When cats suffer from the condition Exocrine Pancreatic Insufficiency, their pancreas fails to excrete enough of the digestive enzymes needed for proper digestion of food. Some of the enzymes are: lipases, to digest fats; amylase, to digest starch/sugars; and proteases, to digest proteins. Even though the cat is eating enough food, and in many cases much more than enough, it is literally starving. Without enzymes to break down the food eaten, nutrients cannot be absorbed. If they can't be absorbed, they can't be utilized by the body. PanaKare Plus tablets are a pancreatic enzyme concentrate of porcine origin fortified with the fat soluble vitamins A, D and E and is used as a digestive aid in replacement therapy where digestion of protein, carbohydrates and fat is inadequate due to exocrine pancreatic insufficiency.
