1.What is Hydralazine HCL?aasraw

 

Hydralazine is used to treat high blood pressure(hypertension). It is also used to control high blood pressure in a mother during pregnancy (pre-eclampsia or eclampsia) or in emergency situations when blood pressure is extremely high (hypertensive crisis).

Hydralazine Hydrochloride(Hydralazine HCL) is the hydrochloride salt of hydralazine, a phthalazine derivative with antihypertensive and potential antineoplastic activities. Hydralazine alters intracellular calcium release and interferes with smooth muscle cell calcium influx, resulting in arterial vasodilatation. This agent also inhibits the phosphorylation of myosin protein and chelation of trace metals required for smooth muscle contraction, resulting in an increase in heart rate, stroke volume and cardiac output. In addition to its cardiovascular effects, hydralazine inhibits DNA methyltransferase, which may result in inhibition of DNA methylation in tumor cells.

2.How Hydralazine HCL works?aasraw

 

High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure can decrease the risk of heart attacks and strokes.

Hydralazine works by relaxing the blood vessels and increasing the supply of blood and oxygen to the heart while reducing its workload. It isn’t fully understood how hydralazine works. It’s thought that the drug acts on the blood vessels directly and relaxes them. This results in lower blood pressure levels.

Hydralazine belongs to a class of drugs called peripheral vasodilators. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.

Hydralazine is a vasodilator that works by relaxing the muscles in your blood vessels to help them dilate (widen). This lowers blood pressure and allows blood to flow more easily through your veins and arteries.
