LACTATION SECTION.


8.2 Lactation. Risk SummaryThere are no data regarding the presence of sincalide in human or animal milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for Sincalide for Injection and any potential adverse effect on the breastfed infant from Sincalide for Injection or from the underlying condition.

ADVERSE REACTIONS SECTION.


6 ADVERSE REACTIONS. The following adverse reactions associated with the use of Sincalide for Injection were identified in clinical trials or postmarketing reports. Because these reactions were reported voluntarily from population of uncertain size, it is not always possible to estimate their frequency, reliably, or to establish causal relationship to drug exposure.The most frequent adverse reactions (20% or greater) are gastrointestinal: abdominal discomfort or pain, and nausea; these may not necessarily indicate an abnormality of the biliary tract unless there is other clinical or radiologic evidence of disease.Less common adverse reactions include:Hypersensitivity reactions: anaphylaxis and anaphylactic shock, hypotension, throat tightness, bradycardia, shortness of breath, nausea, abdominal cramping, diaphoresis, hives, rash, itching; and numbness of face, lips and eyes [see Contraindications (4), (5.1)].Neurological reactions: seizures, headache.Vasovagal reactions: dizziness, loss of consciousness, nausea, diaphoresis, syncope and hypotension (generally self-limiting).Other: nausea, vomiting, flushing, hypertension, urge to defecate, diarrhea, sneezing.. Most common adverse reactions (>=20%) are: abdominal discomfort or pain, and nausea.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Long-term studies in animals have not been performed to evaluate carcinogenic or mutagenic potential, or possible impairment of fertility in males or females.

CLINICAL PHARMACOLOGY SECTION.


12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. When injected intravenously, sincalide stimulates gallbladder contraction and reduction in size. The evacuation of bile that results is similar to that which occurs physiologically in response to endogenous cholecystokinin. Sincalide also stimulates pancreatic secretion and intestinal motility causing pyloric contraction and slows gastric emptying.Concurrent administration of sincalide with secretin increases both the volume of pancreatic secretion and the out-put of bicarbonate and enzymes. This combined effect of secretin and sincalide permits the assessment of specific pancreatic function through measurement and analysis of the duodenal aspirate.. 12.2 Pharmacodynamics. Following an intravenous (bolus) injection of 0.02 mcg/kg of sincalide, maximal contraction of the gallbladder occurred in to 15 minutes. Sincalide reduced gallbladder radiographic size by at least 40%, which is generally considered satisfactory contraction.

CONTRAINDICATIONS SECTION.

OVERDOSAGE SECTION.


10 OVERDOSAGE. In the event of an overdose, symptoms related to vagal stimulation, such as gastrointestinal symptoms (abdominal cramps, nausea, vomiting and diarrhea), hypotension with dizziness or fainting may occur. Overdosage symptoms should be treated symptomatically and should be of short duration.A single bolus intravenous injection of 0.05 mcg/kg (approximately to times the human dose of 0.02 mcg/kg), sincalide caused hypotension and bradycardia in dogs. In addition, higher doses injected intravenously once or repeatedly in dogs caused syncope and ECG changes (approximately times the human dose of 0.02 mcg/kg). These effects were attributed to sincalide-induced vagal stimulation in that all were prevented by pretreatment with atropine or bilateral vagotomy.

PREGNANCY SECTION.


8.1 Pregnancy. Risk SummaryBased on limited human data and mechanism of action, sincalide may cause preterm labor or spontaneous abortion [see Warnings and Precautions (5.4)]. Available data with Sincalide for Injection are insufficient to establish drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. In animal embryo-fetal development studies in which sincalide was administered to hamsters and rats during the period of organogenesis, no effects were seen at doses comparable to the maximum recommended clinical dose on mg/kg basis. However, in prenatal development study in which rats were administered sincalide during organogenesis through parturition, decreased weight gain and developmental delays were observed at dose 122 times higher than the maximum recommended human dose based on body surface area.The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is to 4% and 15 to 20%, respectively.. Data. Animal DataThere were no effects on embryo-fetal development in hamsters when sincalide was administered subcutaneously at 250 or 750 ng/kg during organogenesis (Gestation Days to 13) at doses up to 0.8 times the maximum recommended dose of 120 ng/kg on body surface area basis. No effects on embryo-fetal development were observed in Sprague-Dawley rats at subcutaneous doses of 250, 450, or 750 ng/kg from Gestation Days to16, representing 1.0 time the maximum recommended human dose on body surface area basis. In separate study at higher dose of 90 mcg/kg administered subcutaneously to CFY rats from Gestation Day 10 through parturition (representing 122 times the maximum recommended human dose on body surface area basis), offspring showed decreased growth, behavioral changes, and developmental delays.
