Lamisil: Pharmacokinetics and Drug Interactions

Lamisil, a widely used antifungal medication, exhibits specific pharmacokinetic properties that contribute to its efficacy and safety profile. Understanding the absorption, distribution, metabolism, and excretion (ADME) of Lamisil is crucial for optimizing its therapeutic use and assessing potential drug interactions.

Absorption

When administered orally as tablets, Lamisil is rapidly absorbed from the gastrointestinal tract. Approximately 40-80% of an oral dose is systemically bioavailable due to significant first-pass metabolism in the liver. Food intake has no significant effect on the absorption of Lamisil, making it suitable for administration regardless of meals.

In topical form, such as cream or gel, Lamisil is applied directly to the affected area. The drug penetrates the skin efficiently, reaching therapeutic concentrations in the superficial layers where most fungal infections occur.

Distribution

Lamisil has a high affinity for keratin-rich tissues, such as skin, hair, and nails, which are frequent targets of fungal infections. This preferential distribution allows Lamisil to accumulate in these tissues, exerting its antifungal effects directly at the site of infection.

The drug also exhibits moderate binding to plasma proteins (approximately 99%) but has a low volume of distribution, indicating limited extravascular penetration and distribution to other organs.

Metabolism

Lamisil undergoes extensive hepatic metabolism primarily via the cytochrome P450 enzyme CYP2C9, with minor contributions from CYP1A2 and CYP3A4. The main metabolite, known as desmethylterbinafine, also possesses antifungal activity and contributes to the overall efficacy of Lamisil.

Metabolism of Lamisil may be affected by drug interactions with CYP2C9 inhibitors, such as fluconazole or cimetidine, which can lead to increased plasma concentrations and the potential for enhanced efficacy or adverse effects.

Excretion

Lamisil and its metabolites are primarily eliminated through the kidneys, with approximately 70-80% of a dose excreted in the urine. The elimination half-life of Lamisil ranges from 16 to 18 hours, allowing for once-daily dosing in most cases.

Prompt renal excretion makes Lamisil a suitable option for patients with impaired liver function, as the drug is not extensively cleared by the liver. However, dose adjustments may be necessary in individuals with significant renal impairment or end-stage renal disease.

Drug Interactions

Lamisil has a relatively low potential for drug interactions compared to other antifungal medications. However, caution should be exercised when co-administering Lamisil with drugs that inhibit or induce the CYP2C9 enzyme.

Medications such as fluconazole, which inhibit CYP2C9, can increase the plasma levels of Lamisil, potentially leading to an increased risk of adverse effects. On the other hand, CYP2C9 inducers, like rifampin, may reduce the plasma concentrations of Lamisil, compromising its antifungal efficacy.
