    Pituitary-thyroid axis function and gonadotropin secretion were evaluated by a combined TRH and LHRH test in 4 newborn female infants appropriate for gestational age of mothers treated by AEDs throughout pregnancy. We found: high basal FSH levels with normal FSH reserve, normal LH-HCG levels both before and after LHRH stimulation, normal TSH and T4 levels both before and after TRH stimulation, high T3 basal values with a normal increase after TRH and low rT3 basal values. It is suggested an AED increased T4 deiodination towards T3 in the newborn liver without a marked impairment of the endocrine functions of the fetus.

    Teratogenicity

    The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

    Mania and Antimanic Drugs: Overview

    Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as a...

    Antiepileptic Drugs: GABAergic Pathway Potentiators

    γ-aminobutyric acid or GABA, plays a pivotal role as an inhibitory neurotransmitter in the brain. GABA pathway potentiators, also known as GABAergic drugs, are a class of pharmaceutical agents designed to enhance the functioning of the GABAergic system. These medications primarily treat epilepsy, a neurological disorder characterized by recurrent seizures.
    The key GABA pathway potentiators used in epilepsy management are as follows.
    Benzodiazepines are a well-known class of drugs used for their...

    Antiepileptic Drugs: Glutamate Antagonists

    Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...

    Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

    Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
    SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

    Antiepileptic Drugs: Potassium Channel Activators

    Ezocgabine or retigabine, an antiepileptic drug of remarkable efficacy, has revolutionized the management of seizures. It is a potassium channel activator, explicitly targeting the family of Q subtype potassium channels. It enhances the transmembrane potassium currents, regulating neuronal excitability. This action stabilizes the resting membrane potential, a pivotal factor in mitigating the hyperexcitability that characterizes epilepsy.
    Ezogabine has gained approval as an adjunctive treatment...
