    It was established that the replacement of drinking water by 1.8% NaCl solution in female rats during pregnancy causes experimental pre-eclampsia (EP), as evidenced by an increase in the blood pressure, proteinuria, and edema in the control group as compared to pregnant female rats with normal drinking regime. Animals with EP exhibited disturbance of vasodilating endothelial function, microcirculation disorder, and increased coagulation and thrombogenic potential of blood. In addition, the group with EP showed evidence of the activation of lipid peroxidation (LPO) due to lower activity of antioxidant enzymes. Daily oral administration ofphenibut (25 mg/kg) in female rats with EP during pregnancy prevents the increase in blood pressure and the severity of proteinuria and edemation. Phenibut improves the vasodilator and antithrombotic endothelial functions, increases uterine blood flow, improves microcirculation, limits LPO, and increases the activity of antioxidant enzymes.

    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...

    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: 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...
