The data were collected from electronic database together with OPD cards of 76 hypertensive patients during January 2007 to May 2009.
The results revealed that blood pressure of subjects who switched from Felodipine 5 mg to either Amolodipine 5 mg or 10 mg were not significantly different [(SBP=127.38 10.34 mmHg vs. 128.78 13.24 mmHg; p = 0.489), (DBP = 73.73 9.36 mmHg vs. 72.53 10.14 mmHg; p = 0.533)]. Likewise, switching from Felodipine 10 mg to Amlodipine 10 mg or 20 mg resulted in the insignificant difference in blood pressure in any of those subjects [(SBP=126.33 10.45 mmHg vs. 135.33 12.69 mmHg ; p = 0.088), (DBP=69.67 13.99 mmHg vs. 74.80 9.82 mmHg; p = 0.136)].
In conclusion, these results indicated that switching from Felodipine to Amlodipine in patients with hypertension showed the indifferent in blood pressure control. In terms of adverse reactions, peripheral edema was the most frequently problem reported while on Amlodipine.
