BACKGROUND Recurrent stroke is a frequent, disabling event after ischemic stroke. This study compared the efficacy and safety of two antiplatelet regimens--aspirin plus extended-release dipyridamole (ASA-ERDP) versus clopidogrel. METHODS In this double-blind, 2-by-2 factorial trial, we randomly assigned patients to receive 25 mg of aspirin plus 200 mg of(More)
BACKGROUND Prolonged lowering of blood pressure after a stroke reduces the risk of recurrent stroke. In addition, inhibition of the renin-angiotensin system in high-risk patients reduces the rate of subsequent cardiovascular events, including stroke. However, the effect of lowering of blood pressure with a renin-angiotensin system inhibitor soon after a(More)
BACKGROUND The treatment of ischaemic stroke with neuroprotective drugs has been unsuccessful, and whether these compounds can be used to reduce disability after recurrent stroke is unknown. The putative neuroprotective effects of antiplatelet compounds and the angiotensin II receptor antagonist telmisartan were investigated in the Prevention Regimen for(More)
The effect of oxitropium bromide on lung mucociliary clearance, pulmonary function and viscoelastic properties of sputum was investigated in 10 asthmatics and 10 chronic bronchitics. A controlled, double-blind, crossover study was performed. Following a baseline (B) measurement the patients were, in a random order, allocated placebo (P) or oxitropium(More)
We attempted to evaluate a course on muscle and joint problems for general practitioners using a practice log diary and a factual test paper, which were completed both before and after the course by the doctors attending. A significant improvement was shown in the group score in the test paper taken after the course (p less than 0.001). Scores in the tests(More)
The effect of the mucolytic drug Sputolosin on the clinical signs of respiratory disease among 28 matched pairs of horses was examined. Compared with the untreated group, the treated group showed a significant decrease in the frequency of coughing and a decreased time to resolution of both cough and nasal discharge. The results indicate that the drug is(More)
