Itraconazole Oral Solution 100 mL for Cat

Itraconazole Oral Solution 100 mL for cats is a broad-spectrum antifungal medication used to treat both superficial and systemic fungal infections. Its liquid formulation allows accurate weight-based dosing, making it especially useful for kittens, small cats, and long-term therapy cases. Itraconazole belongs to the triazole class of antifungals and is widely regarded as a first-line treatment for many feline fungal infections when prescribed and monitored by a veterinarian.

Key Benefits

• Broad-spectrum antifungal coverage
• Effective for skin and systemic infections
• Liquid formulation for precise dosing
• Better absorption when given with food
• Once-daily dosing in most cases
• Preferred over older antifungals due to improved safety profile

How Itraconazole Works

Itraconazole inhibits the fungal enzyme lanosterol 14α-demethylase, blocking ergosterol synthesis. Without ergosterol:

• Fungal cell membranes weaken
• Growth and replication stop
• Fungal cells eventually die

Its long half-life and strong tissue penetration make it particularly effective for persistent infections.

Indications in Cats

Itraconazole Oral Solution is commonly prescribed for:

1. Dermatophytosis (Ringworm)

• Microsporum canis
• Trichophyton species
• Especially in multi-cat homes or shelters

2. Cryptococcosis

• Early CNS infections

3. Histoplasmosis

4. Aspergillosis
