Trial summary

Unbranded drug molecules are produced after the patent of a given drug has expired. Unbranded molecules of Remifentanil have been marketed in Colombia, and several reports by anesthesiologist indicate that there are differences in the physiologic response of patients to these molecules.

About this study

Official title: Pharmacodynamic Differences Between Branded and Unbranded Remifentanil Molecules Available in Colombia for Tracheal Intubation of Adult Patients, 2012-2013

Unbranded drug molecules are produced after the patent of a given drug has expired. Unbranded molecules of Remifentanil have been marketed in Colombia, and several reports by anesthesiologist indicate that there are differences in the physiologic response of patients to these molecules. The investigators hypothesized that unbranded molecules of remifentanil require higher doses to obtain desired physiological responses as compared to the branded molecule.

Read the detailed description

Introduction. Several remifentanil products are commercialized in Colombia while these have never been compared in a clinical setting.

Objective. The aim of this study was to investigate the pharmacodynamic profile of the innovative molecule of remifentanil (group O = Ultiva®) and two unbranded molecules (group A = Remifentanil Laboratorios Chalver de Colombia S.A. and group B = Fada Remifentanilo) registered in Colombia.

Methods. The investigators carried out a double-blind, randomized, controlled trial. The branded molecule of remifentanil (group O, n=29) was compared against the two unbranded molecules (group A, n=29; group B, n=32) during anesthetic induction and tracheal intubation in adult patients American Society of Anesthesiology Physical Status Classification = I without predictors for difficult airway. The target controlled infusion (TCI) doses evaluated were 6, 8 and 10 ng/ml with the Minto model. Induction was complemented with propofol 5 mg/ml (TCI) with the Schneider model and rocuronium 0.6 mg/kg. The primary outcome was defined as the difference in mean arterial pressure and heart rate pre-intubation (TCI equilibrium) and post-intubation (maximum measurement within 5 minutes).

What is being measured

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

  1. Composite outcome of heart rate or mean arterial pressure difference before and after tracheal intubation

    Heart rate measured with EKG. Mean arterial pressure measured with automatic blood pressure cuff.

    Measured: Average of 5 minutes

Secondary outcomes (1)
  1. Cooper intubation condition score

    Jaw relaxation: 0 poor, 1 minimum, 2 moderate, 3 good. Vocal cords: 0 closed, 1 closing, 2 moving, 3 open. Intubation response: 0 severe cough, 1 mild cough, 2 mild diaphragmatic movement, 3 no response.

    Cooper score: Jaw relaxation + Vocal cords + Intubation response

    Measured: Measured during tracheal intubation, average of 30 seconds

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Remifentanyl, Ultiva®, Remifentanil Laboratorios Chalver de Colombia S.A. and Fada Remifentanilo in people with Pain, run by Fundación Universitaria de Ciencias de la Salud at 1 site in Colombia.

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 4 inclusion and 3 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 29 Jan 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Colombia. Whether a site is taking part right now should be confirmed with that site. See every site.

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Composite outcome of heart rate or mean arterial pressure difference before and after tracheal intubation (time frame: Average of 5 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02048293, which also lists 3 linked publications.

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 29 Jan 2014.
