🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is rapidly and almost completely absorbed from the gastrointestinal tract after oral administration. Food does not significantly affect its absorption. The bioavailability is high, approximately 90%.
DistributionThis medicine distributes widely throughout the body, including into the cerebrospinal fluid, saliva, sputum, and vaginal secretions. It has a low degree of plasma protein binding, approximately 11-12%.
Protein BindingApproximately 11-12% bound to plasma proteins.
MetabolismThis medicine is primarily metabolized in the liver, but a significant portion (about 80%) is excreted unchanged in the urine. It is a potent inhibitor of CYP2C9 and CYP3A4 enzymes, which can lead to drug interactions.
Half-LifeThe elimination half-life of this medicine is approximately 30 hours in adults with normal renal function. It may be prolonged in patients with renal impairment.
ExcretionAbout 80% of this medicine is excreted unchanged in the urine, with the remainder excreted as metabolites. Renal clearance is proportional to creatinine clearance.
BioavailabilityApproximately 90% after oral administration.
Onset of ActionThe onset of action varies depending on the infection. For vaginal candidiasis, symptom relief may begin within 24 hours, but full effect may take several days.
Peak Plasma TimePeak plasma concentrations are reached 1 to 2 hours after oral administration.
Duration of ActionThe duration of action depends on the indication and dosing regimen. With a half-life of about 30 hours, steady-state levels are achieved after 5-7 days of daily dosing.

How It Works

This medicine works by inhibiting the fungal cytochrome P450 enzyme 14-alpha-demethylase, which is responsible for converting lanosterol to ergosterol. Ergosterol is a vital component of the fungal cell membrane. By blocking this step, the medicine disrupts the synthesis of ergosterol, leading to a weakened and permeable cell membrane. This results in leakage of cellular contents and ultimately inhibits fungal growth and replication. The 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 fungal cytochrome P450 14-alpha-demethylase, blocking its active site.
2
Inhibition of ergosterol synthesis: This blockade prevents the conversion of lanosterol to ergosterol, a critical component of the fungal cell membrane.
3
Cell membrane disruption: Without ergosterol, the fungal cell membrane becomes fragile and permeable, leading to leakage of essential cellular components.
4
Fungal growth inhibition: The damaged membrane impairs fungal growth and replication, allowing the immune system to clear the infection.

Dosage Information

Adult DosageThe dose of this medicine varies depending on the type and severity of the fungal infection. For vaginal candidiasis, a single 150 mg dose is common. For oral thrush, a typical dose is 200 mg on the first day followed by 100 mg daily for 7-14 days. For esophageal candidiasis, doses may range from 200 mg to 400 mg daily. For cryptococcal meningitis, higher doses are 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 for appropriate dosing in children.
Elderly DosageElderly patients may have reduced renal function, so dose adjustment may be necessary. Monitor renal function and adjust dose accordingly. No specific dose adjustments are recommended based solely on age, but individualization is important.
Renal ImpairmentIn patients with renal impairment, the dose of this medicine should be reduced. For creatinine clearance below 50 mL/min, a reduced dose is recommended. For single-dose therapy, no adjustment is needed. For multiple-dose therapy, the daily dose should be reduced by 50% when creatinine clearance is between 11-50 mL/min, and by 75% when creatinine clearance is below 11 mL/min. Consult your doctor for precise dosing.
Hepatic ImpairmentNo specific dose adjustment is established for hepatic impairment, but this medicine should be used with caution in patients with liver disease. Monitor liver function tests regularly.
Maximum Daily DoseThe maximum daily dose depends on the indication. For most infections, the maximum recommended dose is 400 mg per day, but in severe infections, up to 800 mg per day may be used under medical supervision. Do not exceed the prescribed dose.
