This medicine combines two drugs to treat enlarged prostate in men. It helps improve urine flow and reduce symptoms.
Nifedipine is a calcium channel blocker. It helps to relax blood vessels, which can lower blood pressure and reduce chest pain.
This medicine treats benign prostatic hyperplasia (BPH), also known as enlarged prostate, in men. It helps to relieve symptoms like frequent urination, difficulty starting urination, and weak urine stream. This medicine is not approved to prevent prostate cancer.
This medicine treats chest pain (angina) caused by tight blood vessels. It also treats high blood pressure. Lowering blood pressure reduces the risk of strokes and heart attacks.
This medicine contains two drugs that work in different ways. Dutasteride lowers a hormone called DHT that causes the prostate to grow. Tamsulosin relaxes the muscles in the prostate and bladder, making it easier to urinate.
Nifedipine blocks calcium from entering heart and blood vessel cells. This relaxes and widens blood vessels. As a result, the heart doesn't have to work as hard, and blood pressure goes down.

How to Read This dutasteride/tamsulosin vs nifedipine Comparison
dutasteride/tamsulosin is classified in the 5-ARI / Alpha-Blocker Combination drug class, while nifedipine sits within the Calcium Channel Blocker class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, dutasteride/tamsulosin has 5,191 submissions while nifedipine has 11,214. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to these two drugs do not interfere with each other, so the amount of medicine in your body stays the same.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for dutasteride/tamsulosin or nifedipine.
