Alpha blockers

Alpha blockers are pharmaceutical compounds that work by inhibiting the activity of alpha-adrenergic receptors, which are responsible for the contraction of smooth muscles. These medications are commonly used to treat conditions such as high blood pressure and benign prostatic hyperplasia by causing blood vessels to relax and widen. At CymitQuimica, we provide a range of alpha blockers suitable for research in pharmacology and cardiovascular health.
