Furosemide
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: Furosemide
Examples of brand names: Lasix [DE]
ATC code: C03CA01
Main use (for orientation): Oedema; heart failure
Documented research summary
Mice: furosemide diuresis unchanged following 7 days of THC pretreatment (2016). Limited negative pharmacodynamic finding. The CBD–ethanol/diuretic work and the 2013 diuresis study are comparisons, not clinical pair-specific drug–drug interactions.
Uncertainties and limitations
Missing data do not establish safety. Research is limited by the documented sources, search terms, languages and accessibility.
Separately recorded findings
1 separately recorded finding. Each statement applies to its documented study context.
THC – laboratory and animal studies
Finding ID: B0430
Type of result: Negative experimental finding
Observation: The diuretic response to furosemide remained unchanged after seven days of THC treatment, unlike the response to a kappa-opioid agonist.
Mechanism: Investigation of functional cross-tolerance in the diuretic response following repeated THC exposure.
Study type: Animal experiment (mouse)
Context studied: Mice received THC 10 mg/kg daily for 7 days; dose–response relationships were then investigated again.
Clinical interpretation: Clinical significance unresolved
Limitations and uncertainties: Abstract read; sequential animal experiment, no general statement on simultaneous treatment in humans or other endpoints.
