Interest in dietary fiber has been growing due to the many benefits it has for health. It is well known that dietary fiber reduces the risk of developing health problems such as obesity, hypertension, constipation, type 2 diabetics and hyperlipidemia. However, dietary fiber is also known to reduce the bioavailability of minerals, nutrients and certain drugs, though the interaction between dietary fiber and drugs is still poorly understood. In this study, we examined the adsorption of drugs (theophylline, acetaminophen, metoprolol, chlorpromazine, imipramine, amitriptyline and diclofenac sodium) onto several types of dietary fiber (cellulose, chitosan, pectin, sodium alginate and glucomannan) at pH 3 and pH 7 in order to determine the in vitro adsorption characteristics of dietary fiber. Our findings indicated that adsorption of drugs onto dietary fiber ranged from 0 to 96%, varying with the types of dietary fiber and drugs, and pH. Chlorpromazine, imipramine and amitriptyline showed particularly marked adsorption onto sodium alginate and glucomannan. We considered that ionic bonding was one of the reasons for adsorption.These findings indicate the possibility of the bioavailability of drugs being reduced when they are taken with dietary fiber due their adsorption onto dietary fiber.

This study was undertaken in order to evaluate the effectiveness of interventions by the Department of Infection Control and Prevention in promoting the proper use of antibiotic drugs for methicillin resistant Staphylococcus aureus (MRSA) prescribed to inpatients.We performed 3 interventions : 1.Protocol improvement for anti-MRSA drug use ; 2.Change in alcohol-based handrub and training in hand hygiene and 3.Devised reporting system for drug use.The effects of the interventions were determined by segmented regression analysis of interrupted time series for drug usage and cost before and after the interventions were commenced.The change in slope of drug use was -1.05 vials/1000 inpatients per month (95% Confidence interval (C.I.) -2.84,0.74)and the change in level was -8.21 vials/1000 inpatients (95% C.I.-14.67,-1.75).There was a significant decrease in the ratio of the patients receiving anti-MRSA drugs to MRSA incidence between before and after the interventions.These results suggested that usage of anti-MRSA drugs was immediately reduced by the interventions to promote the proper use of drugs.An ordinary estimate of reduction in costs was ¥29 million per year while a more conservative estimate produced a decrease of ¥20 million per year.These findings suggest that monitoring antimicrobial use and promoting the proper use of antibiotics for MRSA are important roles for pharmacists to perform.
