About this study

This is an open-label, randomized, crossover study with 02 treatments, 02 sequences, and 02 periods, in which the healthy volunteers received, in each period, the test or the reference formulation after standardized meals. Test product is Rosiglitazone Maleate + Metformin - Avandamet 4 mg + 1000 mg (GlaxoSmithKline Brasil Ltda) in the form of film coated tablets. Reference product is Rosiglitazone Maleate + Metformin - Avandamet 2 mg + 500 mg (Glaxo Smith Kline Brasil Ltda) in the form of film coated tablets. The population is composed by 26 healthy volunteers, adults, of both genders and their ages varied between 18 and 50 years. Their body mass index (BMI) varied between 18,5 and 25. There are no restrictions regarding the ethnic group. The relative bioavailability of the two formulations, after oral administration, will be evaluated based on statistical comparisons of relevant pharmacokinetic parameters obtained from data of drug concentration in blood.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Exclusion criteria

  • The volunteer has a known hypersensitivity to the study drug or to compounds chemically related;

  • History of neurological, endocrine, pulmonary, hamatologic, immune, brain, metabolic or cardiovascular illness;
  • Hypo or hypertension of any etiologic that needs pharmacologic treatment;
  • The results of the laboratory exams are out of the values considered as normal according this protocol's rules, unless that they are considered as clinically irrelevant by the investigator;

Primary outcomes

  1. AUC0-t of Rosiglitazone Maleate

    Time frame: Day 1 (day that blood collection started) and Day 2 (Period 1) and Days 8 and 9 (Period 2)

    The area under the plot of plasma concentration of drug against time after drug administration is defined as the area under the curve (AUC). The AUC 0-t is calculated from time 0 (prior to administration of medication) to time t (the time of the last quantifiable concentration). The AUC is of particular use in estimating the bioavailability of drugs, by measuring the extent of absorption. ng, nanograms; ml, milliliter.

  2. Cmax of Rosiglitazone Maleate

    Time frame: Day 1 (day that blood collection started) and Day 2 (Period 1) and Days 8 and 9 (Period 2)

    Cmax is defined as the maximum or "peak" concentration of a drug observed after its administration. Cmax is one of the parameters of particular use in estimating the bioavailability of drugs, by measuring the total amount of drug absorbed.

  3. AUC0-infinity of Rosiglitazone Maleate

    Time frame: Day 1 (day that blood collection started) and Day 2 (Period 1) and Days 8 and 9 (Period 2)

    The area under the plot of plasma concentration of drug against time after drug administration is defined as the area under the curve (AUC). The AUC0-infinity is calculated from time 0 (prior to administration of medication) to infinity (the time of complete elimination of the drug). The AUC is of particular use in estimating the bioavailability of drugs, by measuring the extent of absorption.

  4. AUC0-t of Metformin Hydrochloride

    Time frame: Day 1 (day that blood collection started) and Day 2 (Period 1) and Days 8 and 9 (Period 2)

    The area under the plot of plasma concentration of drug against time after drug administration is defined as the area under the curve (AUC). The AUC0-t is calculated from time 0 (prior to administration of medication) to time t (the time of the last quantifiable concentration). The AUC is of particular use in estimating the bioavailability of drugs, by measuring the extent of absorption. ng, nanograms; ml, milliliter.

  5. AUC0-infinity of Metformin Hydrochloride

    Time frame: Day 1 (day that blood collection started) and Day 2 (Period 1) and Days 8 and 9 (Period 2)

    The area under the plot of plasma concentration of drug against time after drug administration is defined as the area under the curve (AUC). The AUC0-infinity is calculated from time 0 (prior to administration of medication) to infinity (the time of complete elimination of the drug). The AUC is of particular use in estimating the bioavailability of drugs, by measuring the extent of absorption.

  6. Cmax of Metformin Hydrochloride

    Time frame: Day 1 (day that blood collection started) and Day 2 (Period 1) and Days 8 and 9 (Period 2)

    Cmax is defined as the maximum or "peak" concentration of a drug observed after its administration. Cmax is one of the parameters of particular use in estimating the bioavailability of drugs, by measuring the total amount of drug absorbed.
