Vasopressin is used to manage anti-diuretic hormone deficiency. It has off-label uses and is used in the treatment of gastrointestinal bleeding, ventricular tachycardia and ventricular defibrillation. Vasopressin is used to treat diabetes insipidus related to low levels of antidiuretic hormone. It is available as Pressyn.
Antihypotensive. A vasopressor is a drug or other agent which causes the constriction of blood vessels to increase systemic vascular resistance. This is different from inotopes which increase the force of contraction of heart muscle. Some substances do both (e.g. dopamine, dobutamine) .
Vasopressin. Human vasopressin, also called antidiuretic hormone (ADH), arginine vasopressin (AVP) or argipressin, [5] is a hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus, [6] and is converted to AVP. It then travels down the axon terminating in the posterior pituitary, and is released from vesicles ...
Midodrine, sold under the brand names ProAmatine and Orvaten among others, is a vasopressor or antihypotensive medication used to treat orthostatic hypotension (low blood pressure when standing) and urinary incontinence. [3][5][1] It is taken by mouth. [3][1] Side effects of midodrine include hypertension (high blood pressure), paresthesia ...
Vasopressin receptor antagonist. A vasopressin receptor antagonist (VRA) is an agent that interferes with action at the vasopressin receptors. Most commonly VRAs are used in the treatment of hyponatremia, especially in patients with congestive heart failure, liver cirrhosis or SIADH. [1]
Cardiotonic agents, also known as cardiac inotropes or stimulants, have a positive impact on the myocardium (muscular layer of the heart) by enhancing its contractility. Unlike general inotropes, these agents exhibit a higher level of specificity as they selectively target the myocardium. They can be categorised into four distinct groups based ...
Neurology. Neurogenic shock is a distributive type of shock resulting in hypotension (low blood pressure), often with bradycardia (slowed heart rate), caused by disruption of autonomic nervous system pathways. [1] It can occur after damage to the central nervous system, such as spinal cord injury and traumatic brain injury.
Vasodilatory shock, vasogenic shock, or vasoplegic shock is a medical emergency belonging to shock along with cardiogenic shock, septic shock, allergen-induced shock and hypovolemic shock. When the blood vessels suddenly relax, it results in vasodilation. In vasodilatory shock, the blood vessels are too relaxed leading to extreme vasodilation ...
