What is Sildenafil?

Sildenafil is highly effective for erectile dysfunction (ED), pulmonary arterial hypertension (PAH), and other conditions related to blood flow. It is also known as a phosphodiesterase type 5 (PDE5) inhibitor.

How does Sildenafil work?

Sildenafil increases blood flow to the penis to help a man easily achieve and maintain an erection. This efficacy is due to inhibiting the action of the PDE5 enzyme, which breaks down cyclic guanosine monophosphate (cGMP), a molecule that relaxes the smooth muscle in the penis and increases blood flow.

 Let’s understand the detailed working mechanism.

 When a man is sexually stimulated, the release of Nitric Oxide (NO) causes an increase in cGMP levels in the penis. This leads to the relaxation of smooth muscle in the corpus cavernosum. By inhibiting the action of PDE5, Sildenafil helps to maintain high levels of cGMP, which promotes the relaxation of smooth muscle and increases blood flow to the penis.

Sildenafil Dosage

You can buy Sildenafil in different dosages. However, the ideal dose for you can be evaluated by your doctor depending on your medical condition and other factors.

 The standard dose for ED is 50 mg. You need to take it about 1 hour before sexual activity. But this can be adjusted up or down depending on your individual needs.

Sildenafil is available in the following dosages.

25 mg: This low dose is often prescribed for men on secondary medications that may interact with Sildenafil. It is also ideal for older men, patients with mild ED, or men with other medical conditions that may increase their risk of side effects. It can also be prescribed for men who are older or have mild ED.

50 mg: This is the standard dose for most men with ED. You have to take it 1 hour before sexual activity and can adjust the dose based on efficacy and any side effects.

100 mg: This is the highest dose of Sildenafil available. If your case does not respond well to lower doses, doctors may prescribe you 100mg. But, it is also associated with a higher risk of side effects. Thus, before you buy Sildenafil 100mg in UK, consult your doctor first.

How to Take Sildenafil Tablets?

Sildenafil tablets are usually taken by mouth about 1 hour before sexual activity. Here are the general guidelines for taking Sildenafil tablets:

  • Take Sildenafil exactly as prescribed by your doctor. Never take more or less than the prescribed amount.
  • Swallow the entite Sildenafil tablet without crushing, chewing, or breaking it.
  • Take it with or without food, but not with a high-fat meal. 
  • Do not take Sildenafil more than once a day.
  • Do not take Sildenafil more than once a day.
  •  It’s important to remember that Sildenafil will only work if you are sexually aroused. It won’t make you more sexually motivated.
  • If you experience side effects such as chest pain, dizziness, or vision changes, stop taking the medication and contact your doctor right away.

How does it take Sildenafil to work?

Sildenafil typically starts to work within 30 to 60 minutes after it is taken, although the onset of action can vary depending on a number of factors, such as the individual’s metabolism, whether it is taken with food and the dosage.

 Once taken, Sildenafil is absorbed into the bloodstream and begins to inhibit the action of the PDE5 enzyme, which increases the levels of cyclic guanosine monophosphate (cGMP) in the penis. This leads to the relaxation of smooth muscle in the corpus cavernosum, which promotes blood flow to the penis and helps to achieve and maintain an erection.

 It’s important to note that Sildenafil will only work if the person taking it is sexually aroused. It does not increase sexual desire, and sexual stimulation is necessary for the medication to be effective.

 The effects of Sildenafil can last for up to 4 to 5 hours after it is taken, although this can also vary depending on the individual. It’s important to follow your doctor’s instructions and not take more than the recommended dose, as this can increase the risk of side effects. Also, before you decide to buy Sildenafil in UK, consult your doctor for sure.
