§ 01 — Features
01.

Nine instruments. One scan. One brief.

Every signal that matters — safety, dosing, interactions, formulary — surfaced in parallel and cross-referenced against the literature, the trials registry, and the regulators that ship in your market.

F.01

Safety Signals

Adverse events extracted, classified by severity, and rated by evidence weight — pooled from regulators and the peer-reviewed literature.

FDAmedRxivPMCWHONAFDACSAHPRA
F.02

Rising Signal Detection

Publication velocity tracked at 30 days versus the trailing six-month baseline. New safety concerns flagged before they reach the label.

30-day velocity6-month baseline
F.03

Trial Cross-Reference

Active ClinicalTrials.gov studies pulled in and flagged against open signals — including trials marked for immediate safety review.

ClinicalTrials.gov580K+ trials
F.04

Safety Scorecard

Therapeutic alternatives ranked head-to-head on a single, source-cited score from zero to one hundred — class-aware, indication-aware.

/100 scoreclass-matched
F.05

Drug–Drug Interactions

Severity-ranked pairings with proposed mechanism, expected timing, and clinical management — not a wall of yellow warnings.

F.06

Dosage Calculator

Patient-specific dosing with renal, hepatic, body-surface-area, and weight adjustments — and the citation behind each rule.

F.07

Special Populations

Pregnancy, lactation, geriatric, and paediatric considerations surfaced as first-class flags — with the FDA category and the trial evidence behind it.

F.08

Pharmacogenomics

Gene–drug interactions read against CPIC and PharmGKB — flagged for the metabolisers and HLA variants most likely to matter at the bedside.

CYP2D6CYP2C19HLA-BTPMT
F.09

Africa Formulary

Registration, prequalification, and market availability checked against NAFDAC, SAHPRA, and the WHO list — the data your hospital pharmacy actually uses.

NAFDACSAHPRAWHO PQ
i.

Query

Type a drug, an INN, or paste a list. Add co-medications, renal function, weight, and any flags that matter.

ii.

Scan

Eleven million papers, 225K FDA documents, and live WHO, NAFDAC, and SAHPRA feeds — read in parallel.

iii.

Score

Signals classified, weighted by evidence, and ranked against therapeutic alternatives in the same class.

iv.

Brief

One source-cited clinical brief, exportable as PDF, written for the bedside — not the literature.

A scan that reads like a registrar's note.

One query, one document. Severity on the left, the finding in the middle, the source on the right. No tabs. No PDFs to chase.

Critical
Thyroid C-cell tumour signal under active review — contraindicated in personal or family MTC history.
FDA · medRxiv ×3.5
High
Delayed gastric absorption may prolong warfarin Tmax — monitor INR weekly for 4 weeks after initiation.
PMC · 6 trials
Moderate
Renal-adjusted starting dose 0.25 mg weekly (eGFR <30) — no hepatic adjustment required.
FDA label · CPIC

Tirzepatide scores 70 / 100 vs semaglutide 55 / 100 in matched class — weigh against availability.

§ 03 — From the continent, for the continent

Built for Africa's clinicians first.

A clinician in Lagos, Nairobi, or Accra monitoring drug safety manually checks FDA, WHO, NAFDAC, and SAHPRA across separate browser tabs — and still misses the rising signal. Vigil does it in one scan, cites every source, and writes the brief in the time it takes to read the chart.
