Erivedge is a cancer medication that interferes with the growth of certain cells of the body. This medication may be used to treat basal cell carcinoma that has spread to other parts of the body. Erivedge works by disrupting hedgehog signaling pathway that is normally involved in regulating certain cell processes in adults. The hedgehog signaling pathway becomes abnormally active leading to spread and growth of the cancerous cells n basal carcinoma. Erivedge attaches to a protein called SMO that is involved in activating the hedgehog signaling pathway. By doing this, Erivedge blocks this pathway, slowing down the spread and growth of the cancer cells in basal carcinoma.
