What is the Meaning of Pellet Therapy?

Pellet therapy is a specific method of administering bioidentical hormones, such as testosterone or estradiol, through the subcutaneous implantation of small, custom-compounded pellets. These pellets are designed to dissolve slowly over several months, providing a continuous, steady release of the hormone directly into the bloodstream. This method aims to mimic the body's natural physiological secretion pattern, avoiding the peaks and troughs associated with other delivery methods.

What is the Origin of Pellet Therapy?

The technique of subcutaneous hormone implantation was first developed in the 1930s, utilizing crystalline hormone preparations. Modern pellet therapy has evolved to use bioidentical hormones, which are chemically identical to those produced by the human body. The term 'pellet' refers to the small, solid dosage form that is surgically placed beneath the skin, offering a long-acting delivery system.

What is the Mechanism of Pellet Therapy?

The mechanism of action relies on the dissolution rate of the compressed hormone pellet, which is influenced by the blood flow in the subcutaneous tissue. As the pellet slowly dissolves, the hormone diffuses directly into the systemic circulation at a relatively consistent rate. This steady state delivery bypasses the first-pass metabolism in the liver, potentially offering a more favorable pharmacokinetic profile compared to oral administration.
