Final answer:
Doxorubicin is known for having a high potential risk for an immediate hypersensitivity reaction, especially compared to the other drugs listed, which include cisplatin, dacarbazine, and mercaptopurine.
Step-by-step explanation:
The student has asked about the potential risk for an immediate hypersensitivity reaction among a list of drugs. The drug in question that has a high potential risk for an immediate hypersensitivity reaction is doxorubicin (Adriamycin®). This drug is an antibiotic, and antibiotics, along with agents like bleomycin and etoposide, can sometimes trigger such reactions. Doxorubicin is part of various chemotherapy regimens, including combinations with cyclophosphamide and docetaxel, and is known to potentially cause immediate hypersensitivity reactions in some patients.
