What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on studying the medication Pregabalin, which is commonly used to treat conditions like nerve pain, epilepsy, and anxiety disorders. In this study, two different forms of Pregabalin are being compared: a 300 mg tablet called Pregabalina Normon and a 300 mg hard capsule known as Lyrica. The trial involves healthy volunteers who will receive a single dose of each formulation to see how the body absorbs the medication.

The purpose of the study is to evaluate the relative bioavailability, which means understanding how much of the drug enters the bloodstream and how quickly it does so. This will help determine if the two forms of Pregabalin are bioequivalent, meaning they work in the same way and provide the same benefits. Participants will take the medication under fasting conditions, which means they will not eat before taking the dose, to ensure consistent results.

Throughout the study, participants will be monitored to ensure their safety and to collect data on how the medication is processed by the body. The trial is designed to provide valuable information about the effectiveness and safety of these two formulations of Pregabalin, contributing to better treatment options for patients in the future.

The research process

The trial runs in 7 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Joining the study

    Upon joining the study, participants are required to provide written consent after being informed about the study's design, objectives, and potential risks. Participation is voluntary, and consent can be withdrawn at any time.

  2. Step 2

    Initial health assessment

    Participants undergo a health assessment to ensure they meet the study's inclusion criteria. This includes a review of medical history, a physical examination, and laboratory tests to check blood and urine samples. Vital signs and an electrocardiogram are also performed to ensure no significant health issues are present.

  3. Step 3

    First medication administration

    Participants receive a single oral dose of pregabalin 300 mg in the form of either a hard capsule or a tablet. This is done under fasting conditions, meaning no food is consumed for a specified period before taking the medication.

  4. Step 4

    Monitoring and data collection

    After taking the medication, participants are monitored for a period to collect data on how the body absorbs and processes the drug. This involves measuring the concentration of the drug in the blood at various times to determine the bioavailability of the medication.

  5. Step 5

    Crossover and second medication administration

    In a crossover design, participants will later receive the alternative formulation of pregabalin (either the capsule or the tablet, depending on what was initially received). This allows for comparison between the two formulations.

  6. Step 6

    Final monitoring and data collection

    Similar to the first administration, participants are monitored after taking the second formulation. Data is collected to compare the bioequivalence of the two formulations, ensuring they have similar effects in the body.

  7. Step 7

    Completion of the study

    Upon completion of all required steps, participants may undergo a final health assessment to ensure no adverse effects have occurred. The study concludes with the collection of all data for analysis.

Investigated drugs

Pregabalin is a medication used in this clinical trial to compare two different forms: tablets and hard capsules. The purpose of the trial is to see if the body absorbs both forms in the same way when taken by healthy volunteers who have not eaten. Pregabalin is often used to treat nerve pain, seizures, and anxiety. In this study, researchers want to make sure that the new tablet form works just as well as the capsule form that is already available. This helps ensure that patients can expect the same effects and safety from both forms of the medication.

What is already known about the treatment

Pregabalin – Pregabalin is administered orally and is available in the form of tablets or hard capsules. It is currently being studied in a clinical trial to compare the bioavailability of a new tablet formulation with the existing capsule form in healthy volunteers. Pregabalin is primarily used to treat nerve pain, epilepsy, and anxiety disorders. It works by binding to certain calcium channels in the brain, which helps to reduce the release of neurotransmitters and decrease nerve activity. Pregabalin is classified as an anticonvulsant and neuropathic pain agent.

Investigated diseases

Healthy volunteers – This term refers to individuals who do not have any known significant health conditions or diseases. They are typically used in clinical trials to establish baseline data or to test new treatments or medications. Healthy volunteers are expected to have normal physiological functions and are free from any chronic or acute illnesses. Their participation helps researchers understand how a drug or treatment behaves in a body without the influence of existing health issues. The progression of their health status is generally stable, as they do not have underlying conditions that could alter the study's outcomes.
