  • Untoward cutaneous responses to drugs can arise as a result of immunologic or nonimmunologic mechanisms. A variety of adverse reactions result from mechanisms that do not involve an immunologic process. Drug reactions are a public health problem because of their frequent occurrence, occasional severity, and impact on the use of medications. The skin is among the organs most often affected by adverse drug reactions. The list of conditions that can be triggered by medications includes nearly all dermatologic diseases.

  • When a new veterinary medicinal product is launched into widespread use, adverse drug reactions may become apparent. These may be seen in the treated animal patients, in exposed users or as adverse effects on the environment. Additionally, they may manifest as excess residues of the drug in food of animal origin. As a consequence, legislation and regulatory approaches have developed across the globe to address these issues and to ensure that the continued safety of these products can be monitored and, where necessary, that regulatory actions can be pursued to assuage any concerns.

The discipline of pharmacogenetics deals with the importance of the genotype for reactions to drugs. The above forms of hypersensitivity must be distinguished from allergies involving the immune system (p. 72). Lack of selectivity (C).

  • Sulfonamides Antibacterial sulfonamides have a rather high risk of causing cutaneous eruptions and are among the drugs most frequently implicated in SJS and TEN. The combination of sulfamethoxazole and trimethoprim frequently induces adverse cutaneous reactions in patients with AIDS (Chap. 182). Desensitization is often successful in AIDS patients with morbilliform eruptions but is not recommended in AIDS patients who manifested erythroderma or a bullous reaction in response to their earlier sulfonamide exposure.

  • content decreased (Agblevor et al. 1994). The equivalents of chlorine per equivalent of alkali or alkaline earth metals increased from 3.4 to 8.5 during this filtration. This suggests that the residual inorganics may be present as chlorides and that much of the chlorine may be in solution. Chloride ions in solution will have an adverse effect on corrosion of many metals, including stainless steels such as SS304. Compared to coal and many crude oils, biomass has a low sulfur content.
