Otek AC Ear Drop is a fixed-dose combination medicine formulated for the management of ear infections involving both fungal and inflammatory components. The preparation typically contains Clotrimazole 1% w/v, Lignocaine Hydrochloride 2% w/v, and Beclomethasone Dipropionate 0.025% w/v. Each component has a specific role in controlling infection, reducing inflammation, and providing symptomatic relief.

Clotrimazole is an antifungal agent belonging to the imidazole class of medicines. It acts by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes. The absence of ergosterol disrupts membrane integrity, causing leakage of intracellular contents and eventual fungal cell death. This makes the ear drop effective in treating otomycosis, a common fungal infection of the external auditory canal.

Lignocaine Hydrochloride is a local anesthetic included to relieve pain and itching associated with ear infections. It works by blocking sodium channels in neuronal cell membranes, preventing nerve impulse transmission and producing temporary numbing of the affected area. This helps reduce discomfort, irritation, and burning sensations in the ear.

Beclomethasone Dipropionate is a corticosteroid used for its anti-inflammatory and anti-allergic actions. It works by inhibiting the release of inflammatory mediators such as prostaglandins and leukotrienes. This reduces swelling, redness, and fluid discharge in the external ear canal. The corticosteroid component helps control inflammation that often accompanies fungal or mixed ear infections.

Otek AC Ear Drop is commonly used in conditions such as otitis externa, otomycosis, and ear canal inflammation caused by microbial overgrowth. The combination targets multiple symptoms including pain, itching, swelling, and fungal proliferation. The ear drop formulation is designed for easy administration directly into the external auditory canal, allowing localized action at the site of infection.

The solution is generally clear to slightly viscous and packaged in a plastic dropper bottle to ensure controlled dispensing. Storage requirements typically include keeping the bottle tightly closed, protected from direct light, and at room temperature to maintain stability.
