The FDA has approved Exforge (Novartis) and Azor (Daiichi Sankyo), the first combinations of a calcium channel blocker (CCB) with an angiotensin receptor blocker (ARB) for treatment of hypertension. Amlodipine is the CCB in both products. The ARBs are valsartan in Exforge and olmesartan in Azor. All 3 of these drugs are available in fixed-dose combinations with other antihypertensive drugs.

The FDA has approved Furoscix (scPharmaceuticals), a subcutaneous formulation of the loop diuretic furosemide administered via a single-use, on-body infusor, for treatment of congestion due to fluid overload in adults with New York Heart Association (NYHA) Class II-III chronic heart failure (HF). Furosemide (Lasix, and generics) has been available for years in oral and IV formulations.

Some commonly used systemic drugs that may cause pulmonary toxicity are listed in the table below. These adverse effects may sometimes be difficult to distinguish from the underlying disease (JAD Cooper, Jr et al, Am Rev Respir Dis, 133:321, 488, 1986). Pulmonary effects that are part of a generalized reaction or are indirect effects of drugs - on respiratory muscles, for example, or on the immune system - are not included here.

As the weather becomes warmer, physicians may see more photosensitivity reactions due to systemic or topical drugs, perfumes, cosmetics or sunscreens. Even brief exposure to sunlight in warm or cold weather can cause intense cutaneous reactions in patients with drug-induced photosensitivity, and some patients may continue to be sensitive to sunlight long after stopping use of the offending agent.

Irbesartan (Avapro - Sanofi/Bristol-Myers Squibb) is the third angiotensin II receptor antagonist to become available in the USA for oral treatment of hypertension. Losartan (Cozaar) and valsartan (Diovan) were marketed earlier. Eprosartan (Teveten - SmithKline Beecham) has been approved by the FDA but not marketed.

Reports of increased mortality associated with calcium-channel blockers have caused concerns among patients taking these drugs and their physicians.

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.

Mibefradil dihydrochloride (Posicor - Roche), a chemically distinct nondihydropyridine calcium-channel blocker, has been approved by the US Food and Drug Administration (FDA) and is being heavily promoted as the first T-type calcium-channel blocker for treatment of hypertension and chronic stable angina.

The FDA has approved the use of aliskiren (Tekturna), a direct renin inhibitor, with valsartan (Diovan), an angiotensin-receptor blocker (ARB), in a fixed-dose combination as Valturna (Novartis) for treatment of hypertension in patients already taking both drugs or not adequately controlled on monotherapy, and as initial therapy in those likely to need multiple drugs to control their blood pressure.

In 2013 the FDA approved one new drug and a new combination of 2 old drugs as adjuncts to lifestyle changes for chronic weight management. Lorcaserin (lor-ca-SER-in; Belviq – Arena/Esai) is a selective serotonin 2C receptor agonist. Qsymia (Vivus) is a fixed-dose combination of the weight-loss drug phentermine and an extended-release (ER) formulation of topiramate. The new products are approved for use in obese patients (body mass index [BMI] of ≥30 kg/m2) and for patients who are overweight (BMI ≥27 kg/m2) and have one weight-related risk factor such as hypertension, dyslipidemia or...
