Thanks for the query
Teenagers can prevent
hypertension ESP if they have a family history of it by not taking up
smoking, drinking and not become over weight. Do cardio exercises regularly
About how medications work it Is difficult to tell because there are many class of drugs and each act differently. For eg ace inhibitors acts by inhibiting
angiotensin converting enzyme. Like that there are calcium channel blockers, centrally acting ones etc
Have a healthy life
