Quote from booklet - Chronic Pancreatitis about Enzyme Supplements:
'There are many preparations available. These preparations differ considerably in their effectiveness of action. The better preparations consist of capsules containing scores of small granules. The enzyme preparations can also be divided into two types depending upon their strength of action: regular and high dose. The capsules need to be taken during each meal and with any snack. Requirements vary enormously from patient to patient: typically 20-30 high-dose capsules per day are required but this can be lower or much higher. The requirementsvary greatly from patient to patient partly because of the different level of secretion by any functioning pancreas and partly because there are still some enzymes secreted by the salivary glands, tongue, stomach and small intestines but which also varies greatly from person-to-person In a few cases of children and adults with cystic fibrosis, a serious problem with the large bowel (colon) has been reported. This condition is called fibrosing colonopathy and causes narrowing of the bowel. It seems to be related to the use of a particular acid-resistant coating of the enzyme preparations (called methacrylic copolymer). The problem does not arise with preparations without this covering. The latter preparations are therefore recommended. The ingredients are always listed on the pack leaflet or label. Once patients are accustomed to taking enzyme supplements, they are usually allowed to adjust the number they take themselves to suit their own individual needs'.

The pancreas serves two functions: producing hormones and secreting digestive enzymes. A normally functioning pancreas secretes about 8 cups of fluid daily into the portion of the small intestine that connects with the stomach, called the duodenum. This fluid, referred to as pancreatic juice, helps neutralize stomach acid as it enters the small intestine. It also contains pancreatic enzymes.
Pancreatic enzymes help to break down fats, proteins, and carbohydrates. Pancreatic enzyme supplements are necessary when the pancreas does not produce enough enzymes on its own to break down food. Having an insufficient amount of pancreatic enzymes is very common among those with pancreatic cancer. For those who have had the Whipple procedure to surgically remove a pancreatic tumor, malabsorption is an issue since fat absorption cannot be completely restored to normal.
Types of Pancreatic Enzymes and Their Effects
|Enzyme Type||Effects||A shortage may cause:|
|Lipase||Lipase works with bile from the liver to break down fat molecules so they can be absorbed and used by the body.||Lack of needed fats and fat-soluble vitamins.|
|Proteases||Proteases break down proteins. They help keep the intestine free of parasites such as bacteria, yeast, and protozoa.||
Incomplete digestion of proteins resulting in allergies or the formation of toxic substances.
Increased risk for intestinal infections.
|Amylase||Amylase breaks down carbohydrates (starch) into sugars which are more easily absorbed by the body. This enzyme is also found in saliva||Diarrhea due to the effects of undigested starch in the colon.|
Reasons to Take Pancreatic Enzymes
Doctors sometimes prescribe digestive enzymes, including pancreatic enzymes, to improve digestion and absorption of food in conditions that cause poor absorption. Some of these conditions are:
- pancreatic insufficiency
- following the Whipple procedure
- following a total pancreatectomy (complete removal of the pancreas)
- blockage or narrowing of the pancreatic or biliary duct (the tubes that carry pancreatic juice or bile)
- pancreatic or duodenal tumors
- cystic fibrosis
Pancreatic insufficiency is the inability of the pancreas to secrete the enzymes needed for digestion. Mild forms of pancreatic insufficiency are fairly common, especially in older adults, and can also play a major role in many cases of food allergies. It is common in pancreatic cancer patients and may cause feelings of indigestion, cramping after meals, large amounts of gas, foul smelling gas or stools, floating or greasy/fatty stools, frequent stools, loose stools, and weight loss. Pancreatic enzyme supplements should be considered for these patients.
The Whipple procedure is the most commonly used operation for removing a pancreatic tumour. About 25% of patients who have the Whipple procedure suffer from malabsorption. Fat absorption usually cannot be restored to normal in these patients. In this case, the goal is to eliminate diarrhea, restore adequate nutrition, and prevent weight loss. A dose of enzyme supplements containing 30,000-40,000 units of lipase at each meal may help achieve these results.
In patients with advanced cancer in the head of the pancreas with pancreatic duct obstruction that cannot be surgically removed, a combination of pancreatic enzyme replacement therapy, nutritional counselling, and drainage of the bile duct can prevent weight loss.
Sources of Pancreatic Enzymes
Supplemental pancreatic enzymes are available as prescription and non-prescription forms. (Certainly in America). The amount of each enzyme varies greatly between the different brands of tablets. The United States Food and Drug Administration (FDA) has mandated that all pancreatic insufficiency drugs obtain FDA approval by 2008 to help regulate formulations, dosage, and potency of these products. However, current production of enzyme supplements is not standardized; therefore, one brand may not be equivalent to another.
The recommended type and dosage of pancreatic enzymes must be individualized for each person. When the patient finds a brand that works, it is suggested that he or she stick with that brand. Most people start by taking one pill with snacks and two with meals and increase or decrease the dose as needed. Some individuals may adapt to different doses of enzymes throughout their care. It is important to discuss with a doctor or dietitian the appropriate type and dose of pancreatic enzymes at regular visits.
Available by prescription (some only available in America).

Taking Pancreatic Enzymes
An acid-reducing medication may be prescribed by the
doctor to help improve the effectiveness of pancreatic enzyme supplements. Acid
reducing medications include proton pump inhibitors and H2 blocker. Tips
to obtain the best results from pancreatic enzymes:.
a) Take enzymes with every meal or snack that contains fat, especially meat, dairy, bread, snacks, and desserts.
b) Start with the smallest dose necessary. Adjust according to the severity of the pancreatic insufficiency. Further alterations may be needed from
time to time.
c) Take the enzymes at the beginning of the meal or snack. This is very important for proper enzyme functioning. When taking multiple enzymes,
they should be taken at the beginning, middle, and end of the meal. Enzymes generally do not work well if forgotten and only taken at the end
of the meal.
d) Swallow intact tablets with liquid at mealtimes. Some enzyme supplements have a special coating to prevent breakdown in the stomach. The
tablets should not be crushed or chewed unless you are directed by a member of your medical team.
e) Certain enzymes that are present in pancrelipase may begin to digest the mucous membranes and cause irritation if retained in the mouth. This
can lead to ulcerations of the mouth, lips, and tongue. If swallowing a capsule is difficult, open the capsule and add the entire capsule of
microspheres to a spoonful of soft food that does not require chewing and can be swallowed immediately. Some recommended foods are
applesauce, gelatin, pureed apricot, banana or sweet potatoes.
f) Promote enzyme function by not mixing the open capsules with milk, custard, ice cream, and other dairy products. These foods have a higher
pH that may dissolve the capsule's coating and destroy enzyme activity before they reach the stomach.
g) Pancreatic enzymes may have reduced effectiveness if taken with calcium- or magnesium-containing antacids.
Side Effects of Pancreatic Enzymes
The most common side-effect of pancreatic enzymes is constipation. However, it is possible for enzymes to cause nausea, abdominal cramps, or diarrhoea, though these symptoms are uncommon.
Discontinue the use of pancreatic enzymes if any signs of hypersensitivity or allergic reaction appear. Beef, pork, pineapple, and/or papaya may all be used in the preparation of enzymes. Therefore, individuals with allergies to any of these foods should work with their pharmacist and doctor to find an appropriate enzyme preparation. In addition, pancreatic enzymes may influence the effectiveness of some diabetic medications, and possible drug interactions exist with antacids and iron. Notify the patient's doctor and registered dietitian of all current medications and medical conditions while discussing the use of pancreatic enzymes.
If taken properly, pancreatic enzymes can help prevent weight loss and control symptoms associated with pancreatic enzyme insufficiency. Ask the patient's doctor to prescribe the proper pancreatic enzymes.
Pancreatic Enzymes and their suitability to those of us who are
Muslims, Jews or Vegetarians
In answer to an email I sent to Mike Larvin, our Patron about the suitability of Pancreatic Enzymes to the above members of our society, the list is not exclusive only meant as an example of members who could be affected.
We have many patients who cannot eat pork meat for religious reasons (Jewish and Muslim). Our Imrans in the UK and in the Middle-East have told us that the restrictions written in the Koran only applies to eating edible parts of a pig - the enzymes are chemically extracted from the pancreas and are not considered a foodstuff. They are chemically similar to human enzymes and no pig cells survive the extraction process. Therefore they advise our patients that it is allowed. I have lectured in Malaysia and this was confirmed as acceptable by Gastroenterologists of the Muslim faith. The same applies to Insulin when it is mainly made from a pig source. The metabolism of pigs is closer to human than bovine (bull or cow) which is the alternative.
(Since this email was written we now have the human insulins which are totally manufactured. Jim Armour, Chairman)
