1. Apparatus for determining potency of a medication, comprising:
- a supply of medication in a container;
a temperature sensor operatively coupled to the container and capable of measuring the temperature of the medication to generate temperature data;
a programmable real time clock;
a controller programmed with medication temperature profile data specific to the medication, wherein the controller integrates temperature data and time data with medication temperature profile data on a continuous basis to generate a potency value for the medication.

Abstract
A temperature sensor coupled to a supply of medication measures the temperature of the medication. A real time clock circuit is programmed with a start date and controller integrated circuitry controls operation of the clock and temperature sensor. The controller is programmed with medication temperature profile data that is specific to the medication. The controller integrates temperature and time data with medication temperature profile data for the medication to calculate an expiration date that corresponds to a potency condition for the medication.

14. A method of determining the potency of a medication, comprising the steps of:
-
(a) monitoring the temperature of the medication over time;
(b) accumulating temperature data generated in step (a);
(c) comparing over time the accumulated temperature data with medication temperature profile data specific to the medication;
(d) calculating over time a potency condition of the medication based on the comparison of the accumulated temperature data with medication temperature profile data; and
(e) if the calculated potency condition equals a predetermined potency threshold, providing an alert of an medication expiration condition. - View Dependent Claims (15, 16)
