Why is the same molecule approved for one thing in one product and something else in another?

Short answer
Regulators do not approve molecules in the abstract: they approve a specific product for a specific use, based on the studies submitted for that use. So the same molecule can carry one indication in one product and a different one in another, each with its own presentation and label.
In plain English
- Each indication needs its own trials and its own application.
- The studied population and label criteria change between indications.
- An approval for one use does not extend the evidence to other uses.
- Approved presentations and strengths can also differ.
What we know
- Public registers show each product's approved indication and date.
- Approved labels describe the population studied for each indication.
What we don't know yet
- A missing indication does not mean the effect is impossible — it may simply be unstudied or unsubmitted.
- Regulatory status varies by country and changes over time.
