Unlabelled: In healthy postmenopausal women, nasal salmon calcitonin blunted distal radius and tibia bone microstructure degradation.
Introduction: Nasal salmon calcitonin (NSC) has been reported to lower vertebral fracture risk by 33%, but to modestly increase spine areal bone mineral density (aBMD) by 1.5%.
8-(N-2-hydroxy-5-chlorobenzoyl)-amino-caprylic acid (5-CNAC), a compound lacking pharmacological activity enhances the absorption of salmon calcitonin, when co-administered. Disposition and biotransformation of 5-CNAC was studied in six healthy postmenopausal women following a single oral dose of 200mg (14)C-radiolabeled 5-CNAC (as disodium monohydrate salt). Blood, plasma, urine and feces collected over 7 days were analyzed for radioactivity.

Both must be administered as a daily subcutaneous (sc) injection. A new oral formulation of human PTH1-34 (PTH134) is being developed as a more convenient option for patients.

There are indications that estrogen-deficiency, as the post-menopausal state, accelerate the development of OA.
Findings: We investigated, which extracellular matrix (ECM) protein, proteases and different pro-inflammatory factors was up- or down-regulated in the knee joint tissue in response to estrogen-deficiency in rats induced by ovariectomy.
