It is a serious global health problem affecting all age groups, with increasing prevalence in many developing countries, rising treatment costs, and a rising burden for patients and the community. Asthma is a disease in which the airways swell up and tighten, making it hard to catch your breath. Second-line controller therapy for persistent asthma uncontrolled on inhaled corticosteroids: the step 3 dilemma. This article elaborates evidence supporting the hypothesis that topically delivered, inhaled antagonists of the calcium-sensing receptor (CaSR) have the potential to meet these requirements, and the practicality of repurposing existing, small molecule CaSR antagonists (calcilytics) for this purpose. Inhaled corticosteroids as combination therapy with beta-adrenergic agonists in airways disease: present and future. Asthma afflicts more than 300 million people. Calcilytics were first developed for the treatment of osteoporosis around 15 years ago with the aim of strengthening deteriorating bone by targeting CaSR to induce the release of an anabolic hormone. “Our findings point to an entirely novel pathophysiological mechanism in asthma.

Background: Inhibitors of the extracellular calcium-sensing receptor (CaSR), termed calcilytics, were developed to evoke pulsatile changes in plasma parathyroid hormone (PTH) levels as a novel anti-osteoporotic treatment. Calcilytics are pharmaceutical drugs that act as antagonists at the calcium-sensing receptor (CaSR). Asthma; bronchial hyperresponsiveness; calcilytic; calcium sensing receptor; inflammation; therapy. To rule out other possible conditions — such as a respiratory infection or chronic obstructive pulmonary disease (COPD) — your doctor will do a physical exam and ask you questions about your signs and symptoms and about any other health problems.

But this latest breakthrough has provided researchers with the unique opportunity to re-purpose these drugs, potentially accelerating the time it takes for them to be approved for use asthma patients. Contemporary mainstay therapies (inhaled corticosteroids and bronchodilators), prescribed empirically, control symptoms resulting from airways obstruction tolerably well in many patients but it is less clear that they alter the natural history of progressive airways inflammation and remodeling resulting in severe, therapy-resistant obstruction in a significant minority (5-10%), causing lifelong symptoms and elevated risk of recurrent hospital admission and death. This increases the secretion of parathyroid hormone (PTH), which has a temporary anabolic effect on bone tissue, producing an increase in both bone volume and bone density due to increased bone deposition and resorption.
