PharmaJS

A small library providing the ability to parse pharmaceutical prescriptions into a JSON object that specifies the medication, dose, route, and dosing interval or infusion parameters. The JSON object has the format:

{
  medicationName: [string],
  route: [string],
  dosing: {
    quantity: {
      scalar: [float], // Scalar amount of drug indicated
      unit: [float] // Multiplier for the drug units (e.g. 0.001 for mg)
    },
    perWeightUnits: [float], // Weight unit multiplier if the drug is dosed by weight
    infusionTime: [float] // Time in seconds over which the quantity of drug is infused
  },
  interval: [integer] // Seconds between doses
}

Installation

npm install pharmajs --save
