Frequently Asked Questions

How do I find recruiting trials for a condition or drug?

`search_trials` accepts a condition, intervention, or keyword, plus status and phase filters. It returns trial summaries with NCT IDs for detailed lookup.

What do I get when I open a trial by NCT ID?

`trial_details` returns the full protocol: study summary, eligibility criteria, age and sex requirements, and trial site locations.

Can I search approved drug listings too?

`drug_products` searches Health Canada's Drug Product Database for brand name, manufacturer, active ingredients, approval status, route of administration, and DIN.

Is this enough to decide whether someone should enroll?

It gives you the trial record and eligibility details, but it is reference data only. Use it to compare options, then confirm fit with the study team or a clinician.
