  • Gabitril® (Tiagabine)
    Gabitril (Tiagabine) What is Gabitril (Tiagabine)? Gabitril is an anti-epileptic drug that has been used to treat patients with epilepsy since 1997. It is helpful in the treatment of partial seizures. Starting the Medicine: We usually gradually increase the dose, until your body gets adjusted to the medication. Since each patient is unique in that he/she breaks down the medication differently or may need a higher or lower dosage to control their seizures, there is no standard dose that is appropriate for all patients. What dosages does the pill come in and what does it look like? 4 mg round, yellow tablet 12 mg oval, green tablet 16 mg oval, blue tablet 20 mg oval, pink tablet What Side Effects Can Be Caused By Gabitril? Side effects can be dose related (common) or idiosyncratic (rare): Common Dose - Related Side Effects: Dizziness, drowsiness, difficulty concentrating, or nausea may occur. If you have these side effects, your doctor may: • spread out the dose more frequently during the day • slow the rate of dose increase Comprehensive Epilepsy Center (734) 936-9020 - 1 - • instruct you to take the pills with food since this will slow the rate at which the medicine gets into the blood, but will not affect the total amount that is absorbed. Rare Side Effects: Rare side effects may include: difficulty sleeping, nervousness, or balance problems. Skin Rash: An allergic reaction, or rash, may occur with Gabitril. If this occurs, notify your doctor immediately. Pregnancy: Currently, no information is available about the effects of Gabitril during pregnancy. Any woman taking Gabitril should discuss this issue with her doctor BEFORE becoming pregnant.

  • Revised Use-Function Classification (2007)
    INTERNATIONAL PROGRAMME ON CHEMICAL SAFETY IPCS INTOX Data Management System (INTOX DMS) Revised Use-Function Classification (2007) The Use-Function Classification is used in two places in the INTOX Data Management System: the Communication Record and the Agent/Product Record. The two records are linked: if there is an agent record for a Centre Agent that is the subject of a call, the appropriate Intended Use-Function can be selected automatically in the Communication Record. The Use-Function Classification is used when generating reports, both standard and customized, and for searching the case and agent databases. In particular, INTOX standard reports use the top level headings of the Intended Use-Functions that were selected for Centre Agents in the Communication Record (e.g. if an agent was classified as an Analgesic for Human Use in the Communication Record, it would be logged as a Pharmaceutical for Human Use in the report). The Use-Function classification is very important for ensuring harmonized data collection. In version 4.4 of the software, 5 new additions were made to the top levels of the classification provided with the system for the classification of organisms (items XIV to XVIII). This is a 'convenience' classification to facilitate searching of the Communications database. A taxonomic classification for organisms is provided within the INTOX DMS Agent Explorer. In May/June 2006 INTOX users were surveyed to find out whether they had made any changes to the Use-Function Classification. These changes were then discussed at the 4th and 5th Meetings of INTOX Users. Version 4.5 of the INTOX DMS includes the revised pesticides classification (shown in full below).

In such cases, the combinations of AEDs usually offer a significant enhancement of their protective effects against seizures. There has appeared a hypothesis that combining two AEDs, influencing the same neurotransmitter system, results in the potentialization of their anticonvulsant effects. For corroborating this hypothesis, a pharmacological character of interaction between tiagabine (TGB) and gabapentin F (GBP) two novel AEDs affecting the GABA-ergic system, in the maximal electroshock seizure threshold (MEST)-test in mice was evaluated. TGB at the dose of 4 mg/kg and GBP at 75 mg/kg significantly raised the electroconvulsive threshold. Further, using the isobolographic calculations, TGB was coadministered with GBP at three fixed-ratios (1 : 3, 1 : 1, and 3 : 1) of their respective protective drug doses. All examined combinations of TGB with GBP exerted supra-additive (synergistic) interactions against MEST-induced seizures in mice. The interaction index, describing the strength and magnitude of interaction, ranged between 0.25 and 0.50 indicating supra- additivity.

  • Against the Plasmodium Falciparum Apicoplast
    A Systematic In Silico Search for Target Similarity Identifies Several Approved Drugs with Potential Activity against the Plasmodium falciparum Apicoplast Nadlla Alves Bispo1, Richard Culleton2, Lourival Almeida Silva1, Pedro Cravo1,3* 1 Instituto de Patologia Tropical e Sau´de Pu´blica/Universidade Federal de Goia´s/Goiaˆnia, Brazil, 2 Malaria Unit/Institute of Tropical Medicine (NEKKEN)/Nagasaki University/ Nagasaki, Japan, 3 Centro de Mala´ria e Doenc¸as Tropicais.LA/IHMT/Universidade Nova de Lisboa/Lisboa, Portugal Abstract Most of the drugs in use against Plasmodium falciparum share similar modes of action and, consequently, there is a need to identify alternative potential drug targets. Here, we focus on the apicoplast, a malarial plastid-like organelle of algal source which evolved through secondary endosymbiosis. We undertake a systematic in silico target-based identification approach for detecting drugs already approved for clinical use in humans that may be able to interfere with the P. falciparum apicoplast. The P. falciparum genome database GeneDB was used to compile a list of <600 proteins containing apicoplast signal peptides. Each of these proteins was treated as a potential drug target and its predicted sequence was used to interrogate three different freely available databases (Therapeutic Target Database, DrugBank and STITCH3.1) that provide synoptic data on drugs and their primary or putative drug targets. We were able to identify several drugs that are expected to interact with forty-seven (47) peptides predicted to be involved in the biology of the P. falciparum apicoplast. Fifteen (15) of these putative targets are predicted to have affinity to drugs that are already approved for clinical use but have never been evaluated against malaria parasites.

  • Shared Care Guideline for Tiagabine (Gabitril®) for Use As Add on Therapy for Partial Seizures in Adults and Children Over 12
    Dorset Medicines Advisory Group SHARED CARE GUIDELINE FOR TIAGABINE (GABITRIL®) FOR USE AS ADD ON THERAPY FOR PARTIAL SEIZURES IN ADULTS AND CHILDREN OVER 12 INDICATION Licensed indications & therapeutic class Tiagabine is an anti-epileptic drug indicated as add-on therapy for partial seizures with or without secondary generalisation where control is not achieved by optimal doses of at least one other anti- epileptic drug. Tiagabine is licensed only for use in adults and children over the age of 12. It is not licensed for monotherapy. NICE CG137: Epilepsies: diagnosis and management (page 26) states: Offer carbamazepine, clobazam, gabapentin, lamotrigine, levetiracetam, oxcarbazepine, sodium valproate or topiramate as adjunctive treatment to children, young people and adults with focal seizures if first-line treatments [carbamazepine or lamotrigine, levetiracetam, oxcarbazepine or sodium valoprate] are ineffective or not tolerated. If adjunctive treatment is ineffective or not tolerated, discuss with, or refer to, a tertiary epilepsy specialist. Other AEDs that may be considered by the tertiary epilepsy specialist are eslicarbazepine acetate, lacosamide, phenobarbital, phenytoin, pregabalin, tiagabine, vigabatrin and zonisamide. Carefully consider the risk–benefit ratio when using vigabatrin because of the risk of an irreversible effect on visual fields. NICE also has a “Do not do” recommendation in relation to tiagabine: “Do not offer carbamazepine, gabapentin, oxcarbazepine, phenytoin, pregabalin, tiagabine or vigabatrin as adjunctive treatment in children, young people and adults with childhood absence epilepsy, juvenile absence epilepsy or other absence epilepsy syndromes.” AREAS OF RESPONSIBILITY FOR SHARED CARE Patients should be at the centre of any shared care arrangements. Individual patient information and a record of their preferences should accompany shared care prescribing guidelines, where appropriate.

This study investigated tiagabine monotherapy in subjects with generalized anxiety disorder (GAD) who had been switched from selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs) as a result of antidepressant-induced sexual dysfunction. Methods. Adults with DSM-IV GAD, an adequate therapeutic response (≥50% decrease in Hamilton Rating Scale for Anxiety [HAM-A] total score) to SSRI or SNRI and sexual dysfunction were switched to open-label tiagabine 4–12 mg/day for 14 weeks. Assessments included the HAM-A, Hospital Anxiety & Depression Scale (HADS) and the Arizona Sexual Experiences Scale (ASEX); assessments were made at baseline and at Weeks 4, 8, and 14. Results. Twenty six subjects were included in the analysis. Tiagabine showed no worsening in baseline symptoms of GAD, with non-significant changes from baseline in mean HAM-A total scores and HADS Anxiety and Depression subscale scores.

Three-dimensional (3D) structure of calcium channel as a receptor for 1,4-dihydropyridine is a step in understanding its mode of action. Protein structure prediction and modeling tools are becoming integral parts of the standard toolkit in biological and biomedical research. So, homology modeling (HM) of calcium channel alpha-1C subunit as DHP receptor model was achieved. The 3D structure of potassium channel was used as template for HM process. The resulted dihydropyridine receptor model was checked by different means to assure stereochemical quality and structural integrity of the model.
