Gallium nitrate (Ganite - Fujisawa, USA), originally an anticancer drug, was recently marketed for treatment of cancer-associated hypercalcemia that has not responded to hydration. Other drugs used for treatment of hypercalcemia include furosemide (Lasix, and others), the bisphosphonate etidronate (Didronel IV), calcitonin (Calcimar), and plicamycin (Mithracin, formerly mithramycin) (RAB Schaiff et al, Clin Pharm, 8:108, 1989). Newer bisphosphonates are available in Europe.

Podofilox 0.5% solution (Condylox - Oclassen) was recently approved by the US Food and Drug Administration for treatment of (condylomata acuminata). The drug requires a prescription, but is labeled for application by the patient. Similar topical solutions previously available for this indication are approved only for application by the physician.

Flosequinan (Manoplax - Boots), a fluoroquinolone derivative, is now available in the USA for treatment of congestive heart failure. Labeling approved by the US Food and Drug Administration recommends the drug only for patients who cannot tolerate or have not responded adequately to an angiotensin-converting enzyme (ACE) inhibitor.

Terazosin (Hytrin - Abbott), a postsynaptic alpha 1 -adrenoreceptor blocker previ-ously available for treatment of hypertension (Medical Letter, 29:113, 1987), has now been approved by the US Food and Drug Administration (FDA) for treatment of benign prostatic hyperplasia (BPH). Although not previously approved by the FDA, terazosin and other alpha-blockers such as prazosin (Minipress, and others) or doxazosin (Car-dura) have been used for this indication for many years.

Recombinant human deoxyribonuclease I (rhDNase; dornase alfa; Pulmozyme - Genentech), an enzyme that hydrolyzes extracellular DNA, is now available as a purified solution to decrease the viscosity of sputum in patients with cystic fibrosis. It requires a nebulizer to produce an aerosol mist for inhalation.

Aprotinin (Trasylol - Miles), an inhibitor of fibrinolysis first identified in 1930, was recently approved by the US Food and Drug Administration for intravenous use in high-risk coronary artery bypass graft (CABG) surgery to decrease bleeding and the need for transfusion. Inhibitors of fibrinolysis previously available in the USA include aminocaproic acid (Amicar, and others) and tranexamic acid (Cyklokapron - Medical Letter, 29:89, 1987).

Mycophenolate mofetil (CellCept - Roche) has been approved by the US Food and Drug Administration for oral use in preventing organ rejection in patients receiving allogeneic renal transplants.

Recent articles in the press have suggested that in early pregnancy, an intramuscular (IM) injection of methotrexate (Folex, and others), a folic acid antagonist, and oral or vaginal administration of misoprostol (Cytotec), a prostaglandin, offers a medical alternative to a surgically induced abortion. Methotrexate is approved by the US Food and Drug Administration for use in rheumatoid arthritis, psoriasis and various types of cancer, including choriocarcinoma, and has also been used to terminate ectopic pregnancies. Misoprostol is approved for prevention of gastric ulcers induced by...

Alteplase, a recombinant tissue plasminogen activator (TPA; Activase - Genentech), has been approved by the US Food and Drug Administration (FDA) for intravenous (IV) treatment of acute ischemic stroke. Several thrombolytic agents, including alteplase, were previously approved for use in acute myocardial infarction and acute massive pulmonary embolism (Medical Letter, 29:107, 1987; 32:15, 1990).
