As of February 2001, there is a new type of insulin available under the name of Lantus (insulin glargine). This product is unique as far as insulins go in that it provides 24-hour continuous insulin release with practically no spike. Especially in combination with Humalog (an extremely short-acting insulin) it is possible to mimic the pancreas' natural insulin secretion pattern almost exactly. However, since Lantus cannot be mixed in a syringe with any other insulin, this therapy requires anywhere from 4 to 7 injections daily.

Lantus is generally injected once a day at bedtime to provide continuous glycemic control, with Humalog being injected 15 minutes prior to or immediately after a meal. This mimics the release of insulin in a functioning pancreas which would be stimulated by the ingestion of carbohydrates. With good compliance (and frequent blood glucose monitoring), this is the insulin regiment that provides the best control after the insulin pump.
