Breaking Bad Habits

The pharmaceutical industry has come up with lots of chemotherapy drugs classified according to the chemical structure, the working principle and the possible associations with other medication. Most drugs are based on chemicals obtained from plants and this very origin or source leaves room to further classification. Don’t be surprised to find a drug classified in more categories, because there are many such cases in the medical world. Medical science and professional competence in the health care realm involves a good knowledge of chemotherapy drugs and their specificity.

Alkylating agents is a first class of chemotherapy drugs worth mentioning. These drugs are pretty damaging to the bone marrow because they damage the DNA to prevent the cancerous cells from reproduction. Lots of cancer cases get treated with this kind of chemotherapy drugs, with the mention that doses are always kept low because of the risk to develop leukemia up to ten years after the cessation of the treatment. The platinum based drugs are sometimes included in the same category because they act in a very similar manner against the disease.

Another category of chemotherapy drugs is the one consisting of antimetabolites. They are prescribed for the treatment of ovary and intestinal cancers, breast tumors and leukemia and their impact is not limited to the DNA but also extends to the RNA too.

The anthracyclines represent another type of chemotherapy drugs being part of the antibiotic group. They work against enzymes that help in DNA replication and they are encountered in a wide variety of cancer treatments.

The category of inhibitors comes next. The topoisomerase inhibitors separate and copy the DNA strands efficiently treating leukemia. With a more natural preponderance because of their herbal origin, mitotic inhibitors prevent the production of proteins necessary for the cancer cells growth. Even so, cancer patients undergo a huge risk with any chemical treatment they follow: these chemotherapy drugs could cause peripheral nerve damage to mention only one of the health threats you may fear.

Last but not least, the corticosteroids represent chemotherapy drugs based on hormones and designed to treat lymphoma, leukemia and myeloma together with other diseases. In addition to reducing the cancer cellular growth, they also have a good impact on the way the body reacts to chemotherapy by preventing nausea, vomiting or other types of allergic reactions. Such medication doesn’t have to serve for cancer chemotherapy purposes exclusively, as there are other diseases that can be fought with it.
