Two to three days treatment of typhoid fever with ceftriaxone.

Pharmacokinetic properties of ceftriaxone, such as sustained tissue drug levels over 24 hours after a single injection; good penetration of the antibiotic into cells; significant biliary excretion as active unchanged compound and high potency against S. typhi, should make it possible to significantly shorten the treatment of typhoid fever. To test this hypothesis a pilot, open study was initiated. 17 adult patients suffering from uncomplicated typhoid or paratyphoid fever, documented by blood culture, were treated with 4g ceftriaxone once daily for three days (4 patients) or two days (15 patients). The cure rate of 17 assessable patients was 94.2% (one failure). One possible relapse was observed two months after treatment. It is to be noted that no patient in the study suffered from a severe form of the disease.
