Levitra® (vardenafil) is an oral medication for ED that starts working in about 60 minutes and lasts up to five hours.
Renal Dose Adjustments
The total time to 1 mm or greater ST-segment depression was similar to placebo in both the 10 mg and the 20 mg vardenafil groups (10 mg LEVITRA vs. placebo: 380±108 and 334±108 seconds; 20 mg vardenafil vs. placebo: 364±101 and 366±105 seconds, respectively). Single oral doses of phosphodiesterase inhibitors have demonstrated transient dose- related impairment of color discrimination (blue/green) using the Farnsworth-Munsell 100-hue test and reductions in electroretinogram (ERG) b-wave amplitudes, with peak fildena ct effects near the time of peak plasma levels. In a single dose study in 25 normal males, vardenafil 40 mg, twice the maximum daily recommended dose, did not alter visual acuity, intraocular pressure, fundoscopic and slit lamp findings.
Usual Geriatric Dose for:
In another double blind, placebo controlled clinical trial, at least 15 doses of 20 mg vardenafil were administered over 8 weeks versus placebo to 52 males. There was no effect on sperm motility or morphology after single 20 mg oral doses of vardenafil in healthy volunteers. Absorption: Vardenafil is rapidly absorbed with absolute bioavailability of approximately 15%. Two food-effect studies were conducted which showed that high-fat meals caused a reduction in Cmax by 18%-50%. Distribution: The mean steady-state volume of distribution (Vss) for vardenafil is 208 L, indicating extensive tissue distribution.
Biochem/physiol Actions
Metabolism: Vardenafil is metabolized predominantly by the hepatic enzyme CYP3A4, with contribution from the CYP3A5 and CYP2C isoforms. Elimination: The total body clearance of vardenafil is 56 L/h, and the terminal half-life of vardenafil and its primary metabolite (M1) is approximately 4-5 hours. Pediatrics: Vardenafil is not indicated for use in pediatric patients. Geriatric: In a healthy volunteer study of elderly males (≥65 years) and younger males (18-45 years), mean Cmax and AUC were 34% and 52% higher, respectively, in the elderly males. Hepatic Impairment: In volunteers with mild hepatic impairment (Child-Pugh A), the Cmax and AUC following a 10 mg vardenafil dose were increased by 22% and 17%, respectively, compared to healthy control subjects. Levitra® is a brand-name medication that contains the active ingredient vardenafil, which is used to treat erectile dysfunction (ED) by increasing blood flow to the penis during sexual stimulation.

In volunteers with moderate hepatic impairment (Child- Pugh B), the Cmax and AUC following a 10 mg vardenafil dose were increased by 130% and 160%, respectively, compared to healthy control subjects. Renal Impairment: In male volunteers with ClCr= 50-80 mL/min, the pharmacokinetics of vardenafil were similar to those observed in a control group with ClCr >80 mL/min. In male volunteers with ClCr = 30-50 mL/min or ClCr <30 mL/min renal impairment groups, the AUC of vardenafil was 20-30% higher compared to that observed in a control group with ClCr >80 mL/min). Advise patients sex with tablet of the contraindication of vardenafil with regular and/or intermittent use of organic nitrates. Patients should be counseled that concomitant use of vardenafil with nitrates could cause blood pressure to suddenly drop to an unsafe level, resulting in dizziness, syncope, or even heart attack or stroke.
What are the most common side effects of vardenafil?
Inform patients of the potential cardiac risk of sexual activity for patients with preexisting cardiovascular risk factors. Inform patients that in some patients concomitant use of PDE5 inhibitors, including vardenafil, with alpha-blockers can lower blood pressure significantly leading to symptomatic hypotension (for example, fainting). Patients prescribed vardenafil who are taking alpha-blockers should be started on the lowest recommended starting dose. Patients should be advised to contact the prescribing physician if other anti-hypertensive drugs or new medications that may interact with vardenafil are prescribed by another healthcare provider. Discuss with patients the appropriate use of vardenafil and its anticipated benefits.

Inform patients of the increased risk of NAION in individuals who have already experienced NAION in one eye and discuss the increased risk of NAION among the general population in patients with a "crowded" optic disc, although evidence is insufficient to support screening of prospective users of PDE5 inhibitor, including vardenafil, for this uncommon condition.

What is the most important information I should know about vardenafil?
The 80 mg dose of vardenafil (four times the highest recommended dose) was chosen because this dose yields plasma concentrations covering those observed upon co-administration of a low-dose of vardenafil (5 mg) and 600 mg BID of ritonavir. In this study, the mean increase in heart rate associated with a 10 mg dose of vardenafil compared to placebo was 5 beats/minute and with an 80 mg dose the mean increase was 6 beats/minute. Therapeutic and supratherapeutic doses of vardenafil and the active control moxifloxacin produced similar increases in QTc interval. The clinical impact of these QTc changes is unknown. In a separate post-marketing study of 44 healthy volunteers, single doses of 10 mg vardenafil resulted in a placebo-subtracted mean change from baseline of QTcF (Fridericia correction) of 5 msec (90% CI: 2,8).
General adverse events
Single doses of gatifloxacin 400 mg resulted in a placebo-subtracted mean change from baseline QTcF of 4 msec (90% CI: 1,7). When vardenafil 10 mg and gatifloxacin 400 mg were co-administered, the mean QTcF change from baseline was additive when compared to either drug alone and produced a mean QTcF change of 9 msec from baseline (90% CI: 6,11). The clinical impact of these QT changes is unknown. The patient population included men aged 40-80 years with stable exercise- induced angina documented by at least one of the following: 1) prior history of myocardial infarction (MI), coronary artery bypass graft (CABG), percutaneous transluminal coronary angioplasty (PTCA), or stenting (not within 6 months); 2) positive coronary angiogram showing at least 60% narrowing of the diameter of at least one major coronary artery; or 3) a positive stress echocardiogram or stress nuclear perfusion study. Results of these studies showed that vardenafil did not alter the total treadmill exercise time compared to placebo (10 mg vardenafil vs.

placebo: 433±109 and 426±105 seconds, respectively; 20 mg vardenafil vs. placebo: 414±114 and 411±124 seconds, respectively). The total time to angina was not altered by vardenafil when compared to placebo (10 mg vardenafil vs. placebo: 291±123 and 292±110 seconds; 20 mg vardenafil vs. placebo: 354±137 and 347±143 seconds, respectively).
