| beta-adrenergic blocking agent | A class of drugs that compete with beta-adrenergic agonists for available receptor sites; some compete for both b1 and b2 receptors (e.g., propranolol) while others are primarily either b1 (e.g., metoprolol) or b2 blockers; used in the treatment of a variety of cardiovascular diseases where beta-adrenergic blockade is desirable. Synonym: beta-adrenergic receptor blocking agent, beta-adrenoreceptor antagonist, beta-blocker. (05 Mar 2000) |

| bronchoconstrictor agent | Agents causing the narrowing of the lumen of a bronchus or bronchiole. (12 Dec 1998) |
| cardiotonic agent | Agents that have a tonic effect on the heart or increase cardiac output. They may be glycosidic steroids related to digitalis products, sympathomimetic, or other drugs and are used after myocardial infarcts, cardiac surgery, in shock, or in congestive heart failure.

| ganglionic blocking agent | An agent that impairs the passage of impulses in autonomic ganglia. (05 Mar 2000) |
| reducing agent | A molecule that donates an electron in an oxidation-reduction reaction. (09 Oct 1997) |
| reovirus-like agent | <virology> Genus of the Reoviridae having a double layered capsid and 11 double stranded RNA molecules in the genome. They have a wheel like appearance in the electron microscope and cause acute diarrhoeal disease in their mammalian and avian hosts. Probably the most important cause of severe dehydrating diarrhoea in children under three years of age worldwide. Symptoms include nausea, vomiting, low-grade fever and diarrhoea. Aggressive fluid replacement is generally required. (27 Sep 1997) |
| chemotherapeutic agent | Chemotherapeutic agents are those medications that are used to treat various forms of cancer. These medications are given in a particular regimen over a period of weeks. most chemotherapeutic medications have the ability to directly kill cancer cells. For this same reason, these medications can suppress the bone marrow to some degree, lowering white blood cell counts. This results in a condition known as immunosuppression and can place the patient at an increased risk of infection. Examples include busulphan, cisplatin, cyclophosphamide, methotrexate, daunorubicin, doxorubicin, melphalan, vincristine, vinblastine and chlorambucil. See: immunosuppressive agents. (27 Sep 1997) |
