Resistant hypertension workup.

Identify and correct pseudoresistance
(i) Perform proper measurements of blood pressure.
(ii) Evaluate white coat hypertension with reliable home or 24-hour blood pressure measurements.
(iii) Evaluate patient adherence and improve it with education, prescription of the least costly effective drug regimen with the fewest potential adverse effects. Prefer once daily fixed-dose combination products.

Lifestyle modifications

(ii) Search for causes of secondary hypertension

Tailor treatment according to patient characteristics using optimal doses of appropriate medications. If all fails refer to hypertension specialist.
