About this study

Official title: A Pharmacokinetic and Pharmacodynamic Study Comparing Metoprolol IR and Metoprolol CR/XL Subsequent to Initial Treatment With Intravenous and/or Oral Metoprolol in Patients With Suspected Acut Myocardial Infarction

The objective of the study was to compare treatment with two different oral formulations of metoprolol, metoprolol immediate release (IR) and metoprolol extended release (CR/XL) in patients with acute myocardial infarction regarding the following:

Pharmacokinetics, peak and trough plasma concentrations and area under the plasma concentration curve.

Pharmacodynamics, hourly means of Holter recorded heart rate. Tolerability. An open, randomised design with two parallel groups was employed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pharmacokinetic profile in terms of Cmax, Cmin, AUC

    Assesment following multiple dosing of metoprolol CR/XL 200 mg once daily, or multiple dosing of metoprolol IR 200 mg daily in divided doses

    Measured: Treatment duration: 4 days

  2. Pharmacodynamics in terms of Hourly means of heart rate (Holter recorded)

    Assesment following multiple dosing of metoprolol CR/XL 200 mg once daily, or multiple dosing of metoprolol IR 200 mg daily in divided doses

    Measured: Treatment duration: 4 days

  3. Safety profile in terms of adverse events

    Measured: Treatment duration: 4 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Metoprolol- Toprol XL and Metoprolol- Lopressor in people with Acute Myocardial Infarction, run by AstraZeneca.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pharmacokinetic profile in terms of Cmax, Cmin, AUC (time frame: Treatment duration: 4 days). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Feb 2012.
