Erectile Dysfunction (ED), also known as impotence, is a condition characterized by the inability to maintain an erection firm enough for sexual activity. It is one of the common sexual dysfunctions in men of all age groups; under the age 40 experiencing it more.  As per the World Health Organization, over approximately 15% of men, each year are affected by ED.


The causes for ED include:

  • Insufficient blood flow in the penis.
  • Damaged nerves in the penis.
  • Stress or emotional disturbances
  • Smoking
  • Excessive alcohol consumption
  • Lacking physical activity
  • Chronic health conditions such as atherosclerosis, high blood pressure, diabetes and heart disease.

Sometimes, drugs used to treat other health conditions can have a negative impact on erection.

ED is a major sign of cardiovascular disease. Men with ED are at high risk of heart stroke, heart attack and other circulatory problems. ED also causes depression and distress for the man and his partner.


  • Questionnaires – related to ED symptoms, personal life (reasons for stress, habits), and previous health history
  • Physical examination
  • Lab tests (blood test and urine test)
  • Other tests to check hormone levels


Fortunately, a range of treatments is available to treat ED. Chemotherapy, hormone therapy, penile injections, intraurethral medication, vacuum erection devices, penile implants, and surgery.

Chemotherapy is the first line of therapy for ED.

About Vigora

Vigora, manufactured by Zydus Cadila, is used for the treatment of ED or impotence. Vigora is a phosphodiesterase type 5 (PDE5) inhibitor drug used for the treatment of ED or impotence. Sildenafil citrate is the active ingredient in this drug. Sildenafil citrate relaxes the smooth muscles present in the wall of blood vessels, increases the flow of blood to the penis, and enhances the erection enough for the sexual activity. Vigora is as effective and safe as the original drug as the formula is the same as the original. However, it is cheaper than the original drug.

Vigora works effectively if the underlying cause of ED is physical, psychological, or both. Again, in psychological cases, the effectiveness of the drug depends on the severity of the condition. In both cases, it is important to undergo psychological counselling to achieve the best results (along with the standard treatment – Vigora Tablet).

The Vigora tablet could be used for the treatment of pulmonary arterial hypertension. It is generally not recommended for use in women and children. But for conditions like pulmonary arterial hypertension in women and in children aged more than 1 year, the treatment with Sildenafil could be considered.


The Vigora is available in the form of red tablets in the doses of 25, 50 0r 100 mg. It is taken orally with water. The maximum recommended daily dose of Vigora is 100 mg. If the patient is taking the tablet for the first time, usually the dosage should be limited to 50mg. The dosage can be adjusted based on the response to the dose.

The tablet is taken at least 30-60 minutes before sexual activity. The effect is observed within 30 minutes of administration of the dose and lasts up to 4 to 6 hours.

Mechanism of Action

During sexual activity, nitric oxide that enables the production of cGMP is released into the penis. cGMP is mainly responsible for the blood flow into the penis and for the firm erection of the penis. In men with ED, an enzyme phosphodiesterase type 5 (PDE5) destroys cGMP. Sildenafil citrate that belongs to the class of PDE5 inhibitors, stops the activity of PDE5. This causes the erection to last longer. In other words, the longer cGMP enzyme sustains during the sexual activity, the longer will be an erect penis. Vigora 100 mg tablet relaxes the smooth muscles present in the wall of blood vessels and increases the flow of blood to the penis for a longer time.

Side effects

The side effects include headache, lightheadedness, dizziness, nausea, muscle pain, nasal congestion, severe indigestion, blurred vision, hearing loss, prolonged and painful erection that lasts for more than 4 hours, sensitivity to light, and painful urination.
