About this study

Official title: Oral Amantadine Versus Gabapentin to Attenuate the Hemodynamic Response to Laryngoscopy and Tracheal Intubation and Their Effect on β-endorphin

To evaluate the effect of oral amantadine versus gabapentin premedication on the hemodynamic response to laryngoscopy and tracheal intubation and their effect on β-endorphins.

Read the detailed description

Direct laryngoscopy and passage of endotracheal tube through the larynx is a noxious stimulus, which can provoke untoward response in the cardiovascular, respiratory and other physiological systems. Gabapentin, is 1-aminomethyl cyclohexane acetic acid.Gabapentin is structurally related to the neurotransmitter gamma-aminobutyric acid (GABA). Gabapentin act in central nervous system CNS), it acts by decreasing the synthesis of neurotransmitter glutamate and by binding to the alpha 2 delta subunits of voltage dependent calcium channels.

Amantadine is a non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist, and compared to ketamine, it is well tolerated with fewer side effects (mainly dizziness, sedation, and dry mouth). Amantadine's formulation permits the oral route for drug delivery, as well as the IV route. The side-effects profile of amantadine via all routes seems not to be harmful in appropriate dosages.. Amantadine has been clinically used as an antiviral drug, for dementia, and in the treatment of Parkinson's disease and spasticity. It is a non-competitive NMDA receptor antagonist, and compared to ketamine, it is well tolerated with fewer side effects (mainly dizziness, sedation, and dry mouth). Amantadine's formulation permits the oral route for drug delivery, as well as the IV route. The side-effects profile of amantadine via all routes seems not to be harmful in appropriate dosages.

In the central nervous system, beta-endorphins bind mu-opioid receptors and exert their primary action at presynaptic nerve terminals. However, instead of inhibiting substance P, they exert their analgesic effect by inhibiting the release of GABA, an inhibitory neurotransmitter, resulting in excess production of dopamine.

The investigators designed this study to prove the efficacy of oral amantadine versus gabapentin premedication on the hemodynamic response to laryngoscopy and tracheal intubation and their effect on β-endorphins.

What is being measured

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

  1. effect of oral amantadine versus gabapentin premedication on laryngoscopy and tracheal intubation on β-endorphins.

    analysis of change of β-endorphins in blood sample

    Measured: baseline blood sample taken before drug administration and after 15 minutes after intubation and before skin incision

Secondary outcomes (2)
  1. effect of oral amantadine versus gabapentin premedication on the Mean arterial blood pressure due to laryngoscopy and tracheal intubation

    change of Mean arterial blood pressure

    Measured: baselineMAP before drug administration and after 15 minutes after intubation and before skin incision

  2. effect of oral amantadine versus gabapentin premedication on the heart rate due to laryngoscopy and tracheal intubation

    change of heart rate

    Measured: baseline heart rate before drug administration and after 15 minutes after intubation and before skin incision

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing oral amantadine sulfate and oral gabapentin in people with Effect of Laryngoscopy and Tracheal Intubation, run by Ghada Mohammed AboelFadl at 1 site in Egypt.

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 1 inclusion and 6 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 25 Sep 2018. 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 Egypt. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

effect of oral amantadine versus gabapentin premedication on laryngoscopy and tracheal intubation on β-endorphins. (time frame: baseline blood sample taken before drug administration and after 15 minutes after intubation and before skin incision). 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 25 Sep 2018.
