To put simply, they’re a type of cancer-fighting drug that leads to tissue injury or, severe damage if they escape the vein in which injected or infused. You might confuse them with irritants, but they’re very different from the latter.

Irritants just cause mild swelling, pain, redness, or, burning sensation along the infused vein, but vesicants chemotherapy drugs can result in burning, extreme swelling, peeling, and even tissue death if they’re exposed to skin cells, muscles, or soft tissues surrounding veins.

Not only that these drugs remain in tissues even after initial seepage and keep on damaging tissues, which sometimes worsens over days or weeks.

2.Why vesicant chemotherapy drugs are preferred despite their risks?

Even though they’re normally irritant, some of their forms are considered vesicant at larger doses. As the name indicates, they consist of platinum. This element is the one that attaches to the DNA of neoplastic cells and might induce DNA damage and cell death by the immune system of the body. Cisplatin is vesicant at concentrations ≥0.5 mg/mL.

Alkylating Agents

Alkylating Agents- Picture Courtesy: Sentinel Nurse

You’re spot on. These agents add an alkyl group to the nitrogenous bases of DNA, thus inhibiting two DNA strands from linkage. Consequently, breakage occurs that in turn stops the cell from dividing. Fun fact: alkylating agents were the very first drugs used for treating cancer. Although, they’re effective in every cancer type; however, most commonly prescribed for treating slow-growing cancer, like leukemia or solid tumors.

Vinca Alkaloids
