Pharmacology: drug names, classification, and actions
| Question | Answer |
|---|---|
| nesiritide (Natrecor) | Vasodilator;Increases cyclic guanosine monophosphate (cGMP) level, relaxes smooth muscle, and dilates veins and arteries; To treat acute heat failure by increasing sodium loss in patients with dyspnea at rest or with minimal activity |
| Phenergan | Antiemetic-Phenothiazine;Blocks H1 receptor sites; inhibits chemoreceptor trigger zone. Treats motion sickness, N/V, nighttime sedation, adjunct to analgesics for routine preoperative or postoperative sedation, rhinitis (allergy symptoms) |
| digoxin (Lanoxin) | Cardiac glycoside; Inhibits sodium-potassium-activated adenosine triphosphatase, promoting increased force of cardiac contraction, and tissue perfusion; decreases ventricular rate; Heart failure, atrial tachycardia, flutter, or fibrillation |
| Quinidine | Antiarrhythmic;Decreases automaticity, conduction velocity, and membrane responsiveness; prolongs effective refractory period and reduces vagal tone;Atrial, ventricular, supraventricular dysrhythmias |
| diphenhydramine (Benadryl) | Antihistamine;Blocks histamine1 thereby decreasing allergic response; affects respiratory system, blood vessels, and GI system; Allergic rhinitis and itching; to prevent motion sickness; sleep aid; antitussive |
| azithromycin (Zithromax) | Antibiotic;Inhibition of the steps of protein synthesis;Gram-positive and some gram-negative organisms; for clients who are allergic to penicillin; to treat respiratory infections, gonorrhea, and skin infections. |
| Isoproterenol (Isuprel) | Bronchodilator; Relaxes bronchial smooth muscle by stimulating beta2 receptors. As a cardiac stimulant, acts on beta1 receptors in the heart;Bronchospasm during anesthesia, heart block, ventricular arrhythmias, shock |
| Anorexiants | CNS stimulant; Act on the brain to suppress appetite. They have a stimulant effect on the hypothalamic and limbic regions, which control satiety; Obesity |
| captopril (Capoten) | Antihypertensive; Inhibits ACE;Less angiotensin II decreases peripheral arterial resistance, decreasing aldosterone secretion;Hypertension, heart failure, diabetic nephropathy, left ventricular dysfunction, Raynaud phenomenon |
| Atropine sulfate (atropine) | Antiarrhythmic; Inhibition of acetylcholine by occupying the receptors; increase heart rate by blocking vagus stimulation; promote dilation of the pupils;Preoperative medication to reduce salivation, increase heart rate, dilate pupils |
| Barbiturates | Sedative-hypnotic; Barbiturates decrease presynaptic and postsynaptic membrane excitability;depress respiration and GI motility.It sedates, acts as a preanesthetic, for short term treatment of insomnia, for seizure disorders. |
| Pyridostigmine bromide (Mestinon) | Muscle stimulant;Transmission of neuromuscular impulses by preventing destruction of acetylcholine;To control and treat myasthenia gravis |
| Cimetidine | Antiulcer;Competitively inhibits action of histamine on the H2 receptor sites of parietal cells, decreasing gastric acid secretions;Treats duodenal ulcer, active benign gastric ulceration,Zollinger-Ellison syndrome,mastocytosis,adenomas, GERD, heartburn |
