Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Cipro-susceptible | Patients with ciprofloxacin-susceptible bacteria on their rectal swab cultures will receive ciprofloxacin, the standard of care, as prophylaxis for their prostate biopsy~Ciprofloxacin: 500 mg orally 2 hours before prostate biopsy | 0 | 430 | EG000 |
| Group 2 | Cipro-resistant | Patients with ciprofloxacin-resistant bacteria on their rectal swab will receive one of the following drugs:~* trimethoprim-sulfamethoxazole 1 double strength tablet orally 2 hours before the procedure and again 12 hours later~* cefuroxime 500 mg orally 2 hours before the procedure then again 12 hours later~* ceftriaxone 500 mg intramuscularly 2 hours before the procedure~* gentamicin 2mg/kg intramuscularly 2 hours before the procedure~* amikacin 5 mg/kg intramuscularly 2 hours before the procedure~* aztreonam 500 mg intramuscularly 2 hours before the procedure~* imipenem 500 mg intramuscularly 2 hours before the procedure~* ceftriaxone 2000 mg intravenously 1 hour before the procedure~* gentamicin 2 mg/kg intravenously 1 hour before the procedure~* amikacin 5mg/kg intravenously 1 hour before the procedure~* aztreonam 2000 mg intravenously 1 hour before the procedure~* imipenem 1000 mg intravenously 1 hour before the procedure | 0 | 80 | EG001 |
