Issues in contemporary drug delivery. Part IV. Insulin therapy

Continuous insulin infusions are a valuable way of managing highly selected patients, although patients and healthcare practitioners must be aware of the limits and the increased risks involved with this type of technology. Maximum benefit from the CSII technology is achieved when the patient is part of a complete healthcare team accessible on a daily basis to respond to the changing nature of the underlying diabetes. Intranasal and pulmonary delivery of insulin, in contrast, represent a minor technology that will potentially add convenience to some diabetic management plans and possibly provide a new treatment approach for noninsulin-dependent diabetic patients.
