Conditions: Healthy
Allocation: RANDOMIZED | Intervention model: CROSSOVER
Enrollment: 48
Healthy volunteers: yes

Brief summary:
The aim of the trial is to assess the relative bioavailability of fixed dose combination tablets of linagliptin and metformin compared to the administration of two single tablets (linagliptin and metformin ) in Chinese subjects. The availability of a fixed dose combination tablet is expected to significantly enhance patients' compliance with antidiabetic treatment., in particular with concern to the frequent polypharmacy in diabetic patients.

Detailed description:

Arms:
arm 1: 24 subjects (12 male and 12 female) will be assigned to 2 treatment sequences. cross-over design was adopted to ensure each patient would take fixed dose combination tablets of linagliptin /metformin (high dose) and single linagliptin and metformin (high dose) tablets single dose in randomized order arm 2: 24 subjects (12 male and 12 female) will be assigned to 2 treatment sequences. cross-over design was adopted to ensure each patient would take fixed dose combination tablets of linagliptin /metformin (low dose) and single linagliptin and metformin (low dose) tablets single dose in randomized order

Interventions: intervention 1: linagliptin/metformin(high dose) intervention 2: Linagliptin/metformin(low dose)
Intervention descriptions: intervention 1: patient would take fixed dose combination tablets of linagliptin /metformin (high dose) and single linagliptin and metformin (High dose) tablets single dose in random order, and each dosage will be separated in 42 days interval. intervention 2: patient would take fixed dose combination tablets of linagliptin /metformin (low dose) and single linagliptin and metformin (Low dose) tablets single dose in random order, and each dosage will be separated in 42 days interval.
