Indications

• Pancreatitis
• Salivary gland disorders
• Carbohydrate malabsorption syndromes

Dosage

Children: Refer to the BNF for Children for appropriate dosing information.

Adults: Refer to the specific guidelines and dosing recommendations in the BNF.

Mechanism of action

Amylase facilitates the breakdown of starch and glycogen into maltose and dextrins by cleaving the α-1,4-glycosidic bonds in these polysaccharides. Its action begins in the mouth with salivary amylase and continues in the small intestine with pancreatic amylase, where it further digests carbohydrates.

Pharmacodynamics

Amylase increases the rate of carbohydrate digestion, thereby influencing blood glucose levels. The enzyme's activity can be affected by pH levels, temperature, and the presence of inhibitors or activators. In clinical settings, elevated levels of amylase in the blood can indicate pancreatitis or other pancreatic disorders.

Pharmacokinetics

Amylase is absorbed and metabolized in the gastrointestinal tract. Its activity is measured through serum levels, with normal ranges indicating proper pancreatic function. The half-life of amylase in the bloodstream can vary based on individual metabolic rates and health conditions.

Pregnancy

Amylase is generally considered safe during pregnancy but should be used under medical supervision.

Breast-feeding

Amylase is excreted in breast milk; it is advisable to consult a healthcare provider before use while breastfeeding.

Adults: Refer to appropriate guidelines for specific dosage; generally taken with adequate fluid intake.

Mechanism of action

Cellulose acts primarily as a bulk-forming laxative. It absorbs water in the intestines, which increases stool bulk and stimulates peristalsis, thus facilitating bowel movements. Additionally, cellulose is not digestible by human enzymes, leading to fermentation by gut bacteria, which may enhance gut health and alter gut microbiota composition.

Pharmacodynamics

Cellulose increases stool weight and frequency of bowel movements. It works by retaining water in the intestines, leading to softer stools and improved passage through the gastrointestinal tract. The bulking effect of cellulose can help alleviate constipation and promote overall digestive health. It may also play a role in cholesterol reduction and glycemic control through its effects on digestion and absorption of nutrients.

Pharmacokinetics

Cellulose is not absorbed into the bloodstream due to its indigestible nature. Instead, it passes through the gastrointestinal tract, where it adds bulk to the stool. Its fermentation by colonic bacteria produces short-chain fatty acids, which may have beneficial effects on colon health. The onset of action for cellulose as a laxative can vary but is generally within 24 to 72 hours after ingestion.

Adverse effects

• Bloating
• Flatulence
• Diarrhea
• Abdominal discomfort

Precautions

• Use with caution in patients with a history of gastrointestinal disorders.
• Monitor for potential allergic reactions in sensitive individuals.

Pregnancy

Cellulose is generally considered safe during pregnancy as it is a non-toxic, indigestible fiber.

Breast-feeding

Cellulose is also considered safe during breastfeeding; it is excreted in breast milk in negligible amounts.

Storage

Store in a cool, dry place away from direct sunlight.

Mechanism of action

Lipase hydrolyzes triglycerides into diglycerides and free fatty acids. This process occurs in the presence of bile salts, which emulsify fats, allowing lipase to effectively access and break down lipid molecules. The free fatty acids produced can then be absorbed by the intestinal mucosa and transported into the bloodstream.

Pharmacodynamics

Lipase enhances the digestion of dietary fats, facilitating their absorption. The activity of lipase is pH-dependent, with optimal function occurring in the alkaline environment of the small intestine. The enzyme's activity can be influenced by factors such as dietary composition and the presence of bile salts. Elevated levels of lipase in the bloodstream can indicate pancreatic inflammation or damage, such as in cases of pancreatitis.

Pharmacokinetics

Lipase is not absorbed systemically; it functions locally in the gastrointestinal tract. The enzyme is secreted by the pancreas and acts in the small intestine. Its activity can be affected by gastrointestinal transit time and the presence of other digestive enzymes. The half-life of lipase in the gastrointestinal tract is dependent on dietary intake and gastrointestinal motility.

Adverse effects

• Abdominal cramping
• Diarrhea
• Nausea
• Vomiting
• Allergic reactions

Precautions

• Use with caution in patients with a history of pancreatitis
• Monitor for signs of allergic reactions
• Evaluate dietary fat intake in patients receiving lipase therapy

Pregnancy

Lipase is generally considered safe during pregnancy, but should be used under medical supervision.

Breast-feeding

Lipase can be used while breastfeeding, although it is advisable to consult a healthcare provider.

Storage

Dosage

Children: Not applicable, as pectinase is not used therapeutically in children.

Adults: Dosage is highly variable depending on the application and specific product used. Refer to the product label for manufacturer-recommended dosing guidelines.

Mechanism of action

Pectinase acts by hydrolyzing the pectin molecules, which leads to the degradation of the plant cell wall structure. This enzymatic activity results in the release of juice and the clarification of liquids by reducing turbidity caused by suspended particles.

Pharmacodynamics

The pharmacodynamic effects of pectinase are primarily related to its enzymatic activity. It improves the extraction yield of juices and enhances the quality of beverages and food products by modifying the viscosity and stability. Its effects are dose-dependent and vary based on the concentration of pectin in the substrate and the specific conditions of the reaction such as pH and temperature.

Pharmacokinetics

Pectinase is typically administered in an industrial setting rather than as a therapeutic agent. As such, traditional pharmacokinetic parameters such as absorption, distribution, metabolism, and excretion are not typically applicable. When used in food processing, the enzyme acts locally at the site of application and does not accumulate in the body.

Pregnancy

Pectinase is generally considered safe for use during pregnancy, but consult a healthcare provider before use.

Breast-feeding

Pectinase is likely safe during breastfeeding, but it is advisable to seek medical advice.

Storage

Store in a cool, dry place away from direct sunlight. Keep container tightly closed.

Adults: Refer to specific product guidelines and formulations as dosages can vary widely based on application and formulation.

Mechanism of action

Phytase works by cleaving the phosphate groups from phytic acid, resulting in the release of free phosphate. This process not only increases the availability of phosphorus for absorption in the intestines but also reduces the environmental impact of phosphorus excretion in livestock. The enzyme operates optimally at specific pH levels, often functioning best in acidic to neutral conditions.

Pharmacodynamics

Phytase contributes to improved nutrient absorption in the gastrointestinal tract, leading to enhanced growth performance in animals. In humans, it may aid in the digestion of phytate-rich foods, potentially improving the bioavailability of essential minerals such as calcium, magnesium, and iron. The activity of phytase can vary based on the source of the enzyme and the substrate present.

Pharmacokinetics

Phytase is not absorbed systemically; its action is localized within the gastrointestinal tract. The kinetics of phytase can vary depending on the formulation and the presence of other dietary components. The enzyme is typically administered in a feed matrix where it exerts its effects on phytate degradation.

Pregnancy

There is limited data on the use of phytase during pregnancy. Consultation with a healthcare provider is advised.

Breast-feeding

Limited information is available regarding the use of phytase while breastfeeding. Consultation with a healthcare provider is recommended.

Storage

Store in a cool, dry place away from direct sunlight. Keep out of reach of children.

Indications

• HIV/AIDS
• Cancer
• Chronic pancreatitis
• Certain inflammatory diseases

Dosage

Children: Refer to the BNF for Children for specific paediatric dosing information regarding protease inhibitors.

Adults: Refer to the BNF for specific dosage recommendations for protease inhibitors based on the particular drug and condition being treated.

Mechanism of action

Proteases function by hydrolyzing the peptide bonds that link amino acids in proteins. This process is essential for the activation of many proteins and for the degradation of misfolded or damaged proteins. In antiretroviral therapy, protease inhibitors block the action of viral proteases, preventing the maturation of viral particles and thereby inhibiting viral replication.

Pharmacodynamics

Proteases exhibit a variety of pharmacodynamic effects depending on their specific type and target. For instance, HIV protease inhibitors prevent the cleavage of viral polyproteins, which is essential for the production of infectious viral particles. The inhibition of proteolytic activity can lead to accumulation of unprocessed protein precursors, ultimately reducing the viral load in patients with HIV.

Pharmacokinetics

The pharmacokinetic profile of proteases varies widely among different classes. Generally, they are absorbed following oral administration, but the extent of absorption can be affected by food intake. Many protease inhibitors undergo extensive hepatic metabolism, particularly via the cytochrome P450 enzyme system. The elimination half-life can range from several hours to days, depending on the specific protease. Renal excretion plays a significant role in the clearance of some proteases, while others may be predominantly excreted in the feces.

Pregnancy

Refer to specific product guidelines as data may vary.

Breast-feeding

Refer to specific product guidelines as data may vary.

Storage

Mechanism of action

Xylanase acts by cleaving the β-1,4-glycosidic bonds in xylan, leading to the depolymerization of xylan into shorter xylooligosaccharides and xylose. This enzymatic reaction enhances the digestibility of plant materials, allowing for better nutrient absorption in animals and improved processing in food applications.

Pharmacodynamics

The pharmacodynamics of xylanase involves its ability to improve the digestibility of feed by breaking down complex carbohydrates in the gastrointestinal tract. This action can lead to enhanced nutrient availability, improved feed efficiency, and better overall growth performance in livestock. Additionally, xylanase can contribute to reducing the viscosity of digesta, which may improve gut health and nutrient absorption.

Pharmacokinetics

Xylanase is not typically absorbed into the systemic circulation as it acts locally within the gastrointestinal tract. Its activity is dependent on the pH and temperature of the environment, with optimal activity usually occurring in the neutral to slightly alkaline pH range. The enzyme is generally inactivated by extreme conditions, such as high temperatures or acidic pH, and is excreted in the feces after its action in the gut.

Pregnancy

There is insufficient data on the safety of xylanase in pregnancy. It is recommended to use caution and consult a healthcare provider before use.

Breast-feeding

There is limited information on the excretion of xylanase in human milk. It is advised to consult a healthcare provider before use during breastfeeding.

Storage
