0004). CYP2C9 and CYP2C19 genotypes do not influence methadone plasma levels. Lower peak and trough plasma levels of methadone and higher peak-to-trough ratios

If the peak is much higher than the trough (at least twice as high), it suggests that the patient is metabolizing their methadone quickly and

Why are Peak and Trough Levels Important? Ensuring Effectiveness: Adequate peak levels mean that the methadone dose is sufficient to prevent withdrawal

Peak-to-trough ratio of methadone and EDDP. Peak-to-trough concentration ratios of plasma methadone and EDDP were calculated from 34 patients with both trough and peak plasma samples collected. The results are shown in Table IV. The mean ratio was 1.79 (SD 0.56, range 1.00 3.97) for methadone and 1.78 (SD 0.75, range 0.62 3.64) for EDDP.

A peak level measures the highest amount of methadone in your blood. A trough level measures the lowest (daily) level of methadone in your blood.
