Select the option that best describes your situation.
Dapasmart is a brand name for dapagliflozin, an SGLT2 (sodium‑glucose co‑transporter‑2) inhibitor approved for type2 diabetes, heart failure and chronic kidney disease. If you’ve landed on this page, you probably want to know whether Dapasmart lives up to the hype and how it stacks against other options on the market.
TL;DR - Quick Takeaways
- Dapasmart lowers HbA1c by 0.6‑0.9% and adds proven cardiovascular and renal protection.
- Compared with empagliflozin and canagliflozin, efficacy is similar; safety profiles differ slightly in genital infection rates.
- When paired with metformin, Dapasmart offers a cost‑effective regimen on the Australian PBS.
- Patients with a history of genital infections may prefer ertugliflozin, which shows a marginally lower risk.
- For those needing weight loss or strong GLP‑1 benefits, liraglutide remains the go‑to alternative.
How Dapasmart Works - The Science of SGLT2 Inhibition
Inside the kidney, the SGLT2 protein reabsorbs about 90% of filtered glucose. Dapagliflozin binds to SGLT2 and blocks glucose re‑uptake, causing excess glucose to be excreted in urine. This mechanism yields three core benefits:
- Lower blood glucose without stimulating insulin.
- Modest weight loss (averaging 2‑3kg) from calorie loss.
- Reduced blood pressure due to mild diuresis.
Beyond glucose control, large outcome trials (e.g., DECLARE‑TIMI58) demonstrated a 17% reduction in cardiovascular death or hospitalization for heart failure, and a 45% cut in progression to end‑stage kidney disease.
Head‑to‑Head with Other SGLT2 Inhibitors
Three other SGLT2 drugs dominate the Australian market: Empagliflozin brand name Jardiance, approved in 2014., Canagliflozin brand name Invokana, known for strong renal benefits., and Ertugliflozin brand name Steglatro, noted for a lower genital infection rate.. The table below summarizes the key attributes:
| Generic | Brand | Typical Dose | Cardio Benefit | Renal Benefit | Common Side‑effects |
|---|---|---|---|---|---|
| Dapagliflozin | Dapasmart | 5-10mg daily | 17% ↓ HF hospitalization | 45% ↓ CKD progression | UTI, genital yeast |
| Empagliflozin | Jardiance | 10-25mg daily | 14% ↓ CV death | 38% ↓ CKD progression | UTI, hypotension |
| Canagliflozin | Invokana | 100-300mg daily | 12% ↓ CV events | 39% ↓ CKD progression | UTI, amputations (rare) |
| Ertugliflozin | Steglatro | 5-15mg daily | 15% ↓ HF hospitalization | 40% ↓ CKD progression | Lower genital infections |
In practice, the differences are modest. Choice often hinges on price, formulary status, and patient‑specific tolerability.
How Dapasmart Stacks Up Against Classic Therapies
Older agents such as Metformin a first‑line biguanide that lowers hepatic glucose production. remain the backbone of treatment, but they lack the cardio‑renal shield that SGLT2 inhibitors provide.
Another modern class, GLP‑1 receptor agonists e.g., liraglutide, mimic incretin hormones to boost insulin and promote satiety., achieve greater weight loss (up to 6kg) and stronger HbA1c reductions (up to 1.5%). However, they are injectable, pricier, and don’t consistently reduce heart‑failure admissions, a niche where Dapasmart shines.
For many patients, a combo of metformin plus an SGLT2 inhibitor like Dapasmart offers a sweet spot: oral administration, moderate weight loss, and dual cardio‑renal protection without the injection burden.
Safety Profile - What to Watch For
All SGLT2 drugs share a class‑related risk of genital mycotic infections and urinary tract infections (UTIs). In the DECLARE‑TIMI58 trial, dapagliflozin reported a 5.1% genital infection rate versus 3.9% for empagliflozin. Ertugliflozin has the lowest recorded genital infection incidence (~3%)..
Rare but serious events include:
- Euglycemic diabetic ketoacidosis (DKA) - incidence ~0.1%.
- Acute kidney injury - generally reversible on drug cessation.
- Hypotension - watch in elderly or those on diuretics.
Patients with a history of frequent UTIs or low body weight may need dose adjustment or an alternative agent.
Cost, PBS Listing and Practical Prescribing in Australia
Since 2020, Dapasmart is listed on the Australian Pharmaceutical Benefits Scheme (PBS) for patients with:
- Type2 diabetes with inadequate glycaemic control on metformin ± sulfonylurea.
- Established heart‑failure (NYHAII‑IV) regardless of glycaemic status.
- Chronic kidney disease stage3‑4 with eGFR≥30mL/min/1.73m².
The co‑payment is currently AUD42.00 per prescription, making it comparable to empagliflozin (AUD45) and far cheaper than private‑pay GLP‑1 injectables (>AUD250).
Choosing the Right Therapy - A Simple Decision Tree
- Is the patient already on metformin?
- Yes - add an SGLT2 inhibitor (Dapasmart, empagliflozin, etc.).
- No - start metformin first unless contraindicated (eGFR<30mL/min).
- Does the patient have heart‑failure or CKD?
- Yes - prioritize an SGLT2 inhibitor with proven cardio‑renal data (Dapasmart fits).
- Is weight loss a primary goal?
- Consider GLP‑1 agonist (liraglutide) or add it to SGLT2 if cost permits.
- History of genital infections?
- Consider ertugliflozin or switch to a non‑SGLT2 agent.
Using this flowchart in the clinic can reduce indecision and speed up optimal therapy initiation.

Key Takeaway
If you need a single word to remember, it’s Dapasmart comparison: Dapasmart offers a balanced mix of glucose lowering, heart‑failure protection, and kidney preservation at a PBS‑friendly price, making it a strong contender against its SGLT2 siblings and older oral agents.
Frequently Asked Questions
What is the main advantage of Dapasmart over metformin?
Metformin lowers blood sugar primarily by reducing liver glucose output. Dapasmart adds two unique benefits: it reduces the risk of hospitalization for heart failure and slows chronic kidney disease progression, outcomes metformin does not affect.
Can I use Dapasmart if I have an eGFR of 35 mL/min/1.73m²?
Yes. The approved label allows dapagliflozin down to an eGFR of 30. Below that, the drug’s glucose‑lowering effect wanes, but the renal‑protective signal may still be present. Always discuss dose adjustments with your physician.
How does the safety of Dapasmart compare to empagliflozin?
Both have similar rates of urinary tract infections (~4%). Empagliflozin shows slightly fewer genital yeast infections (≈3.9% vs 5.1% for dapagliflozin). Rare adverse events such as ketoacidosis are comparable across the class.
Is Dapasmart covered for heart‑failure patients without diabetes?
Yes. Since 2022, the Australian PBS lists dapagliflozin for heart‑failure (NYHAII‑IV) regardless of glycaemic status, reflecting the drug’s robust data from the DAPA‑HF trial.
What should I do if I develop a genital infection while on Dapasmart?
Promptly seek medical advice. Most infections respond to a short course of topical or oral antifungals. In some cases, temporary discontinuation of dapagliflozin is recommended, followed by re‑evaluation of risk versus benefit.
