BACKGROUND: β-Blockers reduce temporomandibular joint (TMJ) pain. We asked whether they also reduce TMJ inflammation and, if so, whether this anti-inflammatory effect contributes to its analgesic action. METHODS: We measured many parameters of the inflammatory response after co-administration of the β-blocker propranolol with the inflammatory agent carrageenan in the TMJ of female rats. We also hypothesized that the activation of β-adrenoceptors in the TMJ induces nociception mediated, at least in part, by the inflammatory response...

REVIEW
Denise M Adams, Kiersten W Ricci
Infantile hemangiomas (IHs) are benign vascular tumors of infancy most common in the region of the head and neck. Infantile hemangiomas are common; but they are extremely heterogeneous and cause a range of complications depending on their morphology, size, or location. Medical interventions for high-risk patients include topical and systemic therapies, including oral propranolol, which has revolutionized the management of IHs over the past recent years. In the following article, the authors aim to provide a review of the natural history, pathology, complications, syndromes, and medical management of infantile hemangioma...

REVIEW
David H Darrow
Infantile hemangiomas (IHs) of the airway are far less common than their cutaneous counterparts, and their symptoms mimic those of viral croup. As a result, by the time these lesions are diagnosed, they are often advanced and causing airway compromise. Fortunately, the evolution of propranolol as an effective and safe pharmacotherapy has simplified management of IH and reduced the likelihood of complications previously seen with steroid therapy and surgery. Nevertheless, the otolaryngologist must be prepared with an alternate plan to manage lesions refractory to pharmacotherapy...

Background: Carvedilol is used in the management of hypertension, ischemic heart disease, heart failure and most recently, portal hypertension. It has been associated with improved outcomes regarding variceal bleeding, hepatic decompensation and death when compared to propranolol and endoscopic band ligation. The main cause of portal hypertension is cirrhosis and therefore carvedilol is increasingly used in these patients. Due to its extensive hepatic metabolism, carvedilol is contraindicated in severe hepatic impairment...

BACKGROUND: Variceal bleeding is a major complication of portal hypertension, which is associated with significant mortality. Moreover, patients surviving a variceal bleeding episode have very high risk of rebleeding, which is associated with mortality as high as that of the first bleed. Because of this, prevention of bleeding from gastroesophageal varices has been one of the main therapeutic goals since the advent of the first effective therapies for portal hypertension. AIM: This review deals with the present day state-of-the-art pharmacological prevention of variceal bleeding in primary and secondary prophylaxis...

Tolerance to the analgesic effect of morphine is a major clinical problem which can be managed by co-administration of another drug. This study investigated the ability of propranolol to potentiate the antinociceptive action of morphine and the possible mechanisms underlying this effect. Antinociception was assessed in three nociceptive tests (thermal, hot plate), (visceral, acetic acid), and (inflammatory, formalin test) in mice and quantified by measuring the percent maximum possible effect, the percent inhibition of acetic acid-evoked writhing response, and the area under the curve values of number of flinches for treated mice, respectively...

A new chromatographic procedure was proposed for the separation of propranolol (PRN) enantiomers based upon enantioselective chiral ligand-exchange chromatography. The separation was carried out on a short C8 column leading to considerably short separation time. L-alanine and Cu2+ were applied as chiral selector and central bivalent complexing ion, respectively. It was found that the kind of copper salt could influence the enantioseparation efficiency. The separation on the C8 stationary phase was more efficient than that on the C18 column...

Yukako Tsutsui, Katsuhisa Sunada
Hypertensive patients receiving nonselective β-adrenergic antagonists are vulnerable to hypertension and bradycardia when injected with dental local anesthetic formulations containing epinephrine. Dexmedetomidine (DEX), an α2-adrenergic agonist, has been reported to prolong and enhance the local anesthetic effects of lidocaine. The cardiovascular effects of the DEX-lidocaine combination have not yet been investigated in the presence of nonselective β-adrenergic antagonists. Therefore, we assessed the cardiovascular effects of the DEX-lidocaine combination in spontaneously hypertensive rats (SHR) treated with a nonselective β-adrenergic antagonist (propranolol)...

Infantile hemangioma (IH) is the most common benign tumor of childhood, with a prevalence of 4 % to 10 %. It is characterized by a proliferative rapid growth phase, which starts after a few weeks of life, followed by a slow regression phase. In IH cases that are potentially disfiguring or life-threatening (10 % to 15 % of all cases), systemic therapy should be promptly initiated. Data source The present study reviews published scientific articles available in reliable electronic databases. Selected were all studies that evaluated the pathogenesis of IH and the mechanisms of action of propranolol...

Infantile hemangioma (IH) is a benign pediatric tumor, and rapid growth of IH can result in serious morbidity and even mortality. Only one drug Hemangeol™ (propranolol hydrochloride oral solution) has been approved for the treatment of IH, whereas patients suffer from its adverse effects and high frequency of administration. We have used urea, an organic compound and a normal body metabolite, in the treatment of IH for 20 years, and demonstrated that urea is an effective and well-tolerated treatment for IH...

The objective of this study is to test the hypothesis that increased muscle mass has positive effects on cardiovascular function. Specifically, we tested the hypothesis that increases in lean body mass caused by deletion of myostatin improves cardiac performance and vascular function. Echocardiography was used to quantify left ventricular function at baseline and after acute administration of propranolol and isoproterenol to assess β-adrenergic reactivity. Additionally, resistance vessels in several beds were removed, cannulated, pressurized to 60 mmHg and reactivity to vasoactive stimuli was assessed...
