  • Resumen

  • “I can't stress enough how often I get questions about, ‘Is this the paclitaxel doing this? Is this the docetaxel doing this?’ And coming up with strategies to kind of help get our patients through with supportive care is important. It's a really big opportunity for pharmacists and our nurses to really provide it and help our patients get through and show the knowledge that we have and to help them,” Dane Fritzsche, PharmD, BCOP, oncology informatics pharmacist at the Fred Hutchinson Cancer Center and University of Washington Medicine in Seattle, WA, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology nursing practice at ONS, during a discussion about the plant alkaloid drug class.

The only thing special about alkaloid is that it has to contain at least one nitrogen atom.” TS 1:43 “Plant alkaloids are just alkaloids derived from plants itself, so think like the roots, stems, leaves, bark, and things like that. Each of these agents we'll discuss today are unique, but broadly speaking, all of them are extracted, at least when they were first discovered, from a plant source. And they are typically biosynthesized by these plants for defensive purposes.” TS 2:01 “Broadly speaking, [plant alkaloids] are cell cycle–specific agents. They do, depending on the compound, impact different parts of the cell cycle. Topoisomerase inhibitors is an example, so think irinotecan, which is a topoisomerase I inhibitor. There's topoisomerase II inhibitors, like etoposide being a good example. These impact the S phase in your cell cycle, so the synthesis of the DNA. Topoisomerase kind of helps unwind DNA and stabilize that as it's being replicated.” TS 3:36 “Again, these plant alkaloids kind of fall into your typical chemotherapy side effects, so we’re thinking rapidly dividing cells. Our bone marrow—so is it lowering our red blood cells, our white blood cells, our platelets? And then it can also affect our GI [gastrointestinal] tract, whether it causes diarrhea in some cases; in some other cases, it can actually cause the other way and cause severe constipation. And then a lot of these agents do lead to hair loss.” TS 5:28 “The last thing I want to touch on with paclitaxel is neuropathy, or your pins and needles, tingling in the tips of your hands and toes. That is the most common one. That's a sensory neuropathy. But we also can see motor neuropathies with this agent, where the patients start to struggle with their fine motor skills, like buttoning shirts, using pencils, things like that. This is a cumulative ...
