sustained-release implants

sustained-release implants

Sustained-release implants are small devices placed in or near the body that release a medicine slowly over weeks, months, or even longer. They are designed to provide a steady dose of drug without the need for frequent daily administration, such as eye drops or pills. In eye care, these implants can be inserted into the eye or surrounding tissues to target diseases directly and reduce exposure elsewhere in the body. Materials used include biodegradable polymers that dissolve over time and non-degradable reservoirs that may be removed or refilled. The main advantages are improved adherence, consistent drug levels, and often fewer side effects compared with repeated dosing. This can be especially helpful for people who struggle with daily medications, have limited dexterity, or need long-term therapy. However, implants also carry risks like infection, inflammation, mechanical problems, or the need for surgical placement and follow-up. Decisions about using an implant weigh these risks against the benefits of more reliable treatment and preserved vision or health. As technology improves, sustained-release implants are becoming an important option for managing chronic conditions by simplifying care and improving outcomes.
