What is ceftriaxone?
Ceftriaxone is a broad spectrum antibiotic from the group of cephalosporins (3rd generation). It is used to treat various bacterial infections, including gonorrhea (tripper).
In Gonorrhoe, Ceftriaxon is the means of choice, as many gonococci strains have become resistant to other antibiotics. The treatment is carried out as a single injection, often in combination with oral aziithromycin.
Ceftriaxon must be administered by medical professionals.
Active Ingredients & Mechanism of Action
Active ingredient: Ceftriaxon
Ceftriaxone acts bactericidal by inhibiting cell wall synthesis:
Active mechanism:
- Ties to penicillin-binding proteins (PBPs) of the bacteria
- inhibits cross-linking of the peptideoglykan
- The bacterial cell wall becomes unstable
- The bacteria burst and die
Advantages of Gonorrhoe:
- Very high effectiveness against gonococci
- One-off treatment sufficient
- High tissue concentrations
- Low resistance rates
Pharmacokinetics:
- Long half-life (approx. 8 hours)
- Good penetration into all tissues
- partial renal, partly biliary excretion
Who is it suitable for?
Ceftriaxone is suitable for:
- Uncomplicated Gonorrhoe (genital, pharyngeal, rectal)
- Gonorrhoea in pregnancy
- Disseminated gonococci infection
- Other serious bacterial infections
Standard treatment Gonorrhoe: Ceftriaxone 1 g i.m. (intramuscular) unique PLUS Azithromycin 2 g oral unique
Not suitable for:

After treatment:
- Sexual abstinence for 7 days
- All sexual partners of the last 60 days inform and treat
- Test for more STI recommended (HIV, Syphilis, Chlamydien)
