Over the recent decades the interest in intranasal delivery as a non-invasive route for drugs is increased.Since the nasal mucosa offers numerous benefits as a target tissue for drug delivery, a wide variety of therapeutic compounds may be administered intranasally for topic, systemic and central nervous system action. We have, herein, outlined the relevant(More)
This was a double-blind, randomised, placebo-controlled study to investigate the pharmacokinetics and safety of trans-resveratrol. In four groups of ten healthy adult subjects (five males and five females), two subjects were randomized to receive placebo and eight subjects to receive trans-resveratrol 25, 50, 100 or 150 mg, six times/day, for thirteen(More)
The choice of appropriate animal models for the initial in vivo testing of potential anticonvulsant compounds is one of the most important steps in the successful search for new antiepileptic drugs. The purpose of this paper is to describe the most important aspects to take into account when performing the maximal electroshock seizure (MES) test in the(More)
PURPOSE To evaluate the efficacy and safety profile of eslicarbazepine acetate (ESL) added to stable antiepileptic therapy in adults with partial-onset seizures. METHODS Data from 1,049 patients enrolled from 125 centers, in 23 countries, in three phase III double-blind, randomized, placebo-controlled studies were pooled and analyzed. Following a 2-week(More)
Inappropriate prescription has been associated with mounting rates of antibiotic resistance worldwide, demanding more detailed studies into physicians' decision-making process. Accordingly, this study sought to explore physicians' perceptions of factors influencing antibiotic prescribing. A systematic search was performed for qualitative studies focused on(More)
This study investigates the pharmacokinetics of eslicarbazepine acetate (ESL), a new voltage-gated sodium channel blocker, in epileptic children aged 2 to 7 years (n = 11) and 7 to 11 years (n = 8) and adolescents aged 12 to 17 years (n = 10). The study explores ESL efficacy and tolerability. Patients were treated with ESL once-daily doses of 5 mg/kg/day on(More)
When the assumption of homoscedasticity is not met for analytical data, a simple and effective way to counteract the greater influence of the greater concentrations on the fitted regression line is to use weighted least squares linear regression (WLSLR). The purpose of the present paper is to stress the relevance of weighting schemes for linear regression(More)
PURPOSE To evaluate the pharmacokinetics and tolerability of once-daily eslicarbazepine acetate (ESL) and twice-daily oxcarbazepine (OXC) and their metabolites in cerebrospinal fluid (CSF) and plasma following repeated oral administration. METHODS Single-center, open-label, randomized, parallel-group study in healthy volunteers. Volunteers in ESL group (n(More)
OBJECTIVE To evaluate the long-term safety, tolerability and efficacy of once-daily eslicarbazepine acetate (ESL) as adjunctive therapy in adults with partial-onset seizures. METHODS One-year open-label extension (OLE) study with ESL in patients who completed a randomised, double-blind placebo-controlled trial (study BIA-2093-302; Epilepsy Res. 89 (2010)(More)
