Following first pass hydrolysis of ESL, S-licarbazepine (S-Lic) 14 represents around 95 % of circulating active metabolites. S-Lic is the main enantiomer responsible 15 for anticonvulsant activity and this is proposed to be through the blockade of voltage-gated Na+ 16 channels (VGSCs). ESL and S-Lic both have a voltage-dependent inhibitory effect on the Na+ current 17 in N1E-115 neuroblastoma cells expressing neuronal VGSC subtypes including Nav1.1, Nav1.2, 18 Nav1.3, Nav1.6 and Nav1.7.

It explains how the Committee for Medicinal Products for Human Use (CHMP) assessed the studies performed, to reach their recommendations on how to use the medicine. If you need more information about your medical condition or your treatment, read the Package Leaflet (also part of the EPAR) or contact your doctor or pharmacist. If you want more information on the basis of the CHMP recommendations, read the Scientific Discussion (also part of the EPAR). What is Ranexa? Ranexa is a medicine that contains the active substance ranolazine. It is available as oval prolonged- release tablets (blue: 375 mg; orange: 500 mg; green: 750 mg). ‘Prolonged release’ means that ranolazine is released slowly from the tablet over a few hours. What is Ranexa used for? Ranexa is used to treat the symptoms of stable angina pectoris (chest pain caused by reduced blood flow to the heart). It is used as an add-on to existing treatment in patients whose disease is not adequately controlled by other medicines for angina pectoris, such as beta-blockers or calcium antagonists, or in patients who cannot take these medicines. The medicine can only be obtained with a prescription. How is Ranexa used? The recommended starting dose of Ranexa is 375 mg twice a day. After two to four weeks, the dose should be increased to 500 mg twice a day, and then to 750 mg twice a day, depending on the patient’s response.

  • Anaesthetic Guideline for the Management of Children with Long QT Syndrome SOP/Protocol Detail Owner: Dr
    Anaesthetic Guideline for the management of children with long QT Syndrome SOP/Protocol Detail Owner: Dr. Jutta Scheffczik Publication: December 2020 Review: December 2023 Aims To ensure the safety of paediatric patients with congenital or acquired long QT syndrome who need a general anaesthetic. It is anticipated that most patients will undergo anaesthesia in Leeds and this guideline is to support those patients who do need to have a general anaesthetic at their local hospital. Objectives 1.To provide guidance on the management of children with LQTS 2.To enable children to have minor surgery in their local hospital where appropriate 3.To improve equity and consistency in care across the Yorkshire and Humber CHD Network Background Long QT syndrome is a congenital or acquired channelopathy, impairing myocardial electrical conduction that results in impaired ventricular repolarization and can present clinically as recurrent syncope, pseudo-seizures, or sudden death. Patients with QT prolongation and LQTS are susceptible to the development of the characteristic polymorphic ventricular tachycardia, called Torsades de Pointes TdP. The prolongation of the QT interval caused by anaesthetic drugs and the sympathetic response to anaesthesia and surgery can trigger malignant arrhythmias in patients with long QT syndrome. Patients with a genetic predisposition to LQTS may be asymptomatic and may have a normal resting QTc interval, it is possible for an episode of torsade de pointes to occur for the first time during anaesthesia. Diagnosis The diagnosis of long QT syndrome should be made by a paediatrician, a paediatrician with an expertise in cardiology or a paediatric cardiologist. QT intervals need to be corrected for heart rate (QTc – routinely defined using the Bazzett formula) and are highly variable, but the abnormal corrected values are defined as a pre-puberty average of >470ms in males, >480ms in females.

  • CBD and Potential Drug Interactions
    CBD and Potential Drug Interactions Certain substances such as (CBD, THC, grapefruit, St. John’s Wort, watercress, etc.) can affect drug metabolism, making certain drugs metabolize faster or slower than they would on their own. Cannabidiol (CBD) can temporarily inhibit the one of the most common metabolism pathways (CYP450) ability to metabolize certain drugs leading to an increase (or decrease) in blood levels, unwanted side effects, and sometimes, an overdose. Some pharmaceuticals, called “prodrugs” (tamoxifen,5-FU, Simvastatin, Levodopa, Enalapril) don’t become functional until they are metabolized into an active component. If CBD or THC slow the metabolism of a pro-drug, it can adversely affect final levels of the desired active drug. If you have been hospitalized resulting from CBD use or taking any of the below drugs consult with your doctor prior to registering.

  • Brand Name: Aptiom Generic Name: Eslicarbazepine Manufacturer: Sunovion Pharmaceuticals Inc1 Product Availability: FDA Approved November 2013
    Brand Name: Aptiom Generic Name: eslicarbazepine Manufacturer: Sunovion Pharmaceuticals Inc1 Product Availability: FDA approved November 2013. Anticipated availability is late 2014.2 Drug Class: Anticonvulsant, central nervous system agent, voltage-gated sodium channel blocker 3,4 Uses: Labeled uses: Adjunctive treatment of partial seizures3,4 Unlabeled uses: None o Under investigation for use as monotherapy for treatment of focal epilepsy or partial-onset seizures5 o Under investigation as a possible treatment for bipolar disorder3,5,6 Mechanism of Action: Like many other anticonvulsants, the exact mechanism of action of eslicarbazepine is unknown. The antiepileptic action of the drug is theorized to be due to the blockage of voltage-gated sodium channels. Studies indicate that eslicarbazepine and its metabolites competitively interact with voltage-gated sodium channels to inhibit sustained repetitive neuronal firing, with enhanced inhibitory selectivity for rapidly firing neurons.1,3 Pharmacokinetics: Absorption: 1,3 Tmax 1-4 hours Vd 61 L t ½ 13-20 hours Clearance 20 mL/min GFR 80-120 mL/min Protein binding < 40% (% to albumin unknown) Bioavailability > 90% Metabolism: 1,3 Eslicarbazepine is rapidly metabolized to its major active metabolite eslicarbazepine (91%) by hydrolytic first-pass metabolism. Minor active metabolites are R-licarbazepine (5%) and oxcarbazepine (1%). In in vitro studies, eslicarbazepine acetate was found to be a moderate inhibitor of CYP2C19 and an inducer of CYP3A4. Studies with eslicarbazepine in fresh human hepatocytes showed only mild activation of UGT1A1- mediated glucuronidation. Eslicarbazepine showed no clinical inhibitory effects on CYP1A2, CYP2A6, CYP2B6, CYP2D6, CYP2E1, and CYP3A4 and did not undergo autoinduction. Elimination: 1,3 Eslicarbazepine metabolites are eliminated primarily by renal excretion in the unchanged and glucuronide conjugate forms.
