§ Acute intermittent porphyria—precipitated by barbiturates is due to genetic defect in repression of porphyrin synthesis.
§ Tolerance occurs to analgesic and euphoric action of morphine, although not as much to its constipating and miotic actions.
Following numerous dosing, bioavailability could be estimated by measuring unchanged drug recovered from urine over a 24-hour interval beneath regular-state problems.
