1. What is a Global RPH Narcotic Calculator?

Definition: This calculator converts opioid doses to their morphine equivalent dose (MED) using standardized conversion factors.

Purpose: It helps healthcare professionals compare the potency of different opioids and calculate equivalent doses for pain management.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Dose\_equiv} \) — Morphine equivalent dose (mg)
• \( \text{Dose} \) — Current opioid dose (mg)
• \( \text{conversion\_factor} \) — Conversion factor to morphine (dimensionless)

Explanation: The current opioid dose is multiplied by its conversion factor to determine the equivalent dose in morphine milligrams.

3. Importance of Opioid Conversion Calculations

Details: Accurate opioid conversion is critical for patient safety when switching medications, preventing overdose, and managing pain effectively.

4. Using the Calculator

Tips: Enter the current opioid dose in milligrams and the appropriate conversion factor. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find conversion factors for specific opioids?
A: Refer to authoritative sources like Global RPH, CDC guidelines, or institutional protocols for approved conversion factors.

Q2: Why convert to morphine equivalents?
A: Morphine is the standard reference opioid for comparing relative potencies of different narcotics.

Q3: Are conversion factors exact?
A: No, they're estimates. Individual patient factors may require dose adjustments.

Q4: Should I use this for opioid-naive patients?
A: This calculator is primarily for converting between opioids in tolerant patients. Consult guidelines for initial dosing.

Q5: Does this account for incomplete cross-tolerance?
A: No, typically reduce calculated dose by 25-50% when switching opioids to account for incomplete cross-tolerance.
