Every day, patients are harmed not by their diseases but by the drugs prescribed to treat them. Drug interactions missed. Doses not adjusted for failing kidneys. Opioids accumulating silently. Anticoagulants bleeding unchecked. Prescribing cascades adding pills to treat the side effects of other pills. Sentinel Pharma watches every prescription, every interaction, every lab value — and intervenes before the harm happens.
Adverse drug events are the fourth leading cause of death in hospitalized patients — killing more people than pneumonia, diabetes, or kidney disease. Yet most are preventable. The elderly patient on 14 medications whose new dizziness is actually a drug interaction. The post-surgical patient whose opioid dose was never adjusted for declining renal function. The heart failure patient whose anticoagulant bled into her brain because nobody noticed the CYP450 interaction with her new antibiotic. These are not medical mysteries. They are system failures. Failures of attention, of integration, of the human capacity to hold 14 medications, 37 potential interactions, and 4 organ-function variables in working memory simultaneously.
Sentinel Pharma does what no human pharmacist, physician, or nurse can do alone: it monitors every medication, every interaction, every lab value, every organ function parameter, every dose — continuously, simultaneously, for every patient — and generates actionable, prioritized alerts before the adverse event occurs. Not after. Before.
Sentinel Pharma monitors for every category of medication-related harm simultaneously.
Sentinel Pharma integrates with your EHR, pharmacy system, and laboratory to create a continuous medication safety surveillance layer.
Current DDI alerting systems generate so many low-severity alerts that clinicians override 90% of them — including the critical ones. Sentinel Pharma uses AI to stratify interaction severity based on the specific patient's clinical context: renal function, hepatic status, age, weight, comorbidities, and concurrent medications. The system suppresses theoretical interactions while escalating truly dangerous combinations — reducing alert fatigue while ensuring that the interactions that matter are never ignored.
Most ADEs announce themselves before they become emergencies — through subtle lab value changes, vital sign trends, and clinical documentation patterns. A rising creatinine after starting an NSAID. A dropping platelet count on heparin. A widening INR after adding an antibiotic to warfarin. Sentinel Pharma monitors these signals continuously and generates proactive alerts when trajectories suggest an emerging adverse event — giving clinicians the window to intervene before the patient codes, bleeds, or seizes.
Polypharmacy is not merely the count of medications — it is the cumulative physiological burden they impose. Sentinel Pharma calculates anticholinergic burden scores, sedation risk indices, fall risk contributions, cognitive impairment risk, and Drug Burden Index for every patient in real time. The system identifies patients at highest risk for polypharmacy-related adverse events and generates prioritized deprescribing recommendations — medications that can be safely discontinued, doses that can be reduced, and therapeutic duplications that should be resolved.
When kidneys fail, drug clearance changes dramatically — but prescriptions often don't. Sentinel Pharma continuously monitors GFR, creatinine clearance, and hepatic function markers, cross-referencing each patient's medication list against organ-specific dosing guidelines. When organ function declines below dosing thresholds, the system generates immediate dose adjustment recommendations — specifying the exact dose reduction, interval extension, or drug substitution required. The system also detects nephrotoxic and hepatotoxic medication combinations that accelerate organ damage.
Anticoagulants are the most dangerous medications in common clinical use — responsible for one-third of emergency hospitalizations for adverse drug events. Sentinel Pharma provides continuous anticoagulant safety monitoring: predicting INR trajectories from dietary changes, new medications, and illness patterns; detecting DOAC interactions that increase bleeding risk; monitoring HAS-BLED scores dynamically; alerting to dual antiplatelet/anticoagulant therapy without clear indication; and guiding periprocedural bridging decisions. Every anticoagulated patient receives a continuous, real-time bleeding risk assessment.
Opioid safety requires a level of continuous monitoring that human systems cannot reliably provide. Sentinel Pharma tracks morphine milligram equivalents (MME) across all prescribers, detects concurrent opioid-benzodiazepine-gabapentinoid prescribing ("the triple threat"), monitors for metabolite accumulation in renal impairment (normeperidine, morphine-6-glucuronide), flags dose escalation patterns, and calculates real-time respiratory depression risk using the PRODIGY model. The system also detects potential diversion patterns and multi-prescriber opioid receipt.
The prescribing cascade is insidious: a side effect is mistaken for a new condition, treated with a new drug, which causes its own side effects, treated with another drug. An ACE inhibitor causes a cough → diagnosed as "chronic cough" → prescribed a cough suppressant → causes constipation → prescribed a laxative → causes electrolyte imbalance → prescribed a supplement. Sentinel Pharma detects these cascades in real time by analyzing temporal relationships between new symptoms and recent medication starts, alerting clinicians when a "new diagnosis" may actually be a drug side effect that warrants deprescribing rather than additional prescribing.
Half of all medication errors occur at care transitions — admission, ICU transfer, floor transfer, and discharge. Sentinel Pharma automates medication reconciliation by cross-referencing the patient's home medication list, inpatient medication orders, pharmacy dispensing records, and outpatient prescription history. The system identifies discrepancies — unintentional omissions, duplications, dose changes, and new medications without clear indication — and generates a prioritized reconciliation worklist for the clinical pharmacist. At discharge, the system produces a patient-facing medication summary that explains every change in language the patient can understand.
Results from our deployed medication safety programs.
Sentinel Pharma replaced the hospital's existing DDI alerting system. Low-priority alerts dropped 78%. Clinician alert acceptance rate increased from 11% to 46%. In the first year, the system identified 1,840 clinically significant interactions that would have been buried in alert noise — including 23 that the pharmacy team assessed as potentially life-threatening. The hospital's ADE rate dropped 34%.
Deployed across a geriatric care network managing 12,000 patients averaging 9.2 medications each. The polypharmacy engine identified deprescribing opportunities in 68% of patients. An average of 2.4 medications were safely discontinued per patient. Falls dropped 28%. Polypharmacy-related hospitalizations decreased 34%. Cognitive function scores improved in 22% of patients after anticholinergic burden reduction. Total medication cost savings: $3.8M in year one.
The anticoagulant safety engine was deployed across 3 hospitals with 14,000 anticoagulated patients. INR prediction accuracy enabled proactive dose adjustments 48 hours before out-of-range values. Concurrent warfarin-antibiotic interaction alerts prevented 186 potential bleeding events. Periprocedural bridging protocol compliance increased from 62% to 94%. Major bleeding events dropped 44%. The program was cited by the hospital's malpractice insurer as grounds for a 12% premium reduction.
My mother was on fourteen medications when she was admitted to the hospital last year. Nobody — not her internist, not the hospitalist, not the pharmacist — connected the dots between her new "confusion" and the anticholinergic load of four of her medications. She was almost started on a fifth medication — for dementia. It was a prescribing cascade. I am a physician, and I almost missed it in my own mother. That is why I demanded our health system deploy Sentinel Pharma. No family should go through what mine did.
The alert fatigue solution alone saved us. Our pharmacists were seeing 1,200 DDI alerts per day and overriding 89% of them. They stopped reading them. The critical alerts — the ones that mattered — were invisible in the noise. Sentinel Pharma cut the noise by 78% and made every remaining alert clinically actionable. Our pharmacists went from ignoring the system to trusting it. That is the difference between a checkbox and a safety net.
A 74-year-old patient on warfarin was prescribed ciprofloxacin for a UTI by an outside urgent care. Our system detected the interaction within 90 minutes of the pharmacy claim, predicted her INR would exceed 5.0 within 48 hours, and alerted both her cardiologist and primary care physician. They adjusted her warfarin dose before the INR ever moved. Without that alert, she would have bled. I have no doubt about that.
