Frequently asked questions about Paroxetine IR A

What is Paroxetine IR A?

Paroxetine IR A is an immediate-release tablet formulation of paroxetine developed by GSK plc for anxiety disorders. It is a small molecule drug and is also known as Paroxetine IR tablets A. The formulation has been studied in a Phase 1 bioequivalence trial in healthy Chinese subjects.

What is Paroxetine IR A used for?

Paroxetine IR A is being developed for anxiety disorders. The only listed clinical trial enrolled healthy adult volunteers rather than patients, and it was designed as a bioequivalence study comparing tablets manufactured at two GSK sites. No efficacy in patients has been established for this specific formulation.

What does Paroxetine IR A target?

Paroxetine IR A targets SLC6A4, the serotonin transporter. It is classified as an inhibitor of this target. By inhibiting SLC6A4, the drug acts on serotonin reuptake, which is the mechanism associated with its use in anxiety disorders.

Who makes Paroxetine IR A?

Paroxetine IR A is developed by GSK plc, which trades under the ticker GSK. The bioequivalence trial compared immediate-release tablets manufactured at GlaxoSmithKline Tianjin (GSKT) and a Mississauga site, indicating both manufacturing locations are involved in the product.

What phase is Paroxetine IR A in?

Paroxetine IR A is in Phase 1 development. Its single listed trial, NCT03329573, is a completed Phase 1 bioequivalence study. The drug is investigational, and the available information does not indicate that this formulation has received FDA approval.

What clinical trials is Paroxetine IR A in?

Paroxetine IR A has been studied in one clinical trial, NCT03329573, titled a bioequivalence study of paroxetine immediate-release tablets manufactured in GlaxoSmithKline Tianjin (GSKT) and Mississauga sites in healthy Chinese subjects. The Phase 1 trial was completed, enrolled 85 participants, was randomized and controlled, and took place in China.

Is Paroxetine IR A the same as Paroxetine IR tablets A?

Yes, Paroxetine IR A is also known as Paroxetine IR tablets A. Both names refer to the same immediate-release paroxetine tablet formulation developed by GSK plc for anxiety disorders, studied in the Phase 1 bioequivalence trial NCT03329573.
