 0.3%+1%+0.025%+2% Ear Drop
Opsonin Pharma Ltd.

5 ml drop: ৳ 150.00

Indications

This combination is indicated for the treatment of mixed bacterial and fungal infections with associated inflammation and pain, particularly:

  • Otitis externa (external ear infection): Caused by susceptible bacteria and fungi.
  • Superficial skin infections: Where bacterial and fungal pathogens coexist with inflammation.
  • Symptomatic relief of pain and itching: In infected and inflamed skin or ear canal.

Off-label uses (clinically accepted):

  • Adjunct therapy for otomycosis with secondary bacterial infection.
  • Inflammatory dermatoses complicated by mixed infections.
Dosage & Administration
  • Route: Topical application (ear drops or skin cream/ointment depending on formulation).
  • Adults and adolescents (≥12 years):
    • Ear drops: Instill 3–4 drops into the affected ear 2–3 times daily for 7–14 days.
    • Skin application: Apply a thin layer 2–3 times daily to the affected area.
  • Pediatrics (≥2 years): Use with caution and under medical supervision; dosing generally similar to adults but may be adjusted.
  • Elderly: No specific dose adjustment required.
  • Special populations:
    • Renal or hepatic impairment: No dose adjustment necessary due to minimal systemic absorption.
    • Avoid use if tympanic membrane perforation is suspected unless prescribed by a healthcare professional.
  • Duration: Usually 7–14 days depending on clinical response. Avoid prolonged use to prevent adverse effects.
  • Administration tips: Clean and dry the affected ear or skin area before applying medication. Avoid contamination of the dropper or applicator tip.
Mechanism of Action (MOA)
  • Ofloxacin: A fluoroquinolone antibiotic that inhibits bacterial DNA gyrase and topoisomerase IV enzymes, preventing bacterial DNA replication and transcription, leading to bacterial cell death.
  • Clotrimazole: An antifungal agent that inhibits lanosterol 14-α-demethylase, an enzyme involved in ergosterol synthesis, disrupting fungal cell membrane integrity and causing cell death.
  • Beclomethasone: A corticosteroid that binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, reduce edema, and alleviate itching.
  • Lidocaine: A local anesthetic that blocks voltage-gated sodium channels on nerve membranes, inhibiting nerve impulse conduction and providing rapid pain relief.

Together, these agents eradicate bacterial and fungal infections, reduce inflammation, and relieve pain and itching.

Pharmacokinetics
  • Absorption: Minimal systemic absorption when applied topically.
  • Distribution: Primarily localized to the site of application.
  • Metabolism:
    • Ofloxacin undergoes minimal metabolism; topical use limits systemic exposure.
    • Clotrimazole is metabolized hepatically if systemically absorbed, but topical use results in negligible systemic levels.
    • Beclomethasone is metabolized locally in skin and systemically in the liver if absorbed.
    • Lidocaine is metabolized in the liver, but systemic absorption is negligible with topical use.
  • Elimination: Mostly renal excretion for absorbed ofloxacin; negligible systemic elimination for topical use of other components.
  • Onset: Lidocaine provides analgesia within minutes; antimicrobial and anti-inflammatory effects develop over days with consistent use.
Pregnancy Category & Lactation
  • Pregnancy:
    • Use only if clearly needed and benefits outweigh risks.
    • Ofloxacin is FDA category C; fluoroquinolones generally avoided during pregnancy due to potential fetal risks.
    • Clotrimazole topical use is considered low risk.
    • Beclomethasone topical use in pregnancy is generally considered low risk but should be used cautiously.
    • Lidocaine topical use is considered relatively safe.
  • Lactation:
    • Minimal systemic absorption suggests low risk to nursing infants.
    • Use with caution; avoid applying on or near the breast to prevent infant exposure.
  • Note: Limited human data; use under medical supervision.
Therapeutic Class
  • Combination topical antimicrobial and anti-inflammatory agent with local anesthetic.
  • Components:
    • Ofloxacin: Fluoroquinolone antibiotic
    • Clotrimazole: Imidazole antifungal
    • Beclomethasone: Topical corticosteroid
    • Lidocaine: Local anesthetic
Contraindications
  • Hypersensitivity to ofloxacin, clotrimazole, beclomethasone, lidocaine, or any formulation excipients.
  • Known or suspected tympanic membrane perforation (unless specifically prescribed).
  • Viral infections of the skin or ear (e.g., herpes simplex).
  • Tuberculous infections of the ear or skin.
  • Untreated fungal infections without appropriate antifungal therapy.
Warnings & Precautions
  • Avoid prolonged use to prevent corticosteroid-induced skin thinning or secondary infections.
  • Use with caution in patients with a history of hypersensitivity to any component.
  • Discontinue if signs of hypersensitivity or worsening infection develop.
  • Avoid contact with eyes and mucous membranes.
  • Monitor for local irritation or allergic reactions.
  • Not recommended for use in infants under 2 years unless prescribed.
  • Avoid use if ear discharge or tympanic membrane perforation is suspected without medical advice.
Side Effects
  • Common:
    • Mild burning, stinging, itching, or irritation at the application site.
    • Dryness or redness.
  • Serious/Rare:
    • Allergic reactions such as rash, urticaria, or anaphylaxis.
    • Secondary infections due to immunosuppression from corticosteroid.
    • Local skin atrophy or telangiectasia with prolonged use.
    • Rare systemic toxicity from lidocaine if absorbed in large amounts.
  • Onset: Usually occurs within minutes to days after starting therapy; dose-dependent.
Drug Interactions
  • Minimal systemic absorption reduces the likelihood of systemic drug interactions.
  • Avoid concomitant use with other ototoxic or topical corticosteroid agents.
  • Clotrimazole may inhibit CYP3A4 enzymes moderately, but topical use is unlikely to cause significant interactions.
  • Caution with other local anesthetics to avoid additive toxicity.
  • Avoid alcohol consumption if irritation or systemic absorption is suspected.
Recent Updates or Guidelines
  • Current otitis externa management guidelines support combined antimicrobial and corticosteroid therapy for effective symptom control.
  • Emphasis on limiting corticosteroid use duration to minimize side effects.
  • No recent changes in approved indications or dosing protocols reported.
  • Monitoring for antimicrobial resistance is advised with fluoroquinolone use.
Storage Conditions
  • Store at 20°C to 25°C (68°F to 77°F).
  • Protect from light, moisture, and excessive heat.
  • Keep the container tightly closed.
  • Do not freeze.
  • Shake well before use if the product is a suspension.
