Dear sir/madam, you can be put on different class antihypertensive drugs to achieve target bp control. Other class drugs like diuretics, calcium channel blockers or alpha blockers depending on your health profile. Presently u are on high dose of ramipril ( ACE inhibitor group ). Please monitor serum electrolytes as it can cause high potassium in blood. Ideally if bp is not coming under control then combination of different class antihypertensives is better option then increasing only one class of drug. Better to consult cardiologist/physician for further need. Hope u find this informative.
