Professor Riccardi and her collaborators are now seeking funding to determine the efficacy of calcilytic drugs in treating asthmas that are especially difficult to treat, particularly steroid-resistant and influenza-exacerbated asthma, and to test these drugs in patients with asthma. Recently we have shown that they can suppress airway hyperresponsiveness (AHR) and inflammation in asthma models, providing a potential for a novel asthma treatment strategy 1. 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. The study was part-funded by Asthma UK, the Cardiff Partnership Fund and a BBSRC 'Sparking Impact' award. A medicine to block the activation of CaSR could, potentially, prevent asthma attacks from occurring, thereby preventing the need for asthma rescue medicine. This post from The Telegraph reports news of asthma … COVID-19 is an emerging, rapidly evolving situation. Asthma is a medical condition that causes breathing difficulties. Eur J Clin Pharmacol. 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.
