My bp not under control with telma 8o h and prazopress 5 mg and petrilbeta 20 mg. Mostly it varies from 160/100 to 140/90. Most of the tests were done including ct aorta angiogram. All are normal. Cardiologist prescribed fruselac 50 mg half tablet and along 5 mg one tablet. With that the bp has come down to 130/90 to 120/90. Can I continue the same medication. Are they safe drugs.
