Disease background and treatment goals
Type 2 diabetes involves insulin resistance and insufficient insulin activity. Persistent high glucose can affect blood vessels, eyes and kidneys. This background explains why glucose management and prevention of organ complications are related but distinct goals. [W]
How the medicines relate to the condition
Metformin — Glucose control
Reduces glucose production by the liver and helps insulin work. Check kidney suitability and digestive tolerability. [C2]
SGLT2 inhibitors — Glucose control / selected organ protection
Increase urinary glucose removal; selected agents also have cardiovascular or kidney benefits. Benefits and eligibility differ by agent and condition. [C4]
Insulin — Glucose control
Provides insulin when the body needs additional insulin activity. Requires an individualized glucose monitoring plan. [C1]
Understanding selection and combination treatment
Treatment is selected around glucose, kidney and cardiovascular health, tolerability and access. Several classes may be combined; needing another medicine does not automatically mean the first one has failed. Lifestyle support remains part of care. [C1]
Monitoring, risks and reassessment
Keep a record of glucose readings, symptoms and the exact formulation used. Metformin can cause digestive symptoms; kidney problems and acute illness can change prescribing decisions. Ask for an individual plan rather than changing treatment from a single reading. [C2]
Questions for a clinician or pharmacist
1. Which outcome is each medicine targeting?
2. How will kidney function affect the plan?
