These studies have examined the effects of dl-propranolol, d-propranolol, and metoprolol on aortic atherogenesis in the cholesterol-fed rabbit and have correlated the vascular effects of the drugs with their influence on blood pressure, plasma lipids and lipoproteins, arterial metabolism, and arterial permeability. dl-Propranolol, and, to a lesser extent, d-propranolol, used in clinically relev...

Oral propranolol is a nonselective betablocker that could play a relevant role in exudative control of retinal hemangioblastomae, as during oral propranolol treatment the size of the lesion remained stable and exudative activity was entirely inhibited. The relapse exhibited by the patient during the months in which he discontinued propranolol treatment gave rise to its reintroduction. Since the...

OBJECTIVES (1) To present six patients with symptomatic airway hemangiomas treated with oral propranolol. (2) To review the diagnostic and treatment options for airway hemangiomas and propose a new management protocol. STUDY DESIGN Retrospective review. SETTING Tertiary care children's hospital. SUBJECTS AND METHODS Pediatric patients diagnosed with obstructive airway hemangiomas treated ...

The effect of beta-adrenergic blockade with oral propranolol on resting, exercise and postexercise ventricular performance was evaluated using multiple-gated equilibrium cardiac blood and pool images in normal volunteers and patients with coronary artery disease. Propranolol produced no detectable effect on basal left ventricular function in normal subjects at doses producing intermediate (160 ...

BACKGROUND Propranolol inhalation provocation tests are used to measure indirect airways responsiveness in the investigation of asthma. In this study the effects of repeated propranolol inhalation provocation tests within the same day on normal diurnal variation in the forced expiratory volume in one second (FEV1) and subsequent propranolol airways responsiveness were investigated. METHODS Fi...

Propranolol reduces left atrial pressure at rest and during exercise in patients with mitral stenosis by lowering cardiac output and heart rate. Ten patients (aged 19-56) with moderate to severe isolated mitral stenosis were studied to determine whether propranolol increased their exercise tolerance. All were in sinus rhythm and free of left or right ventricular failure. Patients were trained i...

There is no definitive conclusion regarding the optimal timing for terminating propranolol treatment for infantile hemangioma (IH). A total of 149 patients who underwent detailed color Doppler ultrasound examination were included in this study. The characteristics and propranolol treatment of all patients were summarized and analyzed. Patients were divided into two groups according to the lesio...

Background: Beta-adrenergic blocking agents have been broadly used for treatment of many cardiovascular diseases such as arterial hypertension and ischemic heart failure. Anti-tumoral, anti-inflammatory and anti-angiogenesis effects of propranolol (a non-selective beta-adrenergic blocker) have been shown. Angiogenesis (replenish of the pre-existing vascular networks) plays a critical role in s...

Low doses of sorafenib have been shown to decrease portal pressure (PP), portal-systemic shunts, and liver fibrosis in cirrhotic rats. Nonselective beta blockers (NSBB) are the only drugs recommended for the treatment of portal hypertension. The aim of our study was to explore whether the combination of propranolol and sorafenib might show an additive effect reducing PP in cirrhotic rats. Group...
