Allergy mediated by selective IgE to certain types of NSAIDs by which symptoms are caused exclusively by a specific group of NSAIDs and no cross-reactivity exists with the other groups of anti-inflammatories. In a study carried out with 26 methimazole-allergic patients with IgE-mediated reactions [33], 14 of which developed anaphylaxis, BAT showed a sensitivity of 42% with an optimum specificity of 100%. No other validated in vitro test exists to date for the diagnosis of this disorder and so it represents an essential aid to diagnosis.

Cardiovascular Keep doses of NSAIDs and glucocorticoids low, consider initiation of folic acid to reduce homocysteine level elevations induced by methotrexate, consider initiation of low-dose aspirin and/or HMG-CoA reductase inhibitors (statins), and encourage smokers to discontinue tobacco use and assist with the development of a tobacco-cessation plan.11,12... 

At equipotent doses, the analgesic and anti-inflammatory activity of all NSAIDs and aspirin are similar. The selection of a specific NSAID should be based on tolerability, previous response, and cost. Some patients respond to one NSAID better than to another. If an insufficient response is achieved with one NSAID, another agent from the same or a different chemical class should be tried. Pain relief occurs rapidly (within hours), but antiinflammatory benefits are not realized until after 2 to 3 weeks of continuous therapy. This period is the minimal duration that should be considered an adequate NSAID trial. 

The group C counterirritants methyl nicotinate and histamine dihydrochloride produce vasodilation.24 Methyl nicotinate is a nicotinic acid derivative that produces prostaglandin-mediated vasodilation.46 NSAIDs and aspirin block the production of prostaglandins and decrease methyl nicotinate-induced vasodilation. Application over a large area has been reported to cause systemic symptoms and syncope, possibly due to vasodilation and a decrease in blood pressure.47 Patients should be educated to apply only scant amounts to the affected area to avoid this effect. 

Dietary and pharmacologic agents influence the risk of colon cancer. Diets high in fat and low in fiber are associated with increased colon cancer risk, whereas the regular use of aspirin (and other NSAIDs) and calcium supplementation may decrease the risk of colon cancer. 

Nonnarcotic analgesics. The nonnarcotic analgesics include aspirin, NSAIDs, and acetaminophen. Aspirin acts centrally and peripherally to block the transmission of pain impulses. Furthermore, it reduces fever and inflammation and inhibits synthesis of the prostaglandins that increase the sensitivity of nociceptors. 

The efficacy and safety of cyclooxygenase-2 (COX-2) selective inhibitors (e.g., celecoxib) have not been fully assessed in gouty arthritis, but they are more costly than conventional NSAIDs and are unlikely to result in fewer GI complications because of the short duration of therapy. 

Nonsteroidal antiinflammatory drugs (NSAIDs) and/or corticosteroids may be used for symptomatic relief if needed. They provide relatively rapid improvement compared with DMARDs, which may take weeks to months before benefit is seen. However, NSAIDs have no impact on disease progression, and corticosteroids have the potential for long-term complications.

Drugs most commonly used for acute tocolysis include magnesium sulfate, -adrenergic agonists, NSAIDs, and calcium channel blockers. 

High-dose NSAIDs and the combination of aspirin or acetaminophen with butalbital or, rarely, codeine, are effective options. The use of butalbital and codeine combinations should be avoided when possible. 

Considering all aspects, sex hormones, antibacterials, and antineoplastic agents were identified by Christensen as the three most relevant groups of chemicals concerning their potential human risk as a consequence of drug exposure via the environment [10]. Immunochemical methods for hormones and antibiotics have already been discussed above. In this section we will describe methods based on the use of antibodies for the analysis of analgesics, NSAIDs, and cytostatic agents.
