Research ArticleOpen accessIn the abstractAmphetamine Stimulates Protein Kinase and Calcium Influx to Increase Corticosterone and Aldosterone Secretion from Male Rat Adrenal CellsLing-Ling Chang, Wan-Song Alfred Wun, Cai-Yun Jian, Paulus S. WangAmphetamine is a potent central nervous system stimulant. Clinical trials have demonstrated that in healthy adults, low (therapeutic) doses of amphetamine can improve i.e., cognition, memory, attention behavior. An amphetamine overdose can affect cardiovascular, central nervous system, musculoskeletal, respiratory, urinary, or sexual function. Furthermore, amphetamine can activate the hypothalamic-pituitary-adrenal axis to increase glucocorticoids and mineralocorticoids released from adrenal. The object … …American Journal of Pharmacology and Toxicology, Vol. 16, Issue 1 · 10 Mar 2021 · 7,875 accessesView PDFCite
