Actions and spectrum:Â
When benzylpenicilloyl polylysine comes into contact with reagins (penicilloyl skin sensitizing antibodies), it causes instant wheal and flare-ups that could indicate a higher risk of allergic reactions to penicillin therapy in the future.Â

Pregnancy consideration:Â Â
USFDA pregnancy category: CÂ
Lactation:Â Â
Data about the excretion of the drug into human milk is not knownÂ
Pregnancy category:Â Â
Category A: Studies that were well-controlled and met expectations revealed no risk to the fetus `in either the first or second trimester.Â
Category B: There was a lack of studies on pregnant women and no evidence of risk to the fetus in animal experiments.  Â
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.   Â
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.  Â
Category X: Drugs listed in this category outweigh the risks over benefits. Hence, these categories of drugs need to be avoided by pregnant women.   Â
Category N: There is no data available for the drug under this category
Pharmacology:Â
Pharmacodynamics:Â
To identify immunoglobulin E antibodies in individuals with a history of penicillin allergy, benylpenicilloyl polylysine—penicilloyl bound to polylysine—is utilized as a skin-testing reagent. It is thought to be the primary determinant of penicillin metabolism. Roughly 97% of patients with a negative skin test will tolerate penicillin if benzylpenicilloyl and penicillin G (as the only source of minor determinants) are used in the skin test.Â

Generic Name: benzylpenicillin polylysine Â
Why do we use benzylpenicillin polylysine?Â
Pre-Pen, also known as benzylpenicillinicilloyl polylysine injection solution, is a skin testing antigen reagent used to measure penicillin (benzylpenicillin or penicillin G) sensitization in patients who may be clinically hypersensitive to penicillin.Â
