<unk>  is a vasopressor/antihypotensive agent (it raises the blood pressure).<unk>  was approved in the United States by the Food and Drug Administration (FDA) in 1996 for the treatment of dysautonomia and orthostatic hypotension. In August 2010, the FDA proposed withdrawing this approval because the manufacturer, Shire plc, failed to complete required studies after the medicine reached the market. In September 2010, the FDA reversed its decision to remove<unk>  from the market and allowed it to remain available to patients while Shire plc collected further data regarding the efficacy and safety of the drug. Shire announced on September 22, 2011 that it was withdrawing completely from supplying<unk>  and leaving it to several generics to supply the drug.
