When working with Vardenafil, a prescription phosphodiesterase‑5 (PDE5) inhibitor used to treat erectile dysfunction. Also known as Levitra, it helps improve blood flow to the penis during sexual stimulation. The drug belongs to the same class as Sildenafil, the active ingredient in Viagra, another PDE5 inhibitor and Tadalafil, the long‑acting PDE5 inhibitor marketed as Cialis. Vardenafil works by blocking the enzyme PDE5, which allows cyclic guanosine monophosphate to accumulate and relax smooth muscle tissue. This physiological change enables erections in response to sexual arousal. The central condition it addresses is erectile dysfunction, a common issue where a man cannot achieve or maintain an erection sufficient for intercourse, affecting millions worldwide.
Understanding dosage and timing is crucial. Typical starting doses range from 5 mg to 20 mg taken about an hour before sexual activity, and the effect lasts up to five hours—shorter than tadalafil but longer than some alternatives. Food can delay absorption, especially high‑fat meals, so a light snack is advisable. Side effects often mirror those of other PDE5 inhibitors: headache, flushing, nasal congestion, and occasional visual changes. Most users experience mild symptoms that resolve on their own, but anyone with cardiovascular disease should consult a doctor because the drug can affect blood pressure. Interactions with nitrates, certain antihypertensives, and alpha‑blockers are contraindicated, making a medication review essential before starting therapy.
