Vanishing twin. A vanishing twin, also known as fetal resorption, is a fetus in a multi-gestation pregnancy which dies in utero and is then partially or completely reabsorbed by the twin.
GENERIC NAME: oxycodone. BRAND NAMES: OxyContin, Roxicodone, Oxecta. Oxycodone is prescribed for the management of pain severe enough to require daily, around-the-clock, long-term treatment with a narcotic, and for which alternative treatment options are inadequate for the relief of moderate to severe pain.
OxyContin contains between 10 and 80 milligrams of oxycodone in a timed-release formula that allows up to 12 hours of relief from chronic pain. What distinguished OxyContin from other analgesics was its long-acting formula, a blessing for patients who typically need round-the-clock relief.
