📌 What is Tadalafil?

Tadalafil is a prescription oral medication that works by relaxing the smooth muscles of blood vessels, improving blood flow to certain parts of the body. Its primary use is in the treatment of erectile dysfunction, but it also plays a role in managing BPH and PAH.

🔬 How It Works

This medication works by inhibiting the enzyme PDE5, which regulates blood flow in the penis, lungs, and prostate. By blocking PDE5, This medication increases levels of cyclic guanosine monophosphate (cGMP), leading to relaxed blood vessels and improved blood circulation.

✅ Approved Uses

1. Erectile Dysfunction (ED)

Tadalafil enhances erectile response when a man is sexually aroused. Unlike other ED medications, it has a longer duration of action—up to 36 hours—earning it the nickname “the weekend pill.”

Dose:

• Typically 10 mg before anticipated sexual activity.
• Can be increased to 20 mg or decreased to 5 mg depending on effectiveness and tolerance.
• For daily use: 2.5 mg to 5 mg once daily.

2. Benign Prostatic Hyperplasia (BPH)

BPH is a condition in which the prostate gland enlarges, leading to urinary symptoms such as difficulty urinating or frequent urination. This medication improves urinary flow by relaxing muscles in the prostate and bladder.

Dose:

• 5 mg once daily, taken at the same time every day.

3. Pulmonary Arterial Hypertension (PAH)

This medication improves the ability to exercise in people with PAH by lowering blood pressure in the lungs, which reduces the workload on the heart.

Dose:

• 40 mg once daily (two 20 mg tablets).
