Papaverine hydrochloride 61-25-6

Papaverine hydrochloride (CAS No. 61-25-6) is an alkaloid derived from opium poppy plants. It is a smooth muscle relaxant that works by inhibiting the enzyme phosphodiesterase, leading to increased levels of cyclic adenosine monophosphate (cAMP) within cells. This results in relaxation of the smooth muscle in various organs, including blood vessels.

Papaverine hydrochloride is used in medicine to treat conditions involving spasm or constriction of smooth muscles, such as vasospasm (spasm of blood vessels) or conditions affecting the gastrointestinal tract, genitourinary system, and cardiovascular system. It is also sometimes used during certain surgical procedures to relax smooth muscle and improve blood flow.

As with any medication, papaverine hydrochloride should be used as prescribed by a healthcare provider to ensure safe and effective treatment. It may have side effects and interactions with other medications, so it is important to follow the guidance of a medical professional when using this medication.
