Meta-analysis of parenteral clindamycin dosing regimens

Meta-analysis of parenteral clindamycin dosing regimens

Annals of PharmacoTherapy 29(9): 852-858

OBJECTIVE: We used meta-analysis to compare clinical cure and success rates for parenteral clindamycin 600 mg q8h or 900 mg q8h therapy to treat adult intraabdominal or female pelvic infections. DATA SOURCES: We located English-language articles describing clindamycin use in humans using MEDLINE, International Pharmaceutical Abstracts, and Embase and from personal and drug information center files, plus all article references. STUDY SELECTION: Eligible studies used parenteral clindamycin 600 mg q8h or 900 mg q8h to treat intraabdominal or pelvic infection in at least 1 aim of a study and provided a definition of clinical outcome. Accepted were comparative trials in adults who were not critically ill or expected to die. DATA SYNTHESIS: The DerSimonian and Laird method was used to calculate weighted overall success rates for cure and success (cure plus improved) rates along with 95% confidence intervals for each dosage in intraabdominal and pelvic infections. Regimens were compared with respect, to both cure and success rates using the Mann-Whitney U test. MAIN RESULTS: Twenty-three articles were eligible for inclusion. Abdominal cure rates were 75.6% and 90.5% for clindamycin 600 mg q8h and 900 mg q8h, respectively (p = 0.03); success rates were 89.8% and 92.5%, respectively (p = 0.29). Pelvic cure rates were 82.8% and 89.4%, respectively (p = 0.51); success rates were 87.2% and 89.9%, respectively (p = 0.51). CONCLUSIONS: In pelvic infections, a dosage of clindamycin 600 mg q8h appears to be clinically acceptable for all patients. Although clinical outcomes for intraabdominal infections are generally similar for both regimens, the significantly higher cure rate with a dosage of clindamycin 900 mg q8h suggests that dosage recommendations should be patient specific.
