My uncle whose age and weight are 74 years and 69 kg respectively has bp around 170/90 as of now and he started taking cilacar 10 tablet since last 1-2 days (2 times a day morning and night in order to lower it faster) so with that should he go for cataract surgery that is scheduled tomorrow? Ecg and all blood and urine reports are normal. Kindly suggest and normal range of bp for him should be how much? And with this cilacar 10 tablet how fast his bp could reduce to normal? Kindly suggest.
