While most adverse effects are mild, some may be more serious.

Conditions treated by Levitra and Cialis

Although the drug received the support of an FDA advisory panel in April 2000 (as reported by heartwire ), TAP Pharmaceuticals withdrew apomorphine's new drug application soon after, due to concerns that it caused fainting spells. It resubmitted the drug late last year after further studies. Cite this: FDA approves new erectile dysfunction drug - Medscape - Aug 20, 2003. Vardenafil (generic for Levitra®) improves erectile dysfunction (ED) by making it easier for blood to flow to the penis.

It’s one of several medications for ED. Others include sildenafil (the active ingredient in Viagra), tadalafil (Cialis), and avanafil (Stendra).

• Levitra works by blocking PDE5 enzyme, enhancing erectile response.
• Patients should not engage in strenuous activity immediately after taking Levitra.
• It is often prescribed when other ED treatments have failed or are unsuitable.
• Levitra has a rapid onset, with effects usually seen within 30-60 minutes.
• The medication is available in various dosages to tailor treatment.
• Alcohol and high-fat foods can impair the absorption of Levitra.
• Women should not take Levitra as it is not approved for female use.
• Regular follow-up with a healthcare provider helps monitor treatment efficacy.

Vardenafil is available as 2.5mg, 5mg, 10mg, or 20mg (milligrams) oral tablets. It’s also sold as disintegrating tablets under the brand name Staxyn®.

What is Levitra?

The median time to reach Cmax in a fasted stated was 1.5 hours (range: 45 minutes to 2.5 hours). High fat meals had no effect on vardenafil AUC or Tmax in healthy volunteers, but reduced the Cmax by 35%. When the orally disintegrating vardenafil tablets were administered with water, the vardenafil AUC was reduced by 29% and the median Tmax was shortened by 60 minutes, while Cmax was not affected. Vardenafil is not indicated for use in females. There are no adequate and well-controlled trials of vardenafil in humans during pregnancy.

How should I store vardenafil?

In animal reproduction studies, no adverse developmental outcomes were observed during organogenesis at exposures for unbound vardenafil and its major metabolite at 100 and 29 times, respectively, the maximum recommended human dose (MRHD) of 20 mg. Vardenafil is not indicated for use in females and is therefore not recommended during breast-feeding. There is no information on the presence of vardenafil and its major metabolite in human milk, the effects on the breast-fed infant, or the effects on milk production. Vardenafil is excreted into the milk of lactating rats at concentrations approximately 10-fold greater than found in the plasma; following a single oral dose of 3 mg/kg, 3.3% of the administered dose was excreted into the milk within 24 hours. [Levitra (oral dispersible tablet)--an innovative drug for the treatment of patients with erectile dysfunction]. Vardenafil pills are designed to be taken about an hour before sexual activity.

Proper Use

Sildenafil, another PDE inhibitor, has a lower selectivity for PDE5 versus PDE6 and is associated with abnormalities related to color vision with higher doses or plasma concentrations of the drug. The mean steady-state volume of distribution is 208L, indicating extensive distribution throughout the body. Vardenafil and its major metabolite (M1) are highly bound to plasma proteins (approximately 95% for parent drug and M1). Vardenafil is metabolized predominantly in the liver by CYP3A4 (there is some contribution by CYP3A5 and CYP2C isoforms). The major metabolite M1 is the result of desethylation at the piperazine moiety of vardenafil and is further metabolized.

Key Takeaways

M1 has phosphodiesterase selectivity similar to that of vardenafil and an in vitro inhibitory potency for phosphodiesterase 5 (PDE5) that is 28% of that of vardenafil. M1 accounts for about 7% of the total pharmacological activity. Vardenafil is excreted as metabolites predominantly in the feces (approximately 91% to 95% of an oral dose) and to a lesser extent in the urine (about 2% to 6% of an oral dose). The elimination half-life of vardenafil and M1 is about 4 to 5 hours with the use of the film-coated tablets. The elimination half-life of vardenafil is 4 to 6 hours and the elimination half-life of MI is 3 to 5 hours with the use of the orally disintegrating tablets. You can take it with or without food, but it might work more quickly if you take it on an empty stomach.

Frequently asked questions about Levitra vs. Viagra

Affected Cytochrome P450 (CYP450) isoenzymes and drug transporters: CYP3A4, P-glycoprotein (P-gp)Vardenafil is primarily a substrate of CYP3A4. Concomitant use of vardenafil with moderate or strong CYP3A4 inhibitors may require a reduction in vardenafil dosage to reduce the risk of adverse effects. In vitro data suggest that vardenafil may inhibit P-gp at therapeutic doses. While concomitant use of vardenafil did not significantly increase plasma concentrations of digoxin (a P-gp substrate), the effect of vardenafil on plasma concentrations of P-gp substrates more sensitive than digoxin (e.g., dabigatran) is unknown. Oral film-coated tablets:Vardenafil is rapidly absorbed with absolute bioavailability of approximately 15%.

How effective are vardenafil and tadalafil for erectile dysfunction?

In healthy volunteers, peak plasma concentrations (Cmax) following administration of a single 20 mg oral tablet dose are usually reached between 30 minutes and 2 hours (median 60 minutes) in the fasted state. High-fat meals reduced Cmax by 18% to 50%. The onset of action is within 1 hour of administration.Orally disintegrating tablets:The orally disintegrating vardenafil tablets provide a higher systemic exposure than the film-coated tablets. In a study of patients with erectile dysfunction, the mean AUC was increased by 21% to 29% and the mean Cmax was decreased by 19% in geriatric patients and 8% in younger patients (18 to 45 years) as compared to the 10 mg film-coated tablets. In a study of healthy male volunteers (18 to 50 years), the mean Cmax was 15% higher and the mean AUC was 44% higher compared to the 10 mg film-coated tablets. The effects can last five to seven hours, making vardenafil a great choice for single-night use compared to longer-acting ED medications. Our blog on Levitra versus Viagra compares vardenafil to another single-night-use ED medication.

Is it dangerous to use Levitra with other nitrates?

The arsenal of professionals providing assistance to men with erectile dysfunction includes a new, mouth dissolving dosage form of the vardenafil--levitra ODT. This form is effective, safe, and has a higher bioavailability as compared to vardenafil in the form of coated tablets. POTENT I and POTENT II studies revealed that levitra ODT equally successfully corrects erectile dysfunction in men younger and older than 65 years regardless of concomitant diseases and metabolic disorders: hypertension, diabetes, dyslipidemia. In addition, it was found that this drug helped to successfully carry out sexual intercourse in the first 15 minutes after dosing in 62.5% of patients. This allows to widely recommend levitra ODT for the treatment of erectile dysfunction in young men and older men.

Dosage for ED

Washington, DC - The FDA gave approval yesterday to vardenafil (Levitra®, Bayer and Glaxo Smith Kline), an oral erectile-dysfunction drug cost levitra costco that works through the same mechanism as sildenafil (Viagra®, Pfizer). Like sildenafil, vardenafil can seriously affect blood pressure and should not be taken by those on alpha blockers or nitrates. The recommended dose is 10 mg taken one hour before sexual activity, with 20-, 5.0-, and 2.5-mg doses available. Vardenafil is a phosphodiesterase inhibitor and, like sildenafil, is strongly contraindicated if patients are taking nitrates (nitroglycerin tablets or patches) or alpha blockers, due to the possibility of a steep drop in blood pressure. Patients with QT prolongation are also advised not to take the drug, as there is a possibility of abnormal heart rhythm in these patients. Serious side effects from vardenafil and other ED medications are uncommon, only affecting a small percentage of men who use them.

However, they can still happen, and some may require urgent medical attention when they occur. Let’s go over the more serious potential side effects and drug interactions of vardenafil, including those that call for medical help. Priapism is a painful, prolonged erection lasting four hours or longer.

• Levitra can be part of a comprehensive approach to managing erectile dysfunction.
• Dietary supplements claiming to be similar to Levitra are not FDA-approved.
• If an erection lasts longer than 4 hours, seek emergency medical care.
• Levitra may be less effective in men with severe diabetes or cardiovascular disease.
• Patients should avoid grapefruit or grapefruit juice while on Levitra.
• Precautions include avoiding driving or operating machinery after taking Levitra.
• Individuals with hereditary eye diseases should consult a doctor before use.
• Levitra may cause a drop in blood pressure, especially when combined with other meds.

It happens when blood can’t flow out of the penis after an erection.

Warnings & Precautions

Eli Lilly & Co and Icos Corporation intend to introduce tadalafil (Cialis®), another phosphodiesterase inhibitor, to the US market later this year. Tadalafil and vardenafil have both been approved in Europe. Currently, there have been no head-to-head trials comparing effectiveness of the three drugs. A fourth oral erectile-dysfunction drug, apomorphine (Uprima®, TAP Pharmaceuticals), has been approved in Europe, and TAP Pharmaceuticals applied to the FDA for its approval at the end of 2002. It is a dopamine receptor agonist and works through an entirely different mechanism. When untreated, priapism can damage erectile tissues inside the penis.

The FDA warns that men whose underlying cardiovascular status makes sexual activity inadvisable should not take vardenafil. Patients who have suffered an MI or stroke within the last six months or have hypotension or hypertension, unstable angina, severe liver impairment, end-stage renal disease requiring dialysis, or retinitis pigmentosa should not take the drug. "Today's approval of Levitra means there is now an important alternative in the treatment of erectile dysfunction," said Colin J Foster, president, Bayer Pharmaceuticals Corporation, in a press release. The drug will be comarketed by Glaxo Smith Kline and Bayer, and Bloomberg News reports packaging will feature the "Levitra flame" to help distinguish the round orange pills from Viagra's now-famous blue diamond-shaped ones. Both drugs are likely to soon have a third competitor stateside. Still, priapism is a serious medical issue. If you get an erection that lasts four or more hours after using vardenafil, seek medical assistance immediately.
