Descriptive cross-sectional study on knowledge, awareness and adherence to medication among hypertensive patients in a tertiary care center, Eastern Sri Lanka.

Most of the patients had adequate knowledge on the risk factors and complications of hypertension. But they were unaware about their disease status, and their diagnosis, target organ damage and recent blood pressure values. The drug adherence was reasonably adequate. The main reasons for nonadherence of medication were forgetfulness and expenses.
