Starlix (Nateglinide)

What Is Starlix (Nateglinide)? 

Starlix, or nateglinide, is an oral medication for treating type 2 diabetes. It belongs to the class of drugs known as meglitinides, which stimulate insulin release from the pancreas. Nateglinide targets the beta cells in the pancreas, prompting them to release insulin in response to a meal. This helps control blood sugar levels by facilitating glucose uptake into cells. It is typically taken before meals to manage post-meal spikes in blood sugar. As with any medication, individuals need to follow their healthcare provider’s instructions and maintain a healthy lifestyle, including proper diet and exercise, while using Starlix.
