Effects of fendiline on cocaine-seeking behavior in the rat.
Article in Psychopharmacology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
rationaleL-type Ca(2+) channels (LTCC) and GABAB receptors are both possible targets in the development of new pharmacological compounds for cocaine addiction. Drugs that target either receptor attenuate a wide range of cocaine-seeking behaviors in the rat. However, there is no current human-approved pharmacotherapeutic intervention for psychostimulant addiction.
objectivesThis study examined the effects of a human-approved LTCC blocker, fendiline, on cocaine-taking and cocaine-seeking behavior in rats. The effects of combining fendiline with the GABAB receptor agonist baclofen on cocaine self-administration were also tested.
methodsMale Wistar rats were trained to self-administer cocaine, and the effects of fendiline pretreatment (vehicle, 1.78, 3.16, 5.62 mg/kg, intraperitoneal (IP)) were tested on progressive ratio responding and cue- and drug-induced reinstatement. The effects of baclofen (vehicle, 0.56, 1.78, 3.16, 5.62 mg/kg, IP) combined with fendiline (5.62 mg/kg, IP) were tested on progressive ratio responding. Control experiments measured locomotor activity and lever pressing for food in rats that received both baclofen and fendiline prior to the test session.
resultsAcute injections of fendiline prior to cue- or drug-induced reinstatement significantly attenuated lever-pressing behavior (p < 0.05). Fendiline and baclofen, but not fendiline alone, not only significantly attenuated breakpoints, but also impaired general motor behavior and naturalistic reinforcement (p < 0.05).
conclusionThese data suggest that the LTCC blocker fendiline may represent a novel pharmacotherapeutic intervention to prevent reinstatement to cocaine seeking. Also, co-administration of fendiline and baclofen not only can attenuate the motivation to take cocaine, but also impairs general motor behavior and naturalistic reinforcement.
