WHICH 1ST GEN TYPICAL ANTIPSYCHOTICS ARE PRIMARILY METABOLIZED BY CYP 2D6? (MNEMONIC)
"COMMON FELLOWS, HE'S MAKING PROGRESS THERE!" (C-F-H-M-P-T)

- H-HALOPERIDOL (HALDOL)
- M-MOLINDONE (MOBAN)

- T-THIORIDAZINE (MELLARIL)
- SINCE P AND T HAVE MULTIPLE 1ST GEN ANTIPSYCHs TO CHOOSE FROM, PICK THE ONE WITH LOWEST POTENCY.
- EX: THIORIDAZINE HAS VERY LOW POTENCY, BUT THIOTHIXENE AND TRIFLUOPERAZINE HAVE HIGH POTENCY, SO THIORIDAZINE IS THE ONE METABOLIZED BY CYP-2D6.
-
WHICH 2 1ST GEN ANTIPSYCHs ARE 1A2 METABOLIZED?
- THIOTHIXENE (NAVANE)
- TRIFLUOPERAZINE (STELAZINE)
(T=1A2 IF HIGH POTENCY)
BOTH HAVE NO/MINOR INHIBITION.
-
WHICH 1ST GEN ANTIPSYCH IS METABOLIZED BY CYP-3A4, BUT HUGELY INHIBITS CYP-2D6?
PIMOZIDE (ORAP)
(THE MOST POTENT ONE IS ALSO THE MOST UNIQUE METABOLIZER.)
-
WHICH 1ST GEN ANTIPSYCH MODERATELY INHIBITS CYP-3A4?
HALOPERIDOL (HALDOL)
IT ALSO INHIBITS CYP-2D6, WHICH IS ALSO THE PRIMARY ENZYME METABOLIZING HALDOL.
-
WHICH 1ST GEN ANTIPSYCHs INHIBIT CYP-2D6 AT LEAST MODERATELY? (5)
- PIMOZIDE (ORAP) - MAJOR INHIBITION!
- HALOPERIDOL (HALDOL)
- CHLORPROMAZINE (THORAZINE)
- THIORIDAZINE (MELLARIL)
- PERPHENAZINE (TRILAFON)
TAKE YOUR 2 MOST POTENT, 2 LEAST POTENT, AND "TRY LAUGHIN" TO FIND YOUR 5 MODERATE/MAJOR CYP-2D6 INHIBITORS.
