Pharmaceutical compounding is the process of creating customized medications to meet the specific needs of individual patients. This practice allows pharmacists to combine, mix, or alter ingredients to produce a medication that may not be commercially available. Compounding can be essential for patients who require unique dosages, have allergies to certain ingredients, or need medications in a different form, such as liquid instead of a pill. Compounding is performed by licensed pharmacists in specialized facilities, ensuring that the medications are safe and effective. The process follows strict guidelines set by organizations like the United States Pharmacopeia to maintain quality and consistency.
