🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is administered parenterally and is completely absorbed after intramuscular injection. The bioavailability is approximately 100% for intravenous administration and close to 100% for intramuscular administration.
DistributionThis medicine distributes widely into body tissues and fluids, including the cerebrospinal fluid, especially when the meninges are inflamed. It achieves high concentrations in the bile, lungs, and kidneys. It crosses the placenta and is excreted in breast milk in low concentrations.
Protein BindingThis medicine is highly bound to plasma proteins, primarily albumin, with a binding range of 85-95%. The binding is reversible and decreases with increasing concentrations.
MetabolismThis medicine is not significantly metabolized in the body. It is primarily excreted unchanged.
Half-LifeThe elimination half-life of this medicine is approximately 6 to 9 hours in healthy adults. It is prolonged in patients with renal or hepatic impairment.
ExcretionThis medicine is excreted primarily unchanged in the urine (about 33-67%) and in the bile (about 33-67%). In patients with renal impairment, biliary excretion increases. It is also removed by hemodialysis.
BioavailabilityThe bioavailability of this medicine is approximately 100% when administered intravenously and close to 100% when administered intramuscularly.
Onset of ActionThe onset of action is rapid, typically within 1 to 2 hours after administration, as it reaches peak plasma concentrations quickly.
Peak Plasma TimePeak plasma concentrations are achieved within 1 to 2 hours after intramuscular administration and immediately after intravenous administration.
Duration of ActionThe duration of action is typically 12 to 24 hours, depending on the dose and the susceptibility of the infecting organism. This allows for once or twice daily dosing.

How It Works

This medicine works by inhibiting the synthesis of the bacterial cell wall. It binds to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, which are enzymes involved in the cross-linking of peptidoglycan. This inhibition prevents the formation of a functional cell wall, leading to bacterial cell lysis and death. Ceftriaxone is bactericidal and is active against a wide range of gram-positive and gram-negative bacteria.

Mechanism Steps

1
Binding to penicillin-binding proteins: This medicine binds to specific penicillin-binding proteins (PBPs) on the inner membrane of the bacterial cell wall.
2
Inhibition of cell wall synthesis: By binding to PBPs, it inhibits the transpeptidation step in peptidoglycan synthesis, which is essential for cell wall cross-linking.
3
Bacterial cell lysis: The weakened cell wall leads to osmotic instability and ultimately bacterial cell lysis and death.

For uncomplicated gonorrhea, a single 500 mg intramuscular dose is recommended. For serious infections like meningitis, higher doses may be used. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may have reduced renal function, which can affect the elimination of this medicine. Dose adjustment may be necessary based on renal function. Monitor closely for side effects.
Renal ImpairmentIn patients with renal impairment, dose adjustment is usually not required for ceftriaxone unless the impairment is severe (creatinine clearance <10 mL/min). In such cases, the dose should not exceed 2 grams per day. Monitor renal function closely.
Hepatic ImpairmentIn patients with hepatic impairment, dose adjustment is usually not required. However, in patients with both renal and hepatic impairment, monitor plasma concentrations and adjust dose as needed.
Maximum Daily DoseThe maximum daily dose of this medicine is 4 grams, but in severe infections, up to 4 grams per day may be used. Doses above 4 grams per day are not recommended.
