Pre-pen - Pharmacology:
Benylpenicilloyl polylysine is penicilloyl bound to polylysine and is considered to be the major determinant of penicillin metabolism; it is used as a skin-testing reagent to detect immunoglobulin E antibodies in people with a history of penicillin allergy. If skin testing using benzylpenicilloyl and penicillin G (as the sole source of minor determinants) is negative, approximately 97% of patients with a negative skin test will tolerate penicillin.
Pre-pen for patients
Skin testing for detection of reagin with specific haptenes is never without risk. Skin testing patients known to be extremely hypersensitive to penicillin should not be done unless there is a very strong medical reason for administering penicillin.
