🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is rapidly and almost completely absorbed from the gastrointestinal tract after oral administration. The bioavailability is over 90% and is not significantly affected by food.
DistributionThis medicine distributes widely throughout the body, including into the cerebrospinal fluid, saliva, sputum, and vaginal fluids. It has a low degree of plasma protein binding.
Protein BindingApproximately 11-12% bound to plasma proteins.
MetabolismThis medicine is primarily metabolized in the liver, mainly by cytochrome P450 enzymes, including CYP2C9, CYP2C19, and CYP3A4. It also inhibits CYP2C9, CYP2C19, and CYP3A4, which can lead to drug interactions.
Half-LifeThe elimination half-life is approximately 30 hours in adults with normal renal function. It may be prolonged in patients with renal impairment.
ExcretionAbout 80% of the administered dose is excreted unchanged in the urine, with approximately 11% excreted as metabolites. Renal clearance is proportional to creatinine clearance.
BioavailabilityGreater than 90% after oral administration.
Onset of ActionAntifungal effects begin within a few hours, but clinical improvement may take several days to weeks depending on the infection.
Peak Plasma Time1 to 2 hours after oral administration in fasting state.
Duration of ActionThe antifungal effect persists for at least 24 hours after a single dose due to the long half-life.

How It Works

This medicine works by inhibiting the fungal cytochrome P450 enzyme lanosterol 14-alpha-demethylase, which is responsible for converting lanosterol to ergosterol. Ergosterol is a critical component of the fungal cell membrane. When this enzyme is blocked, the fungal cell membrane becomes defective, leading to increased permeability and leakage of cellular contents. This ultimately results in fungal cell death. This medicine is selective for fungal enzymes over human enzymes, which reduces its toxicity to human cells.

Mechanism Steps

1
Binding to fungal CYP51: This medicine binds to the heme iron of lanosterol 14-alpha-demethylase, blocking the active site.
2
Inhibition of ergosterol synthesis: This prevents the conversion of lanosterol to ergosterol, a key component of the fungal cell membrane.
3
Membrane disruption: The lack of ergosterol and accumulation of abnormal sterols weaken the fungal cell membrane.
4
Fungal cell death: The compromised membrane leads to leakage of cellular contents and ultimately fungal cell death.

1Take this medicine by mouth with a full glass of water.
2You can take it with or without food.

Dosage Information

Adult DosageThe dose of this medicine depends on the type and severity of the fungal infection. For cryptococcal meningitis, the usual dose is 400 mg on the first day, followed by 200 mg to 400 mg once daily. For invasive candidiasis, 400 mg on the first day, then 200 mg to 400 mg daily. For vaginal candidiasis, a single 150 mg dose is typical, but for recurrent or complicated cases, 150 mg every 72 hours for three doses may be used. For prophylaxis in immunocompromised patients, 400 mg once daily. 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 for appropriate dosing in children.
Elderly DosageElderly patients may have reduced renal function, so dose adjustment based on creatinine clearance is recommended. No specific dose adjustments are required beyond renal function monitoring.
Renal ImpairmentIn patients with renal impairment, dose adjustment is required. For patients with creatinine clearance less than 50 mL/min, the dose should be reduced by 50%. For those on hemodialysis, a full dose should be given after each dialysis session.
Hepatic ImpairmentNo specific dose adjustment is provided for hepatic impairment, but this medicine should be used with caution in patients with liver disease. Monitor liver function closely.
Maximum Daily DoseThe maximum recommended daily dose is 400 mg for most indications, but higher doses (up to 800 mg) may be used in certain serious infections under specialist supervision.
