Sodium Bicarbonate [Ear Preparations]


Ear drops is indicated as an aid to soften and in the removal of hardened ear wax from the ear canal.


Ear wax which often obstructs the external auditory meatus of the ear contains less than 50% of fatty matter derived from secretions of the sebaceous ceruminous glands. The majority of the wax consists of desquamated epithelium, foreign matter and shed hairs. This non-fatty material forms a matrix holding together the granules of fatty matter to form the ceruminous mass. The addition of oils or solvents binds the mass more firmly together, but aqueous solutions, if they are able to penetrate the matrix, cause a disintegration of the ceruminous mass. Sodium bicarbonate ear drops actively dissolves the wax rapidly by penetrating the dry matrix of the ceruminous mass, reducing the solid ear wax to a Semi-Solid debris. It is a quicker, more effective method for wax removal.
