Study summary

The purpose of this study is to evaluate the pharmacokinetics of the new formulation of zolpidem hemitartarate orodispersible tablet 3.5 mg in male and female healthy volunteers.

Read the detailed description

This is a phase I study of zolpidem hemitartarate orodispersible tablet 3.5 mg in fasting and postprandial administration. Sample size is 28 volunteers, male and female, aged from 18 to 50 years old.

This is an open-label, randomized, crossover study. Each volunteer will be randomized to one of the following sequencies:

  • Sequency 1: zolpidem hemitartarate orodispersible tablet 3.5 mg in fasting (period 1) and zolpidem hemitartarate orodispersible tablet 3.5 mg postprandial (period 2)
  • Sequency 2: zolpidem hemitartarate orodispersible tablet 3.5 mg postprandial (period 1) and zolpidem hemitartarate orodispersible tablet 3.5 mg in fasting (period 2) Formulation will be administered in a single dose, orally in each period. The volunteers will be admitted in two different periods of 36 hours each, when investigational product will be administered and blood samples will be collected at pre-determined periods of time up to 24 hours for pharmacokinetics evaluation.

Primary objective is to evaluate the pharmacokinetics of the new formulation of zolpidem hemitartarate orodispersible tablet 3.5 mg in healthy volunteers. As a secondary objective, it will be evaluated if there is any pharmacokinetics difference between genders.

Inclusion criteria

  • Male or female volunteers, aged from 18 to 50 years old (women cannot be pregnant or in breastfeeding period and should be committed to use an effective method during the study)

  • Good health conditions or without significant diseases, according to best medical judgment, according to medical history, blood pressure and heart rate measurements, pulse, temperature, physical examination, (ECG) and complementary laboratory tests
  • Ability to understand the nature and objectives of the trial, including risks and adverse events, willingness to cooperate with the researcher and proceed according to all study requirements, which shall be confirmed by form signature.

Exclusion criteria

Exclusion Criteria:

  • Know to the product (Zolpidem) or chemically related compounds
  • History or presence of hepatic or gastrointestinal diseases, or other condition that interferes with drug absorption, distribution, excretion or metabolism
  • Maintenance therapy with any drugs, except oral
  • History of hepatic, kidney, lungs, gastrointestinal, epileptic, hematologic, psychiatric, cardiologic or allergic diseases of any etiology , that requires pharmacological treatment or considered as by the investigator
  • Electrocardiographic findings that at investigator discretion are not recommended for study participation
  • Deviations on screening laboratory results that are considered as clinically relevant by the investigator
  • Smoking
  • Intake of more than five cups of coffee or tea per day
  • History of abusive use of drugs and alcohol
  • Use of regular medication two weeks prior to study enrollment or use of any medications one week prior to study enrollment
  • Hospitalization for any reasons up to 8 weeks prior to start of first period of trial treatment
  • Treatment within 3 months prior to the start of trial treatment, with any drug with known and well-established toxic potential to major organs
  • Participation in any pharmacokinetics trial with more than 300 mL of blood draw or administration of any experimental drug within 12 months prior to trial treatment start
  • Donation or loss of 450 mL or more of blood within 3 months prior to trial enrollment or donation of more than 1500 mL of blood within 12 months prior to the trial treatment start

  • Any condition, according to investigator's best judgment, that prevents the subject to participate in the trial
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 11, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
