Equine immunology 3: immunopharmacology–anti-inflammatory and antihypersensitivity drugs.

This research article reviews various anti-inflammatory and antihypersensitivity drugs used in equine immunology, discussing their functions, classes, and potential for immunomodulatory pharmacology, specifically focusing on the drug levamisole.

Functional or Physiological Antagonists

• The article starts by exploring functional or physiological antagonists, a group of drugs that obstruct the effects of other drugs or biochemical compounds in the body. These antagonists work by competing for the same receptor sites as their target substances, thereby blocking their effects. Some of the drugs in this category discussed in the paper include sympathomimetic amines, anticholinergic drugs, antihistamine drugs, tryptamine antagonists, and dopamine antagonists.

Selective Pharmacological Inhibitors

• The second category of drugs explored is selective pharmacological inhibitors. These are drugs designed to inhibit specific pathways or processes in the body. The focus here is on how these inhibitors selectively act on their target sites without affecting other parts of the body, reducing the risk of side effects.

Broad Spectrum Anti-Inflammatory Drugs

• Next, the paper analyzes broad-spectrum anti-inflammatory drugs. These drugs, including glucocorticosteroids and non-steroidal anti-inflammatory drugs, are designed to inhibit general inflammation within the body. They are usually deployed when the exact cause of inflammation is unknown or when the inflammation is not limited to a specific area of the body.

Miscellaneous Inhibitors

• The fourth category of compounds explored in the paper are miscellaneous inhibitors, including disodium cromoglycate and diethylcarbamazine citrate. These fall outside the regular classification due to the unique or broad range of pharmacological activity they exhibit.

Immunomodulatory Pharmacology

• Finally, the article discusses the potential for immunomodulatory pharmacology, particularly using levamisole as an example. Immunomodulatory drugs are substances that help adjust the immune response, either stimulating or suppressing it as needed. Levamisole is highlighted as an exemplary drug for further understanding this area due to its potential to modulate the immune system.
