What is Flomax

TamsulosinThe Generic name of this drug

Treatment SummaryTamsulosin is a drug used to treat an enlarged prostate. It works by blocking certain receptors in the prostate and bladder, causing the muscles in these areas to relax. This relaxation allows for better urinary flow. It was approved by the FDA in 1997 and is more selective than other similar drugs, meaning it is less likely to cause a drop in blood pressure.

Effectiveness

How Flomax Affects PatientsTamsulosin is a drug that blocks the actions of certain alpha-1A and alpha-1D hormones, which are commonly found in the prostate and submaxillary tissue. This drug binds to these hormones more strongly than it does to alpha-1B hormones, found in the aorta and spleen. This makes it effective in improving urinary flow while having less adverse side effects like low blood pressure.

How Flomax works in the bodyTamsulosin is a medication that helps reduce symptoms of an enlarged prostate. It does this by blocking certain receptors in the prostate, specifically alpha-1A and alpha-1D. Blocking these receptors causes the smooth muscle in the prostate to relax, improving urinary flow. It also relaxes the muscles in the bladder, reducing the storage symptoms of an enlarged prostate. Tamsulosin is designed to be specific to the target area to minimize effects elsewhere in the body.

Flomax for Enlarged Prostate with Urination Problems

This treatment works great for me. If I miss even one or two doses, it's really difficult for me to urinate. I'm hopeful that there will be a long-term solution found eventually, but until then, this is a great stopgap measure.
