Abstract

Background: Currently, there are no established pharmacotherapies for cannabis use disorders (CUDs). As a long-acting alpha-2-adrenergic receptor agonist, guanfacine extended-release (G-XR) could be useful in the treatment of CUDs by mitigating withdrawal and improving behavioral control.Objectives: To evaluate the feasibility and tolerability of G-XR as a treatment for CUDs.Methods: In an eight-week open-label outpatient pilot trial, we evaluated the safety and tolerability of G-XR in 22 cannabis dependent individuals. Using 2 different titration schedules, G-XR was gradually titrated to a dose of 4 mg or the highest dose tolerated. All participants received standard medication management.Results: Retention at week eight was 41%. Average daily amount of cannabis use (in grams: F1,86 = 8.74, p = .004; in dollars: F1,86 = 16.67, p < .0001) and cannabis using days (F1,86 = 7.67, p = .007) significantly reduced over the course of study participation. There were no significant differences between the titration schedules on emergence of side effects (Fisher exact test, p = .378) or retention (Log-Rank Test X21 = 0.021, p = .886). A total of 3 participants achieved 3 weeks or greater of total abstinence.Conclusions: G-XR is a feasible treatment for CUDs, and should be evaluated further in an efficacy trial.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
