Amikacin Therapy of Urinary tract infections
Abstract:
The efficacy and safety of amikacin in treatment of patients with urinary tract infections were evaluated. Underlying urologic disease was prevalent in the population studied. Amikacin was administered to 50 patients in a dosage of 7.5 mg/kg twice daily. In a subsequent study, amikacin was compared with gentamicin in the treatment of 63 patients; amikacin was administered in a dose of 150 or 200 mg every hr, and gentamicin was administered in doses of 60-80 mg every 8 hr. In the initial study, amikacin produced a bacteriologic cure rate of 86%. In the comparative study, cure rates for gentamicin and amikacin were 85% and 81% respectively. No significant renal toxicity or audiometric changes were attributed to amikacin.
Insights
Amikacin effectively treats urinary tract infections, showing high bacteriologic cure rates in patients, including those with underlying urologic conditions. This antibiotic demonstrated comparable efficacy to gentamicin with no significant safety concerns.
Area of Science:
- Pharmacology
- Infectious Diseases
- Nephrology
Background:
- Urinary tract infections (UTIs) are common, often complicated by underlying urologic diseases.
- Aminoglycosides like amikacin and gentamicin are used for severe UTIs.
Purpose of the Study:
- To evaluate the efficacy and safety of amikacin in treating patients with UTIs.
- To compare amikacin with gentamicin in UTI treatment.
Main Methods:
- Initial study: 50 patients received amikacin (7.5 mg/kg twice daily).
- Comparative study: 63 patients received amikacin (150-200 mg/hr) or gentamicin (60-80 mg every 8 hr).
- Efficacy assessed by bacteriologic cure rates; safety evaluated for renal toxicity and audiometric changes.
Main Results:
- Amikacin achieved an 86% bacteriologic cure rate in the initial study.
- In the comparative study, gentamicin showed an 85% cure rate, and amikacin an 81% cure rate.
- No significant renal toxicity or audiometric changes were observed with amikacin.
Conclusions:
- Amikacin is an effective and safe treatment option for urinary tract infections, even in patients with complex urologic conditions.
- Amikacin demonstrates comparable efficacy to gentamicin in treating UTIs with a favorable safety profile.
