🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is well absorbed from the gastrointestinal tract after oral administration. Food does not significantly affect its absorption, but taking it with food may reduce stomach upset.
DistributionThis medicine distributes widely throughout the body, including into the cerebrospinal fluid, bile, and various tissues. It can cross the placenta and is excreted in breast milk.
Protein BindingLess than 15% of this medicine binds to plasma proteins.
MetabolismThis medicine is metabolized in the liver, primarily by conjugation and oxidation. Some metabolites may have antimicrobial activity.
Half-LifeThe elimination half-life of this medicine is approximately 12 to 14 hours.
ExcretionThis medicine and its metabolites are mainly excreted in the urine, with a small amount eliminated in the feces.
BioavailabilityThe oral bioavailability of this medicine is approximately 90%.
Onset of ActionThe onset of action is typically within 1 to 2 hours after taking a dose, but clinical improvement may take a few days.
Peak Plasma TimePeak plasma concentrations are reached about 2 to 3 hours after oral administration.
Duration of ActionThe antimicrobial effect lasts for about 12 to 24 hours, depending on the dose and the organism.

How It Works

This medicine works by entering microbial cells and interfering with their DNA. Once inside, it is reduced by certain enzymes in anaerobic organisms, creating reactive compounds that break the DNA strands. This damage prevents the microbes from reproducing and causes them to die. Because this process requires low-oxygen conditions, it is highly effective against anaerobic bacteria and parasites but has little effect on human cells.

Mechanism Steps

1
Entry into microbial cell: This medicine passes through the cell membrane of the infectious organism.
2
Reductive activation: Inside the low-oxygen environment of the microbe, the medicine is chemically reduced by specific enzymes.
3
DNA damage: The reduced form creates reactive molecules that bind to and break the microbial DNA.
4
Cell death: The damaged DNA cannot replicate, leading to the death of the infectious organism.
