Background—Postural Tachycardia Syndrome (POTS) induces disabling chronic orthostatic intolerance with an excessive increase in heart rate (HR) upon standing. Beta-blockade is an appealing treatment approach, but there are conflicting preliminary reports. We tested the hypothesis that propranolol will attenuate the tachycardia and improve symptom burden in patients with POTS. In Protocol #1, a ...

Background: Hemangioma is a benign vascular tumor that shouldbe treated in problematic situations.Propranolol efficacy, target dose, range of age, duration of treatment and complications arenot conclusive for treatment of pediatric hemangioma. Our goal was to study efficacy and safety of propranolol for hemangiomatreating in children. Methods: A randomized, open label crossover trial with two ...

Beta-adrenergic receptor blockade has been demonstrated to reduce obstruction of the left ventricular outflow tract in patients with idiopathic hypertrophic subaortic stenosis (IHSS) and has also proved helpful in reducing angina pectoris due to ischemic heart disease. Accordingly, the effects of oral propranolol on the level and duration of exercise required to produce angina in seven patients...

Infantile hemangiomas (IH) are common benign tumors in infancy, affecting 5-10% of all infants and they can still cause disfigurement and serious complications depending on their location and size, which can be associated with ulcerations and haemorrhage. Since 2008, propranolol has become the first choice of therapy for complicated IH, compared to conventional approach with systemic corticoste...

A trial of oral propranolol as a hypotensive agent was designed to provide adequate treatment periods. Twenty-eight patients with essential hypertension, with a mean blood pressure of 190/111 mm. Hg, were controlled on 120-320 mg. of propranolol daily. Their mean treated blood pressure was 153/91. They then entered, on a randomized and double-blind basis, a cross-over trial of two 16-week perio...

INTRODUCTION Several therapeutic approaches have been developed to treat choroidal hemangioma. However, all these therapies are associated with a potential risk of damaging the overlying retina. CASE REPORT We report a case of circumscribed choroidal hemangioma (CCH) in a 59-year-old man refractory to laser treatment. Visual acuity was 20/200 and a serous macular detachment was present. The C...

Whole-blood propranolol concentrations were estimated for 12 hours after a single 80 mg oral dose was given in six patients taking cimetidine and two weeks after they had stopped the drug. Mean blood propranolol concentrations were higher throughout the sampling period when the patients were taking cimetidine than when they were not, and the difference was statistically significant between one ...

Left ventricular function and exercise capacity were assessed in 79 patients randomised to receive intravenous and oral propranolol (n = 44) or conventional therapy (n = 35) within four hours of onset of their first myocardial infarction. Cineangiocardiography and exercise testing were performed four weeks after infarction to allow for maximum recovery of myocardial function. Left ventriculogra...

OBJECTIVE Hemangiomas are the most common benign vascular tumors of infancy. Although most infantile hemangiomas (IHs) have the ability to involute spontaneously after initial proliferation and resolve without consequence, intervention is required in a subset of IHs, which develop complications resulting in ulceration, bleeding, or aesthetic deformity. The primary treatment for this subset of I...

IMPORTANCE While propranolol is touted as superior to prednisolone for treating infantile hemangiomas (IH), a randomized clinical trial (RCT) comparing the outcome and tolerability of these medications for symptomatic, proliferating IH has not been reported. OBJECTIVES To determine if oral propranolol is more efficacious and better tolerated than prednisolone in treating symptomatic, prolifer...
