Randomized Controlled Trial Comparative Study Clinical TrialComparison of three slow-release acetylsalicylic acid preparations in rheumatoid arthritis.
Nine patients suffering from chronic rheumatoid arthritis were each given single doses of 1 g acetylsalicylic acid, in the form of each of the preparations studied: an enteric-coated tablet, a microcrystalline tablet, and a capsule containing enterosoluble granules. Absorption from each preparation was good in all patients. Onset of absorption varied to some degree, but similar salicylate levels were reached within 5 hours with all preparations. In the case of enteric-coated tablets, relatively high salicylate levels persisted 12 hours after dosing, which would seem to permit twice daily dosage, regardless of the total daily dose.
