Gelatin A microspheres of propranolol hydrochloride for intranasal systemic delivery were developed with the aim to avoid fi rst pass metabolism, to improve the patient compliance, to use an alternative therapy to conventional dosage form, to achieve controlled blood level profi les, and to improve the therapeutic effi cacy of propranolol hydrochloride in the treatment of various cardiovascular...

A 69-year-old man had been suffering from recurrent syncope induced by laughter since the age of 58. His syncope was reproduced by head-up tilt testing with isoproterenol infusion and we concluded that his laughter-induced syncope was one type of neurally mediated syndrome (NMS). His daughter also had NMS and her syncope was treated with propranolol. Propranolol and midodrine hydrochloride, an ...

Experiments with electrophysiology of the heart have been essential for the progress in diagnostics and pharmacotherapy of cardiovascular diseases. The aim of the study was to establish the influence of a new propranolol analogue on mechanical and bioelectrical activity of the rabbit heart in vitro. In the experiment, propranolol (1-isopropylamino-3-[1-naphthoxy]-2-propanol hydrochloride) and i...

BACKGROUND New medication is needed to treat essential tremor. Preliminary evidence suggests that gabapentin may be effective in the treatment of this disorder. OBJECTIVE To study the effects of gabapentin in a comparative, double-blind, crossover, placebo-controlled trial of patients who have essential tremor. PATIENTS AND METHODS 16 patients with essential tremor (6 with a new onset and 1...

Propranolol has been found to have a protective effect in experimental myocardial ischemia. Protection of ischemic kidneys was subsequently demonstrated following treatment with propranolol and its weaker beta blocking isomer, d-propranolol. The objective of the present investigation was to study the effects of propranolol (i.e., racemic d,1 mixture) and d-propranolol upon regional cerebral blo...

Objective(s): The purpose of the present study was to prepare and to evaluate a novel niosome as transdermal drug delivery system for propranolol hydrochloride and to compare the in vitro efficiency of niosome by either thin film hydration or hand shaking method. Materials and Methods: Niosomes were prepared by Thin Film Hydration (TFH) or Hand Shaking (HS) method. Propranolol niosomes were pre...

used in the treatment of hypertension, angina pectoris, pheochromocytoma and cardiac arrhythmias (1). Because of its relatively short plasma half-life, patients are routinely asked to take propranolol hydrochloride in divided daily doses, once every 6 to 8 h. Such frequent drug administration may reduce patient compliance and therapeutic efficacy (2). In recent years, slow or sustained release ...

Beta receptor adrenergic blocking agents produce a fall of systemic arterial blood pressure which has been attributed to interference with the function of sympathetic nerves to the heart (1). While pronethalol and propranolol are known to have a peripheral vasodilator component of action which contributes to their hypo tensive effect (2, 3), it has not been determined if the more recently synth...

T he main abnormality of the uveal tract in patients with Sturge-Weber syndrome is diffuse choroidal hemangioma (DCH). Diffuse choroidal hemangioma can lead to a total retinal detachment and secondary neovascular glaucoma. Radiotherapy and photodynamic therapy are currently the preferred methods of treatment. Low-dose lens-sparing radiotherapy or proton beam irradiation can induce tumor regress...
