GUIDELINE

Approved: September 2006

College Contact: Pharmacy Practice


The Guidelines for Compounding Preparations are not meant to supersede the Standards of Practice but to enhance the area of addressing compounding.


1. Scope

The Working Group to Examine Pharmacy Compounding based these guidelines on the following performance indicators for pharmacists fulfilling this role:

  1. Have accurate knowledge and expertise to compound preparations;
  2. Confirm the need for a compounded product;
  3. Maintain access to contemporary equipment;
  4. Use of quality ingredients;
  5. Appropriate labeling;
  6. Suitable containers for each unique product;
  7. Safe and acceptable storage; and
  8. Documentation to ensure accurate checking, duplicating and tracing.
  9. Adherence with health, safety and environmental practice

The key elements of good compounding include qualified and trained personnel, adequate premises and space, appropriate compounding procedures and instructions, suitable equipment, labels and containers, and accurate documentation.


2. Definitions
2.1 Compounding:

Extemporaneous preparation of products that:

  1. Are considered to be within the professional practice of pharmacy, regulated by provincial regulatory authorities in accordance with guidelines and standards that ensure the quality and safety of pharmaceuticals;
  2. Are prepared pursuant to:
    a. Or in anticipation of, a prescription with an established pharmacist-patient/ patient’s agent-prescriber relationship and;
    b. A consultation between the pharmacist and the patient and/or patient’s agent in which the pharmacist uses their knowledge and expertise within federal and provincial regulations;
  3. Do not circumvent a regulatory process or patent laws; and
  4. Provide a customized therapeutic solution to improve patient care.

2.2 Manufacturing:

Preparation of products:

  1. Are subject to the Food and Drug Act and Regulations, Good Manufacturing Practice guidelines, and inspection by Health Canada;
  2. Require a Drug Identification Number (DIN); and
  3. Are produced by a manufacturer independently of a prescription or consultation between a pharmacist and the patient and/or his/her agent.

3.4 The pharmacist shall gather sufficient information to make knowledgeable decisions regarding the formulation and process of the compounding. Formulations should be accessed from a reputable source. If no formulation is available, a formula shall be completed using the pharmacist’s knowledge in pharmacology, chemistry, and therapeutics.

3.5 The pharmacist shall:

  • Assist patients requiring a compounded item;
  • Counsel individuals on the appropriate use of the compounded product;
  • Determine whether the product shall be compounded in a sterile manner;
  • Ensure the quality and accuracy of the ingredients;
  • Calculate required quantities, dilutions, percentages or other pharmaceutical calculations as required;
  • Be knowledgeable of the purpose of each ingredient in the compound;
  • Recognize the potential for incompatibilities;
  • Determine the equipment needed to compound the product;
  • Prepare the product in a logical, safe and pharmaceutically elegant manner ensuring the safety of personnel; and
  • Document the required information to maintain accurate records.

4. Premises
4.1 The compounding area shall be clean, sanitary, orderly and of sufficient space to perform the compounding activity involved.

4.2 Premises shall permit effective cleaning of all surfaces. Surfaces include floors with no carpets.

4.3 Premises shall prevent contamination of medication and the inadvertent addition of extraneous material to the medication.


5. Equipment
5.1 Equipment used for compounding shall:

  • Be situated in an area conducive to the practice of compounding;
  • Be easily and routinely cleaned to minimize the potential for contamination;
  • Be suitable for the preparation of the desired compound; and
  • Be kept clean, dry and protected from contamination during storage to prevent the addition of extraneous materials.

5.2 Equipment used in the compounding process shall be calibrated on a regularly scheduled basis and documentation showing proof of calibration and servicing shall be maintained in the pharmacy records.


6. Sanitation
6.1 The pharmacy shall have available a written sanitation program to include cleaning requirements for the premises and equipment as well as the safe disposal of consumables pursuant to prevailing environmental guidelines.
