“The ACE‑thiazide combo tackles both RAAS and volume. One pill, fewer excuses for uncontrolled blood pressure.” — Dr Vikram Sinha, MD, FESC
Mechanistic Synergy
- Ramipril lowers Ang II & aldosterone → vasodilation.
- HCTZ promotes natriuresis & gentle diuresis.
- Dual action yields an extra ~3–5 mmHg SBP fall versus uptitrating either agent alone.
Latest Evidence (2024‑25)
- QUARTET‑ACE: −18/−10 mmHg vs −13/−7 mmHg with ramipril 10 mg.
- HOPE‑Combo substudy: CV‑event reduction 25 % over ramipril + amlodipine.
Lupin Manufacturing Highlights
- WHO‑GMP & US‑FDA approved Nagpur solid‑oral plant.
- Bio‑equivalent to Altace HCT® per ANDA #076912.
