Abstract:Introduction: Adsorption capacity of activated charcoal to paracetamol was determined at simulated gastric environment, pH 3.4 and simulated intestinal environment pH 7.2. Three formulations of activated charcoal; powder, capsule and suspension were tested. Paracetamol was derived from tablet to simulate in vivo intoxication conditions.Methods: Activated charcoal and paracetamol were mixed at both the pHs. The amount of activated charcoal was varied to obtain activated charcoal-paracetamol ratio from 10:1 to 1:1. Then the mixtures were shaken, filtered and the content of remaining paracetamol was determined by UV spectrophotometer. 4 and 263.64 [229.13; 298.15] at pH 7.2 for suspension. The effect of pH on adsorption capacity was not significant. ResultsDiscussion: Under simulated conditions, the three formulations of activated charcoal adsorbed sufficient amount of paracetamol. The data show that activated charcoal 1g/kg body weight is sufficient a poisoned patient from if given shortly after intoxication.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
