Mode of Action

• Propranolol is a non-cardioselective beta-blocker that competitively blocks beta1- and beta2-receptors resulting in decreased heart rate, myocardial contractility, BP and myocardial oxygen demand. It has membrane-stabilising properties.

Precaution

• Sinus node dysfunction, DM, history of nonallergic bronchospasm (e.g. chronic bronchitis, emphysema), myasthenia gravis, 1st degree heart block. May mask signs of hyperthyroidism and hypoglycaemia. Renal or hepatic impairment. Abrupt withdrawal may exacerbate angina symptoms or precipitate MI in patients w/ coronary artery disease. Elderly. Pregnancy and lactation. Patient Counselling Avoid cigarette smoking. Monitoring Parameters Monitor ECG, heart rate and BP.

Side Effect

• Most adverse effects have been mild and transient and have rarely required the withdrawal of therapy. Cardiovascular: Bradycardia; congestive heart failure; intensification of AV block; hypotension; paresthesia of hands; thrombocytopenic purpura; arterial insufficiency, usually of the Raynaud type. Central Nervous System: Lightheadedness; mental depression manifested by insomnia, lassitude, weakness, fatigue; reversible mental depression progressing to catatonia; visual disturbances; hallucinations; vivid dreams; an acute reversible syndrome characterized by disorientation for time and place, short-term memory loss, emotional lability, slightly clouded sensorium, and decreased performance on neuropsychometrics. For immediate formulations, fatigue, lethargy, and vivid dreams appear dose related. Gastrointestinal: Nausea, vomiting, epigastric distress, abdominal cramping, diarrhea, constipation, mesenteric arterial thrombosis, and ischemic colitis.

Interaction

• May cause additive negative chronotropic and/or inotropic effect w/ amiodarone, disopyramide, quinidine, flecainide and Ca channel blockers. May cause additive hypotensive effect w/ phenothiazines. β-adrenergic stimulating effects of sympathomimetic agents are antagonised. Concomitant admin w/ catecholamine-depleting drugs (e.g. reserpine) may cause additive effects and potentiate depression. Reduced antihypertensive effect w/ aluminium and NSAIDs. Coadministration w/ warfarin increases its bioavailability and prothrombin time. Altered antidiabetic response when used w/ antidiabetic agents and insulin. Increased risk of hypotension and attenuation of the reflex tachycardia w/ anaesth drugs. Potentially Fatal: Increased risk of QT interval prolongation and torsades de pointes w/ thioridazine.
