About brand name of the drug

Modula 5 mg is a brand manufactured by one of the topmost Indian based company Sun Pharma Laboratories which is a generic form of Tadalafil which is available in the form of tablets. This low-medium potency medication is recommended for the therapy of erectile dysfunction, pulmonary arterial hypertension and benign prostate hyperplasia in males. It is one of the best ways to treat erectile dysfunction in males along with minimum side effects.

About the drug 

Modula 5 mg contains Tadalafil as the active constituent. The tablets contain 5 mg of the active drug which is equivalent to Tadalafil. Modula 5 mg contains a low amount of drug which is sufficient enough to sustain the erections for an extended period of time without penile failure at the peak time. 

About salt of the drug

Modula 5 mg belongs to the class of PDE5 inhibitors. This drug results in relaxation of the walls of the smooth vessels in the penile region. As a result, blood vessels are dilated and there is an easy passage for an increased volume of blood. This increased blood flow for an extended period of time provides sustained erections which allow the males to have a pleasant sexual experience.

Medical Uses of the drug

  • Erectile dysfunction – Condition in which there is difficulty to sustain a penile erection during the sexual activity
  • Benign prostate hyperplasia – Condition where there is enlargement of the prostate gland which results in difficulty in urination
  • Pulmonary arterial hypertension (PAH) – Increase in blood pressure of the vessels of the lungs due to obstruction in the arteries
  • Enhanced male libido – Increased sex drive or sexual desire
  • Magnified sexual performance – Powerful erections sustain for a long period of time thus, improving sexual performance

Working of a drug 

The active constituent of Modula 5 mg, Tadalafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5) which is responsible for the breakdown of cGMP. A higher amount of cGMP results in relaxation of smooth muscles in the walls of the blood vessels. This causes an increased blood flow into the penile region and a sustained erection is possible for an extended period of time for those who suffer from erectile dysfunction. It does not result in penile failure at peak time and helps patients attain their level of sexual pleasure. This drug is also used in treating the enlarged prostate gland which causes difficulty in the passage of urine.

Side effects

  • Headache
