L-glutamine markedly suppressed the development of the gastric lesions induced by aspirin in pylorus-ligated rats. In non-ligated normal rats, aspirin was absorbed rapidly after administration and was maintained in the blood in high salicylate concentration thereafter. When aspirin was administered in combination with L-glutamine, the absorption of aspirin was at nearly the same level as when a...

Among adults undergoing non-cardiac surgery who are at risk of a myocardial infarction, a long-standing question has been whether these patients should receive aspirin throughout the perioperative period. A large (n = 10,010 patients) international trial (POISE-2) demonstrated that perioperative aspirin did not prevent myocardial infarction, and the result was consistent both for patients who h...

Aspirin-exacerbated respiratory disease (AERD) is a chronic inflammatory disease characterized by chronic rhinosinusitis, nasal polyposis, asthma, and airway reactivity to aspirin and other nonsteroidal antiinflammatory drugs (NSAIDs). For patients who have inadequately controlled rhinosinusitis and/or asthma despite treatment with topical corticosteroids and leukotriene-modifying drugs, aspiri...

Background and Purpose Despite its low efficacy, aspirin is the most widely used drug for secondary stroke prevention. The reasons why stroke recurs while patients are on aspirin are unknown. We have analyzed a series of patients who had recurrent strokes while on aspirin. Methods Out of 2231 consecutive patients who were admitted to the Tel Aviv Medical Center from May 1988 through December 19...

Hypersensitivity to aspirin (acetylsalicylic acid; ASA) is present in 5–10% of asthmatic patients and is associated with chronic rhinosinusitis and nasal polyposis, a syndrome referred to as the aspirin triad. 2 The mechanism of the hypersensitivity reaction to aspirin is not immunological, but may be related to the inhibition of cyclo-oxygenase, an enzyme responsible for prostaglandin synthesi...

Twenty seven aspirin sensitive asthmatic patients were studied to determine the relationship between non-specific bronchial responsiveness to inhaled histamine and the degree of sensitivity to aspirin (aspirin threshold dose). No correlation was found between provocative concentration of histamine (PC20H) and aspirin threshold dose. In 11 patients the influence of aspirin desensitisation on bro...

The development of nitric oxide (NO)- and hydrogen sulfide (H2S)-releasing nonsteroidal anti-inflammatory drugs (NSAIDs) has generated more potent anti-inflammatory drugs with increased safety profiles. A new hybrid molecule incorporating both NO and H2S donors into aspirin (NOSH-aspirin) was recently developed. In the present study, the antinociceptive activity of this novel molecule was compa...
