Noradrenalin modulates prefrontal function, such as working memory (WM), and is associated with enhanced distractibility, and enhanced memory for emotional events and stimuli. The beta-blocker propranolol has been shown to reduce memory for emotional stimuli. Herein we describe investigations aimed at assessing whether the administration of propranolol would reduce the interference by emotional...
BACKGROUND Oral propranolol is widely prescribed as first-line treatment for infantile haemangiomas (IHs). Anecdotally, prescribing practice differs widely between centres. OBJECTIVES The Propranolol In the Treatment of Complicated Haemangiomas (PITCH) Taskforce was founded to establish patterns of use of propranolol in IHs. METHODS Participating centres entered data on all of their patient...
Propranolol Treatment for Infantile Hemangiomas: Short-Term Adverse Effects and Follow-Up to Age Two
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...
Background: There is a direct correlation between ocular vascular endothelial growth factor (VEGF) level and progression of pathological outcomes in diabetic retinopathy. In our previous study, the periocular administration of propranolol and celecoxib could significantly reduce ocular VEGF levels in a diabetic mouse model. Here, we investigated the changes of serum VEGF after ...
The beta-adrenergic blocker propranolol given within hours of a psychologically traumatic event reduces physiologic responses during subsequent mental imagery of the event. Here we tested the effect of propranolol given after the retrieval of memories of past traumatic events. Subjects with chronic post-traumatic stress disorder described their traumatic event during a script preparation sessio...
The effects of propranolol on whole body oxygen consumption and blood oxygen content were measured in the dog during extreme hypoxic conditions. At 9% inspired oxygen four of eight control animals died within 40 min. An identical second group was pretreated with propranolol and none died during the same hypoxic stress. Hypoxia decreased oxygen consumption in both groups, but the decrease was le...
The effect of propranolol on the electric stimulation of rat isolated diaphragm shOwed the depression of its isometric force of contraction. This depressant effect of propranolol on the rat isolated diaphragm was produced in doses much higher than the doses required for the beta adrenergic receptor blocking activity. Isoprenaline showed no effect on the rat isolated diaphragm and it did not ant...
Propranolol, a beta-adrenergic receptor antagonist, also inhibits phosphatidate phosphohydrolase, the enzyme that converts phosphatidic acid into diacylglycerol. This latter effect has prompted recent use of propranolol in studies examining the importance of diacylglycerol and phosphatidic acid in cellular signalling events. Here, we show that propranolol is also an inhibitor of protein kinase ...
OBJECTIVES To report the efficacy of propranolol as first-line treatment of head and neck hemangiomas in children and to present an optimized protocol for treating hemangiomas. DESIGN Multi-institutional retrospective study. SETTING Two tertiary care referral pediatric centers. PATIENTS Thirty-nine children with head and neck infantile hemangiomas were treated. MAIN OUTCOME MEASURES Rev...
