The importance of adequate control of hypertension in preventing organ damage and death is well established, but the choice of drugs is still controversial. Three recent drug trials, one supporting initial therapy with a diuretic, the second favoring an angiotensin converting enzyme (ACE) inhibitor, and the third showing equivalence between a calcium-channel blocker and an angiotensin-receptor blocker (ARB) have intensified the debate.

American College of Cardiology/American Heart Association (ACC/AHA) guidelines for treatment of hypertension were last published in 2018. Treatment of hypertensive urgencies and emergencies is not discussed here.

Captopril and enalapril have also been approved by the FDA for treatment of congestive heart failure.

The FDA has approved ponesimod (Ponvory – Janssen), a sphingosine 1-phosphate (S1P) receptor modulator, for treatment of adults with relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome (initial neurological episode), relapsing-remitting disease, and active secondary progressive MS (SPMS). Ponesimod is the fourth oral S1P receptor modulator to be approved in the US for once-daily treatment of relapsing forms of MS; ozanimod (Zeposia) and siponimod (Mayzent) are also approved for use in adults, and fingolimod (Gilenya) is indicated for use in patients...

Amlodipine (am loe' di peen) besylate (Norvasc - Pfizer), a dihydropyridine calcium-channel blocker, has been approved by the US Food and Drug Administration for once-daily oral treatment of hypertension, chronic stable angina, and vasospastic (Prinzmetal's) angina.

It is approved for patients already taking a combination of rosiglitazone and a sulfonylurea or those not adequately controlled on rosiglitazone or sulfonylurea monotherapy. Rosiglitazone is also available in a fixed-dose combination with metformin (Avandamet). Most patients with type 2 diabetes eventually require 2 drugs with different mechanisms to control...
