Drug Therapy in Nasal Allergy

Mechanisms of the Development of Nasal Hyperreactivity in Nasal Allergy

Nasal hyperreactivity in nasal allergy conditions is closely related to allergic inflammation, particularly to infiltration by activated eosinophils in the nasal mucosa, observed 4 to 10 hours after a single antigenic challenge. Repeated antigenic challenge in subjects with nasal allergy enhanced nasal hyperreactivity. On the other hand, various therapies including topical steroids, immunothera...

New allergy drug excipient allergy

Background Because of its rarity, drug excipients allergy is often unsuspected by the doctors. Some times the active drug is blamed and discontinued unnecessarily when the real culprit is drug excipients. This was suspected when patients reported exacerbation of urticaria with anti histaminic which are actually used for treating urticaria. After suspecting drug excipient as the cause of allergy.

Tumour necrosis factor-α in nasal allergy

Tumour necrosis factor-alpha (TNF-alpha) was measured by enzyme-linked immunosorbent assay and eosinophil cationic protein (ECP) by radio-immunoassay to evaluate TNF-alpha in nasal allergy. There was no significant difference either between the mean concentrations of TNF-alpha in nasal secretions from the patients with perennial nasal allergy and those of normal subjects, or between the TNF-alp...

Drug allergy

Allergic drug reactions occur when a drug, usually a low molecular weight molecule, has the ability to stimulate an immune response. This can be done in one of two ways. The first is by binding covalently to a self-protein, to produce a haptenated molecule that can be processed and presented to the adaptive immune system to induce an immune response. Sometimes the drug itself cannot do this but...
