Compounding pharmacy

Definition

A compounding pharmacy prepares customized medicines by combining, mixing, or modifying pharmaceutical ingredients according to specific prescriptions from registered medical practitioners. Compounding is distinct from dispensing, which involves providing pre-manufactured medicines. Compounding allows for customization: adjusting doses for individual patients, preparing medicines in forms not commercially available (e.g., converting a tablet to a liquid), combining multiple active ingredients into a single preparation, and preparing medicines when commercial products are unavailable or inappropriate. In Australia, compounding pharmacies are registered with AHPRA and must comply with the Therapeutic Goods Administration's Compounding Standards. Compounding is subject to regulation to ensure quality, sterility, and safety, but the standards are less stringent than standards for industrial pharmaceutical manufacturing. Compounding pharmacies sometimes supply peptides that are not approved as therapeutic goods, labelling them as 'research' or 'not for human consumption,' though supply of unapproved medicines to patients for therapeutic use is not lawful. Compounding pharmacies require clear prescriptions from qualified practitioners and appropriate record-keeping.

Legitimate compounding pharmacies operate under strict standards: they maintain detailed records of compounding activities, test ingredients for quality and purity, use sterile techniques for injectable preparations, and label preparations clearly with contents and storage requirements. The advantage of compounding is flexibility and customization; the disadvantage is lower assurance of quality and consistency compared to pharmaceutical manufacturing. For approved medicines, patients should generally use commercially manufactured products unless there is a specific reason (such as drug allergy to an ingredient in all commercial formulations) to require compounding.

In the context of peptides, compounding pharmacies might legitimately prepare customized peptide preparations for patients under a prescriber's supervision if the prescriber determines that commercial products are unsuitable. However, supply of unapproved peptides through compounding pharmacies for therapeutic purposes is not lawful in Australia. The TGA's position is that compounding must not be used to circumvent therapeutic goods regulations or to supply unapproved medicines for human therapeutic use.
