THIOTEPA Wyeth-Ayerst Cytotoxic Agent Action and Clinical Uses: Thiotepa is a cytotoxic agent of the polyfunctional alkylating type (more than one reactive ethylenimine group) related chemically and pharmacologically to nitrogen mustard. Its radiomimetic action is believed to occur through the release of ethylenimine radicals which, like irradiation, disrupt the bonds of DNA. One of the principal bond disruptions is initiated by alkylation of guanine at the N-7 position, which severs…

THROMBATE III® Bayer Antithrombin III (Human) Anticoagulant Action and Clinical Uses: Antithrombin III (AT-III), an alpha 2-glycoprotein of molecular weight 58 000, is normally present in human plasma at a concentration of approximately 12.5 mg/dL and is the major plasma inhibitor of thrombin. Inactivation of thrombin by AT-III occurs by formation of a covalent bond resulting in an inactive 1:1 stoichiometric complex between the two, involving an interaction of the active serine…

THEOCHRON® SR Riva Theophylline Bronchodilator Action and Clinical Theophylline is a bronchodilator which directly relaxes the smooth muscle of the bronchial airways and pulmonary and coronary blood vessels. These actions may be mediated through inhibition of phosphodiesterase and a resultant increase in intracellular cyclic AMP. Theophylline sustained release tablets produce peak blood levels of theophylline between 5 and 8 hours following dosing in adults. Once a steady state level has…
