Drug-drug Interaction Study of Rifampin and Anaprazole Sodium

This is an open-label, single-center, two-period, single-sequence crossover drug-drug interaction study of rifampin capsules and anaprazole sodium enteric-coated tablets in healthy adult subjects. On Day 1 and Day 10, subjects will orally receive a single 60 mg dose of anaprazole sodium enteric-coated tablets in the morning under fasting conditions. From Day 4 to Day 11, subjects will orally receive 600 mg of rifampin capsules once daily (QD) in the morning under fasting conditions for 8 consecutive days. Specifically, on Day 10, subjects will orally receive both a single 60 mg dose of anaprazole sodium enteric-coated tablets and a 600 mg dose of rifampin capsules in the morning under fasting conditions. Pharmacokinetics will be followed from Day 1 through Day 12.
