LEVITRA is formulated as orange, round, film-coated tablets with “BAYER” cross debossed on one side and “2.5”, “5”, “10”, and “20” on the other side corresponding to 2.5 mg, 5 mg, 10 mg, and 20 mg of vardenafil, respectively. The most abundant PDE in the human corpus cavernosum is the cGMP-specific phosphodiesterase type 5 (PDE5); therefore, the inhibition of PDE5 enhances erectile function by increasing the amount of cGMP. The pharmacokinetics of vardenafil are approximately dose proportional over the recommended dose range.

Vardenafil is eliminated predominantly by hepatic metabolism, mainly by CYP3A4 and to a minor extent, CYP2C isoforms.
5.3 Risk of Priapism
As a result, it helps prolong an erection. Vardenafil is available in tablets of 2.5 milligrams (mg), 5 mg, 10 mg, and 20 mg. The first dose is normally 10 mg. A 10-mg dose of vardenafil is approximately equivalent to 50 mg of sildenafil, or Viagra. This is because the chemical composition of vardenafil is different from that of sildenafil.
Who should not take vardenafil?
Vardenafil is taken 25 to 60 minutes before sex. The effect lasts for up to 5 hours. A vidalista 20mg uk maximum of one tablet can be used every 24 hours. Orodispersible tablets must be left to dissolve on the tongue before swallowing. They should not be taken with any kind of drink.
Visual disturbances
The drug will not work unless the man is sexually aroused, so foreplay will normally be necessary. Vardenafil can be taken with or without food, but drinking alcohol is not advised, as it reduces the chance of getting an erection. Alcohol can also increase the risk of adverse effects. As with all medications, adverse effects and interactions can occur when using vardenafil. One in 10 men will experience headache. Concomitant use with potent CYP3A4 inhibitors such as ritonavir, indinavir, ketoconazole, as well as moderate CYP3A inhibitors such as erythromycin results in significant increases of plasma levels of vardenafil (see PRECAUTIONS, WARNINGS and DOSAGE AND ADMINISTRATION). Mean vardenafil plasma concentrations measured after the administration of a single oral dose of 20 mg to healthy male volunteers are depicted in Figure 1. Figure 1: Plasma Vardenafil Concentration (Mean ± SD) Curve for a Single 20 mg LEVITRA Dose Vardenafil is rapidly absorbed with absolute bioavailability of approximately 15%. Maximum observed plasma concentrations after a single 20 mg dose in healthy volunteers are usually reached between 30 minutes and 2 hours (median 60 minutes) after oral dosing in the fasted state. Two food-effect studies were conducted which showed that high-fat meals caused a reduction in Cmax by 18%-50%. The 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 in healthy volunteers, a mean of 0.00018% of the administered dose was obtained in semen 1.5 hours after dosing.

Vardenafil 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.
8.5 Geriatric Use
In most cases, these disappear within a few hours. ringing in the ears, or sudden hearing loss swelling in the ankles, hands, or feet The patient should stop using vardenafil if these occur. This can lead to hives, difficulty breathing, and swelling of the face, tongue, and throat. If these symptoms appear, it should be treated as a medical emergency. Very rare side effects may include priapism, when an erection lasts longer than 4 hours.
Treatment & Diagnosis
If an erection lasts too long, the individual should seek medical attention. Visual disturbances can happen when blood pressure drops in the eye. The individual may see a blue tinge to objects, and they may have difficulty distinguishing between the colors green and blue. Very rarely, there may be a sudden deterioration in vision in one or both eyes. This can indicate a heart condition, an existing eye problem, high cholesterol, diabetes, or hypertension.
What are the side effects of vardenafil?
If any sudden loss of vision occurs, the individual should stop taking the medication and seek medical help immediately. Vision problems are most likely in patients with other conditions, such as heart or coronary artery disease, diabetes, and high cholesterol. Vision problems are more likely to happen if the person smokes, or if they are aged over 50 years. Using vardenafil with some other drugs can lead to serious adverse effects. a potentially dangerous drop in blood pressure, or hypotension There is also a risk of stroke and heart attack. 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. 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). Pediatrics: Vardenafil trials were not conducted in the pediatric population. Geriatrics: 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 (see PRECAUTIONS, Geriatric Use and DOSAGE AND ADMINISTRATION).

Consequently, a lower starting dose of LEVITRA (5 mg) in patients ≥65 years of age should be considered. Renal Insufficiency: In 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 PRECAUTIONS, Renal Insufficiency, and DOSAGE AND ADMINISTRATION).

8.1 Pregnancy
During a penile erection, the penis fills with blood. The blood vessels that supply the penis with blood expand, or dilate, and the vessels that take blood away from the penis contract. The two large chambers in the penis, known as the corpus cavernosa, fill with blood. As the blood accumulates in the penis, an erection results. Vardenafil belongs to a class of drugs called phosphodiesterase type-5 (PDE5) inhibitors.
What is vardenafil, and what is it used for?
A PDE5 inhibitor stops PDE5 from constricting the arteries. By relaxing the arteries, vardenafil enhances blood flow when a man is sexually aroused. The active ingredient works on the chain of reactions within the penis during arousal. When a male is sexually aroused, nitric oxide is released into his penis, and this triggers a chain of reactions. This causes an enzyme, guanylate cyclase, to produce cyclic guanosine monophosphate (cGMP).
Dosage Modifications
cGMP regulates the contraction and dilation, or expansion, of blood vessels that carry blood to and from the penis. The chemical reaction causes the vessels that supply the penis to dilate, while those removing blood from the penis contract. Phosphodiesterase-5 (PDE5), another enzyme breaks down or destroys cGMP. When cGMP is destroyed, the blood vessels return to their normal size, effectively ending the erection. In this way, it allows cGMP to work for longer.
