Naftopidil CAS No.57149-07-2 Pharmaceutical Intermediates
Introduction
Naftopidil is a selective alpha-1 adrenergic receptor antagonist widely used in the pharmaceutical industry to treat benign prostatic hyperplasia (BPH). BPH is a common condition in older men that causes urinary problems including frequent urination, urgency, and a weak urine stream. Naftopidil works by relaxing the smooth muscles of the prostate and bladder neck, thereby improving urine flow and relieving symptoms.
As a manufacturer and trader, we pride ourselves on producing high-quality Naftopidil to meet the specific needs of our customers in the pharmaceutical industry.
