Tadafil
Form: Tablet
Strength: 5mg
Generic Name: Tadalafil
Company: Astra Biopharmaceuticals Ltd.
MRP:৳ 18.0 (Tablet)
Is Antibiotic: No
Indications
Tadafil is indicated for the treatment of Erectile Dysfunction (ED), Benign Prostatic Hyperplasia (BPH), or both ED and symptoms of BPH.
Pharmacology
Tadafil is a selective inhibitor of phosphodiesterase type 5 (PDE5). By inhibiting PDE5, Tadafil increases the levels of cGMP in smooth muscle cells. This helps relax the smooth muscles and increase blood flow to the penis, causing an erection. PDE5 is also found in the prostate and bladder wall, so inhibiting Tadafil improves blood flow and helps with urination by relaxing smooth muscles in those areas.
Dosage & Administration
Erectile Dysfunction: The recommended starting dose is 10 mg, which can be adjusted to 5 mg or 20 mg based on individual needs. The maximum dosing frequency is once a day. Tadafil is effective for up to 36 hours.
Benign Prostatic Hyperplasia: The recommended dose is 5 mg once daily, at the same time each day.
Combined Erectile Dysfunction and Benign Prostatic Hyperplasia: The recommended dose is 5 mg once daily, at the same time each day.

Tadafil may interact with nitrates (e.g., Isosorbide, Nitroglycerin), alpha blockers, antihypertensives, alcohol, antacids, certain antifungals (e.g., Ketoconazole, Itraconazole), HIV protease inhibitors (e.g., Ritonavir), Erythromycin, Grapefruit juice, and other medications like Rifampin, Carbamazepine, Phenytoin, and Phenobarbital.
Contraindications
Tadafil is contraindicated for use with nitrates (e.g., Nitroglycerine, Isosorbide) due to the risk of dangerously low blood pressure. Tadafil should also not be used in patients with hypersensitivity to Tadalafil.

Pregnancy & Lactation
Tadafil has been assigned pregnancy category B by the USFDA, meaning Tadafil is only recommended during pregnancy if the benefits outweigh the risks. There is no data on its excretion in human milk, so caution is advised when giving Tadafil to breastfeeding women.
