The effect of food on the high clearance drug asenapine after sublingual administration to healthy male volunteers.
Trial report in European journal of clinical pharmacology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo determine the effects of food on the pharmacokinetics of sublingual asenapine.
methodsHealthy male volunteers (n=26, age 19-53 years) randomly received a single sublingual dose of asenapine 5 mg after ≥ 10 h fasting (Treatment A, reference), after a high-fat meal (Treatment B) and after ≥ 10 h fasting with a high-fat meal at 4 h post-dose (Treatment C). Blood samples were drawn over 72 h to measure asenapine plasma concentrations. Effects of food intake on asenapine pharmacokinetics were assessed using bioequivalence criteria and evaluated using a compartmental modelling analysis.
resultsCompared with the reference, mean asenapine exposure (AUC0-last and AUC0-∞) was approximately 20 % lower after intake of a high-fat meal prior to dosing, whereas Cmax decreased by only about 10 %. When a high-fat meal was taken 4 h post-dose in the fasting state, asenapine concentrations were similar to the reference during the first 4 h post-dose. After the meal intake, asenapine concentrations decreased quickly for several hours. Compartmental modelling indicated that a transient 2.5-fold increase in asenapine clearance after eating could explain the asenapine concentration-time profiles for both food regimens.
conclusionsTo our knowledge, this is the first study investigating the effect of food upon the sublingual administration of a drug. A high-fat meal taken before or 4 h post-dose of sublingual asenapine indirectly caused a transient increase in liver blood flow that resulted in a temporal increase in asenapine clearance. As the effects on asenapine exposure were small and not clinically relevant, no additional restrictions are required for the timing of food intake in relation to asenapine dosing.
