Oral pilocarpine for treatment of opioid-induced oral dryness in healthy adults
Abstract
Pilocarpine induces a profuse flow of saliva when administered orally, but effects on drug-induced oral dryness have not been examined. The aim of this trial was to investigate if pilocarpine increases production of saliva in individuals suffering from dry mouth due to treatment with opioids. Sixty-five individuals were enrolled in a randomized, double-blind, placebo-controlled trial. The subjects received tramadol (50 mg t.d.s.) to induce oral dryness, and were thereafter assigned to one of three groups. Secretion rate of saliva was measured before and after tramadol, and after the oral administration of pilocarpine (5 mg), placebo, or no treatment. Baseline characteristics did not differ among the groups (mean ± SEM: 0.37 ± 0.06 mL/min), and tramadol lowered the secretion at the same level in all groups (0.15 ± 0.02 mL/min). Pilocarpine increased the flow above that observed with placebo (0.66 ± 0.19 vs. 0.15 ± 0.02 mL/min). Thus, pilocarpine re-establishes the flow of saliva in the state of tramadol-induced oral dryness.

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.
