Usage
- This drug combination is prescribed for impacted earwax (cerumen) and keratosis obturans (a rare condition where the ear canal is blocked with a keratin plug).
- Pharmacological classification: Cerumenolytic, local anesthetic, antiseptic, and counterirritant.
- Mechanism of Action: The combined effect of paradichlorobenzene (cerumenolytic), benzocaine (local anesthetic), and chlorbutol (antiseptic and mild local anesthetic) softens earwax, reduces pain and discomfort, and provides mild antisepsis.
Alternate Names
- No internationally recognized alternate names.
- Brand names include Otiflox WX, Clearwax, Soliwax, Curewax and others.
How It Works
- Pharmacodynamics: Paradichlorobenzene softens and dissolves earwax. Benzocaine provides local anesthesia by blocking nerve conduction, reducing pain sensation. Chlorbutol acts as a mild antiseptic and local anesthetic.
- Pharmacokinetics: Absorption is minimal with topical otic administration. Metabolism and elimination pathways for this combination are not well-documented. Limited systemic absorption is expected.
