The pharmacology, pharmacokinetics, clinical efficacy, adverse effects, interactions, and dosage of nateglinide are reviewed. Nateglinide is an oral hypoglycemic agent approved for use alone or in combination with metformin as an adjunct to diet and exercise for the treatment of type 2 diabetes mellitus. Nateglinide, an amino acid derivative of D-phenylalanine, stimulates the secretion of insulin by binding to the ATP potassium channels in pancreatic beta cells. The result is an increase in beta-cell calcium influx, which leads to rapid, short-lived insulin release. The drug is rapidly and completely absorbed in the small intestine. The estimated bioavailability is 72%. Nateglinide is highly bound to plasma proteins, is metabolized extensively by the liver, and has an elimination half-life of 1.4 hours. Several clinical trials of nateglinide, alone and in combination with other oral hypoglycemic agents, have found the drug to be safe, effective, and well tolerated. The most common adverse effects are nausea, diarrhea, dizziness, and lightheadedness. There is a potential for interactions between nateglinide and medications affected by the cytochrome P-450 isoenzyme system. Dosage regimens ranging from 60 to 240 mg have been evaluated. The maximum effective dosage is 120 mg taken 10 minutes before meals three times a day. Nateglinide is an alternative to second-generation sulfonylureas for the treatment of type 2 diabetes mellitus. Additional comparative trials are needed to fully elucidate nateglinide's role.

The use of plasma-derived products has contributed to a high rate of blood-borne infections among haemophilia patients in China. Recombinant factor VIII (rFVIII) products that are manufactured without human or bovine albumin and include dedicated viral inactivation steps, hold a significant safety advantage over plasma products. However, there is little information published on the use of rFVIII products in non-caucasian populations. This is the first reported evaluation of the efficacy and safety of a rFVIII product in Chinese haemophiliacs. An open-label, non-randomized, prospective, multicentre trial enroled previously treated Chinese patients with haemophilia A. All treatments were administered using a sucrose-formulated rFVIII-FS (Kogenate((R))). Forty-nine patients received totals of 291 infusions (mean, 5.94/patient) and 742 140 IU rFVIII-FS (mean, 2550.3 IU/infusion). Of the 60 acute bleeding episodes that were treated, 90% were successfully managed with only one (81.7%) infusion or two (8.3%) infusions. Physicians reported haemostasis control for acute bleeds to be 'Excellent' or 'Improved' with rFVIII-FS therapy. No FVIII inhibitors were detected in any patient. Only one treatment-related adverse event was reported, which was mild dizziness that resolved spontaneously. rFVIII-FS was efficacious, safe and well tolerated in the treatment of previously treated patients with haemophilia A in China.
