WATCH group - carries resistance cost. Egyptian EML 2025.
Egyptian National Drug Formulary - Antimicrobial 2023 (ceftriaxone monograph, p255) - general adult dosage 1 to 2 g intravenously or intramuscularly once daily or divided twice daily, maximum 4 g daily, with community-acquired intra-abdominal infection among the named indications.
The cholecystitis article's initial management is intravenous fluid resuscitation and prompt broad-spectrum antibiotics effective against gram-negative rods and anaerobes, followed by early laparoscopic cholecystectomy during the same admission because early surgery lowers morbidity and mortality against delayed surgery. Ceftriaxone is the formulary's agent for the gram-negative half. Eight 1 g products are marketed in Egypt.
- GIVEN WITH METRONIDAZOLE, NOT ALONE - the article asks for cover against gram-negative rods AND anaerobes.
- The admission comes first and this is not started in a clinic. It is here so that the referral is an informed one and so a GP recognises the regimen the patient comes back on.
- Right upper quadrant pain that does not settle, with fever and systemic upset and a positive Murphy's sign, is not prolonged biliary colic. Colic settles; cholecystitis does not.
- Contraindicated in penicillin or cephalosporin hypersensitivity, and in the neonate receiving calcium-containing intravenous fluids.
- Where renal and hepatic impairment coexist, the formulary caps the daily dose at 2 g.
- Jaundice, rigors or a septic-looking patient suggests cholangitis or a stone in the common bile duct rather than simple cholecystitis, and changes the urgency.
