Misoprostol (Cytotec - Searle), a synthetic methyl analog of prostaglandin E1, was recently approved by the US Food and Drug Administration for prevention of gastric ulcers in high-risk patients taking nonsteroidal anti-inflammatory drugs (NSAIDs). In other countries, the drug is also marketed for treatment of idiopathic peptic ulcers unrelated to NSAIDs.

The FDA has approved an extended-release oral formulation of the opioid agonist hydrocodone (Zohydro ER – Zogenix) for management of pain severe enough to require continuous, long-term therapy and for which alternative treatment options are inadequate. Zohydro ER is the first single-ingredient hydrocodone product to be marketed in the US. Hydrocodone has been available for years in combination with acetaminophen (Vicodin, and others) or ibuprofen (Vicoprofen, and others).

More antibiotics are prescribed for treatment of acute otitis media (AOM) than for any other infection in young children. Children with AOM typically present with otalgia, fever, and bulging and erythema of the tympanic membrane.

Nabumetone (Relafen - SmithKline Beecham), a new nonsteroidal anti-inflammatory drug (NSAID), has been approved by the US Food and Drug Administration for treatment of rheumatoid arthritis and osteoarthritis. The drug has been available in the United Kingdom since 1987. The manufacturer claims that nabumetone is as effective as other NSAIDs and causes a relatively low incidence of peptic ulcers.

Valdecoxib (Bextra - Pharmacia/Pfizer), a selective cyclooxygenase (COX-2) inhibitor similar to celecoxib (Celebrex) and rofecoxib (Vioxx), was recently approved by the FDA for treatment of osteoarthritis, rheumatoid arthritis and primary dysmenorrhea.

Rofecoxib (Vioxx - Merck) has been withdrawn from the market due to an increased risk of cardiovascular complications associated with its long-term use. The question remains whether all selective COX-2 inhibitors carry the same risk. Full-page advertisements in newspapers for celecoxib (Celebrex - Pfizer), the most widely used COX-2 inhibitor, assure the public that it does not.

When patents expire on brand-name drugs and generic formulations become available, patients and managed care organizations may express a preference for the lower-cost generics. Are they equivalent to the brand-name product?

Solar ultraviolet (UV) light capable of injuring the skin is classified by wavelength into UVA I (340-400 nm), UVA II (320-340 nm) and UVB (290-320 nm). UVB is responsible for most of the erythema of sunburn. UVA has been implicated in the development of phototoxicity and photoaging. The FDA permits sunscreen manufacturers to claim broad-spectrum protection if their products block at least part of UVA II in addition to UVB.

With the removal of Vioxx from the market and concerns about cardiovascular toxicity with other selective COX-2 inhibitors, patients are looking for safe alternatives, and manufacturers of other drugs are looking for additional market share. The COX-2 inhibitors first became popular because they have less upper GI toxicity than older less selective NSAIDs, at least in the short term, in patients not taking aspirin.
