Vardenafil tablets are oral solid dosage forms containing vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor used for the treatment of erectile dysfunction.

Clinically, vardenafil improves penile hemodynamics by enhancing cyclic guanosine monophosphate (cGMP) signaling, thereby facilitating smooth-muscle relaxation and engorgement of the corpus cavernosum during sexual stimulation. Pharmacokinetic data derived from clinical and post-marketing studies show that orally administered vardenafil is rapidly absorbed, achieving peak plasma concentrations within 30-120 minutes, with an absolute bioavailability near 15 %.

First-pass hepatic metabolism via cytochrome P450 3A4 and, to a lesser extent, CYP 2C isoenzymes, accounts for the relatively modest systemic exposure compared with intravenous dosing. The terminal elimination half-life is approximately 4-6 hours, supporting once-daily on-demand administration rather than continuous dosing. In healthy volunteers, food high in fat delays but does not meaningfully diminish the extent of absorption; however, grapefruit products may significantly alter plasma levels through metabolic inhibition (see Interactions). Because vardenafil undergoes high plasma-protein binding (~95 %), clinically significant displacement interactions are theoretically possible but uncommon. For most adult males, the recommended on-demand oral dose is 10 mg administered approximately 60 minutes prior to anticipated sexual activity; however, patient-specific factors often prompt individualized regimens. Clinical experience supports initial titration downward to 5 mg in men ≥ 65 years or in those with moderate hepatic impairment (Child-Pugh B), and upward adjustment to 20 mg in younger, otherwise healthy men who exhibit inadequate response. Dosing frequency should not exceed one dose per 24-hour period to minimize cumulative exposure and adverse events.

Potential Interactions: What to Watch Out For:

For most adult males, the recommended on-demand oral dose is 10 mg administered approximately 60 minutes prior to anticipated sexual activity; however, patient-specific factors often prompt individualized regimens. Clinical experience supports initial titration downward to 5 mg in men ≥ 65 years or in those with moderate hepatic impairment (Child-Pugh B), and upward adjustment to 20 mg in younger, otherwise healthy men who exhibit inadequate response. Dosing frequency should not exceed one dose per 24-hour period to minimize cumulative exposure and adverse events. Patients receiving potent CYP3A4 inhibitors may require maximum doses of 2.5-5 mg no more than once in 72 hours. The erectile response is a neurovascular event initiated by parasympathetic-mediated nitric oxide (NO) release from cavernous nerve terminals and endothelial cells.

Prevention & Wellness

NO stimulates guanylate cyclase, increasing intracellular cGMP, which in turn lowers intracellular calcium and relaxes trabecular smooth muscle. PDE5 terminates this signal by hydrolyzing cGMP to its inactive 5′ monophosphate. Vardenafil binds selectively and reversibly to the catalytic site of PDE5, raising cGMP concentrations and amplifying the natural erectile cascade in the presence of vardenafil vilitra 60 mg sexual arousal. In vitro affinity profiling demonstrates that vardenafil exhibits a 10- to 20-fold greater potency against PDE5 than sildenafil and maintains over 1000-fold selectivity versus other cyclic nucleotide phosphodiesterases, including the cardiac isoenzyme PDE3 and retinal PDE6. This selectivity profile reduces the likelihood of off-target hemodynamic or visual disturbances, although minor, transient alterations in color discrimination have been documented.

These interactions stabilize the inhibitor-enzyme complex, yielding an inhibitory constant (K_i) in the low nanomolar range. Following oral ingestion of a 20 mg tablet, mean vardenafil C_max approximates 20 ng mL⁻¹, with systemic exposure proportional across a 5-20 mg dose span. Metabolic clearance is dominated by oxidative N-dealkylation and ring hydroxylation, producing an active metabolite (M1) that retains ~28 % of parent potency but constitutes less than 7 % of the circulating molar fraction. Because PDE5 predominates in erectile tissue, systemic vasodilatory effects are typically modest at therapeutic doses. Nonetheless, vardenafil can synergize with exogenous NO donors, precipitating pronounced hypotension if nitrates or soluble guanylate-cyclase stimulators are co-administered. Absolute contraindications include concurrent use of organic nitrates (e.g., nitroglycerin, isosorbide dinitrate) in any form. Co-administration may lead to severe, potentially life-threatening hypotension owing to additive increases in cGMP-mediated vasodilation. Similarly, patients receiving riociguat, a soluble guanylate-cyclase stimulator, should avoid vardenafil because the combination can produce profound systemic blood-pressure reductions unresponsive to vasopressors. Prescribers must inquire specifically about intermittent nitrate use for angina prior to initiating therapy. Individuals with inherited degenerative retinal disorders such as retinitis pigmentosa, although representing less than one percent of the population, were excluded from pivotal trials; theoretical PDE6 cross-reactivity raises concerns about exacerbating photoreceptor degeneration. Vardenafil should also be withheld in patients with known hypersensitivity to the drug or its excipients.

Proper Use

For example, concomitant ketoconazole 400 mg once daily increased vardenafil area under the curve (AUC) nearly ten-fold; under such circumstances, dosing should not exceed 2.5 mg in 24 hours. Combined use with α-adrenergic blockers (e.g., doxazosin, terazosin) may potentiate orthostatic hypotension due to overlapping vasodilatory effects. Titrate the α-blocker to a stable maintenance dose and ensure hemodynamic stability before introducing vardenafil at the lowest feasible dose. Clinical pharmacology trials evaluating co-administration with tamsulosin 0.4 mg daily demonstrated no clinically significant blood-pressure reductions when vardenafil was given two hours after the α-blocker, underscoring the importance of temporal separation and dose adjustment. Additional interactions include moderate CYP3A4 inducers (e.g., rifampin, carbamazepine), which can lower systemic exposure, potentially requiring dosage escalation if clinically justified.

How does vardenafil work (mechanism of action)?

Grapefruit juice inhibits enteric CYP3A4 and may unpredictably increase vardenafil bioavailability; patients should be advised to avoid large quantities or to maintain consistent intake patterns to minimize variability. Pharmacodynamic synergy with other vasodilators, antihypertensives, or alcohol could accentuate blood-pressure reductions, warranting patient counseling on positional dizziness and syncope risk. In randomized controlled trials, the most frequently reported adverse reactions included headache (up to 15 %), facial flushing (10 %), nasal congestion (7 %), dyspepsia (4 %), and dizziness (2 %). These events were generally mild to moderate, transient, and self-limiting, correlating with peak plasma levels and attenuating upon repeated, intermittent use. Visual disturbances, predominantly a blue-green tinge or increased light sensitivity, occurred in ≤ 2% of subjects and resolved within hours of dosing cessation, consistent with transient PDE6 inhibition.

Although rare, priapism-painful erections persisting beyond four hours-has been associated with PDE5 inhibitors, including vardenafil. Post-marketing pharmacovigilance identified fewer than 1 case per 50,000 prescriptions, yet the potential for irreversible tissue ischemia necessitates prompt medical intervention for prolonged erections. Counsel patients to seek emergency care if tumescence exceeds four hours. Additional serious but uncommon adverse events comprise sudden sensorineural hearing loss, non-arteritic anterior ischemic optic neuropathy, and myocardial infarction in predisposed individuals; establishing causality is challenging due to confounding vascular risk factors inherent to the target population. Cardiac electrophysiology investigations have shown small QTc prolongations that generally lack clinical consequence but underscore the need to avoid concomitant class IA or III anti-arrhythmic agents. Electrocardiographic studies revealed small, dose-dependent increases in QTc (approximately 4-6 ms) at supratherapeutic exposures; consequently, vardenafil is contraindicated in men taking class IA or class III anti-arrhythmic agents (e.g., quinidine, procainamide, amiodarone, sotalol) or in those with congenital long-QT syndrome. Additional caution is warranted following recent (< 6 months) myocardial infarction, stroke, or life-threatening arrhythmia, and in patients with uncontrolled hypertension (≥ 170/100 mm Hg), severe hypotension (< 90/50 mm Hg), or severe hepatic impairment (Child-Pugh C). Data from pooled cardiovascular safety analyses indicate that men with stable coronary artery disease who are not taking nitrates do not experience an increased incidence of major adverse cardiac events when treated with PDE5 inhibitors; however, clinical judgment should prevail for each patient’s risk-benefit assessment. Pharmacokinetic interactions largely stem from vardenafil’s metabolism by CYP3A4. For example, concomitant ketoconazole 400 mg once daily increased vardenafil area under the curve (AUC) nearly ten-fold; under such circumstances, dosing should not exceed 2.5 mg in 24 hours.
