Pharmaceutical Preparations, also known as dosage forms, are the final physical forms in which a drug substance is compounded for administration to a patient, such as tablets, capsules, injections, creams, or transdermal patches. This stage of manufacturing involves combining the active pharmaceutical ingredient (API) with various excipients to ensure stability, accurate dosing, patient compliance, and optimal bioavailability. For hormonal therapies, the preparation dictates the route of administration and the rate of hormone delivery into the physiological system.
Origin
The term “pharmaceutical” is derived from the Greek pharmakon, meaning drug or medicine, and “preparation” signifies the process of making it ready for use. This concept is central to the field of pharmaceutics, the discipline of designing and manufacturing effective drug delivery systems.
Mechanism
The choice of preparation influences the pharmacokinetic profile; for instance, an injectable preparation bypasses the digestive system for rapid systemic absorption, while a transdermal patch allows for slow, sustained release. Manufacturers must demonstrate that the preparation consistently delivers the intended dose of the hormone, ensuring the predictable endocrine response necessary for effective clinical management.
