Switch medication from maprotiline to hypericum.[1] [2]
Stop maprotiline - Before day 1: gradually reduce dosage of maprotiline to a maximum of 75 mg/day.
- Day 1: reduce dosage of maprotiline to 50 mg/day.
- Day 7: reduce dosage of maprotiline to 25 mg/day.
- Day 14: stop dosage of maprotiline.
Start hypericum- Day 14-28: a wash-out period of 2 weeks is necessary.
- Day 28: start administration of hypericum.
More information- Hypericum induces enzymes of the CYP P-450 type and P-gp type.
- Hypericum might have MAO-inhibiting and/or COMT-inhibiting properties.
- Many studies reported that hypericin is the main source of pharmacological effects of hypericum. However the IC50 of hypericin to inhibit MAO A and MAO B is 100- to 1000-fold higher than accessible Cmax values of hypericin after oral administration of hypericum.[3]
