Formula Magistralis

Meaning

Formula Magistralis is a classical term referring to a prescription for a medicine that is compounded by a pharmacist specifically for an individual patient based on a physician’s personalized order. This individualized preparation allows for precise tailoring of dose, dosage form, or the exclusion of non-essential ingredients, such as dyes or preservatives, to meet unique patient needs. In hormonal health, this often applies to bio-identical hormone replacement therapy where standard commercial preparations do not offer the exact concentration or combination required for optimal endocrine balance. It represents the pinnacle of pharmaceutical personalization in clinical care.
