Warfarin management is complex—not because the math is hard, but because real patients don’t follow perfect dosing patterns. 

Most INR tools focus on isolated calculations, rigid templates, or documentation requirements. ThromboLogic was built differently. It was designed by a clinical pharmacist working in a high-volume anticoagulation clinic, with one goal in mind: support real-world clinical decision-making. 

Built for how clinicians actually think 

ThromboLogic integrates guideline-aligned logic (CHEST, ASH, AHA/ACC) with the flexibility required in day-to-day practice. Instead of forcing weekly averages or fixed schedules, it supports manual 7-day dosing, missed doses, partial holds, and individualized adjustments—because that’s how warfarin is actually managed. 

See the full picture, not just a number 

A live, real-date dosing calendar provides immediate visual context across multiple weeks, making it easier to understand trends, dose changes, and INR response over time. No spreadsheets. No mental math. Just clarity. 

Bridging logic without the guesswork 

ThromboLogic incorporates optional bridging support with warfarin, low-molecular-weight heparin, and fondaparinux, using weight-based dosing and rounding logic that mirrors real clinical workflows. Bridging is presented clearly, intentionally, and only when clinically appropriate. 

From clinical reasoning to patient-ready communication 

Every recommendation is translated into a concise, patient-friendly plan—complete with dosing instructions, follow-up INR timing, and clear rationale—designed to fit on a single printed page or be delivered verbally with confidence. 

Designed by clinicians, not vendors 

There are no black boxes, no proprietary lock-in, and no unnecessary complexity. ThromboLogic is transparent, fast, and clinician-controlled—built to support safe, consistent anticoagulation care without getting in the way. 

In short 

ThromboLogic isn’t just an INR calculator. 
It’s a clinical decision engine for anticoagulation management—designed for the realities of modern practice.
