Definition and Use of Viagra

Viagra is a medication primarily used for the treatment of erectile dysfunction (impotence; inability to get or keep an erection) in men. Additionally, it's also used to manage pulmonary arterial hypertension, a type of high blood pressure that affects the arteries in the lungs and the right side of the heart.

Understanding Sildenafil Citrate: The Active Ingredient in Viagra

The active ingredient in Viagra is sildenafil citrate, a phosphodiesterase type 5 inhibitor (PDE5i). This compound is the main element contributing to the therapeutic effects of the drug. The function of the inhibitor is to block the enzyme PDE5, which in turn allows for relaxation of smooth muscle tissue, facilitating an erection in the presence of sexual stimulation.

The Formulation and Appearance of Viagra Tablets

Viagra is typically supplied as blue, film-coated, rounded-diamond-shaped tablets. Each tablet contains sildenafil citrate equivalent to either 25 mg, 50 mg, or 100 mg of sildenafil, catering to different dosage needs. It is important to note that Viagra is just one brand name for sildenafil; other brands with the same active ingredient are also available.

Inactive Ingredients in Viagra Tablets

Apart from sildenafil citrate, each Viagra tablet also contains a number of inactive ingredients. These include microcrystalline cellulose, anhydrous dibasic calcium phosphate, croscarmellose sodium, magnesium stearate, hypromellose, titanium dioxide, lactose, triacetin, and FD & C Blue #2 aluminum lake. These components do not contribute to the drug's therapeutic effects but play roles in the tablet's formation, stability, and absorption.

Directions for Use: How and When to Take Viagra

As an erectile dysfunction treatment, Viagra is taken as needed. The medication is most effective when taken on an empty stomach one hour before engaging in sexual activity. The dosage varies among individuals and can range from 25 mg to 100 mg. A healthcare provider should determine the most suitable dosage based on the patient's specific needs and conditions. It is crucial not to exceed the prescribed dosage for safety reasons.

Interaction of Viagra with Other Medications: The Case of Nitrates

Like all medications, Viagra may interact with other drugs. Nitrates, a type of medication often prescribed for chest pain or heart conditions, are particularly important to avoid when taking Viagra, due to the risk of a significant drop in blood pressure.
