Dutasteride and tamsulosin hydrochloride capsules contain two medicines to treat enlarged prostate in men. They help improve symptoms like frequent urination.
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 with symptoms like needing to urinate often, especially at night. It is for men who have an enlarged prostate causing these problems. 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.
Dutasteride lowers a hormone called dihydrotestosterone (DHT) that causes the prostate to grow. Tamsulosin relaxes the muscles in the prostate and bladder. This combination helps urine flow more easily.
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 vs nifedipine Comparison
dutasteride is classified in the 5-Alpha Reductase Inhibitor 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 has 5,189 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 medications do not significantly change how the body processes or removes each other.. 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 or nifedipine.
