Osmotherapy inhibits these channels. Vasopressin receptors activated by vasopressin are found on the basolateral membrane of the cells lining the collecting ducts of the kidneys. Aneurysmal subarachnoid hemorrhage(aSAH) results in hyponatremia which leads to water retention and antidiuretic hormone release causing increase in intracranial pressure and formation of cerebral edema. This can be prevented by administration of conivaptan, a safe FDA approved drug that treats euvolemic hyponatremia. Through the process of aquaresis, conivapten which is a vasopressin receptor antagonist improves serum sodium concentration while eliminating free water without having any negative effect on systolic blood pressure and pulse rate.

Serum sickness Serum sickness Serum sickness in humans is a reaction to proteins in antiserum derived from a non-human animal source, occurring 5–10 days after exposure. It is a type of hypersensitivity, specifically immune complex hypersensitivity (type III). The term serum sickness–like reaction (SSLR) is occasionally used to refer to similar illnesses that arise from the introduction of certain non-protein substances, such as penicillin. It was first characterized by Clemens von Pirquet and Béla Schick in 1906. When an antiserum is given, the human immune system can mistake the proteins present for harmful antigens. The body produces antibodies, which combine with these
