Several pathologies, such as pain and inflammation, are modulated by different pathways, making it necessary to develop drugs capable of modulating different pathways. Based on that, we investigated the antinociceptive and anti-inflammatory effect of 3-(4-chlorophenylselanyl)-1-methyl-1H-indole (CMI), as well as the systems involved in these actions. This study evaluated the antinociceptive and anti-inflammatory effects of CMI [0.0001-10mg/kg administered intragastrically (i.g.)] in the formalin, glutamate, hot plate, ear edema induced by croton oil and paw edema induced by formalin tests...

Drug-induced QT interval prolongation is the most frequent cause of Long QT syndrome (LQTS) in the clinical practice. This electrophysiological entity, produced by an extended duration of the myocardial repolarization and reflected as a prolonged QT interval in the superficial electrocardiogram (EKG), increases the risk of polymorphic ventricular tachycardia (Torsades de Pointes) appearance and sudden death. Certain antiarrhythmic drugs such as amiodarone, sotalol, quinidine, procainamide, verapamil and diltiazem are known as drugs that, due to their mechanism of action, prolong the QT interval, demanding constant monitorization...

PURPOSE: The mechanisms underlying repolarization abnormalities during pregnancy are not fully understood. Although maternal serotonin (5-hydroxytryptamine, 5-HT) production is an important determinant for normal fetal development in mice, its role in mothers remains unclear. We evaluated the role of serotonin in ventricular repolarization in mice hearts via 5Htr3 receptor (Htr3a) and investigated the mechanism of QT-prolongation during pregnancy. MATERIALS AND METHODS: We measured current amplitudes and the expression levels of voltage-gated K⁺ (Kv) channels in freshly-isolated left ventricular myocytes from wild-type non-pregnant (WT-NP), late-pregnant (WT-LP), and non-pregnant Htr3a homozygous knockout mice (Htr3a(-/-)-NP)...

Postoperative nausea and vomiting (PONV) can be very debilitating for surgical patients, and effective management reduces potential morbidity, aiding in patient satisfaction, and minimizing the need for unintended hospital stays. Risk factors include female sex, nonsmoker, and having a previous history of motion sickness or PONV. Anesthetic risk factors include receiving opioids, not receiving a total intravenous anesthetic (TIVA), exposure to nitrous oxide, and extended length of anesthetic. Many treatments, including serotonin antagonists, dopamine antagonists, corticosteroids, inhaled isopropyl alcohol, and anticholinergics, as well as techniques such as TIVA, have been utilized over recent decades in an attempt to reduce PONV incidence...

Orodispersible films (ODF) have clinical potential as extemporaneous pharmacy preparations for individualized pharmacotherapy. However, the conventional method of ODF preparation using a film applicator may limit its application, due to content uniformity challenges arising from viscosity changes of the casting solution and varied operator manipulation. This study proposes the unit-dose (UD) plate as an alternative to the film applicator for compounding individual ODFs. Using a design-of-experiments approach, we developed an extemporaneous ODF formulation for an antiemetic drug, ondansetron hydrochloride dihydrate (OND), at a clinically relevant dose...

BACKGROUND: Poor adherence to guidelines aimed at reducing the incidence of postoperative nausea and vomiting (PONV) is well known. In a before-and-after study, we tested the effectiveness of a simplified algorithm for PONV prophylaxis on the incidence of PONV. METHODS: In the first audit, we examined the adherence to our institutional guidelines for PONV prevention. In response to the results of this audit, we introduced a simplified algorithm for PONV prevention [female patients receiving triple prophylaxis (dexamethasone and ondansetron plus either a target-controlled infusion with propofol or droperidol) and male patients receiving double prophylaxis, dexamethasone, and ondansetron]...

INTRODUCTION: Obesity is an important risk factor for depression as more than half of the obese population is susceptible for depression at double rate. Our earlier studies reported the antidepressant potential of 5-HT3 receptor antagonist, ondansetron (OND) in depression associated obesity using behavioral tasks. The present research work is aimed to evaluate the effect of OND on depression associated with obesity with special emphasis on biochemical and molecular mechanisms such as hippocampal brain-derived neurotrophic factor (BDNF), cyclic adenosine monophosphate (cAMP), 5-hydroxytryptamine (5-HT), hippocampal histological examination and immunohistochemical expression of p53 proteins...
