Cariprazine
For an informed discussion with your doctor or pharmacist. This information collection is not a clinically validated interaction checker. Missing data do not establish safety. Do not change or stop prescribed medicines on the basis of this information. The findings apply to the specific conditions studied; laboratory and animal studies cannot be directly extrapolated to humans.
Active substance: Cariprazine
Examples of brand names: Reagila [EU/DE]
ATC code: N05AX15
Main use (for orientation): Schizophrenia
Documented research summary
A retrospective case report from an adverse-event collection describes abdominal pain and liver injury with cariprazine plus THC-dominant cannabis, with concomitant etoricoxib/chondroitin. CYP3A4 inhibition is hypothetical; concentrations are absent. Positive treatment courses in cannabis use disorder do not refute the signal.
Uncertainties and limitations
Does not establish safety for less-studied cannabinoids or untested formulations/doses.
Do not infer clinical dosage from preclinical effects or enzyme hypotheses.
Separately recorded findings
1 separately recorded finding. Each statement applies to its documented study context.
THC/CBD-containing cannabis (THC 20%, CBD 1%; not an isolate study) – clinical signals
Finding ID: B0332
Type of result: Clinical case signal; causal attribution uncertain
Observation: Abdominal pain and hepatotoxicity (ALT 850 U/L, GGT 480 U/L) in a 65-year-old woman.
Mechanism: Suspected CYP3A4 inhibition; not confirmed by concentration measurements.
Study type: Retrospective evaluation of adverse-event reports; one cariprazine case
Context studied: Cannabis for osteoarthritis pain; cariprazine dose not stated; concomitant etoricoxib and chondroitin sulphate. Overall collection of 20 selected suspected interaction cases, not exposure-based incidence.
Clinical interpretation: Specific clinical warning signal, not a quantified risk or direct proof of a pharmacokinetic mechanism.
Limitations and uncertainties: Multiple medicines and selected reports; no measured drug/cannabinoid concentrations, no isolated THC/CBD attribution. Authors' hypotheses not adopted as proven mechanisms.
