Online Spectroscopic Monitoring of Drug Release Kinetics from Nanostructured Dual-Stimuli-Responsive Conducting Polymer.
Article in Pharmaceutical research, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeThe potential of electrochemical/temperature dual stimuli-responsive conducting polymer to be used as general drug delivery systems. It allows on-demand release of incorporated drug is kinetically investigated in real time.
methodsOnline spectroscopic monitoring was used to investigate the electrochemically/thermally controlled release behavior of a model drug (naproxen) from drug-doped polypyrrole (DDPPy) film. Avrami's equation has been used to study the kinetics and further analyzing has been carried out using the Arrhenius and the Eyring equations. Furthermore, drug release behavior, with two other electrochemical techniques was investigated.
resultsIt was observed both temperature and electrical stimuli increase the rate of release while electrical potential has a greater effect as revealed in the values of release rate constant (from 0.0068 to 0.018 min
conclusionThe electronic properties of the conducting polymer has an important role in release kinetics, there might be a single mechanism with the same limiting step. In addition, it was demonstrated the rate of drug release from DDPPy dramatically depends on the amounts as well as modes of applying potential which provides enhanced control of drug-release kinetics which can be accelerated or even sustained.
