erection sufficient for sexual activity.
Onset and Duration: Zenegra 100 mg is typically taken orally, with effects typically beginning within 30 to 60 minutes after ingestion when the man is sexually aroused. The effects of sildenafil citrate can last up to 4 to 6 hours, allowing for a period of improved erectile function during this time frame.
Efficacy: Clinical studies have shown that sildenafil citrate, including in formulations like Zenegra 100 mg, is effective in treating ED in a significant number of men. It has been shown to improve erectile function across various underlying causes of ED, including psychological factors, physical conditions, and medication side effects.
Safety Considerations: While generally considered safe and effective for many men, sildenafil citrate should be used cautiously in individuals with certain medical conditions (such as cardiovascular disease, liver or kidney impairment) and when interacting with certain medications (particularly nitrates used for chest pain). It’s important for individuals to consult with a healthcare provider before starting Zenegra 100 mg to ensure it is safe and appropriate for their individual health status.
In conclusion, Zenegra 100 mg treats ED by enhancing blood flow to the penis through its action as a PDE5 inhibitor. It helps restore erectile function in men when they are sexually stimulated, allowing for improved sexual performance during the period of its effectiveness.  |
