Glasdegib Overview
-
Glasdegib is used along with cytarabine as a first treatment for acute myeloid leukemia (AML; a type of cancer that begins in the white blood cells) in people over 75 years of age, or in adults who have other medical conditions and can not be treated with other chemotherapy medications. Glasdegib is in a class of medications called hedgehog pathway inhibitors. It works by blocking the action of a protein that signals cancer cells to multiply. This helps stop or slow the spread of cancer cells.
Tolterodine Overview
-
Tolterodine is used treat overactive bladder (a condition in which the bladder muscles contract uncontrollably and cause frequent urination, urgent need to urinate, and inability to control urination). Tolterodine is in a class of medications called antimuscarinics. It works by relaxing the bladder muscles preventing bladder contraction.
