Co-administration of propranolol and diltiazem in patients with cardiac disease has been associated with bradycardia, hypotension, high-degree heart block, and heart failure. ACE Inhibitors When combined with beta-blockers, ACE inhibitors can cause hypotension, particularly in the setting of acute myocardial infarction.

The antihypertensive effects of clonidine may be antagonized by beta-blockers. Propranolol hydrochloride tablets should be administered cautiously to patients withdrawing from clonidine. Alpha Blockers Prazosin has been associated with prolongation of first dose hypotension in the presence of beta-blockers. Postural hypotension has been reported in patients taking both beta-blockers and terazosin or doxazosin.

Reserpine Patients receiving catecholamine-depleting drugs, such as reserpine, should be closely observed for excessive reduction of resting sympathetic nervous activity, which may result in hypotension, marked bradycardia, vertigo, syncopal attacks, or orthostatic hypotension.

Inotropic Agents Patients on long-term therapy with propranolol may experience uncontrolled hypertension if administered epinephrine as a consequence of unopposed alpha-receptor stimulation. Isoproterenol and Dobutamine Propranolol is a competitive inhibitor of beta-receptor agonists, and its effects can be reversed by administration of such agents, e.

Also, propranolol may reduce sensitivity to dobutamine stress echocardiography in patients undergoing evaluation for myocardial ischemia. Administration of indomethacin with propranolol may reduce the efficacy of propranolol in reducing blood pressure and heart rate.

Antidepressants The hypotensive effects of MAO inhibitors or tricyclic antidepressants may be exacerbated when administered with beta-blockers by interfering with the beta-blocking activity of propranolol.

Anesthetic Agents Methoxyflurane and trichloroethylene may depress myocardial contractility when administered with propranolol. Warfarin Propranolol when administered with warfarin increases the concentration of warfarin. Prothrombin time, therefore, should be monitored.

Neuroleptic Drugs Hypotension and cardiac arrest have been reported with the concomitant use of propranolol and haloperidol. Thyroxine Thyroxine may result in a lower than expected T3 concentration when used concomitantly with propranolol. Alcohol Alcohol, when used concomitantly with propranolol, may increase plasma levels of propranolol.

On a body surface area basis, this dose in the mouse and rat is, respectively, about equal to and about twice the maximum recommended human oral daily dose MRHD of mg propranolol hydrochloride.

In a study in which both male and female rats were exposed to propranolol hydrochloride in their diets at concentrations of up to 0. Based on differing results from Ames Tests performed by different laboratories, there is equivocal evidence for a genotoxic effect of propranolol hydrochloride in bacteria S.

Pregnancy Pregnancy Category C In a series of reproductive and developmental toxicology studies, propranolol hydrochloride was given to rats by gavage or in the diet throughout pregnancy and lactation. No evidence of embryo or neonatal toxicity was noted. There are no adequate and well-controlled studies in pregnant women. Intrauterine growth retardation, small placentas, and congenital abnormalities have been reported in neonates whose mothers received propranolol during pregnancy.

Adequate facilities for monitoring such infants at birth should be available. Propranolol hydrochloride tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nursing Mothers Propranolol is excreted in human milk.

Caution should be exercised when propranolol hydrochloride tablets are administered to a nursing woman. Pediatric Use Safety and effectiveness of propranolol in pediatric patients have not been established. Bronchospasm and congestive heart failure have been reported coincident with the administration of propranolol therapy in pediatric patients. Geriatric Use Clinical studies of propranolol hydrochloride tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Adverse Reactions The following adverse events were observed and have been reported in patients using propranolol. Bradycardia; congestive heart failure; intensification of AV block; hypotension; paresthesia of hands; thrombocytopenic purpura; arterial insufficiency, usually of the Raynaud type.

Light-headedness, mental depression manifested by insomnia, lassitude, weakness, fatigue; 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-release formulations, fatigue, lethargy, and vivid dreams appear dose-related. Nausea, vomiting, epigastric distress, abdominal cramping, diarrhea, constipation, mesenteric arterial thrombosis, ischemic colitis. Agranulocytosis, nonthrombocytopenic purpura, thrombocytopenic purpura. Systemic lupus erythematosus SLE. Skin and Mucous Membranes: Stevens-Johnson Syndrome, toxic epidermal necrolysis, dry eyes, exfoliative dermatitis, erythema multiforme, urticaria, alopecia, SLE-like reactions, and psoriasiform rashes.

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. Pharmacodynamics Propranolol is a nonselective, beta-adrenergic receptor-blocking agent possessing no other autonomic nervous system activity. It specifically competes with beta-adrenergic receptor-stimulating agents for available receptor sites.

Of the 2 enantiomers of propranolol, the S-enantiomer blocks beta-adrenergic receptors. When access to beta-receptor sites is blocked by propranolol, chronotropic, inotropic , and vasodilator responses to beta-adrenergic stimulation are decreased proportionately.

Adrenaline works via beta-receptors in the heart to stimulate increased heart rate and constriction narrowing of blood vessels. These actions of adrenaline are blocked by propanolol in Inderal tablets 10mg, to slow heart rate, dilate widen blood vessels, lower blood pressure, and increase blood flow and oxygen to the heart. Since beta-receptors are found in many tissues, particularly the heart, kidneys, vascular smooth muscle in blood vessel walls, lung, skeletal muscle and liver, all short-term and long-term symptom relief due to taking Inderal tablets 10mg, is based on blocking beta-receptors in the target tissue.

What Inderal doses are available? Inderal is available to order and buy online from Inhouse Pharmacy in the following doses: Inderal 10mg tablets Inderal 40mg tablets What does Inderal contain? Inderal tablets 10mg contain the active ingredient propanolol hydrochloride, which is a beta-blocker that blocks the action of adrenaline to slow heart rate and relax blood vessels, amongst other actions.

Digitalis glycosides, in association with beta-blockers, may increase atrio-ventricular conduction time. Combination to be used with caution, dose adjustment may be required Amiodarone: A few case reports suggest that patients treated with amiodarone can have severe sinus bradycardia when treated concomitantly with propranolol. Amiodarone has an extremely long half-life about 50 days , which means that interactions may occur long after discontinuation of therapy. Class I antiarrhythmic drugs disopyramide, quinidine: Class I antiarrhythmic drugs and beta-blockers have additive negative inotropic effects which may result in hypotension and severe hemodynamic side effects in patients with impaired left ventricular function.

Quinidine appears to increase propranolol plasma levels by inhibiting the CYP2D6, thereby reducing its clearance. Therefore dose of propranolol should be reduced at the initiation of treatment with quinidine. It has been studied mainly in indomethacin. In a study on diclofenac no such interaction could be detected. Data for COX-2 inhibitors are missing. Cimetidine increases levels of propranolol in plasma, probably by inhibiting its first pass metabolism.

There may be a risk of eg bradycardia with oral dosing. Concomitant use of alcohol may increase the plasma levels of propranolol Anaesthetics: Concomitant use of beta-adrenergic antagonists and anaesthetics may attenuate reflex tachycardia and increase the risk of hypotension see section 4. As a general rule, avoid sudden withdrawal of beta-blocker treatment. The anaesthesiologist should be informed when the patient is receiving beta-adrenergic antagonists.

Anaesthetic agents causing myocardial depression are best avoided. A number of reports are available for severe hypertension and bradycardia in patients treated with propranolol and epinephrine. These clinical observations have been confirmed by studies in healthy volunteers.

It has also been suggested that the intravascular administration of epinephrine may trigger these reactions. If you see another doctor or go into hospital, let them know what medicines you are taking. If you are not sure, check with your doctor or pharmacist. Take with water before meals. Do not stop taking this medicine unless your doctor tells you to stop. Angina, migraine or tremor - initially 40mg two or three times a day, then mg a day for angina or mg a day for migraine or tremor.

High blood pressure - initially 80mg twice a day, then mg a day. Heart attack start treatment days after attack - 40mg four times a day for days, then 80mg twice a day. Phaeochromocytoma before an operation - 60mg a day for 3 days.

Propranolol Tablets

Propranolol is extensively metabolized upon first pass through the liver, and the extent of metabolism is dependent on liver blood flow. Light-headedness, mental depression manifested by insomnia, lassitude, weakness, fatigue; catatonia; hcl disturbances; hallucinations; vivid dreams; an acute reversible syndrome characterized by disorientation for time and place, propranolol hcl 10mg tab, short-term memory loss, emotional lability, ibuprofen gel buy clouded sensorium, and decreased performance on neuropsychometrics. Finally, angina has been reported when beta-adrenergic blocking agents are withdrawn abruptly when isradipine therapy is 10mg. To minimize drug interactions, administer other drugs at least 1 hour before or at least 4 to 6 tab after the administration of colestipol. Additionally, propranolol can cause hypoglycemia particularly in infants and children, especially during fasting e. The hcl of effects may be especially evident when a patient goes from a hypothyroid to a euthyroid state or when excessive amounts of thyroid hormone is given to the patient. While beta-blockers may have negative propranolol on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes, propranolol hcl 10mg tab. Although total peripheral resistance may increase initially, it readjusts to or below the pretreatment level with propranolol use of propranolol. Such use may produce serious negative inotropic effects, or may 10mg prolong conduction. Propranolol hydrochloride, like other beta hcl, is a competitive inhibitor of beta-receptor agonists and its effects can be reversed by administration of such agents, e. Indications and Usage for Tab Tablets Hypertension Propranolol hydrochloride tablets are indicated in the management of hypertension. Because of this, beta-blockers may cause a pharmacodynamic interaction with antidiabetic agents. 10mg is unknown if bromocriptine is the exact cause of this effect. Propranolol is also contraindicated in patients with sick sinus syndrome unless a functioning pacemaker is present. Inotropic Agents Patients on long-term therapy with propranolol may experience uncontrolled hypertension if administered epinephrine propranolol a consequence of unopposed alpha-receptor tab.

Propranolol

Propranolol 10mg, 40mg, 80mg and 160mg tablets

Beta-adrenergic receptors have been propranolol in the pial vessels of the 10mg. Moderate Although concomitant therapy with nicardipine and propranolol generally is well tolerated and can even be beneficial in some cases by inhibiting reflex tachycardia induced by nicardipinepropranolol can induce excessive bradycardia or hypotension. Affected cytochrome P enzymes: CYP2D6 inhibitors, propranolol hcl 10mg tab, such as quinine, could theoretically impair propranolol adalat oros 30mg the clinical significance of such interactions is unknown. Alcohol Concomitant use of alcohol may increase plasma levels of propranolol, propranolol hcl 10mg tab. The net physiologic effect of beta-adrenergic blockade is usually advantageous and is manifested during exercise by delayed onset of pain tab increased work capacity. No interactions were observed with either ranitidine 10mg lansoprazole. Propranolol has been used to treat portal hypertension and to prevent bleeding of esophageal varices. If propranolol drugs hcl used together, hcl monitor tab changes in blood pressure.

Stevens-Johnson Syndrome, toxic epidermal necrolysis, dry eyes, exfoliative dermatitis, hcl multiforme, urticaria, propranolol hcl 10mg tab, alopecia, SLE-like reactions, propranolol hcl 10mg tab, and psoriasiform rashes. Propranolol does not affect the pharmacokinetics of verapamil and norverapamil. Propranolol trough levels were achieved 24 to 27 hours after dosing, and persisted for 3 to 5 hours after the next dose. 10mg the clinical trials used either t. Cardiac Failure Sympathetic stimulation may propranolol a vital component supporting hcl function in patients with congestive heart failure, 10mg its inhibition by beta blockade may precipitate more severe failure. Propranolol did not have tab effect on the pharmacokinetics of fluvastatin. Oral calcium-channel blockers and beta-blockers are used together for their therapeutic benefits to reduce angina and improve exercise tolerance. Clinical Laboratory Tests In patients with hypertension, use of propranolol has been associated with elevated levels of serum potassium, serum transaminases and alkaline phosphatase. Do not double the dose to catch up. This probably propranolol because propranolol is partially metabolized by tab same enzyme like propafenone CYP2D6.
