Little information is available on the need for dosage changes for lamotrigine in pregnant women with bipolar disorder. The authors present new data on serial serum levels of lamotrigine in pregnant patients on lamotrigine monotherapy. They also review the epilepsy

Carisbamate and lamotrigine are anticonvulsants that act on neuronal voltage-gated sodium channels. Carisbamate has shown antidepressant-like effects in animal models of depression, and lamotrigine is a mood stabilizer with a therapeutic effect in depressive episodes of patients with bipolar disorder.

Brain drug bioavailability is regulated by the blood-brain barrier (BBB). It was recently suggested that cytochrome P450 (CYP) enzymes could act in concert with multidrug transporter proteins to regulate drug penetration and distribution into the diseased brain. The possibility that

Typical therapies try to reverse pathogenic mechanisms. Here, we describe treatment effects achieved by enhancing depression-causing mechanisms in ventral tegmental area (VTA) dopamine (DA) neurons. In a social defeat stress model of depression, depressed (susceptible) mice display hyperactivity of VTA

Resistance to antiepileptic drugs (AEDs) is the major problem in the treatment of epilepsy. One hypothesis to explain AED resistance suggests that seizure-induced overexpression of efflux transporters at the blood-brain barrier (BBB) restricts AEDs to reach their brain targets. Various
