Description

Udenafil is a phosphodiesterase type 5 (PDE5) inhibitor medication used primarily for the treatment of erectile dysfunction (ED). It enhances erectile response by increasing blood flow to the penis during sexual stimulation, allowing for improved sexual performance.

Uses / Indications

  • Erectile dysfunction (ED)
  • Pulmonary arterial hypertension (in some cases)
  • Enhancement of sexual arousal and performance in men

Dosage and Administration

Adults:
The recommended starting dose is 100 mg taken approximately 30 minutes before sexual activity, with a maximum recommended dose of 200 mg within 24 hours.

Note: Dosage adjustments may be made based on efficacy and tolerability; consult a physician for personalized instructions.

How It Works (Mechanism of Action)

Udenafil works by selectively inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for the degradation of cGMP in penile tissue. Increased levels of cGMP lead to relaxation of smooth muscle and increased blood flow, facilitating an erection when combined with sexual stimulation.
