Chamberlain
1. Albuterol (Proventil): Indications: Asthma, COPD; used alone or in
combination with a glucocorticoid or an anticholinergic (e.g.,
ipratropium)
Mechanism of Action: Binds to beta-2 receptors in airway smooth muscle,
causing bronchodilation
Side Effects: Chest pain, palpitations, tremors, nervousness
Key Point: Short-acting; used for acute asthma attacks
2. t-PA (Alteplase)‰ : Indications: Myocardial infarction (MI),
stroke, pulmonary embolism (PE)
Mechanism of Action: Breaks down fibrinogen, promoting fibrinolysis
Side Effects: Bleeding
,Contraindications: Hemorrhagic stroke, internal bleeding, recent
trauma/surgery, severe hypertension
Key Point: Administer within 3 hours of symptom onset; limit intramuscular
(IM) injections
3. Amiodarone (Cordarone): Indications: Atrial fibrillation (Afib),
ventricular fibrillation (Vfib), ventricular tachycardia (Vtach)
Mechanism of Action: Potassium channel blocker
Side Effects: Hypotension, bradycardia, visual disturbances, gastrointestinal
(GI) upset, liver toxicity, thyroid dysfunction
Key Point: Requires monitoring due to potential organ toxicity
4. Amlodipine (Norvasc) calcium channel blockerŠ : Indications:
Hypertension, chronic stable angina
Mechanism of Action: Calcium channel blocker; inhibits calcium ion
influx into vascular smooth muscle and cardiac muscle Side Effects:
Ankle edema, dizziness, fatigue
Key Point: May cause peripheral edema; monitor for swelling
5. Aspirin: Indications: Prevention of MI and stroke
, Mechanism of Action: Inhibits platelet aggregation
Side Effects: Bleeding, tinnitus, GI upset
Contraindications: Children with fever (Reye's syndrome), patients with
bleeding disorders
Key Point: Discontinue 5-7 days before surgery
6. Atenolol (Tenormin)“ : Indications: Hypertension, angina, heart failure
(HF), MI Mechanism of Action: Beta-1 adrenergic blocker; decreases
heart rate and blood pressure
Side Effects: Bradycardia, decreased cardiac output, hypotension, fatigue,
erectile dysfunction
Key Point: Monitor blood pressure and pulse; change positions slowly
7. Atorvastatin (Lipitor): Indications: Hypercholesterolemia, prevention
of MI
Mechanism of Action: Inhibits HMG-CoA reductase, decreasing LDL and
increasing
HDL
Side Effects: Hepatotoxicity, GI upset, muscle pain, rhabdomyolysis
