Sacrosidase

INDICATIONS AND USAGE Sucraid ® (sacrosidase) Oral Solution is indicated for the treatment of sucrase deficiency, which is part of congenital sucrase-isomaltase deficiency (CSID), in adult and pediatric patients 5 months of age and older.

CLINICAL PHARMACOLOGY Congenital sucrase-isomaltase deficiency (CSID) is a chronic, autosomal recessive, inherited, phenotypically heterogeneous disease with very variable enzyme activity. CSID is usually characterized by a complete or almost complete lack of endogenous sucrase activity, a very marked reduction in isomaltase activity, and a moderate decrease in maltase activity. Sucrase is naturally produced in the brush border of the small intestine, primarily the distal duodenum and jejunum. Sucrase hydrolyzes the disaccharide sucrose into its component monosaccharides, glucose and fructose. Isomaltase breaks down disaccharides from starch into simple sugars. Sucraid does not contain isomaltase. In the absence of endogenous human sucrase, as in CSID, sucrose is not metabolized. Unhydrolyzed sucrose and starch are not absorbed from the intestine and their presence in the intestinal lumen may lead to osmotic retention of water. This may result in loose stools. Unabsorbed sucrose in the colon is fermented by bacterial flora to produce increased amounts of hydrogen, methane, and water. As a consequence, excessive gas, bloating, abdominal cramps, diarrhea, nausea, and vomiting may occur. Chronic malabsorption of disaccharides may result in malnutrition. Undiagnosed/untreated CSID patients often fail to thrive and fall behind in their expected growth and development curves. Previously, the treatment of CSID has required the continual use of a strict sucrose-free diet.

DOSAGE AND ADMINISTRATION Important Administration Information Administer Sucraid with each meal or snack. Mix Sucraid with cold or room temperature water, milk or infant formula prior to administration. Administration of Sucraid in liquids other than water, milk, or infant formula has not been studied and is not recommended. Do not mix or consume Sucraid with fruit juice. Do not warm or heat the water, milk, or infant formula before or after addition of Sucraid. Administer half of the dose at the beginning of the meal or snack and the other half of the dose during the meal or snack. Recommended Dosage The recommended dosage is: Patients weighing 15 kg and less: 8,500 International Units (1 mL) administered orally with each meal or snack. Patients weighing more than 15 kg: 17,000 International Units (2 mL) administered orally with each meal or snack. Preparation and Administration Instructions for Patients Weighing 15 kg or Less Multiple-Dose Bottle: Using the measuring scoop provided, add 1 scoop of Sucraid (1 mL) to 60 mL of cold or room temperature water, milk, or infant formula. Stir to mix well. Administer half of the mixed Sucraid solution (30 mL) at the beginning of the meal or snack and the other half of the mixed solution (30 mL) during the meal or snack. Do not save any of the mixed Sucraid solution for later use. Rinse the measuring scoop with water. Single-Use Container: Empty the entire contents of the single-use container (2 mL) in 120 mL of cold or room temperature water, milk, or infant formula. Stir to mix well. Divide the mixed Sucraid solution into two separate 60 mL portions. The first portion (60 mL) is for immediate use. • Administer half of the first portion (30 mL) of the mixed Sucraid solution at the beginning of the meal or snack and the other half of the first portion (30 mL) of the mixed Sucraid solution during the meal or snack. Store the second portion of the mixed Sucraid solution (60 mL) at 2°C to 8°C (36°F to 46°F) for up to 24 hours for administration with the next meal or snack. • Discard the mixed Sucraid solution if not used within 24 hours. Preparation and Administration Instructions for Patients Weighing More than 15 kg Multiple-Dose Bottle: Using the measuring scoop provided, add 2 scoops of Sucraid (2 mL) to 120 mL of cold or room temperature water, milk, or infant formula. Stir to mix well. Administer half of the mixed Sucraid solution (60 mL) at the beginning of the meal or snack and the other half of the mixed Sucraid solution (60 mL) during the meal or snack. Do not save any of the mixed Sucraid solution for later use. Rinse the measuring scoop with water. Single-Use Container: Empty the entire contents of the single-use container (2 mL) in 120 mL of cold or room temperature water, milk, or infant formula. Stir to mix well. Administer half of the mixed Sucraid solution (60 mL) at the beginning of the meal or snack and the other half of the mixed solution during the meal or snack (60 mL). Do not save any of the mixed Sucraid solution for later use.

ADVERSE REACTIONS The following adverse reactions associated with the use of sacrosidase were identified in clinical studies or postmarketing reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. In clinical studies of up to 54 months duration, a total of 52 patients were treated with Sucraid. The reported adverse reactions (number of patients) were as follows: abdominal pain (4), vomiting (3), nausea (2), diarrhea (2), constipation (2), insomnia (1), headache (1), nervousness (1), and dehydration (1). Hypersensitivity reactions (wheezing, rash, and pruritis) have been reported (see WARNINGS).

WARNINGS Severe Hypersensitivity Reactions Severe hypersensitivity reactions, including wheezing, rash, and pruritis, have been reported with administration of Sucraid. Sucraid contains papain, which is associated with hypersensitivity reactions (see DESCRIPTION). A pediatric patient in the clinical trials experienced a hypersensitivity reaction of severe wheezing that required hospitalization. Postmarketing cases of cutaneous hypersensitivity reactions have also been reported. Instruct patients or caregivers to stop Sucraid and seek medical attention if symptoms suggestive of a hypersensitivity reaction occur. Sucraid is contraindicated in patients who have had a known hypersensitivity reaction (see CONTRAINDICATIONS).

CONTRAINDICATIONS Sucraid is contraindicated in patients known to be hypersensitive to yeast, yeast products, glycerin (glycerol), or papain (see WARNINGS).
