Max Flow-D Cap 0.5mg/0.4mg combines the benefits of dutasteride and tamsulosin HCl to address the symptoms of benign prostatic hyperplasia. Dutasteride, one of the key ingredients works by blocking the conversion of testosterone into dihydrotestosterone (DHT). It helps to reduce the size of an enlarged prostate, relieving symptoms such as difficulty urinating and frequent urination. While tamsulosin HCl, acts as an alpha-blocker. It works by relaxing the muscles in the prostate and bladder neck, promoting easier urine flow and relieving the symptoms associated with BPH. By reducing the pressure on the urethra, tamsulosin HCl provides relief from urinary hesitancy, weak stream, and incomplete emptying of the bladder.
