Sex-Related Differences in Pharmacological Response to CNS Drugs: A Narrative Review.

J Pers Med 2022 May 31;12(6). Epub 2022 May 31.

Faculty of Medicine, "Victor Babeş" University of Medicine and Pharmacy, 2 Eftimie Murgu Street, 300041 Timisoara, Romania.

In the last decades, both animal and human studies have neglected female subjects with the aim of evading a theorized intricacy of feminine hormonal status. However, clinical experience proves that pharmacological response may vary between the two sexes since pathophysiological dissimilarities between men and women significantly influence the pharmacokinetics and pharmacodynamics of drugs. Sex-related differences in central nervous system (CNS) medication are particularly challenging to assess due to the complexity of disease manifestation, drugs' intricate mechanisms of action, and lack of trustworthy means of evaluating the clinical response to medication.

Targeted gut microbiota manipulation attenuates seizures in a model of infantile spasms syndrome.

JCI Insight 2022 Jun 22;7(12). Epub 2022 Jun 22.

Department of Biochemistry and Molecular Biology, Cumming School of Medicine, University of Calgary, Calgary, Alberta, Canada.

Infantile spasms syndrome (IS) is a devastating early-onset epileptic encephalopathy associated with poor neurodevelopmental outcomes. When first-line treatment options, including adrenocorticotropic hormone and vigabatrin, are ineffective, the ketogenic diet (KD) is often employed to control seizures. Since the therapeutic impact of the KD is influenced by the gut microbiota, we examined whether targeted microbiota manipulation, mimicking changes induced by the KD, would be valuable in mitigating seizures.

Digoxin at sub-cardiotonic dose modulates the anticonvulsive potential of valproate, levetiracetam and topiramate in experimental primary generalized seizures.

Ceska Slov Farm 2022 ;71(2):78-88

The prevalence of epilepsy in the world population together with a high percentage of patients resistant to existing antiepileptic drugs (AEDs) stimulates the constant search for new approaches to the treatment of the disease. Previously a significant anticonvulsant potential of cardiac glycoside digoxin has been verified by enhancing a weak activity of AEDs in low doses under screening models of seizures induced by pentylenetetrazole and maximal electroshock. The aim of the present study is to investigate the influence of digoxin at a sub-cardiotonic dose on the anticonvulsant activity of valproate, levetiracetam, and topiramate in models of primary generalized seizures with different neurochemical mechanisms.
