Metformin is a pleiotropic drug, with extensive off-target activity beyond its antidiabetic effect. Much of this has been attributed to its action on AMPK, although other mechanisms have been proposed. [223] [224] Metformin has been studied for its effects on multiple other conditions, including: Non-alcoholic fatty liver disease [225] [226] [227]
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. [6]
Diabetes medications have four main mechanisms of action: [citation needed] Insulin sensitization: Increased sensitivity of insulin receptors on cells leading to decreased insulin resistance, and higher effects of insulin on blood glucose levels. Stimulation of beta cells: This stimulation increases insulin secretion from beta cells of pancreas.
Vasopressin is released into the brain in a circadian rhythm by neurons of the suprachiasmatic nucleus. [21] Vasopressin released from posterior pituitary is associated with nausea. [22] Recent evidence suggests that vasopressin may have analgesic effects. The analgesia effects of vasopressin were found to be dependent on both stress and sex. [23]
Vasopressin receptor antagonists (VRAs) are drugs that block vasopressin receptors. Most commonly VRAs are used to treat hyponatremia caused by syndrome of inappropriate antidiuretic hormone secretion (SIADH), congestive heart failure (CHF) and cirrhosis. [2] Somatostatin is a competitive inhibitor. [5]
2. Alleviates Hunger. Metformin improves how well your cells respond to insulin. This helps regulate your blood sugar levels and manage spikes in insulin that can trigger hunger and food cravings.
The "vaptan" drugs act by directly blocking the action of vasopressin at its receptors (V 1A, V 1B and V 2).These receptors have a variety of functions, with the V 1A and V 2 receptors are expressed peripherally and involved in the modulation of blood pressure and kidney function respectively, while the V 1A and V 1B receptors are expressed in the central nervous system.
Desmopressin (1-deamino-8-D-arginine vasopressin) is a synthetic form of the normal human hormone arginine vasopressin (the antidiuretic hormone, or ADH), a peptide containing nine amino acids. Compared to vasopressin, desmopressin's first amino acid has been deaminated , and the arginine at the eighth position is in the dextro rather than the ...
