Valdecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, is classified as a nonsteroidal anti-inflammatory drug (NSAID). Valdecoxib was manufactured and marketed under the brand name Bextra. Bextra was indicated for relief of the signs and symptoms of osteoarthritis and adult rheumatoid arthritis. For the treatment of primary dysmenorrhea. But in 2005 FDA requested that Pfizer withdraw Bextra from the American market, because the Agency had concluded that the overall risk versus benefit profile of Bextra was unfavorable. That conclusion was based on the potential increased risk for serious cardiovascular (CV) adverse events, an increased risk of serious skin reactions (e.g., toxic epidermal necrolysis, Stevens-Johnson syndrome, erythema multiforme) compared to other NSAIDs, and the fact that Bextra had not been shown to offer any unique advantages over the other available NSAIDs.

Subitramine is a potent inhibitor of monoamines (serotonin, dopamine, noradrenaline) reuptake that was approved by FDA for the treatmen of obesity. Sibutramine is metabolized to metabolites M1 and M2 which are more active toward the monoamine transporters.The drug was withdrawn from the market because of clinical trial data indicating an increased risk of heart attack and stroke. It was sold under a variety of brand names including Reductil, Meridia and Sibutrex.

Halofantrine is a blood schizonticidal antimalarial agent with no apparent action on the sporozoite, gametocyte or hepatic stages of the infection. It is used only to treat but not to prevent malaria. Has been marketed by GlaxoSmithKline as HALFAN (halofantrine hydrochloride) in 250 mg tablets indicated for the treatment of adults who can tolerate oral medication and who have mild to moderate malaria (equal to or less than 100,000 parasites/mm3) caused by Plasmodium falciparum or Plasmodium vivax. Among side effects is cardiac arrhythmia. It belongs to the phenanthrene class of compounds that includes quinine and lumefantrine. It was reported that halofantrine binds to hematin in vitro (crystal structure of the complex) and to to plasmpesin, a haemoglobin degrading enzyme unique to the malarial parasites.
