Summary
A moderate restriction of salt intake is recommended as a nonpharmacological approach to reducing high blood pressure, and can be used as an adjuvant to antihypertensive drug treatment. Noncompliance with a salt-restricted diet is the main limitation to this therapeutic approach. Evidence to date has shown that hypertensive patients treated with a calcium antagonist may not require a salt-restricted diet to achieve target blood pressure reductions. Further long term studies are required to confirm this.
