A Study Comparing Oral Calcitonin to Nasal Spray Calcitonin in Postmenopausal Osteoporotic Women

2014-08-27 03:20:01 | BioPortfolio


The purpose of this study is to compare the effectiveness and tolerability of two medications, calcitonin nasal spray and a tablet containing calcitonin, in postmenopausal women with osteoporosis. Osteoporosis is the term used to describe a large group of diseases, which are characterized by loss of bone density, which makes the bones weaker. Osteoporosis often occurs in postmenopausal women.

Calcitonin is a hormone found in the human body. Together with other substances, it regulates the concentration of calcium in the blood and inhibits the natural resorption of bone. Both medications in this study contain salmon calcitonin (sCT), because this form of calcitonin is more active than human calcitonin when used as a medicine.

The calcitonin Nasal Spray used in this study is registered and available to doctors in United States for the treatment of osteoporosis. The medication being tested in this study is an oral tablet form of salmon calcitonin.

Medical and Biotech [MESH] Definitions

Cell surface proteins that bind calcitonin and trigger intracellular changes which influence the behavior of cells. Calcitonin receptors outside the nervous system mediate the role of calcitonin in calcium homeostasis. The role of calcitonin receptors in the brain is not well understood.

Calcitonin gene-related peptide. A 37-amino acid peptide derived from the calcitonin gene. It occurs as a result of alternative processing of mRNA from the calcitonin gene. The neuropeptide is widely distributed in neural tissue of the brain, gut, perivascular nerves, and other tissue. The peptide produces multiple biological effects and has both circulatory and neurotransmitter modes of action. In particular, it is a potent endogenous vasodilator.

Reduction of bone mass without alteration in the composition of bone, leading to fractures. Primary osteoporosis can be of two major types: postmenopausal osteoporosis (OSTEOPOROSIS, POSTMENOPAUSAL) and age-related or senile osteoporosis.

Cell surface proteins that bind calcitonin gene-related peptide (CGRP) with high affinity and trigger intracellular changes which influence the behavior of cells. CGRP receptors are present in both the central nervous system and the periphery and are not the same as calcitonin receptors.

A receptor activity-modifying protein that is a subunit of specific G-PROTEIN COUPLED RECEPTORS. The CALCITONIN GENE-RELATED PEPTIDE RECEPTOR is formed from a dimer of this protein and CALCITONIN RECEPTOR-LIKE PROTEIN, while an isoform of the ISLET AMYLOID POLYPEPTIDE RECEPTOR is formed from this protein dimerizing with the CALCITONIN RECEPTOR.
