The impact of the EMA change in definition of "dose" on the BCS dose-solubility ratio: a review of the biowaiver monographs.
2013
The Biopharmaceutics Classification System (BCS) defines the solubility characteristics of an active pharmaceutical substance based on its dose-solubility ratio: for highly soluble drugs this ratio is less than 250 mL over a defined pH range. Prior to the revision of the European Medicines Agency (EMA, formerly EMEA) guideline in 2010, the "dose" in this ratio was consistently defined by the US FDA, the EMA, and the WHO biowaiver guidelines as the highest dosage strength. However, in the revised EMA guideline, the dose is defined as the highest single dose administered according to the Summary of Product Characteristics. The new EMA criterion for highly soluble may be closer to the actual c…
Role of ondansetron plus dexamethasone in fractionated chemotherapy.
1993
This randomised, double-blind, parallel-group study was carried out to compare the efficacy and safety profile of ondansetron plus dexamethasone and metoclopramide plus dexamethasone in patients receiving fractionated cisplatin (20-25 mg/m2/day) chemotherapy for the treatment of testicular cancer. An interim analysis of 95 patients showed that the ondansetron regimen was significantly superior compared to the metoclopramide regimen (p0.001). According to the study protocol the study was terminated at this stage. At the time the decision to stop the study was taken, a total of 113 patients had been enrolled and were evaluable on an 'intention to treat' basis. Fifty-six of these had received …
Oral granisetron with or without methylprednisolone versus metoclopramide plus methylprednisolone in the management of delayed nausea and vomiting in…
1995
Background. A single-institution, randomized open trial was prospectively performed to compare orally administered granisetron with or without intramuscularly administered methylprednisolone to metoclopramide plus methylprednisolone in the prevention of delayed nausea and vomiting induced by cisplatin-based chemotherapy. The effects of antiemetic treatments were evaluated from days 2 to 5 of the first cycle after cisplatin administration among patients who had never before received chemotherapy. Methods. All patients were treated with chemotherapeutic regimens containing cisplatin greater than or equal to 80 mg/m 2 and received antiemetic therapy with granisetron 3 mg intravenously for the …
Study of abnormal adrenal receptors in subjects with ACTH-independent Cushing's syndrome and nodular adrenal hyperplasia
2020
ACTH-independent Cushing's Syndrome (AICS) accounts for 15-20% of cases of Cushing's syndrome, with1% due to abnormal receptors. Our aim is to study the presence of abnormal receptors in subjects diagnosed with AICS with nodular adrenal hyperplasia in a 14-year period (2002-2016), as well as its clinical-biological and evolutive characteristics.A multicentre descriptive study of a 15-case series of AICS with nodular adrenal hyperplasia (study period: 2002-2016). In these cases, abnormal receptor screening was performed by means of stimulation tests, with a plasma cortisol increase of ≥ 25% from baseline being considered pathologic.Of the 15 cases, 13 were female, with a mean age at diagnosi…
Stratified Care vs Step Care Strategies for Migraine
2000
ContextVarious guidelines recommend different strategies for selecting and sequencing acute treatments for migraine. In step care, treatment is escalated after first-line medications fail. In stratified care, initial treatment is based on measurement of the severity of illness or other factors. These strategies for migraine have not been rigorously evaluated.ObjectiveTo compare the clinical benefits of 3 strategies: stratified care, step care within attacks, and step care across attacks, among patients with migraine.Design and SettingRandomized, controlled, parallel-group clinical trial conducted by the Disability in Strategies Study group from December 1997 to March 1999 in 88 clinical cen…
Aggressive Pharmacological Treatment for Reversing Malignant Bowel Obstruction
2004
Early and intensive pharmacological treatment not only may reduce gastrointestinal symptoms but also reverse malignant bowel obstruction. Fifteen consecutive advanced cancer patients with inoperable bowel obstruction received a combination of drugs including metoclopramide, octreotide, dexamethasone and an initial bolus of amidotrizoato. Recovery of intestinal transit was reported within 1-5 days in fourteen patients, who continued this treatment without presenting symptoms of bowel obstruction until death. This case series establishes that the combination of propulsive and antisecretive agents can act synergistically to allow a fast recovery of bowel transit without inducing unpleasant col…
Metoclopramide and diphenhydramine in the treatment of hyperemesis gravidarum: effectiveness and predictors of rehospitalisation.
2007
Abstract Objectives Hyperemesis gravidarum (HG) is the second most common reason for hospitalisation during pregnancy. Since 2002, a new HG treatment protocol consisting of metoclopramide plus diphenhydramine was put in place at CHU Sainte-Justine, affiliated to University of Montreal, Quebec, Canada. The objectives of this study were to evaluate the effectiveness of this new HG protocol regarding length of hospitalisation for HG, rate of rehospitalisation, evolution of nausea and vomiting symptoms, and rate of adverse events. Study design A retrospective cohort study was conducted from 2002 to 2006 on the population of pregnant women diagnosed with HG, and treated at CHU Sainte-Justine wit…
5-HT3 receptor-channels coupled with Na+ influx in human T cells: role in T cell activation.
1999
The study was conducted on a human (Jurkat) T cell line, loaded with a Na+ fluorescent probe, SBFI/AM. Serotonin and an agonist of 5-HT3 receptor-channels, 2-methyl-5HT, evoked Na+ influx, whereas the agonists of other serotonergic receptor subtypes, i.e., 5-HT1A and 5-HT1B receptors, failed to induce Na+ influx in these cells. By using 3H-BRL43694, an agonist of 5-HT3 receptor-channels, we characterized 5-HT3 lymphocyte receptors which exhibited a density (Bmax) of 300 +/- 20 fmol/10(6) cells and a Kd of 30 nM in Jurkat T cells. The T-cell 5-HT3 receptor-channel is not regulated either by the protein kinase C or by the free intracellular calcium concentrations as the agents known to activa…
Flow injection-spectrophotometric determination of metoclopramide hydrochloride.
1997
Abstract The determination of metoclopramide hydrochloride is spectrophotometrically determined by the Bratton-Marshall method in a flow injection assembly. The required nitrite is prepared on-line in the flow assembly by reducing a nitrate solution with the aid of a copperised cadmium solid-phase reactor. The calibration graph is linear over the range 0.5–85 mg l−1, with a relative standard deviation (RSD) of 0.89%, and sample throughput of 51 samples h−1. The method is easy and simple, and it is applied to determination of metoclopramide in some pharmaceutical formulations. The method eliminates the need for frequent preparation of unstable nitrite solutions.
Gender and anthropometrics of patients undergoing cisplatin-containing chemotherapy as determinants of acute emesis over repeat courses
2002
Objective. To characterize the anthropometric and pharmacotherapeutic variables related to acute emesis over repeat courses of cisplatin-containing regimens (≥50 mg/m survival analysis.2) by means of survival analysis. Methods. A prospective, cross-sectional non-controlled study was started to analyse acute vomiting in patients treated in a general hospital. The patients received an intravenous combination of drugs based on metoclopramide (two 3 mg/kg doses), diphenhydramine (20 mg) and dexamethasone (20 mg) as first choice antiemetic treatment. An intravenous regimen based on ondansetron (8 mg) and dexamethasone (20 mg) was given as an alternative regimen. Therapeutic failure was defined …
