Regional haemodynamic effects of human alpha- and beta-calcitonin gene-related peptide in conscious Wistar rats.

abstract：:Opioid drugs such as morphine and meperidine are widely used in clinical pain management, although they can cause some adverse effects. A number of studies indicate that N-methyl-D-aspartate (NMDA) receptors may play a role in the mechanism of morphine analgesia, tolerance and dependence. Being an antitussive with NMD...
