Apparent efficacy (τ) estimates for etorphine, oxycodone and morphine
The efficacy (τ) for each was determined using the irreversible alkylation method. The values for τ derived by fitting the data from Fig 3 to the operational model of drug agonism (Black and Leff, 1983) as described by Zernig et al. (1996); see methods for complete description of fitting methods.
