Starlix (Nateglinide) - Drug Interactions, Contraindications, Overdosage, etc

 
 



DRUG INTERACTIONS

Special Populations

Geriatric: Age did not influence the pharmacokinetic properties of nateglinide. Therefore, no dose adjustments are necessary for elderly patients.

Gender: No clinically significant differences in nateglinide pharmacokinetics were observed between men and women. Therefore, no dose adjustment based on gender is necessary.

Race: Results of a population pharmacokinetic analysis including subjects of Caucasian, Black, and other ethnic origins suggest that race has little influence on the pharmacokinetics of nateglinide.

Renal Impairment: Compared to healthy matched subjects, patients with Type 2 diabetes and moderate-to-severe renal insufficiency (CrCl 15-50 mL/min) not on dialysis displayed similar apparent clearance, AUC, and Cmax. Patients with Type 2 diabetes and renal failure on dialysis exhibited reduced overall drug exposure. However, hemodialysis patients also experienced reductions in plasma protein binding compared to the matched healthy volunteers.

Hepatic Impairment: The peak and total exposure of nateglinide in non-diabetic subjects with mild hepatic insufficiency were increased by 30% compared to matched healthy subjects. Starlix® (nateglinide) should be used with caution in patients with chronic liver disease. (See PRECAUTIONS, Hepatic Impairment.)

OVERDOSAGE

In a clinical study in patients with Type 2 diabetes, Starlix® (nateglinide) was administered in increasing doses up to 720 mg a day for 7 days and there were no clinically significant adverse events reported. There have been no instances of overdose with Starlix in clinical trials. However, an overdose may result in an exaggerated glucose-lowering effect with the development of hypoglycemic symptoms. Hypoglycemic symptoms without loss of consciousness or neurological findings should be treated with oral glucose and adjustments in dosage and/or meal patterns. Severe hypoglycemic reactions with coma, seizure, or other neurological symptoms should be treated with intravenous glucose. As nateglinide is highly protein bound, dialysis is not an efficient means of removing it from the blood.

CONTRAINDICATIONS

Starlix® (nateglinide) is contraindicated in patients with:

  1. Known hypersensitivity to the drug or its inactive ingredients.
  2. Type 1 diabetes.
  3. Diabetic ketoacidosis. This condition should be treated with insulin.
