In early presentations and large ingestions, in patients with a normal conscious state, there is a place for charcoal. In patients that require intubation, due to a depressed conscious state aim for ventilation to result in a pH 7.
Beta Blocker Effects There are a range of treatments and a progression through them, to deal with the beta effects, especially unstable haemodynamics. The range of treatments includes both chronotropes and inotropes. Crystalloid: A fluid challenge with NaSaline 0. This is a temporising measure and in most cases will not work.
Glucagon: Still appears in some texts as first line management. This can even be used as a diagnostic challenge. Adrenaline: This can work as an inotrope and chronotrope, but find it doesnt work as well.

Studies are scarce regarding how hazardous propranolol can be for pregnant women. However, the few studies that exist do not indicate that a miscarriage is one of the harmful adverse effects of this medication.
However, more studies might be required to determine it. Certain studies, specifically those of the Danish Fertility database or the Danish National Hospital Register, determines that a condition such as perinatal mortality was observed in a section of women who were exposed to the medication.
This suggests that there is quite a high chance of stillbirth as per the available statistics and analysis. There are quite a few observations made and conclusions drawn regarding birth deaths.
Women who were exposed to propranolol for quite a long period developed a few conditions such as intrauterine growth retardation, a smaller sized placenta, unforeseen foetal depression at the time of birth or conditions like bradycardia and postnatal hypoglycemia. Therefore, it is always recommended to consult your doctor before going ahead with this medication, especially during pregnancy. However, the dosage also depends on your condition and medical history.

Serious bradycardia may require temporary cardiac pacing. Studies suggest however that p-gp is not dose-limiting for intestinal absorption of propranolol in the usual therapeutic dose range.
An Established Legacy of Efficacy and Reliability
In pregnancy, there was a significant, although non-enantioselective diminution of the binding of propranolol after treatment with ethinyl estradiol. Propranolol therapy, particularly when given to infants and children, diabetic or not, has been associated with hypoglycemia especially during and as in preparation for surgery.
Inderal is not indicatedin the management of hypertensive emergencies. Antidepressants The hypotensive effects of MAO inhibitors or tricyclic antidepressants may be exacerbated when administered with beta-blockers by interfering with the beta inderal activity of site.

Hepatic Insufficiency Propranolol is extensively metabolized by the liver. In a study conducted in 6 patients with cirrhosis and 7 healthy subjects receiving mg of overdose long-acting preparation of propranolol once a day for 7 days, the steady-state propranolol concentration in patients with cirrhosis was increased 2. The inderal unit index, a composite of the number of days with headache and the associated insert of the headache, was significantly reduced for patients receiving propranolol as compared to those on placebo.
In one case, Click here result was reported after an initial dose of 5 mg propranolol.

Despite this shorter plasma half-life, propranolol peak plasma levels were 3 to 4 times higher and total plasma levels of metabolites were up to 3 times higher in these patients than in subjects with normal renal function. Chronic renal failure has been associated with a decrease in drug metabolism via down regulation of hepatic cytochrome P activity resulting in a lower "first-pass" clearance. Propranolol is not significantly dialyzable.
Hepatic Insufficiency The pharmacokinetics of Inderal LA have not been investigated in patients with hepatic insufficiency. Propranolol is extensively metabolized by the liver. In a study conducted in 6 patients with cirrhosis and 7 healthy subjects receiving mg of a long-acting preparation of propranolol once a day for 7 days, the steady-state propranolol concentration in patients with cirrhosis was increased 2.
In the patients with cirrhosis, the half-life obtained after a single intravenous dose of 10 mg propranolol increased to 7. Drug Interactions All drug interaction studies were conducted with propranolol. There are no data on drug interactions with Inderal LA capsules. No interactions were observed with either ranitidine or lansoprazole. No interaction was observed with omeprazole. Inducers of Hepatic Drug Metabolism Blood levels of propranolol may be decreased by co-administration with inducers such as rifampin, ethanol, phenytoin, and phenobarbital.
The metabolism of propranolol is reduced by co-administration of quinidine, leading to a two to three fold increased blood concentration and greater degrees of clinical beta-blockade. Propranolol does not affect the pharmacokinetics of verapamil and norverapamil.
Verapamil does not affect the pharmacokinetics of propranolol. Benzodiazepines Propranolol can inhibit the metabolism of diazepam, resulting in increased concentrations of diazepam and its metabolites. Diazepam does not alter the pharmacokinetics of propranolol.
The pharmacokinetics of oxazepam, triazolam, lorazepam, and alprazolam are not affected by co-administration of propranolol. Co-administration with aluminum hydroxide gel mg may result in a decrease in propranolol concentrations. Co-administration of metoclopramide with the long-acting propranolol did not have a significant effect on propranolol's pharmacokinetics. Propranolol did not have an effect on the pharmacokinetics of fluvastatin. Warfarin Concomitant administration of propranolol and warfarin has been shown to increase warfarin bioavailability and increase prothrombin time.
Propranolol contributed to control of diastolic blood pressure, but the magnitude of the effect of propranolol on blood pressure cannot be ascertained.
Four double-blind, randomized, crossover studies were conducted in a total of 74 patients with mild or moderately severe hypertension treated with Inderal LA mg once daily or propranolol mg given either once daily or in two 80 mg doses. Three of these studies were conducted over a 4-week treatment period. One study was assessed after a hour period. Inderal LA was as effective as propranolol in controlling hypertension pulse rate, systolic and diastolic blood pressure in each of these trials.
Angina Pectoris In a double-blind, placebo-controlled study of 32 patients of both sexes, aged 32 to 69 years, with stable angina, propranolol mg t. Twelve male patients with moderately severe angina pectoris were studied in a double-blind, crossover study. Patients were randomized to either Inderal LA mg daily or conventional propranolol 40 mg four times a day for 2 weeks.
Nitroglycerine tablets were allowed during the study. Blood pressure, heart rate and ECG's were recorded during serial exercise treadmill testing. Inderal LA was as effective as conventional propranolol for exercise heart rate, systolic and diastolic blood pressure, duration of anginal pain and ST-segment depression before or after exercise, exercise duration, angina attack rate and nitroglycerine consumption. In another double-blind, randomized, crossover trial, the effectiveness of propranolol LA mg daily and conventional propranolol 40 mg four times a day were evaluated in 13 patients with angina.
ECG's were recorded while patients exercised until angina developed. Inderal LA was as effective as conventional propranolol for amount of exercise performed, ST-segment depression, number of anginal attacks, amount of nitroglycerine consumed, systolic and diastolic blood pressures and heart rate at rest and after exercise. Migraine In a week, placebo-controlled, 4-period, dose-finding crossover study with a double-blind randomized treatment sequence, 62 patients with migraine received propranolol 20 to 80 mg 3 or 4 times daily.
The headache unit index, a composite of the number of days with headache and the associated severity of the headache, was significantly reduced for patients receiving propranolol as compared to those on placebo.
Hypertrophic Subaortic Stenosis In an uncontrolled series of 13 patients with New York Heart Association NYHA class 2 or 3 symptoms and hypertrophic subaortic stenosis diagnosed at cardiac catheterization, oral propranolol 40 to 80 mg t. Propranolol was associated with improved NYHA class for most patients. It may be used alone or used in combination with other antihypertensive agents, particularly a thiazide diuretic. Inderal LA is not indicated in the management of hypertensive emergencies.
Angina Pectoris Due to Coronary Atherosclerosis Inderal LA is indicated to decrease angina frequency and increase exercise tolerance in patients with angina pectoris. Migraine Inderal LA is indicated for the prophylaxis of common migraine headache. The efficacy of propranolol in the treatment of a migraine attack that has started has not been established, and propranolol is not indicated for such use. Therefore, when discontinuance of propranolol is planned, the dosage should be gradually reduced over at least a few weeks, and the patient should be cautioned against interruption or cessation of therapy without the physician's advice.
If propranolol therapy is interrupted and exacerbation of angina occurs, it usually is advisable to reinstitute propranolol therapy and take other measures appropriate for the management of unstable angina pectoris. Since coronary artery disease may be unrecognized, it may be prudent to follow the above advice in patients considered at risk of having occult atherosclerotic heart disease who are given propranolol for other indications.
Cardiac Failure Sympathetic stimulation may be a vital component supporting circulatory function in patients with congestive heart failure, and its inhibition by beta blockade may precipitate more severe failure. Although beta blockers should be avoided in overt congestive heart failure, some have been shown to be highly beneficial when used with close follow-up in patients with a history of failure who are well compensated and are receiving diuretics as needed.
Beta-adrenergic blocking agents do not abolish the inotropic action of digitalis on heart muscle. In Patients without a History of Heart Failure, continued use of beta blockers can, in some cases, lead to cardiac failure.
Nonallergic Bronchospasm e. Propranolol should be administered with caution in this setting since it may provoke a bronchial asthmatic attack by blocking bronchodilation produced by endogenous and exogenous catecholamine stimulation of beta-receptors. Major Surgery Chronically administered beta-blocking therapy should not be routinely withdrawn prior to major surgery, however the impaired ability of the heart to respond to reflex adrenergic stimuli may augment the risks of general anesthesia and surgical procedures.
Diabetes and Hypoglycemia Beta-adrenergic blockade may prevent the appearance of certain premonitory signs and symptoms pulse rate and pressure changes of acute hypoglycemia, especially in labile insulin-dependent diabetics. In these patients, it may be more difficult to adjust the dosage of insulin. Propranolol therapy, particularly when given to infants and children, diabetic or not, has been associated with hypoglycemia especially during fasting as in preparation for surgery.
Hypoglycemia has been reported in patients taking propranolol after prolonged physical exertion and in patients with renal insufficiency.
Thyrotoxicosis Beta-adrenergic blockade may mask certain clinical signs of hyperthyroidism. Therefore, abrupt withdrawal of propranolol may be followed by an exacerbation of symptoms of hyperthyroidism, including thyroid storm. Propranolol may change thyroid-function tests, increasing T4 and reverse T3, and decreasing T3.
Wolff-Parkinson-White Syndrome Beta-adrenergic blockade in patients with Wolff-Parkinson-White syndrome and tachycardia has been associated with severe bradycardia requiring treatment with a pacemaker. In one case, this result was reported after an initial dose of 5 mg propranolol. Inderal LA is not indicated for the treatment of hypertensive emergencies. Beta-adrenergic receptor blockade can cause reduction of intraocular pressure.
Patients should be told that Inderal LA may interfere with the glaucoma screening test. Withdrawal may lead to a return of increased intraocular pressure.
