Pharmacokinetics

Viagra Professional contains sildenafil citrate, a potent phosphodiesterase type 5 inhibitor. It enhances erectile function by increasing blood flow to the penis. Absorption occurs rapidly. Peak plasma concentrations are observed within an hour after oral administration. Sildenafil demonstrates a dose-proportional pharmacokinetic profile.

The half-life of sildenafil is approximately 4 hours. Metabolism primarily occurs via hepatic pathways, involving cytochrome P450 enzymes. Elimination is mainly through the feces and, to a lesser extent, the urine. Patients with renal or hepatic impairment may exhibit altered pharmacokinetics.

Correct Use

Patients should take Viagra Professional approximately 30 minutes to an hour before sexual activity. It’s crucial to adhere to the prescribed dosage, commonly 50 mg or 100 mg. Maximum dosage frequency is once per day. Intake with a high-fat meal can delay absorption, thus affecting its efficacy.

Swallow the tablet whole with water. Avoid alcohol consumption when using sildenafil 100 mg, as it can amplify side effects. Patients should not adjust the dose without consulting their healthcare provider. Report any adverse reactions or efficacy concerns to a healthcare professional promptly.

Warning & Precautions

Viagra Professional is contraindicated in patients taking nitrates. This combination can result in a severe drop in blood pressure. Patients with cardiovascular conditions should consult a healthcare provider before use. Other contraindications include severe hepatic impairment, recent stroke, or myocardial infarction.

Patients should disclose their complete medical history. This includes allergies, medications, and existing health conditions. Caution is advised in patients with anatomical deformation of the penis. Users should also be aware of potential drug interactions with alpha-blockers, antifungals, and HIV protease inhibitors.

Pregnancy and Breastfeeding

Viagra Professional is not indicated for use in women. Its safety during pregnancy or breastfeeding has not been established. Although unlikely, accidental ingestion by women of childbearing age should be reported to a healthcare provider.

Men intending to father a child should discuss use with their healthcare provider. Effects on fertility or conception are not well documented. Any concerns related to reproduction should be addressed with a qualified professional.

Viagra Professional Signs and Symptoms of Overdose

Overdose of Viagra Professional can result in severe adverse effects. Symptoms may include nausea, chest pain, irregular heartbeat, and prolonged erection. In case of suspected overdose, seek immediate medical attention.

Do not exceed the recommended dose. Avoid use of other erectile dysfunction medications concurrently. Responsible use of Viagra Professional is vital to prevent potential health risks.

Purchasing Viagra Professional Without a Prescription

Viagra Professional should be purchased with a valid prescription. Online sales without prescription often involve counterfeit products. These can be ineffective or harmful.

Consult a licensed healthcare provider for an appropriate prescription. They will assess suitability and provide a safe dosage regimen. Purchase only from reputable pharmacies to ensure authenticity and safety.
