How do I get my husband's blood pressure down?

He went hospital with hypertension crisis and thankfully managed to get it down to stage 2 after he had calmed down. He went doctors and got prescribed ramipril, 2.5mg dose to take every day. Its been a few days now, we changed our livestyle and reduced his sodium intake a lot, we are eating healthy and cooking nutritious meals with very little salt, plenty of fruit and vegetables and really watching salt intake but his BP is still high, this morning it was stage 3 hypertension. What else can we do? Does he need to go on a higher dose? As we are mainly following a lifestyle change because he doesn't want to be on them for the rest of his life.
