Study findings on pharmacology are outlined in reports from University of Texas, Health Science Center

A report, "Time-dependent decreases in apparent pA2 values for naltrexone studied in combination with morphine in rhesus monkeys," is newly published data in Psychopharmacology. According to a study from the United States, "One assumption of Schild analyses, which have been used extensively to characterize opioids in vitro and in vivo, is that the concentration of antagonist is at equilibrium; violation of this assumption would yield slopes of Schild plots that deviate from unity. For in vivo studies, the concentration of antagonist changes as it is eliminated; however, if studies are conducted at a time when the antagonist is maximally effective, the assumption of equilibrium is...
