In a randomised, double-blind, four-way crossover study, 24 healthy volunteers received 240 mg/d pentaerithritol tetranitrate (PETN, CAS 78-11-5), 150 mg/d PETN, 60 mg/d isosorbide mononitrate slow release (ISMN, CAS 16051-77-7) or placebo in each study period for two days. Headache and disability to work were self-rated six times per day; individual measurements were combined to total scores. ISMN caused headaches more frequently (in approx. 90% of volunteers) and more severe (average total score 15.2) and a greater disability (average total score 6.0) than the high or low PETN-dosage (both in approx. 50%, headache score 4.9 or 6.4, disability score 1.1 or 2.1, resp.) and placebo (in approx. 10%, headache 0.8, disability 0), all these differences were statistically significant (p < 0.01, Wilcoxon). The high PETN-dosage showed a non-significant trend to produce fewer systemic side effects than the low PETN-dosage (not vice versa). With ISMN six volunteers prematurely terminated the study period and one volunteer who was replaced withdrew from the entire study due to side effects; all volunteers completed the study periods with the other medications.
