Intagra 100 is a medication that contains 100 mg of Sildenafil Citrate, manufactured by Intas Pharmaceuticals Ltd. It is prescribed by doctors to patients suffering from erectile dysfunction. This condition is characterized by the inability of the patient to achieve a satisfactory erection for stimulation during sexual activity, leading to unsatisfying intercourse for both males and females.

The manufacturer packages Intagra 100 in strips, with each strip containing 4 diamond-shaped tablets. The tablets have a brilliant blue color, and each tablet consists of 100 mg of sildenafil citrate. Additionally, titanium dioxide is included as an opacifier for tablet film coatings.

Uses of Intagra 100

  • Erectile dysfunction is the first reason the physician prescribes the medicine to males. In this situation, the medicine helps in gaining a harder erection, which is important for having satisfactory intercourse.

How does Intagra 100 work?

The working of the Intagra 100 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.

  • Individuals with heart conditions are not advised to take this medicine. In the presence of heart problems along with erectile dysfunction, the doctor will explore alternative treatments for the patient’s safety.
  • Intagra 100 may induce dizziness; therefore, avoid tasks requiring concentration, such as driving or operating machinery, while under the influence of the medication.
