PROPRANOLOL SUMMARY
PROPRANOLOL HYDROCHLORIDE TABLETS, USP 10 mg, 20 mg, 40 mg and 80 mg
Propranolol hydrochloride is a synthetic beta-adrenergic receptor blocking agent chemically described as (+)-1-(isopropylamino)-3-(1-naphthyloxy)-2-propanol hydrochloride.
Cardiac Arrhythmias
Intravenous administration is usually reserved for life-threatening arrhythmias or those occurring under anesthesia.
- Supraventricular arrhythmias
Intravenous propranolol is indicated for the short-term treatment of supraventricular tachycardia, including Wolff-Parkinson-White syndrome and thyrotoxicosis, to decrease ventricular rate. Use in patients with atrial flutter or atrial fibrillation should be reserved for arrythmias unresponsive to standard therapy or when more prolonged control is required. Reversion to normal sinus rhythm has occasionally been observed, predominantly in patients with sinus or atrial tachycardia.
- Ventricular tachycardias
With the exception of those induced by catecholamines or digitalis, propranolol is not the drug of first choice. In critical situations when cardioversion techniques or other drugs are not indicated or are not effective, propranolol may be considered. If, after consideration of the risks involved, propranolol is used, it should be given intravenously in low dosage and very slowly, as the failing heart requires some sympathetic drive for maintenance of myocardial tone. (See DOSAGE AND ADMINISTRATION). Some patients may respond with complete reversion to normal sinus rhythm, but reduction in ventricular rate is more likely. Ventricular arrhythmias do not respond to propranolol as predictably as do the supraventricular arrhythmias. Intravenous propranolol is indicated for the treatment of persistent premature ventricular extrasystoles that impair the well-being of the patient and do not respond to conventional measures.
- Tachyarrhythmias of digitalis intoxication
Intravenous propranolol is indicated to control ventricular rate in life-threatening digitalis-induced arrhythmias. Severe bradycardia may occur. (See OVERDOSAGE).
- Resistant tachyarrhythmias due to excessive catecholamine action during anesthesia
Intravenous propranolol is indicated to abolish tachyarrhythmias due to excessive catecholamine action during anesthesia when other measures fail. These arrhythmias may arise because of release of endogenous catecholamines or administration of catecholamines. All general inhalation anesthetics produce some degree of myocardial depression. Therefore, when propranolol is used to treat arrhythmias during anesthesia, it should be used with extreme caution, usually with constant monitoring of the ECG and central venous pressure. (See WARNINGS).

| Comments: | | With propranolol the body stops reacting to the surge of adrenalin that attacks you when you get very anxious. The hands doenst shake, the legs doesnt shake, the heart doesn't pound and so on. Thus for me, it proved effective in breaking the vicious cycle where thougts start a bodily panic reaction which again fuels the thougts and so on. |
