Insights
Global anti-epileptic drug (AED) use shows variation, with a growing trend towards newer medications like levetiracetam. Older drugs remain common, highlighting the need for current pediatric data.
Area of Science:
- Pharmacology
- Neurology
- Global Health
Background:
- Anti-epileptic drugs (AEDs) are crucial for managing epilepsy.
- Understanding global AED utilization patterns is essential for public health initiatives.
- Paediatric epilepsy management requires specific consideration of drug safety and efficacy.
Purpose of the Study:
- To determine the global prevalence of anti-epileptic drug (AED) utilization.
- To describe trends in AED utilization across different countries.
- To analyze the use of older versus newer generation AEDs in paediatric populations.
Main Methods:
- Systematic literature search of Embase, Medline, and PubMed databases (up to May 2017).
- Inclusion of original research on AED utilization, focusing on paediatric national or regional database studies and surveys.
- Analysis of 16 relevant studies with data collected from 2005 onwards.
Main Results:
- Monotherapy regimens ranged from 58% to 94% across different countries.
- Sodium valproate was frequently prescribed in several studies.
- A trend towards increased utilization of newer AEDs, such as levetiracetam, was observed in some regions.
Conclusions:
- Monotherapy is widely used, accounting for 58%-94% of patient cases.
- Newer generation AEDs, including lamotrigine, levetiracetam, and topiramate, show increasing utilization.
- Despite the rise of new AEDs, older generation drugs remain prevalent, necessitating updated studies on paediatric AED use.
Objectives:
This study aims to determine global anti-epileptic drug (AED) utilisation prevalence and describe utilisation trends in different countries.
Methods:
Databases Embase (1980-May 2017), Medline (1946-May 2017) and PubMed were searched for original research on AED utilisation. All paediatric national or regional database studies and surveys were included.
Results:
Twenty-one studies were identified. Five were excluded from the analysis as the data were collected before 2005, leaving 16 studies. Monotherapy regimen varied between 58% and 94% in different countries. In several of the studies, sodium valproate was the most frequently prescribed AED. However, there is a trend towards increasing utilisation of new-generation AEDs, particularly levetiracetam, in some countries.
Conclusion:
Monotherapy was used in 58%-94%of patients. There is increasing utilisation of the new-generation AEDs, in particular lamotrigine, levetiracetam and topiramate. Old-generation AEDs are still used in the majority of patients. There is a need for up-to-date studies to determine the prevalence of AEDs in children.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
