New asthma drug formulation put to the test in healthy adults
NCT ID NCT07231861
First seen Jun 25, 2026 · Last updated Sep 18, 2026 · Updated 2 times
Summary
This study compares two oral formulations of pranlukast, a drug used for asthma and allergic rhinitis, to see if they are equivalent. Sixty healthy adults will receive a single dose of each version in random order under fasting conditions. The main goal is to measure drug levels in the blood, not to treat any condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pranlukast hydrate
- What this could lead to
- If successful, this study could confirm that the new formulation of pranlukast works the same as the existing one, potentially offering a generic alternative for asthma and allergy treatment.
- What could go wrong
- This is an early Phase 1 trial in healthy volunteers, not patients. It only checks drug levels in the blood, not whether the drug actually helps symptoms. The results may not predict real-world effectiveness.
