Abstract
Purpose: The tablet form of tacrolimus is more convenient for drug ingestion than the capsule form. We examined the efficacy and safety of tacrolimus tablets and a satisfaction survey after formula conversion in liver transplant (LT) recipients.
Methods: This study was an open-label, prospective clinical trial for tacrolimus formula 1:1 conversion from capsule to tablet in 41 adult LT recipients with tacrolimus maintenance therapy of more than 1 month. The primary endpoint was incidence of biopsy-proven acute rejection (BPAR) within 24 weeks. Surveys 1 week before and 4 weeks after formula conversion were conducted for total daily dose of medication, number, scale of discomfort and satisfaction.
Results: The overall incidence of BPAR was 0% and there was no graft loss or patient death. The incidence of adverse effects was 34.1% (n = 14) after formula conversion. The most common severe adverse effect was abnormal liver function test (n = 5): biliary complications (n = 4) and alcoholic recidivism (n = 1). Total daily dose and number of tacrolimus doses were significantly lower after formula conversion (P < 0.05) without changes in trough level. According to survey analysis, there was no significant difference in discomfort and satisfaction scales from capsule to tablet conversion (P < 0.05).
Conclusion: The present study suggests that the new tablet formula can be a useful treatment option to maintain a consistent level of tacrolimus with a lower total daily dose and number in adult LT recipients.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
