ECOZOLE PESSARY

Indications

• Tinea pedis (athlete's foot)
• Tinea corporis (ringworm)
• Tinea cruris (jock itch)
• Candidiasis (cutaneous candidiasis)
• Pityriasis versicolor
• Seborrheic dermatitis

Dosage

Children: Refer to specific product labeling or consult a healthcare professional for appropriate dosing regimens in children, as pediatric dosing should be

Adults: Refer to specific product labeling or consult a healthcare professional for appropriate dosing regimens, as these can vary based on the formulation and severity of infection.

Mechanism of action

Econazole exerts its antifungal effect by inhibiting the enzyme lanosterol 14-alpha-demethylase, which is crucial in the biosynthesis of ergosterol. This action disrupts the integrity of the fungal cell membrane, causing leakage of essential intracellular components and ultimately leading to cell lysis and death. Additionally, econazole may have anti-inflammatory properties, aiding in the reduction of associated symptoms.

Pharmacodynamics

Econazole exhibits fungicidal activity against a wide spectrum of fungi, including dermatophytes and Candida species. Its antifungal effectiveness is characterized by a dose-dependent response, where higher concentrations result in more pronounced antifungal activity. The drug is generally well-tolerated, with side effects usually being localized to the application site, such as irritation or allergic reactions.

Pharmacokinetics

When administered topically, econazole is minimally absorbed into systemic circulation, resulting in low plasma concentrations. The drug achieves high local concentrations at the site of application, which is beneficial for treating localized infections. The half-life of econazole in the skin can vary, but due to its limited systemic absorption, it maintains therapeutic levels locally for extended periods. Metabolism primarily occurs in the liver, with excretion mainly via the feces.

Contra-indications

• Hypersensitivity to ecozole or any of its components
• Severe liver impairment
• Pregnancy

Adverse effects

• Nausea
• Headache
• Dizziness
• Abdominal pain
• Rash
• Hepatotoxicity
• Allergic reactions

Interactions

• CYP450 enzyme inducers (e.g., rifampicin, phenytoin) may decrease the effectiveness of ecozole
• CYP450 enzyme inhibitors (e.g., ketoconazole, erythromycin) may increase levels of ecozole
• Concurrent use with anticoagulants may enhance anticoagulant effects

Precautions

• Use with caution in patients with liver disease
• Monitor liver function tests during treatment
• Assess for potential drug interactions due to polypharmacy

Pregnancy

Use is contraindicated in pregnancy due to potential fetal harm.

Breast-feeding

Use with caution, as it may be excreted in breast milk and affect the nursing infant.

Storage

Store at room temperature, away from moisture and heat. Keep out of reach of children.
