Trial Outcomes & Findings for Pharmacokinetic Study of Bupropion Hydrochloride Products With Different Release Patterns (NCT NCT02078180)

NCT ID: NCT02078180

Last Updated: 2017-10-06

Results Overview

Each formulation of buproprion has a different rate of release. Some release the drug immediately while others release the drug slowly. We will compare the exposure of buproprion by formulation and dose by looking at the area under the concentration time curve. The area under the concentration time curve is a mathematical way of looking at drug exposure in the body. The reported values are AUC (0-96 hours).

Participants were randomized to receive one pill each of IR 75, IR 100, SR 100, SR 150, XL 150 and XL 300,in randomized order at six time points. Given the large number of possible sequence combinations, participants are reported as a single Participant Flow Arm with Milestones used to indicate how many participants received each intervention

Measure
Generic Bupropion SR100
n=30 Participants
One oral dose of generic bupropion SR100 generic bupropion: We are comparing different formulations of bupropion that release this drug at different rates. The abbreviation IR75 means immediate release and the number is the dose in mg. The other abbreviations represent SR for sustained-release and XL for extended release, which release the drug slower than the IR formulation.
Generic Bupropion SR150
n=32 Participants
One oral dose of generic bupropion SR150 generic bupropion: We are comparing different formulations of bupropion that release this drug at different rates. The abbreviation IR75 means immediate release and the number is the dose in mg.

SECONDARY outcome

Timeframe: 4 days

Each formulation of buproprion has a different rate of release. Some release the drug immediately while others release the drug slowly. We will compare the exposure of buproprion by formulation and dose by looking at the maximum concentration. The maximum concentration depends on the rate of drug release and so looking at this value can help us compare differences between formulation.
