Nearly 8% of all patients newly prescribed a hypertension drug in this major study, and 17% in one subset, actually experienced a blood pressure increase, depending on type of drug(s) prescribed.
Commonly prescribed drugs used to lower blood pressure can actually have the opposite effect - raising blood pressure in a statistically significant percentage of patients.
A new study suggests that doctors could avoid this problem - and select drugs most suitable for their patients - by measuring blood levels of the enzyme renin through a blood test that is becoming more widely available. (Renin is an enzyme the kidneys produce that sets off a series of chemical changes resulting in increased blood pressure.)
