| diltiazem | <chemical> A benzothiazepine derivative with vasodilating action due to its antagonism of the actions of the calcium ion in membrane functions. It is also teratogenic. Pharmacological action: antihypertensive agents, calcium channel blockers, cardiovascular agents, teratogens, vasodilator agents. Direct, potent negative chronotrope with only mild negative inotropic effect; slows conduction in AV node; coronary vasodilation with less systemic vasodilation than verpamil. Chemical name: 1,5-Benzothiazepin-4(5H)-one, 3-(acetyloxy)-5-(2-(dimethylamino)ethyl)-2,3-dihydro-2-(4-methoxyphenyl)-, (2S-cis)- Uses: Control ventricular response with atrial fibrillation Dose: 0.25 mg/kg IV over 2 minutes May repeat at 0.35 mg/kg after 15 minutes. Maintenance infusion at 5 - 15 mg/hr. Potential complications: Less hypotension than with verapamil since less vasodilation and myocardial depression; bradycardia; may exacerbate AV block; synergistic interaction with beta blockers; relatively contraindicated with congestive heart failure. Note: Diltiazem can accelerate heart rate and decrease blood pressure, especially in patients with Wolff-Parkinson-White or wide-complex tachycardia. (15 Mar 2000) |

| dilutional hyponatraemia | <biochemistry> Syndrome of inappropriate ADH (SIADH) secretion is a disorder of fluid and electrolyte balance which results from the excessive release of antidiuretic hormone (ADH). This results in the inability to excrete dilute urine. SIADH is seen in association with certain cancers (for example oat cell lung cancer, pancreatic, prostate, Hodgkin's disease), central nervous system disorders, head injury, myxoedema, psychosis and certain drugs. Symptoms include weight gain, nausea, vomiting, muscle cramps, confusion and convulsions. Incidence: approximately 7 out of 100,000 people. (27 Sep 1997) |
