Abstract
Disclosed herein are soft tissue fillers, for example, dermal and subdermal fillers, based on hyaluronic acids and pharmaceutically acceptable salts thereof. Some of the hyaluronic acid-based compositions can include a therapeutically effective amount of at least one anesthetic agent, for example, lidocaine. Compared to conventional compositions that include lidocaine, some of the hyaluronic acid-based compositions disclosed herein can have an enhanced stability, for example, when subjected to sterilization techniques or when stored for long periods of time. Methods and processes of preparing such compositions are also provided.
