Text: This was reflected by a significant increase in the amplitude of oesophageal body contractions (change from pre - to 1 h post-injection : sumatriptan 9. 9 (2. 8, 17. 1) mmHg vs. placebo -0. 8 (-4. 2, 2. 6) mmHg, difference 10. 8 (4. 4, 17. 1) mmHg ; P = 0. 003) and a transient increase in lower oesophageal sphincter pressure (change from pre - to 5 min post-injection : sumatriptan 10. 9 (5. 2, 16. 6) mmHg vs. placebo 5. 1 (1. 8, 8. 4) mmHg, difference 5. 8 (-0. 7, 12. 3) mmHg ; P = 0. 08).
