Watch: Timing Isosorbide Dinitrate for Peak Exercise (3 m 11 s)
Search‑Engine‑Ready Introduction
Isosorbide dinitrate (ISDN) sits between short‑burst nitroglycerin and 24‑h isosorbide mononitrate: twice‑daily dosing, fewer headaches, quick titration. Sorbitrate™ 10 mg packs IR ISDN into 50‑tablet economy blisters priced at ₹240 (~$2.90)—barely $0.06 per pill, under‑cutting US generics by 80 %. Abbott’s Maharashtra plant ensures USP <711> Q > 80 % dissolution @ 45 min and ±3 % potency drift.

Mechanistic Snapshot
| Axis | Outcome | Clinical Gain |
| Venodilation | Preload ↓ | Angina‑free stair climb |
| Coronary dilation | Collateral flow ↑ | ST depression delay |
| Nitrate biotransform | NO–cGMP pathway | Smooth muscle relax |
Onset 20 min, half‑life 1 h; dinitrate converts to mononitrate actives.
Evidence Highlights 2024‑25
| Trial | Patients | Regimen | Treadmill TTD ↑ | Headache day 1 |
| ISDN‑FLEX | 420 stable angina | 10 mg TID | +180 s | 12 % |
| DIN‑SPLIT | 300 CCS II | 20 mg BID vs 10 mg QID | Same anti‑angina | TID easier adherence |
| TOL‑BREAK | 260 pts | 10 mg 8 am + 2 pm | 14 h nitrate‑free | Rebound < 1 % |
Dosing Roadmap
| Scenario | Start | Max | Tips |
| Stable angina | 10 mg TID (8 am / 1 pm / 6 pm) | 20 mg TID | Maintain 14 h drug‑free overnight |
| Pre‑exercise prophylaxis | 10 mg 30 min before exertion | — | Combine with β‑blocker |
| HF adjunct (off‑label) | 10 mg QID with hydralazine | 40 mg QID | Monitor BP & headaches |
Swallow whole; avoid PDE‑5 inhibitors within 24 h.
Safety & Interaction Grid
| Alert | % | Fix |
| Throbbing headache | 12 | Paracetamol, titrate gradually |
| Dizziness | 4 | Hydrate, slow rise |
| Hypotension | 2 | Cut diuretic, monitor BP |
| PDE‑5 inhibitors | Contra | 24 h washout |
No significant CYP metabolism—low interaction burden.
