-5%
Ofloxacin 0.3% + Clotrimazole 1% + Beclomethasone 0.025%+ Lidocaine 2% is used in the treatment of ear infection.
Antibacterial: Ofloxacin
- Mechanism of Action: Inhibits DNA gyrase of bacteria, exerting broad-spectrum antibacterial activity.
- Activity Against: Gram-positive bacteria (Staphylococcus aureus, Streptococcus pneumoniae) and Gram-negative bacteria (Escherichia coli, Haemophilus influenzae, Moraxella catarrhalis, Proteus mirabilis, Pseudomonas aeruginosa).
- Clinical Advantage: Effective against otic pathogens without ototoxicity, making it preferable over Aminoglycosides for middle ear infections.
Antifungal: Clotrimazole
- Mechanism of Action: Inhibits Cytochrome P-450 synthesis of Ergosterol, reducing fungal cell wall integrity and inhibiting fungal growth.
- Activity Against: Fungi responsible for superficial mycotic infections, including Candida, Microsporum, and Trichophyton.
- Clinical Advantage: Offers broad-spectrum antifungal activity and also exhibits antibacterial effects against certain bacteria like Streptococci and Staphylococci, beneficial for mixed bacterial-fungal infections.
Anti-inflammatory: Beclomethasone Dipropionate
- Mechanism of Action: Potent steroid with anti-inflammatory, antipruritic, and vasoconstrictive properties.
- Activity: Induces phospholipase A2 inhibition, leading to suppression of inflammatory mediators such as prostaglandins and leukotrienes.
- Clinical Advantage: Provides relief from inflammation associated with otic infections, reducing symptoms like pain and swelling.
Topical Local Anesthetic: Lidocaine Hydrochloride
- Mechanism of Action: Blocks sodium channels, preventing nerve signal transmission and providing local anesthesia.
- Clinical Advantage: Alleviates pain and stinging sensation in the ear, improving patient comfort during treatment.
Formulation and Functionality:
- Designed to maintain the natural environment of the external ear canal.
- Combines antibacterial, antifungal, anti-inflammatory, and local anesthetic agents for effective management of otic infections.
- Each component targets specific aspects of infection, ensuring comprehensive treatment and symptom relief.
