Pharmacokinetics

The pharmacokinetic profile of Levitra Professional is fundamental for its therapeutic efficacy. Vardenafil, the active ingredient, is rapidly absorbed. Peak plasma concentrations occur within an hour post-administration. The presence of food in the gastrointestinal tract can delay absorption. The bioavailability of the 20mg dosage is approximately 15%. This lower bioavailability is compensated by its higher potency compared to other PDE5 inhibitors.

The elimination half-life of Vardenafil is about 4-5 hours. The drug is metabolized in the liver by CYP3A4, with contributions from CYP3A5 and CYP2C9. Renal clearance plays a minor role. The major circulating metabolite, M1, retains pharmacological activity. It contributes significantly to the overall therapeutic effects.

Levitra Professional Use

Levitra Professional targets erectile dysfunction. Vardenafil enhances blood flow to the penile region, facilitating erection during sexual arousal. This mechanism involves inhibition of the phosphodiesterase type 5 enzyme, which degrades cGMP in the corpus cavernosum. Increased cGMP leads to smooth muscle relaxation and vasodilation.

Recommended initiation involves a 20mg dosage. Titration is necessary based on efficacy and tolerability. Patients must administer the tablet approximately 30 minutes before anticipated sexual activity. Daily consumption is discouraged to mitigate potential adverse reactions.

Levitra Professional Contraindications

Contraindications for Levitra Professional are extensive. Patients with hypersensitivity to Vardenafil or any formulation components must avoid use. Nitrate therapy in any form is a strict contraindication due to the risk of severe hypotension.

Concomitant use with guanylate cyclase stimulators like riociguat is prohibited. Patients with severe hepatic impairment or end-stage renal disease requiring dialysis should not consume Levitra Professional. The safety profile in these populations is inadequate.

Missed Dose

Levitra Professional is taken as needed, not on a scheduled regimen. A missed dose is irrelevant to its administration. Patients should not double the dosage to compensate. Adherence to guidelines ensures optimal outcomes.

How to Cope with Side Effects of Levitra Professional

Adverse effects vary in intensity and frequency. Common reactions include headache, flushing, and nasal congestion. Transient visual disturbances may occur. A strategic approach involves dosage adjustment and symptomatic treatment.

In rare instances, priapism can develop. This requires immediate medical intervention. Patients experiencing angina or myocardial symptoms post-ingestion should seek urgent care. These scenarios are indicative of cardiovascular risk.

Levitra Professional Over the Counter

Levitra Professional requires a prescription. It is not available over the counter. The need for physician consultation ensures patient safety. The healthcare provider assesses contraindications and potential interactions before prescribing.

Patients should adhere to professional guidance. Self-medication or acquisition through non-regulated channels poses significant risks. Consultation ensures the correct therapeutic pathway and dosage for individual conditions.
