What is Ketoconazole and its Mechanism of Action?

Ketoconazole is an antifungal medication. It works by inhibiting the synthesis of ergosterol, a vital component of fungal cell membranes.

Specifically, ketoconazole blocks the cytochrome P450 enzyme system (CYP51) in fungi. This enzyme is responsible for converting lanosterol to ergosterol. By inhibiting this enzyme, ketoconazole prevents the fungi from producing ergosterol, leading to disruption of their cell membranes and ultimately, fungal cell death.

This mechanism is highly specific to fungi; ketoconazole’s effect on human cytochrome P450 enzymes is significantly less pronounced, although drug interactions are still possible.

Important Note: Ketoconazole’s use is increasingly restricted due to concerns regarding liver toxicity and drug interactions. Always consult a doctor before using this medication.

Remember to follow your doctor’s instructions carefully regarding dosage and duration of treatment.

Ketoconazole 200mg Dosage and Administration

Always follow your doctor’s instructions precisely. A typical dosage for oral ketoconazole 200mg tablets is one tablet daily, taken once a day. However, your doctor might adjust this based on your specific condition and response to treatment.

Timing is important. Take the tablet with food to improve absorption. This means taking it during or after a meal. Consuming grapefruit juice while taking ketoconazole should be avoided, as it can interfere with absorption.

The duration of treatment varies depending on the infection being treated. Your doctor will determine the appropriate treatment length. Complete the entire course of medication, even if you feel better before the prescribed time. Stopping early may lead to recurrence of the infection.

Certain medications can interact with ketoconazole. Inform your doctor about all medications, including over-the-counter drugs and herbal supplements, you are currently taking. This ensures your safety and treatment efficacy.

Possible Side Effects	What to Do
Nausea, vomiting, diarrhea	These are common, usually mild, and often resolve on their own. Inform your doctor if symptoms are severe or persistent.
Headache, dizziness	These are relatively common. Report any severe or persistent headaches or dizziness.
Liver problems (rare but serious)	Seek immediate medical attention if you experience jaundice (yellowing of skin or eyes), dark urine, or abdominal pain.

Regular monitoring of liver function may be necessary, particularly with prolonged use. Your doctor will discuss this with you if required. Always consult your doctor or pharmacist if you have any questions or concerns regarding your ketoconazole 200mg treatment.
