Valif 20mg Tablet

What are The Uses of Valif 20mg Tablet?

1.Erectile Dysfunction (ED- General or Mixed)

ED refers to the inability of an adult human male to procure or sustain an erection for a sufficient amount of time. Generally, ED can manifest due to several reasons such as underlying physical conditions, psychological issues, medical interventions, etc. Valif 20 mg tablet argets the core source of the condition- insufficient blood circulation. It facilitates vasodilation, and improves the blood flow to the penis, thus restoring the penile function.

2.Erectile Dysfunction in Elderly Patients (over 65 years)

In geriatric individuals, ED generally occurs due to reduced endothelial function, decreased testosterone, and slow penile hemodynamic response. In such patients, Valif 20mg tablet enhances the body’s natural functioning, which improves sexual function. However, for such individuals, a lower dose of Vardenafil (starting with 5 mg) is generally prescribed.

3.Erectile Dysfunction in Patients with Diabetes Mellitus

Diabetes affects the endothelial functioning, which is an important component in the penile functioning. In such cases, Valif 20mg tablet supports the natural pathway of erection formation, and increases its efficiency. As a result, even if the biochemical machinery is reduced in diabetic patients, their physiological output becomes sufficient to sustain an erection.

What are The Dosage Guidelines?

ED – General Adult Population

• Recommended dose: 1 tablet of Valif 20 mg (20 mg of Vardenafil) taken orally about 60 minutes before sexual activity. 
• Maximum limit: 20 mg of Vardenafil per day (1 tablet of Valif 20 mg).
• Important clinical information: Not more than one dose in 24 hours. Initial therapy may begin with 10 mg of Vardenafil depending on the patient’s profile. The dose may be adjusted between 5–20 mg based on efficacy and tolerability.

ED – Elderly Patients (over 65 years)

• Recommended dose:  5 mg of Vardenafil taken orally before sexual activity 
• Maximum limit:
  20 mg of Vardenafil per day (1 tablet of Valif 20 mg).
• Important clinical information: Initiate at 5 mg due to higher plasma concentrations in elderly; titrate cautiously. The dosage may be increased to 1 tablet of Valif 20 mg (20 mg of Vardenafil) if tolerated and clinically required.

ED – Patients on Moderate CYP3A4 Inhibitors (e.g., erythromycin)

• Recommended dose: 5 mg of Vardenafil taken orally before sexual activity. 
• Maximum limit:5 mg of Vardenafil per day when used with moderate CYP3A4 inhibitors.
• Important clinical information: Strong CYP3A4 inhibitors are contraindicated with Varif 20 mg. In combination with moderate inhibitors, maximum recommended dose is 5 mg within 24 hours. Do not exceed 1 tablet of Valif 20 mg (20 mg of Vardenafil), though lower dosing is preferred.

How Does Valif 20mg Tablet Work?

The active component of Valif 20mg tablet  is Vardenafil, a PDE-5 inhibitor medication that targets the NO-cGMP pathway.This pathway is involved in blood circulation in several tissues and organs.

Normally, an external trigger (such as sexual stimulation or nervous system signaling) activates the NO-cGMP pathway. Nitric oxide (NO) is released by the nerve endings or endothelial tissues in response to these stimuli, and it quickly permeates the surrounding tissues. It causes guanylate cyclase, an enzyme that transforms guanosine triphosphate (GTP) into guanosine monophosphate (cGMP) molecules, to become active.

As secondary chemical messengers, the cGMP molecules control other physiological reactions in the region. The cGMP molecules support the entry of potassium molecules into the cells and lower intracellular calcium levels. This promotes vasodilation, also known as the widening of blood vessels. As a result, the blood flow in these blood vessels is increased. Additionally, it also promotes smooth muscle tissue relaxation.

These reactions are necessary for the physiological responses to external stimuli to operate normally. These reactions are essential for the development of an erection, the operation of veins and arteries, and other metabolic processes.

After a sufficient concentration of cGMPs is achieved, an enzyme known as phosphodiesterase type-5 (PDE-5) is activated. This enzyme is constitutively present in the tissues where the NO-cGMP pathway is generally functional. It is released via a feedback mechanism when cGMP concentrations are high.

Any physiological effects caused by the cGMP molecules are reversed when the PDE-5 breaks them down. This results in smooth muscle toning and blood vessel constriction. To return the body to its typical resting state, these responses are necessary. The benefits, like vasodilation and relaxed tissues, would last forever if the PDE-5 enzyme were absent. These may lead to abnormalities like a protracted erection or severe pulmonary artery dilatation.

The effects of PDE-5, however, may be excessive or premature in certain people. Because of this, the cGMP molecules are unable to perform their roles for a sufficient measure. This anomaly in the vascular and the biochemical pathway results in conditions such as pulmonary arterial hypertension and erectile dysfunction.

Valif 20mg tablet promoted the formation of an adequate concentration of cGMP molecules in the tissues as it specifically targets the PDE-5 enzyme. This leads to the relaxation of the smooth muscle tissues and adequate blood flow in the blood vessels. As a result, Valif 20 mg tablet is a useful drug for treating conditions that arise from compromised PDE-5 enzyme function.

Frequently Asked Questions

Q. How long does Valif 20mg tablet ake to work?

Valif 20 mg takes approximately 30-60 mins to become effective. This timing depends on several factors such as individual metabolic rate, meal consumption, etc. 

Q. Can Valif 20 mg be taken daily?

There is a high concentration of Vardenafil in Valif 20mg tablet. Hence, this medication must only be consumed on an on-demand basis, unless instructed otherwise by a healthcare professional.

Q. Is Valif 20 mg safe for heart patients?

In patients with cardiovascular diseases, Valif 20mg tablet must be administered very carefully, especially if these patients are undergoing nitrates therapy. For such patients, there must be regular monitoring of cardiovascular parameters such as heart function, blood pressure, etc.

Q. Does Valif 20mg tablet increase sexual libido spontaneously?

No. Valif 20 mg works by enhancing the body’s natural biochemical pathway responsible for erection formation. This pathway cannot be activated in absence of an external trigger. Hence, Valif 20 mg cannot spontaneously increase sexual libido.

Q. What happens if I take more than one dose of Valif 20mg tablet in 24 hours?

This will constitute an overdose and can lead to several side effects such as severe headache, low blood pressure, visual disturbances, and priapism. In such cases, immediate medical attention is required.
