Trade names: Minipress
Indications: Mild to moderate hypertension, refractory CHF; treatment of BPH
Action: Blocks post-synaptic alpha-adrenergic receptors, dilating peripheral vessels; decreases contractions in smooth muscle of prostatic capsule
Contraindications: Renal disease, hypersensitivity
Precautions: pregnancy, lactation or angina pectoris
Side Effects: dizziness, drowsiness, headache, N/V, diarrhea, impotence, vertigo, urinary frequency, tinnitus, dry mouth, incontinence, abdominal discomfort
Adverse reactions: orthostatic hypotension, palpitations, tachycardia, pancreatitis
Interactions: increased hypotensive effect: other antihypertensives, nitrates, alcohol; decreased hypotensive effect: NSAIDs
Nursing Implications: Monitor I&O’s, and weight, and assess for edema daily. Monitor BP and pulse frequently during initial drug dosage adjustment, and periodically throughout treatment. For BPH: assess patient for urinary symptoms periodically.
Category: Beta 1 blocker, cardioselective beta-adrenergic antagonist, antihypertensives, antiarrhythmics.
Action: Drug blocks beta1-adrenergic receptors in the cardiac tissue
Therapeutic effects: decrease heart rate, decrease AV conduction, & decrease blood pressure.
Indication: treatment of ventricular dysrhythmias & hypertension. Unlabeled use: angina pectoris, management of anxiety & tremors.
Side effect: Dizziness, nausea, headache, hypotension, diaphoresis, fatigue, weakness, constipation or diarrhea, occasionally impotence Adverse reactions: palpitations with abrupt withdrawal, bradycardia, CHF, pulmonary edema. Life threatening: agranulocytosis, bronchospasm with high dose
Nursing Implication: Monitor BP, ECG, pulse, I&O. Assess for S&S of CHF. Before administering the med, take apical pulse. If less than 50 bpm or arrhythmia occurs, withhold the med & notify MD. Nursing Education: teach pt how to take apical pulse & take the med exactly as directed, at the same time each day, do not miss or double dose.

Trade Name: Capoten
Indications: Management of hypertension; Decreased progression of diabetic nephropathy.
Action: ACE inhibitors that blocks the conversion of angiotensin I to the vasoconstrictor angiotensin II. Lowers BP and decreases after load in pts with CHF.
Pharmacokinetics: (Absorption) 75% absorbed following oral administration (decreased by food).
Contraindications/Precautions: Hypersensitivity. Cross sensitivity among ACE inhibitors may occur.
Interactions: Excessive hypotension, hyperkalemia, increases levels and may increase the risk of lithium toxicity.
Implementation: Precipitous drop in BP during the first 1 to 3 hr following first dose may require volume expansion with NS. Administer 1 hr before meals. Tablet may be crushed and tables may have a sulfurous odor.
Trade Name: Betaloc, Betaloc Durules, Lopresor, Lopresor SR, Lopressor, Novometoprol, Toprol-XL
· Therapeutic: antianginals, antihypertensives
· Pharmacologic: beta blockers
Indications: Hypertension, Angina pectoris, Prevention of MI and decreased mortality in pts with MI
Action: Decreases blood pressure and heart rate, attacks of angina pectoris and rate of cardiovascular mortality.
· Absorption: Well after oral administration
· Distribution: crosses the blood-brain barrier
· Metabolism and Excretion: Mostly metabolized by the liver
Contraindications/Precautions: Uncompensated CHF, Pulmonary edema, Cardiogenic shock and Bradycardia or heart block
Side Effects-Adverse Reactions: Fatigue, weakness, bradycardia, CHF, pulmonary edema and hypotension.
Implementation: High Alert: IV vasoactive medications are inherently dangerous. Before administering intravenously, have a second practitioner independently check original orders and dose calculations.
