🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is well absorbed from the gastrointestinal tract when taken on an empty stomach. Food can reduce its absorption, so it is recommended to take it at least 1 hour before or 2 hours after a meal.
DistributionThis medicine is widely distributed throughout the body, including into the cerebrospinal fluid, especially when the meninges are inflamed. It also penetrates into macrophages and other cells, which is important for treating intracellular infections.
Protein BindingThis medicine is approximately 80% bound to plasma proteins, primarily albumin.
MetabolismThis medicine is metabolized in the liver, mainly by the cytochrome P450 enzyme system, particularly CYP3A4 and CYP2C9. It undergoes enterohepatic circulation.
Half-LifeThe elimination half-life of this medicine is approximately 3 to 4 hours in healthy individuals, but it may be prolonged in patients with liver disease.
ExcretionThis medicine and its metabolites are excreted primarily in the bile and feces, with a small amount excreted in the urine. It can cause reddish-orange discoloration of body fluids.
BioavailabilityThe oral bioavailability of this medicine is approximately 90% to 95% when taken on an empty stomach.
Onset of ActionThe onset of action is not clearly defined, but therapeutic effects begin within hours to days after starting treatment.
Peak Plasma TimePeak plasma concentrations are reached approximately 2 to 4 hours after oral administration.
Duration of ActionThe duration of action is not well established, but the medicine is usually taken once daily to maintain therapeutic levels.

How It Works

This medicine works by inhibiting the bacterial DNA-dependent RNA polymerase, an enzyme essential for synthesizing RNA from DNA. By binding to the beta subunit of this enzyme, it blocks the elongation of RNA chains, thereby preventing protein synthesis and stopping bacterial growth. This medicine is bactericidal against Mycobacterium tuberculosis and many other bacteria.

Mechanism Steps

1
Entry into bacteria: This medicine penetrates the bacterial cell wall and enters the cytoplasm.
2
Binding to RNA polymerase: It binds specifically to the beta subunit of DNA-dependent RNA polymerase.
3
Inhibition of RNA synthesis: This binding blocks the elongation of RNA chains, preventing the synthesis of essential proteins.
4
Bacterial death: Without RNA and protein synthesis, the bacteria cannot grow or multiply, leading to their death.
