Summary

We have studied the effect of indobufen, a cyclo-oxygenase blocking agent which has proved useful in patients with obstructive vascular disease, on red blood cell (RBC) filterability in vitro and in a pilot study ex vivo.

The addition of indobufen in vitro to blood samples from 10 healthy volunteers did not significantly modify RBC deformability.

We evaluated the ex vivo effect of indobufen (200 mg bd) in 14 patients with obstructive vascular disease. A significant improvement in RBC deformability was noted on the 5th, 14th, and 28th days of treatment, 2 h after the morning dose. Acetylsalicylic acid given to 6 similar patients had no effect suggesting that the positive haemorheological effect of indobufen is probably not linked to its cyclooxygenase blocking effect.
