A-CYST is a patented formulation designed for temporary replenishment of the glycosaminoglycan (GAG) layer in the urinary bladder. A-CYST contains naturally occurring components of the GAG layer of bladder epithelium. The GAG layer normally provides a protective barrier against microorganisms, carcinogens, crystals and other agents present in urine. The GAG layer has been identified as a primary defense mechanism from these irritants. Deficiencies in the GAG layer may affect epithelial barrier function and allow adherence of bacteria, microcrystals, proteins and ions, or movement of solute residues (i.e., urea).

The GAG layer of the bladder is deficient in cystitis. GAG deficiency contributes to clinical symptoms in diseases such as feline idiopathic cystitis (FIC), feline lower urinary tract disease (FLUTD), and cystitis caused by infections, trauma, urolithiasis, urinary retention and neoplasia. A-CYST has been designed for use in cystitis to temporarily coat and help replenish the deficient GAG layer on bladder epithelium.
