Official title
Short-Term Glycemic Effects of Two Concentrations of Liquid Metformin Versus Standard Metformin Tablets in Healthy Adults
Overview
This is an open-label, randomized study evaluating the short-term glycemic effects of two concentrations of liquid metformin formulations (100 mg/mL and 250 mg/mL) compared with standard immediate-release metformin tablets in healthy adult subjects. Participants will receive single or short-term doses of study treatments in a randomized sequence. Blood glucose measurements and other glycemic indicators will be collected to assess short-term pharmacodynamic effects. Safety and tolerability will also be monitored.
Interventions
- Drug Liquid Metformin 100 mg/mL
A single oral dose of a liquid metformin formulation at a concentration of 100 mg/mL will be administered under fasting conditions in one period of the crossover to assess short-term glycemic effects and safety. - Drug Liquid Metformin 250 mg/mL
A single oral dose of a liquid metformin formulation at a concentration of 250 mg/mL will be administered under fasting conditions in one period of the crossover to assess short-term glycemic effects and safety. - Drug Standard Metformin Immediate-Release Tablet
A single oral dose of standard metformin immediate-release tablet(s) will be administered under fasting conditions in one period of the crossover to assess short-term glycemic effects and safety.
Primary outcome measures
- Area Under the Blood Glucose-Time Curve from 0 to 4 Hours Postdose (Glucose AUC₀-₄h) [Time frame: 0 to 4 hours after each study dose in each treatment period]
Eligibility criteria
Inclusion criteria

Exclusion criteria
- Known hypersensitivity or contraindication to metformin or any excipients in the study formulations.
History or presence of any clinically significant cardiovascular, hepatic, renal, gastrointestinal, endocrine, hematologic, neurologic, or psychiatric condition that, in the investigator's judgment, could interfere with study participation or data interpretation.

Donation of ≥450 mL of blood, or significant blood loss, within 8 weeks before the first study dose.
Pregnant or breastfeeding females.
Women of childbearing potential not using acceptable contraception.
Any condition that, in the opinion of the investigator, would make the participant unsuitable for the study.
