Histamine Release Physiology at Rosario Maynard blog

Histamine Release Physiology. Histamine release caused by reactions to drug product and/or excipients/vehicles is a phenomenon observed in both toxicology and pharmacology. Histamine release is enhanced under extreme conditions such as dehydration or hypoglycemia or by a variety of stressors. In humans, histamine is a molecular transducer of physical activity responses, and antihistamines modify > 25% of the genes responding to exercise. Histamine release can occur with administration of certain opioids (particularly morphine and meperidine administered iv), resulting in sequelae. H4 receptors are present in the bone. Histamine has predominantly inhibitory effects on the release of gh and tsh but is a potent stimulus for avp and oxytocin release. H3 receptors are essential modulators of histamine release from mast cells and cerebral neurons.
