For example, patients with diabetes require insulin or oral hypoglycemic drugs, asthma patients require beta-antagonists or corticosteroids, hypertension patients require antihypertensives, heart disease patients need beta-blockers or nitroglycerin preparations, and dialysis patients need potassium-exchanging resins, which is crucial for reducing potassium levels when dialysis access is limited. The gene discussed is INS; the disease is Hypertension.
