Paroxysmal extreme pain disorder is an autosomal dominant disorder caused by mutation of the SCN9A gene. In most cases, the pain is relieved by carbamazepine. We report on a novel SCN9A mutation associated with carbamazepine-resistant. The proband was a 7-month-old child who suffered from typical attacks from birth onwards. Sequencing of SCN9A revealed a heterozygous c.4880T>G substitution. Ide...

The activity of cytochrome p450 isozyme 3A4 (CYP3A4) enzyme and P-glycoprotein (P-gp) is modulated by grapefruit juice and herbal drugs. CYP3A4 is the major phase I drug metabolizing enzyme and P-gp is an ATP-dependent drug efflux pump that regulates the intestinal absorption of orally administered drugs. Honey is commonly consumed as a dietary supplement. However, its influence on human CY...

A carbamazepine intoxication with suicide attempt is a relatively common clinical problem that presenting with coma, respiratory depression, arrhythmia, hemodynamic instability and even death. We report a case of severe carbamazepine poisoning that was successfully treated with one session charcoal hemoperfusion. On admission, the patient was comatose and required ventilator support. Hemoperfus...

Carbamazepine is a molecule used to treat specific pathologies; however, it has become an emerging contaminant that dangerous the environment. In marine species and humans, causes cytotoxicity, genotoxicity, reproductive disorders, infertility. Thus, this pollutant been subjected conventional wastewater treatment, achieving low purification. Ecuador, only some studies are related contaminants, ...

The single and combined effects of carbamazepine and vinpocetine on the release of the excitatory amino acid neurotransmitter glutamate, on the rise in internal Na+ (Na(i), as determined with SBFI), and on the rise in internal Ca2+ (Ca(i), as determined with fura-2) induced by an increased permeability of presynaptic Na+ channels, with veratridine, or by an increased permeability of presynaptic...

Carbamazepine is a widely used anticonvulsive agent. Its metabolic pathway leads not only to the major active metabolite, carbamazepine-10,11-epoxide, but also to minor terminal metabolites such as iminostilbene and acridine. Carbamazepine is usually well-tolerated, but it may lead to rare, but serious, hypersensitive reactions associated with hypereosinophilia. The mechanisms of hypersensitivi...

Pharmaceutical residues are of environmental concern since they found in several compartments, including surface, ground and waste waters. However, the effect pharmaceuticals on ecosystems is still under investigation. To date, removal these micropollutants by conventional treatment plants generally ineffective, addition to producing a considerable carbon footprint. In this sense, achieve curre...

Saliva carbamazepine and phenytoin samples were used to monitor treatment in 35 children aged between 2 and 14 years during a 2-year period. All phenytoin levels and over half the carbamazepine levels that were above the therapeutic range were associated with adverse effects. Dose and carbamazepine saliva levels were significantly related but no such relationship was found for phenytoin. There ...
