Clinical Summary

Peptides derived from proglucagon which is also the precursor of pancreatic GLUCAGON. Despite expression of proglucagon in multiple tissues, the major production site of glucagon-like peptides (GLPs) is the INTESTINAL L CELLS. GLPs include glucagon-like peptide 1, glucagon-like peptide 2, and the various truncated forms.

Therapeutic Applications

This medication is the same as your body's own glucagon, a natural substance that raises blood sugar by causing the body to release sugar stored in the liver. It is used to treat very low blood sugar (hypoglycemia) that may cause you to need help from others. Make sure a family member or caregiver knows where you keep this medication and how to use it before you need their help.

Clinical Summary

The physiologically active form of vitamin D. It is formed primarily in the kidney by enzymatic hydroxylation of 25-hydroxycholecalciferol (CALCIFEDIOL). Its production is stimulated by low blood calcium levels and parathyroid hormone. Calcitriol increases intestinal absorption of calcium and phosphorus, and in concert with parathyroid hormone increases bone resorption.

Therapeutic Applications

Calcitriol is a man-made active form of vitamin D. Most people get enough vitamin D from exposure to the sun and from fortified food products (such as dairy products, vitamins). Vitamin D helps control parathyroid hormone and the levels of certain minerals (such as calcium, phosphorus) that are needed for building and keeping strong bones. Before regular vitamin D can be used by the body, it needs to be changed to the active form by the liver and kidneys. Calcitriol is used in patients with kidney disease who can't make enough of the active form of Vitamin D. This medication is also used to prevent and treat certain types of calcium/phosphorus/parathyroid problems that can happen with long-term kidney dialysis or hypoparathyroidism. Calcitriol is usually used along with specific diet recommendations and sometimes other medications.

Therapeutic Applications

Cinacalcet is used to treat increased amounts of a certain hormone (parathyroid) in people with long-term kidney disease who are on dialysis. It is also used to treat increased amounts of calcium in people with an overactive parathyroid gland or in people with cancer of the parathyroid gland. Cinacalcet works by decreasing the amount of parathyroid hormone, calcium, and phosphorus in your body. Having the right amount of these substances in your body helps to prevent bone disease.

Clinical Summary

A polypeptide that consists of the 1-34 amino-acid fragment of human PARATHYROID HORMONE, the biologically active N-terminal region. The acetate form is given by intravenous infusion in the differential diagnosis of HYPOPARATHYROIDISM and PSEUDOHYPOPARATHYROIDISM. (Reynolds JEF(Ed): Martindale: The Extra Pharmacopoeia (electronic version). Micromedex, Inc, Englewood, CO, 1995)

Therapeutic Applications

Teriparatide is used to treat bone loss (osteoporosis) in people who have a high risk of getting fractures. It is similar to a natural hormone in your body (parathyroid hormone). It works by increasing bone mass and strength. This effect helps to decrease the risk of getting a fracture. This medication is not recommended for use in children or young adults whose bones are still growing.

Clinical Summary

Insulin that has been modified so that the B-chain contains a LYSINE at position 28 instead of a PROLINE and a PROLINE at position 29 instead of a LYSINE. It is used to manage BLOOD GLUCOSE levels in patients with TYPE 2 DIABETES.

Therapeutic Applications

Insulin lispro is used with a proper diet and exercise program to control high blood sugar in people with diabetes. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. Insulin lispro is a man-made product that is similar to human insulin. It replaces the insulin that your body would normally make. Insulin lispro starts working faster and lasts for a shorter time than regular insulin. It works by helping blood sugar (glucose) get into cells so your body can use it for energy. This medication is usually used with a medium- or long-acting insulin product. Insulin lispro may also be used with other oral diabetes medications (such as sulfonylureas like glyburide or glipizide).

Clinical Summary

The main glucocorticoid secreted by the ADRENAL CORTEX. Its synthetic counterpart is used, either as an injection or topically, in the treatment of inflammation, allergy, collagen diseases, asthma, adrenocortical deficiency, shock, and some neoplastic conditions.

Therapeutic Applications

Hydrocortisone is a man-made version of a natural substance (cortisol) made by the adrenal gland. This drug is used to treat low cortisol levels caused by diseases of the adrenal gland (such as Addison's disease, adrenocortical insufficiency). Hydrocortisone belongs to a class of drugs known as corticosteroids. Corticosteroids are needed in many ways for the body to function well. They are important for salt and water balance and keeping blood pressure normal.

Clinical Summary

The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in the THYROGLOBULIN. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.

Therapeutic Applications

Levothyroxine is used to treat an underactive thyroid (hypothyroidism). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery. Having enough thyroid hormone is important for maintaining normal mental and physical activity. In children, having enough thyroid hormone is important for normal mental and physical development. This medication is also used to treat other types of thyroid disorders (such as thyroid cancer). This medication should not be used to treat infertility unless it is caused by low thyroid hormone levels.

Clinical Summary

A thioureylene antithyroid agent that inhibits the formation of thyroid hormones by interfering with the incorporation of iodine into tyrosyl residues of thyroglobulin. This is done by interfering with the oxidation of iodide ion and iodotyrosyl groups through inhibition of the peroxidase enzyme.

Therapeutic Applications

Methimazole is used to treat overactive thyroid (hyperthyroidism). It works by stopping the thyroid gland from making too much thyroid hormone.
