Adafil 20 mg is an oral medication containing tadalafil, a selective phosphodiesterase type 5 (PDE5) inhibitor. It is primarily used for the management of erectile dysfunction (ED) and benign prostatic hyperplasia (BPH), as well as in patients experiencing both conditions simultaneously. By improving blood flow and relaxing smooth muscle tissues, Adafil 20 mg helps restore sexual function and relieve urinary symptoms associated with prostate enlargement.

Therapeutic Class

Drugs for Erectile Dysfunction

Indications

Adafil 20 mg is indicated for:

• Erectile Dysfunction (ED)

• Benign Prostatic Hyperplasia (BPH)

• Treatment of patients with both Erectile Dysfunction and signs and symptoms of Benign Prostatic Hyperplasia

Pharmacology and Mode of Action

Adafil 20 mg acts as a selective phosphodiesterase type 5 (PDE5) inhibitor. PDE5 is responsible for the degradation of cyclic guanosine monophosphate (cGMP). By inhibiting this enzyme, tadalafil increases cGMP levels within smooth muscle cells. Elevated cGMP leads to smooth muscle relaxation and enhanced blood flow to the corpus cavernosum, resulting in a natural erectile response during sexual stimulation.

PDE5 is also found in the smooth muscles of the prostate and bladder wall. Inhibition of PDE5 in these tissues leads to relaxation of smooth muscle, improved blood flow in the lower urinary tract, and widening of the bladder neck. These effects help reduce urinary symptoms such as difficulty in urination, weak stream, and incomplete bladder emptying associated with BPH.

A distinguishing feature of Adafil 20 mg is its long duration of action, remaining effective for up to 36 hours, allowing greater flexibility in sexual activity.

Dosage and Administration

• Erectile Dysfunction:
  The recommended starting dose is 10 mg taken prior to anticipated sexual activity. Based on individual response and tolerability, the dose may be increased to 20 mg or decreased to 5 mg. The maximum recommended dosing frequency is once daily.

• Benign Prostatic Hyperplasia:
  The recommended dose is 5 mg taken once daily at the same time each day.

• Combined ED and BPH:
  A dose of 5 mg once daily at the same time each day is recommended.

Adafil 20 mg may be taken with or without food.

Adafil 20 mg may interact with nitrates such as nitroglycerin and isosorbide, alpha-adrenergic blockers, antihypertensive drugs, alcohol, antacids containing magnesium or aluminum hydroxide, and strong CYP3A4 inhibitors including ketoconazole, itraconazole, ritonavir, and erythromycin. Interactions may also occur with grapefruit juice, HIV protease inhibitors, rifampin, carbamazepine, phenytoin, and phenobarbital.

Contraindications

• Concomitant use of nitrates due to the risk of severe hypotension

• Known hypersensitivity to tadalafil or any component of the formulation

Side Effects

Common side effects include headache, dyspepsia, back pain, myalgia, nasal congestion, and nasopharyngitis. Rare but serious adverse events may include visual disturbances, sudden vision or hearing loss, severe skin reactions, angina, myocardial infarction, stroke, severe hypotension, and tachycardia.
