Inderal XL
Overview
What is Inderal XL?
INDERAL XL contains propranolol hydrochloride, a nonselective, beta-adrenergic receptor-blocking agent for oral administration, as an extended-release product. INDERAL XL is available as 80 mg and 120 mg capsules which contain sustained-release beads. Each of the beads contains propranolol hydrochloride and is coated with dual membranes. These membranes are designed to retard release of propranolol hydrochloride for several hours after ingestion followed by the sustained release of propranolol.
The active ingredient in INDERAL XL is a synthetic beta-adrenergic receptor-blocking agent chemically described as 1-(Isopropylamino)-3-(1-naphthyloxy)-2-propanol hydrochloride. Its structural formula is:
Propranolol hydrochloride is a stable, white, crystalline solid, which is readily soluble in water and ethanol. Its molecular weight is 295.81. Each capsule for oral administration contains sugar spheres, ethylcellulose, povidone, hypromellose phthalate, diethyl phthalate, hypromellose, polyethylene glycol, gelatin, titanium dioxide. The ink contains FD&C Blue #2 Aluminum Lake. In addition, INDERAL XL 120 mg capsules contain yellow iron oxide.

How should I use Inderal XL?
INDERAL XL is indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes, including beta-blockers.
Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than one drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program’s Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC).
Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly.
Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mm Hg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal.
Some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease). These considerations may guide selection of therapy.
INDERAL XL should be administered once daily at bedtime and should be taken consistently either on an empty stomach or with food. Initiate dosing at 80 mg and titrate to 120 mg daily as needed for blood pressure control. Doses above 120 mg have no additional effects on blood pressure . The time needed for full antihypertensive response is variable, but is usually achieved within 2 to 3 weeks.

What might happen if I take too much Inderal XL?
Most overdoses of propranolol are mild and respond to supportive care.
Propranolol is not significantly dialyzable.
Hypotension and bradycardia have been reported following propranolol overdose and should be treated appropriately. Glucagon can exert potent inotropic and chronotropic effects and may be particularly useful for the treatment of hypotension or depressed myocardial function after a propranolol overdose.
Glucagon should be administered as 50-150 mcg/kg intravenously followed by continuous drip of 1-5 mg/hour for positive chronotropic effect. Isoproterenol, dopamine or phosphodiesterase inhibitors may also be useful. Epinephrine, however, may provoke uncontrolled hypertension. Bradycardia can be treated with atropine or isoproterenol. Serious bradycardia may require temporary cardiac pacing.
Monitor the electrocardiogram, pulse, blood pressure, neurobehavioral status and intake and output balance. Isoproterenol and aminophylline may be used for bronchospasm.

Clinical Information
Chemical Structure
No Image foundClinical Pharmacology
The mechanism of the antihypertensive effect of propranolol has not been established. Among factors that contribute to the antihypertensive action are: (1) decreased cardiac output, (2) inhibition of renin release by the kidneys, and (3) diminution of tonic sympathetic nerve outflow from vasomotor centers in the brain. Although total peripheral resistance may increase initially, it readjusts to or below the pretreatment level with chronic use. Effects of propranolol on plasma volume appear to be minor and somewhat variable.
Non-Clinical Toxicology
INDERAL XL is contraindicated in patients with:Following abrupt discontinuation of therapy with beta-blockers, exacerbations of angina pectoris and myocardial infarction have occurred.
When discontinuing chronically administered INDERAL XL, particularly in patients with ischemic heart disease, gradually reduce the dose over a period of 1-2 weeks and monitor the patients. If angina markedly worsens or acute coronary insufficiency develops, promptly resume therapy, at least temporarily and take other measures appropriate for the management of unstable angina. Warn patients against interruption or discontinuation of therapy without physician’s advice.
Because coronary artery disease is common and may be unrecognized, avoid abrupt discontinuation of INDERAL XL therapy even in patients treated only for hypertension.
