Keine synergistische Wirkung der Kombination von ∆9-Tetrahydrocannabinol und Piritramid bei postoperativen Schmerzen
Abstract
Background It is concluded from animal experiments that cannabinoid receptor and mu-opioid receptor agonists act synergistically with respect to antinociception. In order to demonstrate this effect under clinical conditions, we conducted a randomized double blind trial with patients after radical prostatectomy.Patients and methods From the evening before the operation until the morning of the second postoperative day, all patients received eight oral doses of either placebo or 5 mg Delta(9)-tetrahydrocannabinol (dronabinol). Postoperatively patients had access to patient-controlled analgesia with the micro-opioid agonist piritramide for 48 h. We expected patients receiving dronabinol to require significantly less piritramide compared to patients on placebo.Results The consumption of piritramide was recorded in 100 patients after radical retropubic prostatectomy with regional lymphadenectomy. Patients in the placebo group consumed 74 mg (median), interquartile range (IQR) 44-90 mg, patients in the verum group consumed 54 mg (median) IQR 46-88 mg. The difference between groups was not statistically significant. Plasma concentrations of Delta(9)-THC were measurable in all patients in the verum group. The levels (median) were 1.5 ng/ml (IQR 0.6-2.3), 1.3 ng/ml (IQR 0.5-2.2) and 1.9 ng/ml (IQR 0.8-2.7) on the day of operation, the first and second postoperative day, respectively.Conclusion We found neither a synergistic nor even an additive antinociceptive interaction between Delta(9)-tetrahydrocannabinol and the micro-opioid agonist piritramide in a setting of acute postoperative pain.

Two controlled studies found no effect of cannabinoids on opioid dose requirements.
“Two controlled studies found no effect of cannabinoids on opioid dose requirements (Johnson et al, 2010;Seeling et al, 2006).”
From Opioid-Sparing Effect of Cannabinoids: A Systematic Review and Meta-Analysis (2017) · cites this paper as Seeling et al, 2006
In Seeling 2006, median dose of piritramide alone was 74 mg (IQR 44-90) compared with 54 mg (IQR 46-88) when administered with dronabinol; the difference between intervention and control group was not significant; no evidence was found of synergistic antinociceptive interaction between delta-9-THC and piritramide for acute postoperative pain.
“Median dose of piritramide alone was 74 mg (IQR 44-90) compared with 54 mg (IQR 46-88) when administered with dronabinol.”

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.
