CaSR, or Calcium-Sensing Receptor, activators are a group of pharmaceuticals that target the CaSR receptor. This receptor plays a crucial role in maintaining calcium balance in the body. Activating the CaSR can regulate calcium levels, benefiting individuals with conditions like hyperparathyroidism. By stimulating the CaSR, these drugs help to decrease parathyroid hormone levels and reduce the risk of complications related to excessive calcium in the bloodstream. CaSR activators are a prime example of how targeted therapies can effectively manage disorders related to mineral metabolism.
