reversible airway obstruction, exercise induced asthma

bronchodilation through stimulation of beta 2 adrenergic receptors

bronchodilators

adrenergics

• instruct patient to avoid excessive use • can cause headache palpitations tachycardia, abdominal pain, paradoxical bronchospasm • beta blockers and decrease effectiveness • assess respiratory status • may increase glucose levels • always take bronchodialtor first

Rimactane

tuberculosis

inhibits RNA synthesis

Antitubercular

rifamycins

• can turn body fluids red • may cause diarrhea, nausea, vomiting, confusion • assess lung sounds and sputum characteristics • evaluate renal and liver function tests • instruct patient not to skip or double dose • must complete entire dose (6-12 month therapy)

Zantac

duodenal ulcers, GERD, heartburn, esophagitis, GI bleed

inhibits action of histamine in gastric parietal cells, decreases gastric acid secretion

antiulcer agents

histamine H2 antagonists

• may cause arrhythmias, agranulocytosis, aplastic anemia, confusion • assess abdominal pain • monitor for blood in stool • monitor CBC

Seroquel

schizophrenia, depressive disorder, mania

dopamine and serotonin antagonist

antipsychotic, mood stabilizers

none

• may cause neurolyptic malignant syndrome, seizures, dizziness, palpitations, weight gain, anorexia • QT interval prolongation • don't use with CNS depressants • assess weight frequently • monitor liver function test and CBC • may increase cholesterol

PTU

hyperthyroidism

inhibits thyroid hormones

Antithyroid Agent

none

• hepatotoxicity, nausea, vomiting, agranulocytosis • monitor symptoms of hyperthyroidism • monitor for hypothyroidism • monitor WBC and liver function tests • weight patient frequently • may cause leukopenia, thrombocytopenia, jaundice • take with meals

Inderal

hypertension, angina, arrhythmias, cardiomyopathy, alcohol withdrawal, anxiety

blocks Beta 1 and 2 adrenergic receptors

antianginal, antiarrhythimic (class II beta blockers), antihypertensive, headache suppressant

beta blocker

• contraindicated in CHF, pulmonary edema, cardiogenic shock, bradycardia, heart block • monitor hemodynamic parameters (HR, BP) • may cause bradycardia, CHF, pulmonary edema • masks symptoms of hypoglycemia associated with diabetes mellitus • advise to change positions slowly to prevent orthostatic hypotension • instruct patient on how to take blood pressure • stopping abruptly may result in life threatening arrhythmias • monitor daily intake and output • advise patient to notify physician for difficulty breathing

Diprivan

anesthesia, induction, sedation,

hypnotic, produces amnesia with no analgesic properties

general anesthetic

none

• use cautiously with CVD, lipid disorder, increased ICP • can cause apnea, bradycardia, hypotension • burning and pain at insertion site • can turn urine green • assess respiratory status and hemodynamics • maintain patent airway • assess level of sedation

Phenergan

allergic reactions, nausea and vomiting, sedation

Blocks the effects of histamine, histamine plays a role in the immune response. Plays an inhibitory role on the chemoreceptor trigger zone in the medulla leading to an antiemetic effect. Possess anticholinergic properties producing CNS depression.

antiemetic, antihistamine, sedative/hypnotic

phenothiazine

• IV administration may cause damage to tissue, hypertension, impaired liver function • monitor for neuroleptic malignant syndrome, confusion, sedation • may cause CNS depression • assess sedation level and anticholinergic effects

decreases excitability and slows conduction velocity through the heart

antiarrhythmic (Class IA Na Channel Blocker)

• may cause ventricular arrhythmias, seizure, asystole, heart block • monitor EKG continuously may cause widening of QRS complex • may cause hypotension keep patient supine • monitor for signs of agranulocytosis monitor CBC frequently • can cause drug induced lupus syndrome
