[Pharmacokinetic and clinical evaluation of azithromycin in pediatrics]
Insights
Azithromycin (AZM) is a potent macrolide antibiotic effective against common pediatric bacterial infections. Clinical studies show AZM is well-tolerated and achieves favorable pharmacokinetic profiles in children.
Area of Science:
- Pharmacology
- Pediatric Infectious Diseases
- Microbiology
Background:
- Azithromycin (AZM) is a novel macrolide antibiotic.
- Bacterial infections remain a significant concern in pediatric populations.
Purpose of the Study:
- To evaluate the pharmacokinetic and clinical efficacy of Azithromycin in pediatric patients.
- To assess the antimicrobial activity of Azithromycin against clinically isolated bacteria.
Main Methods:
- Pediatric patients received Azithromycin at 10 mg/kg once daily for 3 days.
- Plasma and urine drug levels were determined.
- Clinical effectiveness and bacterial eradication rates were assessed.
Main Results:
- Azithromycin demonstrated potent activity against Gram-positive and Gram-negative bacteria.
- Therapeutic drug concentrations were observed in plasma and urine.
- Azithromycin was effective in 37 of 38 pediatric cases, with a 56.7% bacterial eradication rate.
- Adverse events were mild, including vomiting and eosinophilia.
Conclusions:
- Azithromycin is an effective and well-tolerated antibiotic for treating bacterial infections in children.
- The pharmacokinetic profile supports its use in pediatric patients.
- Further research may explore broader applications and optimal dosing regimens.
Abstract:
Azithromycin (AZM), a new macrolide antibiotic, in fine granules and in capsules was administered at a standard dose of 10 mg/kg once daily for 3 days to pediatric patients with bacterial infections. AZM was studied for its pharmacokinetic and clinical evaluation. 1. AZM possessed potent activity against Gram-positive bacteria and Gram-negative bacteria that had been clinically isolated. 2. Plasma samples were collected from two patients diagnosed as having pneumonia or enteritis, and urine samples were collected from one patient diagnosed as having pneumonia for drug level determination. The drug concentrations in plasma were 0.095 and 0.204 microgram/ml just before the end of treatment, and 0.017 and 0.096 microgram/ml at 48 hours post-treatment. The drug concentrations in urine were 5.16 micrograms/ml and 5.63 micrograms/ml during a period between 24 and 48 hours and between 48 and 72 hours after the start of treatment, respectively. 3. The drug was found effective in 37 of 38 cases with various pediatric infections. AZM treatment eradicated bacteria in 17 of 30 strains (56.7%). 4. One patient complained of mild vomiting, while abnormal laboratory test results indicating mild eosinophilia were reported in four cases.
