RESUMO: "Uma revisão de plantas com propriedades anticonvulsivantes". Cerca de um terço dos pacientes epilépticos não conseguem ter um tratamento adequado com as drogas anticonvulsivantes atuais. Nesse sentido, as plantas medicinais surgem como uma fonte promissora de novas moléculas químicas com propriedades biológicas apreciáveis. Muitas plantas ou produtos de origem naturais têm sido propostos para o tratamento de várias patologias, tais como: epilepsia, diabetes, ansiedade, depressão, dentre outras. O presente trabalho realizou um extenso levantamento na literatura especializada de plantas medicinais com propriedades anticonvulsivantes. Um total de 355 espécies vegetais foi identifi cado, sendo 16 plantas encontradas na fl ora brasileira, com indicação para o tratamento de quadros convulsivos. Características como nome da espécie, família, partes utilizadas, país do estudo e /ou publicação, métodos e referências foram sumarizados. Além disso, os principais apectos dos modelos animais mais utilizados no estudo de plantas/substâncias com propriedades anticonvulsivantes foram revisados. Mais de 170 referências foram consultadas.Unitermos: Plantas medicinais, Produtos naturais, convulsão, atividade anticonvulsivante, modelos animais, revisão. ABSTRACT:Seizures are resistant to treatment with currently available anticonvulsant drugs in about 1 out of 3 patients with epilepsy. Thus, there is a need for new, more effective anticonvulsant drugs for intractable epilepsy. However, nature is a rich source of biological and chemical diversity and a number of plants in the world have been used in traditional medicine remedies, i.e., anticonvulsant, anxiolytic, analgesic, antidepressant. This work constitutes a literature review on medicinal plants showing anticonvulsant properties. The review refers to 16 Brazilian plants and a total 355 species, their families, geographical distribution, the utilized parts, method and references. Some aspects of research on medicinal plants and a brief review of the most common animal models to discover antiepileptic drugs are discussed. For this purpose over 170 references were consulted.

Dental prescribing errors should be considered as a potential area for improvement in the medication management process and patient safety. We suggest that a pharmacist should be available for medication dispensing at all units and that dentists are trained continuously so that medication orders may become more legible and complete. Improving the quality of dental prescriptions will reduce the risks for medication errors and will promote the rational use of pharmacotherapy, and patient safety.

Citral (CIT), which contains the chiral enantiomers, neral (cis) and geranial (trans), is the majority monoterpene from Lippia alba and Cymbopogon citratus. The present study aimed to evaluate CIT for antinociceptive and antiinflammatory activities in rodents. Antinociceptive and anti-inflammatory effects were studied by measuring nociception through acetic acid and formalin tests, while inflammation was verified by inducing peritonitis and paw edema with carrageenan. All tested doses of CIT had significant protection (p<0.001) against acetic acid (0.8%) induced nociceptive behavior and the effects were also similar to morphine while formalin induced nociception was significantly protected (p<0.05) only at higher dose (200 mg/kg) of CIT in the first phase of the test. CIT significantly reduce (p<0.001) nociceptive behavior emanating from inflammation in second phase at all the doses.The pretreatment with CIT (100 and 200 mg/kg) significantly reduced the paw edema induced by carrageenan. Moreover, systemic treatment with CIT (100 and 200 mg/kg) significantly reduced (p<0.001) the leukocyte migration in the carrageenaninduced migration to the peritoneal cavity. Our investigation shows that CIT possess significant central and peripheral antinociceptive effects. It was also verified an anti-inflammatory activity. All together these results suggest that CIT might represent important tool for treatment of painful conditions.

ABSTRACT:The ethanolic extract of the trunk bark of Amburana cearensis (EEA) was examined for its oral (p.o.) analgesic activity at the doses of 100, 200 and 400 mg/kg body weight. In the acetic acid-induced writhing test, the EEA (200 and 400 mg/kg, p.o.) reduced the number of writhing by 33.4% and 40.7%, respectively. Additionally, EEA (100, 200 and 400 mg/kg, p.o.) decreased by 77.5%, 79.7 and 91.3%, respectively, the paw liking time in the second phase of the formalin test. Therefore, EEA showed a dose-dependent analgesic effect in formalin test and was effective in reducing writhing in mice.
