Summary

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

Type	Name	Description
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.
