Insights

Ocular toxicity from Vigabatrin (VGB) can cause visual field defects. Simple ophthalmoscopy in pediatric patients detected surface wrinkling retinopathy and abnormal macular reflexes, indicating VGB

Area of Science:

  • Ophthalmology
  • Neurology
  • Pharmacology

Background:

  • Vigabatrin (VGB) is an antiepileptic drug associated with visual field defects.
  • Assessing visual fields in young children and those with cognitive impairments is challenging.

Purpose of the Study:

  • To investigate ophthalmoscopic abnormalities in pediatric patients undergoing Vigabatrin therapy.
  • To determine if simple ophthalmoscopy can detect ocular toxicity from VGB.

Main Methods:

  • Ophthalmoscopy was performed on seven pediatric patients receiving VGB.
  • Patients had a median VGB treatment duration of 9 months (range, 3-32 months).

Main Results:

  • Two out of seven patients (33.3%) exhibited abnormal ophthalmoscopic findings.
  • Abnormalities included surface wrinkling retinopathy and abnormal macular reflexes.
  • Findings align with previous reports on VGB ocular toxicity.

Conclusions:

  • Simple ophthalmoscopy is effective in identifying ocular toxicity associated with Vigabatrin.
  • Ophthalmological examination aids in managing antiepileptic drug (AED) therapy in patients on VGB.

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

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...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Drug Toxicity: Risk factors

Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

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...
Teratogenicity01:07

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...
