Effect of Tegoprazan or RAPA114 on Pharmacokinetic of Atorvastatin in Healthy Adult Volunteers

An Open-label, Randomized, Multiple-dose, Replicated Crossover Study to Evaluate Drug-drug Interaction Following Co-administration of Tegoprazan or RAPA114 With Atorvastatin in Healthy Adults

This study aims to evaluate the influence of tegoprazan or RAPA114 on the Pharmacokinetic characteristics of atorvastatin following co-administration of tegoprazan or RAPA114 in healthy adult volunteers.

[Pharmacokinetic Assessments] : Blood concentration of atorvastatin, 2-OH atorvastatin

• Primary outcome: AUCτ, Css,max of atorvastatin
• Secondary outcome: Tss,max of atorvastatin, AUCτ, Css,max of 2-OH atorvastatin, metabolic ratio

[Sefety Assessments]

: Safety assessments with adverse event monitoring including subjective/objective symptoms, physical examination, vital signs, electrocardiogram, and laboratory test
