Virtually all drugs used by nurses exert their effects at a cellular level. A good example would be synthetic insulin that is used to control the blood sugar levels of patients with diabetes mellitus. Synthetic insulin mimics the naturally produced insulin of the pancreas, stimulating human cells to take up glucose from the blood. Human cells are able to recognise each other using the glycoproteins embedded in their cell membranes; these protein markers can also allow drugs to target specific cell types within the body. To conclude this chapter, we will return to Josie who was recently diagnosed with breast cancer.
