Abstract: Purpose. Development of a stability‐indicating high‐performance liquid chromatography (HPLC) method for pyrimethamine analysis, with subsequent application of that method to assess the 90‐day stability of a pyrimethamine suspension compounded from bulk USP‐grade pyrimethamine powder, is… read more here.
