5-hydroxytryptophan and Serotonin Syndrome

5-hydroxytryptophan has been researched along with Serotonin Syndrome in 19 studies

5-Hydroxytryptophan: The immediate precursor in the biosynthesis of SEROTONIN from tryptophan. It is used as an antiepileptic and antidepressant.
5-hydroxytryptophan : A tryptophan derivative that is tryptophan substituted by a hydroxy group at position 5.

Serotonin Syndrome: An adverse drug interaction characterized by altered mental status, autonomic dysfunction, and neuromuscular abnormalities. It is most frequently caused by use of both serotonin reuptake inhibitors and monoamine oxidase inhibitors, leading to excess serotonin availability in the CNS at the serotonin 1A receptor.

( Jennifer, H; Karyn, B; Mariana, P, 2017)
"Pre-treatment with diazepam, 10 and 20mg/kg, and chlormethiazole, 50 and 100mg/kg, attenuated the development of hyperthermia."5.32Diazepam and chlormethiazole attenuate the development of hyperthermia in an animal model of the serotonin syndrome. ( Kato, S; Nisijima, K; Shioda, K; Takano, K; Yoshino, T, 2003)

" The 5-HT1A antagonist WAY 100635 decreased 5-HTP-induced hypothermia in SERT+/+ and +/- mice with no effect in SERT-/- mice, whereas the 5-HT7 antagonist SB 269970 decreased this exaggerated response in SERT-/- mice only."3.74Neurochemical, behavioral, and physiological effects of pharmacologically enhanced serotonin levels in serotonin transporter (SERT)-deficient mice. ( Fox, MA; French, HT; Huang, SJ; Jensen, CL; Murphy, DL; Stein, AR; Tolliver, TJ, 2008)
"Serotonin syndrome is an increasingly common toxic syndrome in veterinary medicine with the availability of over-the-counter medications that alter serotonin metabolism."1.46Serotonin Syndrome from 5-Hydroxytryptophan Supplement Ingestion in a 9-Month-Old Labrador Retriever. ( Jennifer, H; Karyn, B; Mariana, P, 2017)
" However, the neural mechanism by which extracellular 5-HT is elevated to a toxic level for the syndrome remains to be determined."1.35Assessment of 5-hydroxytryptamine efflux in rat brain during a mild, moderate and severe serotonin-toxicity syndrome. ( Huang, X; Krishnamoorthy, S; Ma, Z; Tao, R; Vukovich, NP; Zhang, G, 2009)
"Pre-treatment with diazepam, 10 and 20mg/kg, and chlormethiazole, 50 and 100mg/kg, attenuated the development of hyperthermia."1.32Diazepam and chlormethiazole attenuate the development of hyperthermia in an animal model of the serotonin syndrome. ( Kato, S; Nisijima, K; Shioda, K; Takano, K; Yoshino, T, 2003)
"Pretreatment with risperidone (0."1.32Memantine, an NMDA antagonist, prevents the development of hyperthermia in an animal model for serotonin syndrome. ( Kato, S; Nisijima, K; Shioda, K; Takano, K; Yoshino, T, 2004)
"Pretreatment with propranolol (10 mg/kg), a 5-HT(1A) receptor antagonist as well as a beta-blocker, and dantrolene (20 mg/kg), a peripheral muscle relaxant, did not prevent the death of the animals, even though these two drugs suppressed the increase in rectal temperature to some extent."1.31Potent serotonin (5-HT)(2A) receptor antagonists completely prevent the development of hyperthermia in an animal model of the 5-HT syndrome. ( Katoh, S; Nisijima, K; Yoshino, T; Yui, K, 2001)
