Study Notes

Compounding

Compounding involves combining or mixing two or more ingredients, including at least one drug or pharmacologically active component, to create a final product in an appropriate form for dosing.
Compounding is practiced primarily by pharmacists, but other healthcare professionals may also practice compounding activities when licensed.
Regulatory authorities in each province/territory oversee compounding activities, which include non-sterile products and specialized products for IV solutions or ophthalmic preparations.

Key Points from Health Canada Policy on Compounding

Compounding is done when there is a therapeutic need or lack of product availability, not solely for economic reasons.
Compounding involves a patient-healthcare professional relationship and is actively regulated, with facility inspections by regulatory authorities.
Risk management processes are in place, and customized therapeutic solutions are developed to improve patient care without duplicating approved drug products.

Recommendations for Pharmacy Managers/Pharmacists/Technicians

Communicate the need for compounding with the prescriber and discuss alternatives.
Compound only when the benefits outweigh potential risks.
Use standardized master formulas, supported by references, rationale for ingredients, and consistent units of measure within systems.
Use commercially available tablets/capsules and utilize software to build in additional checks, input patient weight.
Document on a worksheet, perform an independent double-check, and refer to NAPRA guidelines.
Use unique identifiers for ingredients and follow up with the family.

Clonidine Example

Clonidine tablets can be compounded into a suspension.
Dissolve and dose instructions are provided, along with supporting documentation.

Dosage Forms: Cautions

Consider sound-alike, look-alike drugs (e.g., clobazam vs clonazepam, sulfadiazine vs sulfasalazine, DTaP vs Tdap).
Be cautious when assessing dosage forms for enteral tube administration, ketogenic diet, or short bowel syndrome.

Alterations of Dosage Forms

Consider therapeutics, drug coverage, PK/PD, pharmaceutics, safety, patient acceptance, and feasibility when altering dosage forms.

Dosage Forms Example

For a 2-year-old girl (18 kg) with a UTI, an appropriate dosage form for Cephalexin 250 mg PO q8h might be a liquid formulation.
Consider the patient's needs and feasibility when selecting a dosage form.

Compounding Errors

A 1000-fold error occurred when compounding clonidine in a gummy formulation, leading to hospitalization due to hypotension and bradycardia.
The incident highlights the importance of proper compounding procedures, regulation, and pediatric-specific guidance.
