In 1989, Photoplex (Allergan Herbert), a combination of the dibenzoyl methane avobenzone (Parsol 1789) and the aminobenzoic acid (PABA) ester padimate O, was the first 'broad spectrum' sunscreen to become available in the USA (Medical Letter, 31:59, 1989). Now, Shade UVAGuard (Schering-Plough), a similar product, has been approved by the US Food and Drug Administration; it also contains avobenzone, plus the benzophenone oxybenzone and octyl methoxycinnamate.

Glatiramer acetate (Copaxone - Teva Marion Partners), formerly known as copolymer-l, has been approved by the US Food and Drug Administration (FDA) for treatment of relapsing-remitting multiple sclerosis (MS).

Once-a-week formulations of alendronate (Fosamax) in 35- and 70-mg tablets have now been approved by the FDA and are being heavily promoted for prevention and treatment of postmenopausal osteoporosis.

A new once-daily formulation of gabapentin (Gralise – Depomed) has been approved by the FDA for treatment of postherpetic neuralgia (PHN).

Extended-release gabapentin enacarbil (Horizant) was recently approved by the FDA for treatment of restless legs syndrome.

The results of the Age-Related Eye Disease Study 2 (AREDS2) have now been published. The primary purpose of the study was to evaluate the efficacy and safety of the carotenoids lutein and zeaxanthin and the omega-3 polyunsaturated fatty acids (PUFAs) docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) in reducing the risk of developing advanced age-related macular degeneration (AMD). A secondary goal was to test the effects of reducing the amount of zinc and eliminating beta carotene from the original AREDS formulation. Beta carotene has been shown to increase the risk of...

The FDA has approved Diclegis (Duchesnay), a fixed-dose, delayed-release combination of the H1-antihistamine doxylamine and the vitamin B6 analog pyridoxine, for treatment of nausea and vomiting of pregnancy in women who do not respond to conservative management.

Doxylamine and pyridoxine, both currently available over the counter, were previously available by prescription in a fixed-dose combination (Bendectin) for morning sickness. Bendectin was voluntarily withdrawn in the US in 1983 because of claims of teratogenicity that have since been...

Belotero Balance (Merz), an injectable hyaluronic acid dermal filler, has been approved by the FDA for temporary correction of moderate-to-severe facial wrinkles and folds.

They have supplanted bovine collagen products, which persist for a shorter time and cause more allergic reactions.

Pertuzumab in combination with trastuzumab and docetaxel was approved earlier for treatment of HER2-positive metastatic breast cancer. Pertuzumab is the first drug to be approved for neoadjuvant treatment of...
