OBJECTIVE To evaluate the pharmacokinetics of eslicarbazepine acetate (ESL) at steady-state in adults with partial-onset seizures who have taken ESL for at least 1 year with one or two concomitant antiepileptic drugs (AEDs). METHODS Blood samples for the pharmacokinetic assessment were taken at pre-dose, and 1, 2, 3, 4, 6, 8, 12 and 24h post-dose at(More)
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)
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)
The aims of the present research were to characterize the plasma and brain concentration-time profiles of lamotrigine after its acute administration and to establish the relationship between these profiles and the anticonvulsant effect of lamotrigine in rats. Adult male Wistar rats were given 10 mg/kg of lamotrigine intraperitoneally. The lamotrigine(More)
The use and popularity of herbal medicines has been increasing worldwide. In fact, today, the traditional Chinese medicine offers a vast repertory for pharmaceutical research, as is the case of Huperzia serrata, a member of Huperziaceae family. This review reports the Lycopodium alkaloids that have been isolated from this plant. However, it was mainly(More)
The aim of this review is to assess the extent of the use of off-label and/or unlicenced drugs among hospitalised children. A systematic search was made in MEDLINE-PubMED for papers published from 1994 to 2012, addressing the prescription of off-label and/or unlicenced drugs for the paediatric population in hospital care. Of the 829 studies retrieved, 34(More)
Multidrug resistance (MDR) represents one of the major problems in pharmacotherapy of important diseases (e.g., cancer, epilepsy). Although many factors may contribute to the development of MDR phenotype, the increased expression and/or functional activity of P-glycoprotein (P-gp; active drug efflux transporter) across the cell membrane has been recognized(More)
OBJECTIVE Anti-epileptic drugs are often used in combination. Both eslicarbazepine (main metabolite of eslicarbazepine acetate, ESL) and lamotrigine undergo conjugation with glucuronic acid, and both eslicarbazepine and its glucuronide and lamotrigine glucuronide undergo extensive renal elimination; therefore, there is a potential for interaction. This(More)
BACKGROUND Activation of the sympathetic nervous system is an important feature in hypertension and congestive heart failure. A strategy for directly modulating sympathetic nerve function is to reduce the biosynthesis of norepinephrine (noradrenaline) via inhibition of dopamine-β-hydroxylase (DβH). OBJECTIVE To assess the safety, tolerability, and(More)
Paullinia cupana is used in weight-loss programs as a constituent of medicinal/dietary supplements. This study aimed to assess a potential herb-drug interaction among a standardized (certified) Paullinia cupana extract and amiodarone (narrow therapeutic index drug) in rats. In a first pharmacokinetic study rats were simultaneously coadministered with a(More)
