How calcium channel blocker helps in reducing hypertension?
-
Hello, my wife is 45 years old. She is hypertensive also. She used to have headaches, shortness of breath and nosebleeds. Doctor has prescribed her calcium channel blocker to bring down blood pressure to normal along with life style changes. She is taking it regularly. I am trying to look for the mechanism of action of calcium channel blocker with its any specified adverse effect. Please let me know.

@gagan Calcium channel blockers (CCBs) reduce blood pressure by limiting the amount of calcium or the rate at which calcium flows into the heart muscle and arterial cell walls. Calcium stimulates the heart to contract more forcefully. When calcium flow is limited, heart’s contractions aren’t as strong with each beat, and blood vessels are able to relax. This leads to lower blood pressure. CCBs are available in a number of oral formats, ranging from short-acting dissolving tablets to extended-release capsules. The dosage will depend on overall health and medical history. Doctor will also take age of the patient into consideration before prescribing a blood pressure-lowering medication. CCBs are often less likely to cause side effects in people over the age of 65.
