Low molecular weight opioid peptide esters (OPE) could become a class of analgesics with different side effect profiles than current opiates. OPE may have sufficient plasma stability to cross the blood brain barrier (BBB), undergo ester hydrolysis and produce analgesia. OPE of dipeptides, tyr-pro and tyr-gly conjugated to ethanol have a structure similar to the anesthestic agent, etomidate. Bas...
Opiates suppress TSH in experimental animals but are reported to increase TSH in human subjects. We describe a patient in severe pain treated with morphine, whose previously normal TSH fell to a level usually associated with hyperthyroidism. After returning to a normal concentration, TSH again decreased with morphine administration. This suggests that, in contrast to the stimulation of TSH secr...
A rapid, sensitive, and specific method for the determination of opiates and cocaine and metabolites in urine, plasma, and blood was established. A one-step extraction followed by liquid chromatography-electrospray ionization tandem mass spectrometry operating in multiple reaction monitoring mode was used. Two chromatographic runs were performed, each in less than 6 min. The lower limit for acc...
