GABAA-receptor Subtypes: Clinical Efficacy and Selectivity of Benzodiazepine Site Ligands
1997
The main inhibitory neurotransmitter receptor of the brain, the gamma-aminobutyric acid type A receptor (GABA[A]), mediates the actions of several classes of clinically important drugs, such as benzodiazepines, barbiturates and general anaesthetics. This review summarizes the current knowledge on how classical benzodiazepines and novel nonbenzodiazepine compounds act on the benzodiazepine site of GABA(A) receptors and on their clinical pharmacology related to anxiolytic, sedative, hypnotic and cognitive effects or side-effects. Partial agonism, receptor subtype selectivity and novel binding sites are discussed as possible strategies to develop new drugs with fewer adverse effects than are s…
Palliative sedation in advanced cancer patients followed at home: A retrospective analysis
2012
Abstract CONTEXT: Data regarding palliative sedation at home in dying patients are lacking. OBJECTIVES: To describe the frequency, indication, and modality of palliative sedation (PS) in patients followed at home. METHODS: A retrospective analysis of home care cancer patients was performed. Patients who received PS before dying were selected and information about epidemiologic characteristics, indications, duration, drugs, and outcomes was collected. RESULTS: Of 370 medical charts of patients who died at home, 49 patients received PS before dying. PS was proposed by the team, relatives, or both in 63.3%, 4.1%, and 32.6% of cases, respectively. Delirium alone or in combination with other sym…
Palliative sedation in patients with advanced cancer followed at home: A systematic review
2011
Abstract Context Patients with advanced cancer who are near the end of life may experience intolerable suffering refractory to targeted palliative therapies. Palliative sedation (PS) is considered to be an effective treatment modality for these refractory symptoms when aggressive efforts fail to provide relief. Objectives The aim of this study was to systematically review articles regarding PS performed at home in patients with intractable symptoms. Methods Literature databases searched included MedLine, PubMed, and EMBASE. The text words and MeSH/EMTREE terms "home care" and "sedation" were used for electronic database searches. Results Six articles met the inclusion criteria for research …
Prediction of properties of chiral compounds by molecular topology
1998
Abstract A common assumption in chemistry is that chiral behavior is associated with 3-D geometry. However, chiral information is related to symmetry, which allows the topological handling of chiral atoms by weighted graphs and the calculation of new descriptors that give a weight to the corresponding entry in the main diagonal of the topological matrix. In this study, it is demonstrated that, operating in this way, chiral topological indices are obtained that can differentiate the pharmacological activity between pairs of enantiomers. The 50% inhibitory concentration (IC50) values of the D2 dopamine receptor and the σ receptor for a group of 3-hydroxy phenyl piperidines are specifically pr…
Clinical management of drug-drug interactions in HCV therapy: Challenges and solutions.
2013
Contains fulltext : 118153.pdf (Publisher’s version ) (Open Access) Hepatitis C virus (HCV) infected patients often take multiple co-medications to treat adverse events related to HCV therapy, or to manage other co-morbidities. Drug-drug interactions associated with this polypharmacy are relatively new to the field of HCV pharmacotherapy. With the advent of the direct-acting antivirals telaprevir and boceprevir, which are both substrates and inhibitors of the cytochrome P450 (CYP) 3A iso-enzyme, knowledge and awareness of drug-drug interactions have become a cornerstone in the evaluation of patients starting and continuing HCV combination therapy. In our opinion, an overview of conducted dr…
Prognostic value of blood lactate in critically ill patients
1984
Hyperlactatemia is frequently observed in critically ill patients. A correlation of blood lactate concentrations and outcome of patients has been proven in circulatory shock, circulatory arrest, acute myocardial infarction, acute hypnotic drug poisoning and severe pancreatitis. However, the prognostic relevance of hyperlactatemia yields from statistical examinations in larger groups of patients. It should not be misused as a reliable prognostic sign in the individual patient, but is of high value in comparing groups of patients. In individual patients, hyperlactatemia is a useful indicator pointing to the severity of illness and to superimposed complications. Blood lactate is of considerabl…
Premedication with midazolam in intellectually disabled dental patients: Intramuscular or oral administration? A retrospective study
2016
Background: The use of midazolam for dental care in patients with intellectual disability is poorly documented. The purpose of this study was to determine which method of premedication is more effective for these patients, 0.15 mg/kg of intramuscular midazolam or 0.3 mg/kg of oral midazolam. Material and Methods: This study was designed and implemented as a non-randomized retrospective study. The study population was composed of patients with intellectual disability who required dental treatment under ambulatory general anesthesia from August 2009 through April 2013. Patients were administered 0.15 mg/kg of midazolam intramuscularly (Group IM) or 0.3 mg/kg orally (Group PO). The predictor v…
Current methods of sedation in dental patients : a systematic review of the literature
2015
Objetive The main objective of this systematic literature review is to identify the safest and most effective sedative drugs so as to ensure successful sedation with as few complications as possible. Study Design A systematic literature review of the PubMed MEDLINE database was carried out using the key words “conscious sedation,” “drugs,” and “dentistry.” A total of 1,827 scientific articles were found, and these were narrowed down to 473 articles after applying inclusion and exclusion criteria. These 473 studies were then individually assessed for their suitability for inclusion in this literature review. Results A total of 21 studies were selected due to their rigorous study design and c…
Evaluation of endovenous sedation using BIS monitoring in dentistry. A systematic review
2018
Background The aim of the present review was evaluate the utility and validity of the Bispectral Index (BIS) in dental treatment carried out under endovenous sedation, and compare its efficacy with clinical sedation scales. Material and Methods Electronic and manual literature searches were conducted by two independent reviewers for articles published up to April 2017 in several databases, including Medline and Cochrane Library. Results Sixteen articles met the inclusion criteria. A correlation was identified between BIS and clinical sedation scales. A BIS range between 75 and 84 showed a high probability of corresponding to an Observer’s Assessment of Alertness and Sedation Scale (OAA/S) v…
