Kamagra 100 mg is a medication widely used to treat erectile dysfunction (ED) in men. Its active ingredient, sildenafil citrate, is a phosphodiesterase type-5 (PDE5) inhibitor that enhances blood flow to the penile tissues during sexual stimulation. This increased circulation helps men achieve and maintain a firm erection, improving sexual performance, confidence, and overall satisfaction. Common side effects may include headache, flushing, nasal congestion, dizziness, or mild indigestion.

Tadalista CT 20 mg is essentially a chewable form of tadalafil with the same active ingredient, giving you the long‑acting benefits of tadalafil but in a more convenient, chewable format. It can be very effective for ED, but like all PDE‑5 inhibitors, it must be used carefully and under a doctor’s guidance because of potential risks and drug interactions. As a PDE‑5 inhibitor, tadalafil in this tablet inhibits the PDE‑5 enzyme, which increases levels of cGMP.

Tadalista 40 mg is usually taken orally 30–60 minutes before sexual activity, and its effects can last up to 36 hours, allowing for a more spontaneous sexual experience. The 40 mg dose is considered a higher-strength option for men who do not respond adequately to lower doses. Dosage adjustments should always be made by a healthcare professional. It is recommended to avoid excessive alcohol and high-fat meals before taking the tablet, as these may reduce its effectiveness.

Avana 50 mg is a formulation of the PDE‑5 (phosphodiesterase type 5) inhibitor avanafil, indicated for adult men with erectile dysfunction (ED), i.e., difficulty in achieving or maintaining an erection sufficient for sexual intercourse. During sexual stimulation, nitric oxide (NO) is released in the penile tissue, leading to increased cyclic guanosine monophosphate (cGMP) levels, which cause smooth‑muscle relaxation and increased blood flow into the corpus cavernosum.

Valif 20 mg (Vardenafil) works by inhibiting the enzyme PDE5 (phosphodiesterase type 5). In a healthy man, sexual arousal causes the release of a chemical called nitric oxide in the penis. Nitric oxide helps to increase levels of cGMP, which causes the blood vessels in the penis to relax and expand, allowing more blood to flow in. PDE5 normally breaks down cGMP, but Vardenafil blocks this process, allowing cGMP to accumulate, thereby increasing blood flow and helping produce an erection.
