Evaluation of amoxicillin therapy in ill children
Insights
Amoxicillin shows better oral absorption than ampicillin in children, with good tolerance and no observed toxicity. Further studies are needed to confirm its clinical advantages in pediatric infectious diseases.
Area of Science:
- Pediatric Infectious Diseases
- Pharmacology
- Clinical Pharmacy
Background:
- Ampicillin and amoxicillin are commonly prescribed antibiotics for pediatric infections.
- Understanding their comparative pharmacokinetic profiles and clinical outcomes is crucial for optimizing treatment.
Purpose of the Study:
- To compare the oral absorption, tolerance, and toxicity of amoxicillin versus ampicillin in ill children.
- To evaluate the suitability of amoxicillin for treating pediatric infectious diseases.
Main Methods:
- Pharmacokinetic studies were conducted in 27 of 37 ill children.
- Oral absorption, tolerance, and toxicity (hematologic, hepatic, renal) were assessed.
- Dosages of 12.5 and 25 mg/kg per dose were used for both antibiotics.
Main Results:
- Amoxicillin demonstrated superior oral absorption compared to ampicillin at both tested dosages.
- Significant individual variation in drug absorption was observed for both antibiotics.
- Amoxicillin was well-tolerated, with no discontinuations due to side effects or observed toxicities in the studied patients.
Conclusions:
- Pharmacokinetic data, clinical efficacy, tolerance, and toxicity profiles support the use of amoxicillin in pediatric infectious diseases.
- Further comparative, controlled clinical investigations are recommended to fully define amoxicillin's advantages over ampicillin.
Abstract:
Ampicillin and amoxicillin were evaluated in 37 ill children. Detailed pharmacokinetic studies in 27 of these children demonstrated an advantage in oral absorption of amoxicillin over ampicillin at dosages of both 12.5 and 25 mg/kg per dose. Individual variation was great for both drugs. No sequence effect was noted for patients receiving ampicillin before either ampicillin or amoxicillin. Amoxicillin was tolerated well by the majority of patients, and the drug was not discontinued because of side effects in any patient. No toxicities were noted for amoxicillin in any of the 20 patients studied for abnormalities in hematologic hepatic, and renal functions. Pharmacokinetics, clinical efficacy, tolerance, and toxicity studies support the clinical usage of amoxicillin in pediatric infectious diseases. However, comparative, controlled clinicalinvestigations are needed to better define the clinical advantages of this drug over ampicillin.
