After administration of vardenafil orally disintegrating tablet to elderly (≥ 65 years) and young (18–45 years) patients with erectile dysfunction, mean vardenafil AUC was increased by 21 to 29%, respectively while mean Cmax was lower by 19% and 8%, respectively, in comparison to 10 mg vardenafil (film-coated tablets). In a study of healthy male volunteers (18–50 years), the mean Cmax and AUC of vardenafil from vardenafil orally disintegrating tablet were higher by 15% and 44%, respectively compared to 10 mg vardenafil film-coated tablets.Vardenafil was not found to accumulate in plasma when vardenafil orally disintegrating tablet was dosed daily over ten days.Effect of food: A high fat meal had no effect on vardenafil AUC and Tmax from vardenafil orally disintegrating tablet in healthy volunteers and reduced Cmax by 35%.

Vardenafil orally disintegrating tablet can be taken with or without food.Effect of water: When vardenafil orally disintegrating tablet was swallowed with water, the AUC of vardenafil was reduced by 29% and median Tmax was shortened by 60 minutes while Cmax was not affected. In clinical trials, dosing was done without water. Vardenafil orally disintegrating tablet should be taken without liquid.DistributionThe mean steady-state volume of distribution (Vss) for vardenafil is 208 L, indicating extensive tissue distribution. This protein binding is reversible and independent of total drug concentrations.Following a single oral dose of 20 mg vardenafil film-coated tablet in healthy volunteers, a mean of 0.00018% of the administered dose was obtained in semen 1.5 hours after dosing.MetabolismVardenafil is metabolized predominantly by the hepatic enzyme CYP3A4, with contribution from the CYP3A5 and CYP2C isoforms. Therefore, M1 accounts for approximately 7% of total pharmacologic activity.ExcretionThe mean terminal half-life of vardenafil in patients receiving vardenafil orally disintegrating tablets varied between about 4–6 hours. The elimination half-life of the metabolite M1 is between 3 to 5 hours. After oral administration, vardenafil is excreted as metabolites predominantly in the feces (approximately 91–95% of administered oral dose) and to a lesser extent in the urine (approximately 2–6% of administered oral dose). Vardenafil is a high clearance drug with a plasma clearance of 56.4 L/h following intravenous administration.Pharmacokinetics in Specific PopulationsPediatricsvardenafil orally disintegrating tablet is not indicated for use in pediatric patients. Vardenafil trials were not conducted in the pediatric population.GeriatricsVardenafil AUC and Cmax in elderly patients (65 years or older) taking vardenafil orally disintegrating tablets were increased by 39% and 21%, respectively, in comparison to patients aged 45 years and below [see Use in Specific Populations (8.5)].Hepatic ImpairmentIn volunteers with mild hepatic impairment (Child-Pugh A), the Cmax and AUC following a 10 mg vardenafil (film-coated tablets) dose were increased by 22% and 17%, respectively, compared to healthy control subjects.

]Renal ImpairmentIn volunteers with mild renal impairment (CLcr = 50–80 mL/min), the pharmacokinetics of vardenafil were similar to those observed in a control group with normal renal function. In the moderate (CLcr = 30–50 mL/min) or severe (CLcr <30 mL/min) renal impairment groups, the AUC of vardenafil was 20–30% higher compared to that observed in a control group with normal renal function (CLcr >80 mL/min).

Vardenafil pharmacokinetics have not been evaluated in patients requiring renal dialysis [see Dosage and Administration (2.3),Warnings and Precautions (5.9),and Use in Specific Populations (8.7)] . Penile erection is a hemodynamic process initiated by the relaxation of smooth muscle in the corpus cavernosum and its associated arterioles. The pharmacodynamic studies described below were conducted using vardenafil film-coated tablets. In a clinical pharmacology study of patients with erectile dysfunction, single doses of vardenafil 20 mg film-coated tablets caused a mean maximum decrease in supine blood pressure of 7 mmHg systolic and 8 mmHg diastolic (compared to placebo), accompanied by a mean levitra now online maximum increase of heart rate of 4 beats per minute.

Effects on Blood Pressure and Heart Rate when Vardenafil is Combined with Nitrates A study was conducted in which the blood pressure and heart rate response to 0.4 mg nitroglycerin (NTG) sublingually was evaluated in 18 healthy subjects following pretreatment with vardenafil 20 mg film-coated tablets at various times before NTG administration. Additional blood pressure and heart rate changes were not detected when vardenafil 20 mg film-coated tablet was dosed 24 hours before NTG (see Figure 1). Figure 1: Placebo-subtracted point estimates (with 90% CI) of mean maximal blood pressure and heart rate effects of pre-dosing with vardenafil 20 mg at 24, 8, 4, and 1 hour before 0.4 mg NTG sublingually Because the disease state of patients requiring nitrate therapy is anticipated to increase the likelihood of hypotension, the use of vardenafil by patients on nitrate therapy or on nitric oxide donors is contraindicated [see Contraindications (4.1)].
