What is duloxetine 20 mg (composition) made of?
Duloxetine 20 mg is a strength of the active ingredient duloxetine (typically used as duloxetine hydrochloride in marketed products). The tablet/capsule composition also includes inactive ingredients (excipients) such as fillers, binders, and coatings, which can vary by brand and manufacturer.
Is duloxetine 20 mg a tablet or a capsule?
Duloxetine comes in different oral solid forms depending on the specific product (for example, immediate-release vs extended-release formulations). The exact “composition” at the strength level can differ based on whether the product is an extended-release formulation and on the manufacturer’s formulation.
Why does the “composition” differ between brands?
Even at the same strength (20 mg), excipients can change because manufacturers use different tablet/capsule technologies and coating systems. That means the active ingredient (duloxetine) should be the same, but the inactive ingredients (and sometimes release characteristics) can differ.
How to find the exact ingredient list for a specific duloxetine 20 mg product
To get the precise composition for the exact product you have (brand name + country), check the package insert or the “Ingredients” section on the prescription label/medication guide. If you share the brand name and whether it’s delayed/extended release (and your country), the exact ingredient list can be identified from the specific product text.
