Every action within TopVas is logged with a cryptographic hash. This creates an immutable record of what data was validated, when, and by which rule. For industries governed by HIPAA, GDPR, or SOX, this feature alone makes TopVas indispensable.

| Feature | Topvas | Sodium Nitroprusside | Nitroglycerin | |---------|--------|----------------------|----------------| | Onset of action | 2–5 minutes | Immediate (<1 min) | 2–5 minutes | | Duration | 5–15 minutes | 1–2 minutes | 3–5 minutes | | Risk of cyanide toxicity | None | Yes (requires monitoring) | None | | Tolerance development | Low | Moderate | High after 24h | | Effect on heart rate | Mild increase | Reflex tachycardia | Mild decrease | | Need for light protection | No | Yes | No |

• Hypotension (most common): Excessive blood pressure reduction can cause dizziness, syncope, or myocardial ischemia.
• Reflex tachycardia: A compensatory increase in heart rate, particularly if blood pressure drops too quickly.
• Headache: Due to cerebral vasodilation; usually mild and transient.
• Nausea and vomiting: Often avoidable by slowing the infusion rate.
• Injection site reactions: Phlebitis or pain at the IV site; remedied by using a central line for prolonged infusions.
