Secretin porcine stimulates pancreatic and gastric secretions to aid in the diagnosis of pancreatic exocrine dysfunction and the diagnosis of gastrinoma. Porcine Secretin for Injection administered intravenously stimulates gastrin release in patients with gastrinoma whereas only small changes in serum gastrin concentrations occur in healthy subjects and patients with peptic ulcer disease. The primary action of secretin is to stimulate pancreatic ductal cells to secrete pancreas fluid in large volumes that contain bicarbonate. Secretin is a hormone that is normally released from the duodenum upon exposure of the proximal intestinal lumen to gastric acid, fatty acids, and amino acids. Secretin is released from enterochromaffin cells in the intestinal mucosa. Secretin receptors have been identified in the pancreas, stomach, liver, colon, brain and other tissues. When secretin binds to secretin receptors on pancreatic duct cells it opens cystic fibrosis transmembrane conductance regulator (CFTR) channels, leading to secretion of bicarbonate-rich pancreatic fluid. Secretin may also work through vagal-vagal neural pathways since stimulation of the efferent vagus nerve stimulates bicarbonate secretion and atropine blocks secretin-stimulated pancreatic secretion.

Bivalirudin is a synthetic 20 amino acid peptide rationally designed based on structural studies of hirudin, a naturally occurring anticoagulant. Bivalirudin is sold under the brand name Angiomax and is indicated for use as an anticoagulant in patients with unstable angina undergoing percutaneous transluminal coronary angioplasty (PTCA). It is intended for use with aspirin and has been studied only in patients receiving concomitant aspirin. Bivalirudin directly inhibits thrombin by binding simultaneously to its active catalytic site and its substrate recognition site.

Triptorelin is a synthetic decapeptide agonist analog of luteinizing hormone releasing hormone (LHRH). It works by decreasing the production of certain hormones, which reduces testosterone levels in the body. Animal studies comparing triptorelin to native GnRH found that triptorelin had 13 fold higher releasing activity for luteinizing hormone, and 21-fold higher releasing activity for follicle-stimulating hormone. Triptorelin is indicated for the palliative treatment of advanced prostate cancer.

Insulin aspart, a human insulin analogue, is a rapid-acting, parenteral blood glucose-lowering agent. Insulin aspart was marketed under the brand name NovoLog for the treatment of adult patients with diabetes mellitus, for the control of hyperglycemia. The primary activity of the drug is the regulation of glucose metabolism. Insulin aspart binds to the insulin receptors on muscle and fat cells and lower blood glucose by facilitating the cellular uptake of glucose and simultaneously inhibiting the output of glucose from the liver. This drug has an off-label treatment for gestational diabetes (temporary diabetes caused by diabetes).

Insulin glargine, a long-acting form of insulin, was marketed under the brand name LANTUS. Lantus is indicated for the treatment of adult and pediatric patients with type 1 diabetes mellitus or adult patients with type 2 diabetes mellitus who require basal (long-acting) insulin for the control of hyperglycemia. The primary activity of insulin glargine is regulation of glucose metabolism. It lowers blood glucose levels by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. The off-label use of insulin glargine is the treatment type 2 diabetes in children and the treatment of gestational diabetes.

Corticorelin ovine is an analogue of the naturally occurring human corticotropin-releasing hormone (hCRH) peptide. Corticorelin ovine is a potent stimulator of adrenocorticotropic hormone (ACTH) release from the anterior pituitary. ACTH stimulates cortisol production from the adrenal cortex. Corticorelin ovine was marketed under the brand name ACTHREL for use in differentiating pituitary and ectopic production of ACTH in patients with ACTH-dependent Cushing’s syndrome.

Insulin lispro is a rapid-acting form of insulin used for the treatment of hyperglycemia caused by Type 1 and Type 2 Diabetes. Chemically, insulin lispro is Lys(B28), Pro(B29) human insulin analog, created when the amino acids at positions 28 and 29 on the insulin B-chain are reversed. Insulin lispro is synthesized in a special non-pathogenic laboratory strain of Escherichia coli bacteria that has been genetically altered by the addition of the gene for insulin lispro. Regulation of glucose metabolism is the primary activity of insulins and insulin analogs, including insulin lispro products. Insulins lower blood glucose by stimulating peripheral glucose uptake by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulins inhibit lipolysis and proteolysis, and enhance protein synthesis. Insulin lispro begins to exert its effects within 15 minutes of subcutaneous administration, while peak levels occur 30 to 90 minutes after administration. Due to its duration of action of around 5 hours, Humalog is considered "bolus insulin" as it provides high levels of insulin in a short period of time to mimic the release of endogenous insulin from the pancreas after meals. Bolus insulin is often combined with once daily, long-acting "basal insulin" to provide low concentrations of background insulin that can keep blood sugar stable between meals or overnight. Use of basal and bolus insulin together is intended to mimic the pancreas' production of endogenous insulin, with a goal of avoiding any periods of hypoglycemia.

Teriparatide was manufactured under the brand name FORTEO. FORTEO contains recombinant human parathyroid hormone (1-34), [rhPTH(1-34)], which has an identical sequence to the 34 N-terminal amino acids (the biologically active region) of the 84-amino acid human parathyroid hormone, that regulates calcium and phosphate in the body. FORTEO is indicated for the treatment of postmenopausal women with severe osteoporosis who are at high risk of fracture or who have failed or are intolerant to previous osteoporosis therapy. In addition, Forteo is used for the treatment of osteoporosis associated with sustained systemic glucocorticoid therapy in men and women who are at increased risk for fracture. The biological actions of teriparatide is mediated through binding to specific high-affinity cell-surface receptors. Teriparatide is not expected to accumulate in bone or other tissues.

Human Insulin, also known as Regular Insulin, is a short-acting form of insulin used for the treatment of hyperglycemia caused by Type 1 and Type 2 Diabetes. Human insulin is produced by recombinant DNA technology and is identical to endogenously produced insulin. Insulin lowers blood glucose levels by stimulating peripheral glucose uptake by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis in adipocytes, inhibits proteolysis, and enhances protein synthesis. Human insulin begins to exert its effects within 30 minutes of subcutaneous administration, while peak levels occur 3-4 hours after administration. Due to its quick onset of action, human insulin is considered "bolus insulin" as it provides high levels of insulin in a short period of time to mimic the release of endogenous insulin from the pancreas after meals. Bolus insulin is often combined with once daily, long-acting "basal insulin" to provide low concentrations of background insulin that can keep blood sugar stable between meals or overnight. Use of basal and bolus insulin together is intended to mimic the pancreas' production of endogenous insulin, with a goal of avoiding any periods of hypoglycemia.

Calcitonin-salmon is a polypeptide hormone secreted by the parafollicular cells of the ultimobranchial gland of salmon fish. Calcitonin-salmon Nasal Spray is a polypeptide of 32 amino acids manufactured by recombinant DNA technology and is identical to calcitonin produced by salmon fish or chemical synthesis. Calcitonin acts primarily on bone, but direct renal effects and actions on the gastrointestinal tract are also recognized. Calcitonin-salmon appears to have actions essentially identical to calcitonins of mammalian origin, but its potency per mg is greater and it has a longer duration of action. The actions of calcitonin on bone and its role in normal human bone physiology are still not completely elucidated, although calcitonin receptors have been discovered in osteoclasts and osteoblasts. Single injections of calcitonin cause a marked transient inhibition of the ongoing bone resorptive process. With prolonged use, there is a persistent, smaller decrease in the rate of bone resorption. Histologically, this is associated with a decreased number of osteoclasts and an apparent decrease in their resorptive activity. In vitro studies have shown that calcitonin-salmon causes inhibition of osteoclast function with loss of the ruffled osteoclast border responsible for resorption of bone. Calcitonin-salmon Nasal Spray is indicated for the treatment of postmenopausal osteoporosis in females greater than 5 years postmenopause with low bone mass relative to healthy premenopausal females.
