PreOtic SQ has ceruminolytic properties that allow effective cleansing of the ear canals from pathological discharge and earwax.
Otitis externa is frequently encountered in veterinary practice. Its causes may include various conditions: parasites, disorders of cornification, hypersensitivity, endocrinopathies, neoplasia and other diseases. Secondary bacterial and yeast infections are common complications of otitis. As infections progress, other structures may become involved, including the middle ear cavity, and internal otitis may also develop.
The most common pathogens in infectious otitis are Staphylococcus intermedius, Pseudomonas aeruginosa and Malassezia pachydermatis.
Ear canal cleansing is an important part of otitis therapy. It helps remove discharge and pus, which is especially important before using products with components that may be inactivated in a purulent environment, such as polymyxin. Small foreign objects and bacterial toxins may also be washed out during cleansing.
Cleansing is also performed to help prevent recurrence of otitis in chronic diseases, as well as in clinically healthy animals to facilitate the removal of earwax.
A wide range of ear cleaning products is available on the veterinary market. There are three main types of cleaning agents: ceruminolytic cleansers, mild care cleansers that make up the majority of products, and antiseptic or drying lotions.
Ceruminolytic cleansers mainly contain more effective ceruminolytic components that usually irritate the ear canal if left in the canal for an extended period and therefore should be rinsed out after use. These types of cleansers are more often used in clinics during therapeutic flushing.
Ceruminolytic components significantly facilitate and accelerate the cleaning procedure because they are strong surfactants and detergents that act by emulsifying waxy and lipid substances in earwax. The emulsified material is more easily washed out of the ear canal.
Squalene is an organic triterpene molecule that is a precursor of cholesterol and all steroid hormones. It is naturally found in the skin; it is likely one of the few ceruminolytic ingredients that are safe for different ear structures and can be left in the canal without the need for rinsing.
As a ceruminolytic, squalene significantly facilitates and accelerates the cleaning procedure because it turns waxes and lipids into an easily washable emulsion. Studies have shown that this ingredient does not cause proliferative changes in the middle ear and is therefore permitted in cases of tympanic membrane perforation. Squalene can be used in different concentrations, and its ceruminolytic properties increase as the concentration increases.
