The objective of the study was to assess the bioequivalence of Lendormin Tablets (Delpharm Reims) vs. Lendormin Tablets (Synmosa Biopharma Co. Ltd.) following oral administration

Condition Intervention Phase
Drug: Lendormin tablet
Drug: Brotizolam tablet
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Randomized, Single-dose, Two-way Cross-over Study to Assess the Bioequivalence of Lendormin Tablets 0.25 mg (Delpharm Reims) vs. Lendormin Tablets 0.25 mg (Synmosa Biopharma Co. Ltd.) Administered to Healthy Adult Volunteers

Further study details as provided by Boehringer Ingelheim:

Primary Outcome Measures:
  • Cmax: Peak drug concentration obtained directly from the data without interpolation [ Time Frame: One month ]
  • kel:Plasma elimination rate constant determined by simple linear regression based on the terminal phase of plasma concentration [ Time Frame: One month ]
  • Tmax:Time to peak drug concentration obtained directly from the data without interpolation [ Time Frame: One month ]
  • T 1/2: Plasma half-life estimated by (0.693/kel) [ Time Frame: One month ]
  • MRT : Mean residence time [ Time Frame: One month ]
  • AUMC : Area under the ( first) moment plasma concentration - time curve [ Time Frame: One month ]
  • AUC 0-t: Area under the plasma concentration-time curve from zero to the last quantifiable concentration determined by the traperoidal rule [ Time Frame: One month ]
  • AUC 0- : Area under the plasma concentration-time curve from time zero to infinity determined by the trapezoidal rule and extrapolated to infinity estimated by the last quantifiable concentration (Cn) divided by kel [ Time Frame: One month ]

Secondary Outcome Measures:
  • Blood pressure [ Time Frame: one month ]
  • heart rate [ Time Frame: one month ]
  • body temperature [ Time Frame: One month ]
  • 12 Laed ECG, Lab Test ( Hematocrit, WBC count with differential, RBC count and platelet count ; SGOT ( AST), SGPT (ALT) , alkaline phosphatase, total bilirubin, albumin, glucose, BUN, creatinine,uric acid, total cholesterol and TG) [ Time Frame: One month ]
