I Am Having The Worse Time Controlling My Blood Pressure,

I am having the worse time controlling my blood pressure, right now I am taking Linsinopril 20mg x2, Metoprolol tartrate 50 mg 2x, Clonidine 0.1 3x, and now Chlorthalidone25mg1x and still my blood pressure remains 177/100, I also take Potassium Cl Micro 10 meq 3x and Allopurinol300 mg1x. Do you think the combination of meds if not compatible ? I am 64, and only have one kidney, lost the other to renal carcinoma in 1999. Have been on the first three meds for 15 yrs now. Tell me in your professional opinion what my options are, thanks
