Accumulation and Adverse Effects of Metoprolol and Propranolol After Concurrent Administration of Cimetidine

1983

Pharmacokinetics of metoprolol, propranolol and atenolol were investigated in six healthy volunteers following 7 days of oral monotherapy with these drugs and after 7 days concurrent administration of each of these betareceptor antagonists with cimetidine. Application of cimetidine did not lead to any interaction with atenolol, whereas mean peak plasma levels of metoprolol were increased by 70%, and those of propranolol by 95% due to concurrent administration of cimetidine (p < 0.05). The AUC of the two last mentioned beta blockers behaved similarly (p < 0.05). Measurement of exercise-induced tachycardia on the 6th day of administration showed no differences between monotherapy with the bet…

Providing pediatric well-care and sick visits in the COVID-19 pandemic era: the recommendations of the Italian pediatric society.

2020

AbstractPediatricians have observed a significant decrease in in-person child health visits during the COVID-19 pandemic. In the post lockdown period, the coronavirus trend remains positive in Italy but fears of a second wave have recently grown in Italy due to active hotbeds of contagion. The pandemic may negatively affect the care of pediatric patients and overall children welfare as it may present with severe signs and symptoms or it may complicate. The Italian Pediatric Society recommend to separate well visits from sick ones, to educate families and to promote hygienic strategies to provide an adequate pediatric assistance in case of a second pandemic wave.

Stimulation with carbachol alters endomembrane distribution and plasma membrane expression of intracellular proteins in lacrimal acinar cells.

2000

The events that lead to Sjogren's autoimmune processes in the lacrimal gland remain poorly understood. The acinar cell's responses to acute cholinergic stimulation include release of secretory products across the apical plasma membrane (apm) and a number of processes related to traffic between endomembrane compartments and the basal-lateral plasma membranes (blm), such as recruitment of Na, K-ATPase, accelerated recycling, and accelerated transcytosis of secretory IgA. We tested the hypothesis that stimulation-induced acceleration of endomembrane traffic is accompanied by changes in compartmentation and increased blm expression of proteins that are normally sequestered in endomembrane compa…

?-Carboline binding indicates the presence of benzodiazepine receptor subclasses in the bovine central nervous system

1982

Receptor binding studies were performed with tritiated propyl β-carboline-3-carboxylate ([3H]PrCC), tritiated ethyl β-carboline-3-carboxylate ([3H]ECC), and tritiated flunitrazepam ([3H]FNT) in membrane preparations from different regions of the bovine brain and retina. Specific binding in all regions investigated was associated with benzodiazepine receptor sites. However, not all benzodiazepine receptor sites. However, not all benzodiazepine receptors in the regions investigated as determined by the specific binding of tritiated flunitrazepam ([3H]FNT) are available for [3H]PrCC suggesting that specific [3H]PrCC binding labels only one subclass or subpopulation of the benzodiazepine recept…
