What is Intagra 100?

Intagra 100 is an allopathic medicine that is helpful to patients with erectile dysfunction. It is a situation in which males cannot gain a harder erection when having intercourse. Due to this, a person also suffers from major sexual problems like unwillingness to have intercourse (low libido) and declining sexual satisfaction levels. The medicine helps suppress the symptoms of erectile dysfunction temporarily. It will help a person have satisfactory intercourse.

The medicine is manufactured by Intas Pharmaceutical Ltd., which packs it in a strip of 4 tablets. Each tablet is diamond-shaped and blue in color, containing 100 mg of Sildenafil Citrate. It is the active pharmaceutical ingredient of the medicine that falls in the PDE type5 inhibitor class action of medicine.

Sildenafil is the oldest ingredient in this category, which takes 20-25 minutes on average to act inside the body. Once active, the salt will stay in that state for 4-5 hours on average. Also, people who want to consume Sildenafil require a prescription.

How does Intagra 100mg work?

The working of the Intagra 100mg is simple as its main task is to block the actions of PDE type5. It is a hormone released by the body to ensure that a person’s heart is safe under all circumstances. Whenever the body feels that there is some risk to the heart, PDE type5 is released inside the blood vessels where it blocks the release of cGMP. It is a vasodilator, and its blocking leads to contraction of blood vessels, leading to erectile dysfunction.

When a person consumes the medicine, Sildenafil enters the blood vessels and starts searching for PDE type5 to block its action. Soon, the cGMP levels in the blood vessels increase, dilating the blood vessels. Due to this, a person gets a harder erection when sexually aroused.

Dosage Requirement

The physician decides the dose of the medicine that a person needs to consume. They will check the levels of issues in your body and need to know the details about your medical history. It will first help them ensure the patient’s safety and then prescribe the medicine one or two per day.
