Drug Categories
| Question | Answer |
|---|---|
| ALPHA-ADRENERGIC BLOCKERS | dilate peripheral blood vessels, lowering of peripheral resistance and the lowering of blood pressure. |
| ANTACIDS | neutralize gastric acidity. |
| ANTIANGINALS | nitrates,calcium channel blockers, and b-adrenergic blockers. |
| Nitrates | dilate coronary arteries, decrease preload and afterload. |
| Calcium channel blockers | also dilate coronary arteries, but they also decrease SA/AV node conduction |
| β -Adrenergic blockers | slow the heart rate, thus decreasing O2 use. |
| ANTICHOLINERGICS | Inhibit acetylcholine (autonomic nervous system) |
| ANTICOAGULANTS | Prevent clot formation |
| ANTICONVULSANTS | barbiturates,hydantoins,succinimides,benzodiazepines and others |
| ANTICONVULSANTS | Act to prevent seizures |
| ANTIDEPRESSANTS | MAOIs,tricyclics, and others |
| MAOIs | inhibit MAO and thus they increase epinephrine, norepinephrine, serotonin, and dopamine |
| Tricyclics | block the reuptake of serotonin and norepinephrine in the nerve endings, thus increasing the actions of both in the nerve cells |
| ANTIDIABETIC MEDICATIONS | insulins of varying kinds, and oral hypoglycemic agents |
| Insulin | lowers blood sugar, potassium and phosphate |
| Oral hypoglycemic agents | stimulate the β -cells of the pancreas to release insulin |
| ANTIDIARRHEALS | some decrease water content of stool, some slow down GI peristalsis |
| ANITDYSRHYTHMICS | • Class I • Class II • Class III • Class IV • Others |
| Class I | decreases any disparity in the refractory period, increases the duration of action potential and effective refractory period |
| Class II | slows down the rate of SA node discharge and conduction through the AV node. Increases recovery time and decreases the heart rate |
| Class III | increases effective refractory period as well as the duration of action potential |
| Class IV | decreases SA node discharge and slows the conduction velocity through the AV node; they also inhibit calcium movement across the cell. |
| Others | slows conduction through the AV node (adenosine) and increases the refractory period in the AV node and decreases conduction velocity (digoxin) |
| ANTIFUNGALS | decreases sodium, potassium and nutrients in the cell and increases cell permeability |
| ANTIHISTAMINES | antagonists of histamine |
| ANTIHYPERTENSIVES | • angioten sin-converting enzyme (ACE) inhibitors • b-adrenergic blockers • calcium channel blockers • centrally acting adrenergics • diuretics • peripherally acting antiadrenergics, and • vasodilators |
| Angiotensin | dilatation of the arterial and venous systems occur through the suppression of renin-angiotensin I to angiotensin II conversion |
| Centrally acting adrenergics | inhibit impulses in the CNS and the sympathetic nervous system, decreases cardiac output, blood pressure and pulse rate |
