Pharmacokinetics of Viagra Professional

The pharmacokinetics of Viagra Professional involve rapid absorption. Once ingested, sildenafil reaches peak plasma concentrations in about an hour. The bioavailability of sildenafil is approximately 40%, influenced by factors like high-fat meals which can delay the drug’s absorption. The half-life of sildenafil averages at four hours, facilitating a window for effectiveness. Its clearance involves hepatic metabolism, predominantly via CYP3A4 and CYP2C9 pathways.

Sildenafil’s distribution is extensive, with a large volume of distribution at steady state. Protein binding is around 96%, indicating high plasma protein affinity. These pharmacokinetic attributes underscore the quick action and effectiveness duration of Viagra Professional, providing an effective solution for erectile dysfunction in many patients.

Viagra Professional Dosage Information

Viagra Professional is commonly administered in dosages of 50 mg or 100 mg. Initial dosages typically start at 50 mg, with adjustments based on individual efficacy and tolerability. Physicians might recommend a 100 mg dosage for patients who do not achieve optimal outcomes at lower doses. Consumption should be limited to once daily, taken approximately one hour before sexual activity.

Alterations in dosage should only occur under medical supervision. Factors such as age, liver function, and other medications can influence the appropriate dosage for a patient. Adherence to prescribed dosages is vital to minimize adverse effects and optimize therapeutic outcomes.

Who Can and Cannot Take Viagra Professional

Viagra Professional is intended for use in adult males with erectile dysfunction. Men seeking this medication should be evaluated for cardiovascular risk factors. Elderly patients might require closer monitoring due to the potential for altered drug metabolism. Women and individuals under 18 years should not use Viagra Professional.

Patients with conditions like severe cardiovascular disorders, significant hypotension, or recent history of stroke or myocardial infarction should avoid this medication. Caution is warranted in those with anatomical penis deformities or conditions predisposing to priapism.

Viagra Professional Interactions

Viagra Professional interacts with several medications. Co-administration with nitrates can cause severe hypotension, thus contraindicated. Alpha-blockers and antihypertensives may also lead to blood pressure reductions. CYP3A4 inhibitors like ketoconazole and erythromycin can increase sildenafil levels, necessitating dosage adjustments.

Grapefruit juice can affect sildenafil metabolism and should be avoided. It’s essential for patients to disclose all current medications to healthcare providers to prevent harmful interactions.
