Note that decre- ments in DSST score, and increases in EEG betaamplitude, werevery similar between trials B and C, whereas ef- fects were significantly enhanced during trials D and E. Mean clearance of triazolam during trials B and C was macokinetics, pharmacodynamics, and drug metabolism nearly identical (413 and 416 mL/min, respectively); that may be usefully applied to the evaluation of drug interac- is, coadministration of azithromycin had no effect on the tions.

The pharmacodynamic data indicated that the benzodi- azepine agonist effects of triazolam plus placebo (trial B), and of triazolam plus azithromycin (trial C) were similar to each other, and greater than the effects of placebo plus pla- cebo (trial A). However, coadministration of triazolam with erythromycin (trial D) or with clarithromycin (trial E) aug- mented the pharmacodynamic effects of triazolam when compared to trials B or C. The outcome was similar whether based on subjective measures, a semi-objective measure (the Digit-Symbol Substitution Test, DSST), or the fully objec- tive measure (the EEG) (Fig. Kinetic-dynamic mod- eling indicated that the increase in benzodiazepine agonist effects of triazolam caused by coadministration of erythro- mycin or clarithromycin was fully consistent with the in- crease in triazolam plasma concentrations (Fig. COMMENT Pharmacokinetic drug interactions in clinical psychophar- macology are assuming increasing importance as polyphar- macy becomes more common, and more drugs with en- FIGURE 38.

Table 33 summarises the differences in total health-care costs after adjustment for covariates for the entire patient cohort and individual risk groups 60 ml liv 52 mastercard. The difference between the total cost in the control phase and intervention phase was found to be statistically significant (p < 0 cheap liv 52 100 ml free shipping. Differences were no longer statistically significant in risk groups 3 and 4. Health-care costs per patient in the intervention phase were generally slightly higher, but £3 lower in primary care and £0. The main cost drivers were found to be inpatient stays (elective and emergency) and GP visits.

Including all primary and secondary care costs and after covariate adjustment, the total cost difference between the control and intervention phase shows an increase of £75. Cost-effectiveness analysis All costs were annualised to account for the difference in the duration of the control and intervention phases. Base-case analysis showed a small difference in total health-care costs between the control and intervention phases (see Table 25). This was mainly attributable to the relatively small implementation cost of PRISM per patient and the marginal cost increases per patient during the intervention phase. The clinical effectiveness analysis found an increase in the number of emergency admissions from 0.
