Pharmacological Action

Neomycin sulfate is a broad-spectrum aminoglycoside antibiotic.

It acts bactericidally against gram-positive (Staphylococcus spp., Streptococcus pneumoniae) and gram-negative (Escherichia coli, Shigella dysenteria, Shigella flexneri, Shigella boydii, Shigella sonnei, Proteus spp.) microorganisms; it has low activity against Streptococcus spp.

Polymyxin B is a polypeptide antibiotic.

Active against gram-negative microorganisms: Escherichia coli, Shigella dysenteria, Shigella flexneri, Shigella boydii, Shigella sonnei, Salmonella typhi, Salmonella paratyphi, Pseudomonas aeruginosa.

Not active against Proteus spp., Mycobacterium spp., gram-positive cocci, fungi.

It has a weak local irritant effect.

Lidocaine is a local anesthetic that quickly relieves pain and itching.

Pharmacokinetic studies have not been conducted because the drug is intended for topical use and systemic effects are unlikely.

Dosage Regimen

The method of application and dosage regimen for a specific drug depend on its form of release and other factors. The optimal dosage regimen is determined by the doctor. It is necessary to strictly adhere to the compliance of the dosage form of a specific drug with the indications for use and dosage regimen.

Administer topically into the external auditory canal using the supplied dropper.

For adults, instill 4-5 drops into the affected ear.

For children, instill 2-3 drops into the affected ear.

Apply this dosage 2-4 times daily for adults and 3-4 times daily for children.

Adjust the frequency of administration based on the severity of the condition.

Prior to instillation, warm the bottle by holding it in your hand for a few minutes to avoid vestibular discomfort.

Lie on your side with the affected ear upward.

Gently pull the auricle upward and backward to straighten the ear canal.

Instill the prescribed number of drops.

Maintain this position for several minutes to facilitate penetration.

A small piece of cotton wool may be placed loosely in the ear opening.

The total duration of treatment must not exceed 7 days.

Do not use the medication for prolonged periods.

Discontinue use if no clinical improvement is observed within the treatment week.

Do not share the dropper to prevent cross-contamination.

Avoid touching the dropper tip to the ear or any other surface.

Adverse Reactions

Local allergic reactions such as hyperemia, itching, and peeling of the skin of the external auditory canal are possible, which disappear without treatment after discontinuation of the drug.

Systemic effects are unlikely due to the low doses of the drug used.

However, with prolonged treatment, systemic side effects may occur, in particular, ototoxicity and nephrotoxicity due to the absorption of neomycin.
