Interaction Details
dabigatran is classified as belonging to the following category: P-Glycoprotein Substrates
Theoretically, THC might alter levels of drugs that are substrates of P-glycoprotein (P-gp).
Most in vitro research suggests that THC can inhibit P-gp and increase the accumulation of probe compounds by reducing P-gp mediated drug efflux. In vitro studies in kidney cell lines show that a 1-hour exposure to CBD and THC inhibits P-gp. THC may also alter the expression of P-gp, although this effect appears to vary based on duration of exposure. Some in vitro research in lymphoblastoid leukemia cell lines indicates that a 1-hour exposure to cannabinoids does not affect P-gp expression, while a prolonged 72-hour exposure decreases P-gp expression. Other in vitro research in these cell lines shows that a 4-hour exposure to THC and CBD induces P-gp gene expression, while exposure for longer than 4 hours and up to 48 hours does not induce P-gp gene expression.

Interaction Details
dabigatran is classified as belonging to the following category: Anticoagulant/Antiplatelet Drugs
Theoretically, THC might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
In vitro research shows that THC inhibits platelet aggregation.

Delta-9-tetrahydrocannabinol (thc) Overview
dabigatran Overview
-
Dabigatran is used to treat deep vein thrombosis (DVT; a blood clot, usually in the leg) and pulmonary embolism (PE; a blood clot in the lung) in adults and children 3 months of age and older who have been treated with an injectable anticoagulant ('blood thinner'). It is also used to reduce the risk of a DVT and PE from happening again after initial treatment is completed in adults and children 3 months of age and older. Dabigatran is used to help prevent DVT and PE in adults who have had hip replacement surgery. Dabigatran is also used to help prevent strokes or serious blood clots in adults who have atrial fibrillation (a condition in which the heart beats irregularly, increasing the chance of clots forming in the body, and possibly causing strokes) without heart valve disease. Dabigatran is in a class of anticoagulant medications called direct thrombin inhibitors. It works by preventing blood clots from forming in the body.
