Lacri is a composition solution very similar to the natural tear, based on sodium carboxymethylcellulose, a salt derived from cellulose. Tear-mimicking formulations should be used when the quantity or quality of tears is altered or when tear loss occurs due to increased evaporation. Dry keratoconjunctivitis or “dry eye” is a frequent ophthalmic problem in dogs that usually results from a deficiency in the aqueous component of the tear film. Lacri helps to lubricate the eyes, improving the symptoms of dry eyes.

It is the veterinary Division of União Química Farmacêutica Nacional, a Brazilian company with more than 80 years of history in the pharmaceutical market.
