Summary
Children and adults show similar sensitivity to antimalarials like chloroquine when dosage is considered per kilogram. While fatal reactions are rare, physicians should exercise caution to prevent poisoning, especially with overdosage.
Area of Science:
- Dermatology
- Pharmacology
- Toxicology
Background:
- Antimalarials have been reviewed for dermatological use since 1963.
- A noted special sensitivity in children to antimalarials has been consistently reported.
- Fatal reactions are primarily linked to accidental or intentional overdosage and rare injection instances.
Purpose of the Study:
- To analyze the sensitivity of different age groups to antimalarials.
- To compare the toxicity of antimalarials in children and adults on a mg/kg basis.
- To inform appropriate clinical use of antimalarials in dermatology.
Main Methods:
- Review of published and unpublished case reports.
- Comparative analysis of antimalarial toxicity.
- Dosage-based sensitivity assessment (mg/kg).
Main Results:
- While 1 gm of chloroquine can be fatal in very young children, adults show comparable sensitivity on a mg/kg basis.
- Fatal reactions are predominantly associated with significant overdosage.
- No significant difference in sensitivity was found between age groups when adjusted for body weight.
Conclusions:
- Physicians should consider antimalarials for appropriate dermatological indications.
- Strict adherence to dosage guidelines is crucial to prevent toxic reactions.
- Enhanced precautions are necessary to avoid accidental or intentional poisoning with antimalarials.
