Hi,
First I want to know ur husband's age, Is there Blood pressure problem in his family ie mother, father, brother, sister, uncle, grandparents.
Because in young age episodic
high blood pressure without family history may have some underlying cause for high blood pressure, this is called as
secondary hypertension.
Such patients requires multiple medicine for bloodpressure control.
That's why he require further evaluation like basic
blood test for kidney,
sonography of kidney and abdomen, thyroid function test, test for hormone related causes of high blood pressure like related to
adrenal glands.
Also there is need to evaluate for effect of high blood pressure on eyes, kidneys, heart.
As you asked regarding making tablets half for those on which written as not to cut, basically these tablet are special coating or cover which help in constant slow release of Medicine from tablets after ingestion, after cutting tablet this property of formulation lost, and medicine get released faster than usual this may not have any adverse effects on body.
