Release date- 29082019 - SAN DIEGO - La Jolla Pharmaceutical Company (Nasdaq: LJPC), a leader in the discovery, development and commercialization of innovative therapies intended to significantly improve outcomes in patients suffering from life-threatening diseases, today announced that the European Commission (EC) has approved GIAPREZA (angiotensin II) for the treatment of refractory hypotension in adults with septic or other distributive shock who remain hypotensive despite adequate volume restitution and application of catecholamines and other available vasopressor therapies.
Catecholamines act as both neurotransmitters and hormones produced by the sympathetic branch of the autonomic nervous system (ANS).
[1-4] Anxiety in the pre-operative period may cause an elevation in the level of endogenous catecholamines, cortisol, and natural killer lymphocytes, which may lead to delayed wound healing and recovery.
Hg binding to co-enzyme S-adenosyl methionine results in inactivation of catechol-O-methyltransferase required for degradation of catecholamines (7).
Sensitivity to the catecholamines is enhanced by TCAs, which may result in arrhythmias and hypertension when indirect- or direct-acting sympathomimetic drugs are used.[1] Similarly, anesthetics known to increase endogenous circulating catecholamines such as ketamine-, pancuronium-, and epinephrine-containing solution should be avoided.[4] Vasopressin is a nonapeptide hormone synthesized in the magnocellular neurons of the paraventricular and supraoptic nuclei of the hypothalamus.[5] The vasoconstrictive effect of vasopressin is independent of catecholamine and angiotensin receptors.
Pre-operative diagnostic tests include 24-hour urine or plasma fractionated catecholamines and metanephrines.
This product is the generic version of Endo International plc's original Vasostrict formulation, which is indicated to increase blood pressure in adults with vasodilatory shock (e.g., post-cardiotomy or sepsis) who remain hypotensive despite fluids and catecholamines.
Within the pancreas, catecholamines drive production of molecules that stimulate nerve growth around tumors.
Abdominal MRI and elevated urinary methylated metabolites of catecholamines (Metanephrine = 3.2 [micro]mol / 24h (normal range (NR) 0.2 to 1), Normetanephrine = 47.5 [micro]mol / 24 h (NR: 0.4 to 2.1)) confirmed the diagnosis of catecholamine-secreting retroperitoneal PG.
Pheochromocytomas are usually functional and secrete catecholamines. In rare cases they have been shown to also secrete interleukins, calcitonin, and testosterone [2].
