Abstract
BACKGROUND Oral medication for patients with type 2 diabetes mellitus plays an important role in diabetes care and is associated with a high level self-care behavior and self-management. However, poor adherence to diabetes treatment is common which causes severe health complications and increased mortality. Barriers to adherence may consist of complex treatment regimens often along with long-term multi-therapies, side effects due to the medication as well as insufficient, incomprehensible or confusing information or instructions provided by the health care provider. Multidisciplinary approaches can support adherence success and can enable a more effective management of diabetes care. One approach in diabetes care can be the involvement of a pharmacist. The aim was to analyze the effectiveness of adherence-enhancing pharmacist interventions for oral medication in type 2 diabetes mellitus. METHODS A systematic review of randomized controlled trials. The study quality was assessed with the Cochrane risk of bias tool. RESULTS Of 491 hits, six publications were included. Two studies mainly examining educational interventions showed a significant improvement in adherence. Moreover, the quality of the included studies was deficient. CONCLUSION Although pharmacist interventions might potentially improve adherence to type 2 diabetes mellitus medication, high-quality studies are needed to assess effectiveness.

Abstract
INTRODUCTION Insulin has usually been administered subcutaneously in the treatment of diabetes mellitus. Alternative delivery routes of insulin are expected to overcome some limitations, mainly concerned with the possibility of hypoglycemia episodes, weight gain and inadequate post-meal glucose control, in order to lead a better patient compliance. AREAS COVERED This review article covers all the most relevant non-invasive insulin delivery methods under development, respective technology and clinical data available according to their status of development. Special focus is given to the systems with late clinical trial evidences, their achievements and pitfalls. Pulmonary and oral appear to be the most advantageous routes, with regard to the long list of potentially marketed products. EXPERT OPINION Alternative insulin delivery to the subcutaneous administration is more and more close to the success, being fundamental that any optimized technology could overcome the overall low mucosal bioavailability of insulin, mostly due to its early degradation before absorption, inactivation and digestion by proteolytic enzymes and poor permeability across mucosal epithelium because of its high molecular weight and lack of lipophilicity.

Abstract
Diabetes is a chronic disease characterized by inadequate insulin secretion with resulting hyperglycemia. Diabetes complications include both microvascular and macrovascular disease, both of which are affected by optimal diabetes control. Many individuals with diabetes rely on subcutaneous insulin administration by injection or continuous infusion to control glucose levels. Novel routes of insulin administration are an area of interest in the diabetes field, given that insulin injection therapy is burdensome for many patients. This review will discuss pulmonary delivery of insulin via inhalation. The safety of inhaled insulin as well as the efficacy in comparison to subcutaneous insulin in the various populations with diabetes are covered. In addition, the experience and pitfalls that face the development and marketing of inhaled insulin are discussed.

Abstract
AIMS Assessment of the long-term safety and efficacy of liquid inhaled insulin via AERx insulin Diabetes Management System (iDMS) in a basal/bolus treatment regimen of adults with Type 1 diabetes. METHODS Patients were randomized 2 : 1 to prandial inhaled (n = 205) or subcutaneous (s.c.) (n = 99) insulin, plus one/two daily injections of neutral protamine Hagedorn (NPH) insulin for 12 months. The primary endpoints were pulmonary function tests (PFT) and baseline changes in chest X-rays at 12 months. Safety and efficacy assessments were measured at regular intervals. RESULTS PFTs after 12 months were comparable between the groups, except for reduced per cent of predicted carbon monoxide lung diffusing capacity with inhaled insulin (difference: -2.03%, P = 0.04) occurring after the first 3 months and then stabilizing. There were no apparent treatment differences in chest X-rays. Overall risk of hypoglycaemia [risk ratio (RR) 1.02, P = 0.83] and adverse events were comparable between groups. Risk of nocturnal hypoglycaemia was higher in the inhaled group (RR 1.58, P = 0.001). Cough [10% (inhaled); 3% (s.c.)] tended to be mild in nature. Inhaled insulin was non-inferior to s.c. insulin for change in glycated haemoglobin (HbA(1c)) after 12 months [difference 0.18% (CI 95%-0.04; 0.39)]. At trial end, mean laboratory measured fasting plasma glucose was lower in the inhaled group (inhaled 9.2 mmol/l; s.c. 11.7 mmol/l; difference: -2.53 mmol/l, P < 0.001). CONCLUSIONS The safety and efficacy results in this trial were similar to those reported with other inhaled insulins; however, inhaled insulin using AERx iDMS requires further optimization to reduce nocturnal hypoglycaemia before it has comparable safety and efficacy to s.c. insulin aspart.

Abstract
PURPOSE To define and understand patient psychological insulin resistance (PIR) and its impact on diabetes management. METHODS Systematic literature review of peer-refereed journals using the MEDLINE database, including all articles in English from 1985 to 2007. The population included patients with type 1 and type 2 diabetes, insulin naïve, and those currently using insulin. A total of 116 articles were reviewed. RESULTS PIR is impacted by patients' beliefs and knowledge about diabetes and insulin, negative self-perceptions and attitudinal barriers, the fear of side effects and complications from insulin use, as well as lifestyle adaptations, restrictions required by insulin use, and social stigma. These etiological influences, both independently and in combination, constitute a patient's PIR and may result in the reluctance of patients to both initiate and intensify treatment, leading to delayed treatment initiation and compromised glucose control. CONCLUSIONS PIR is complex and multifaceted. It plays an important, although often ignored, role in diabetes management. Assisting health care professionals in better understanding PIR from the patient's perspective should result in improved treatment outcomes. By tailoring treatments to patients' PIR, clinicians may be better able to help their patients begin insulin treatment sooner and improve compliance, thus facilitating target glycemic control.

Abstract
Diabetes is a chronic, debilitating disease that afflicts millions of people worldwide and poor glycemic control in this disease leads to numerous microvascular and macrovascular complications. There is growing evidence that tight glycemic control prevents the development, and delays the progression, of microvascular complications and possibly macrovascular disease in patients with diabetes. All patients with Type 1 diabetes and many patients with Type 2 diabetes require intensive insulin therapy to achieve optimal glucose control. Although subcutaneous insulin therapy is the mainstay of insulin therapy, there are patients who fear needles and often refuse to start insulin therapy despite suboptimal glucose control. In these patients, inhaled insulin represents a non-invasive, painless method to administer intensive insulin treatment. The Novo Nordisk AS AERx iDMS (insulin Diabetes Management System) for inhaled insulin is a novel device that administers an aerosol of liquid insulin into the deep lung with dose adjustments as precise as one subcutaneous unit. Initial pharmacokinetic and pharmacodynamic studies demonstrate that the device delivers liquid insulin in a clear dose-response manner and with a rapid onset of action similar to the fast-acting analog insulins. At present, large, long-term Phase III studies are in progress to document not only the efficacy, but also the safety and feasibility of this device in the treatment of patients with diabetes.

Abstract
Drug delivery strategies for diabetes have included a wide range of scientific and engineering approaches, including molecular design, formulation and device design. Molecular engineering has resulted in modified pharmacokinetics, such as rapid-acting or slow-release analogs of insulin. Long-acting insulin formulations are designed to meet the body's basal needs, whereas rapid-acting insulin formulations are designed to cover mealtime glucose spikes. Furthermore, the discovery of new therapeutic biomolecules, which like insulin need to be injected, will drive the need for more flexible and universally applicable delivery systems. Formulation design, such as particle engineering, can be used to modify pharmacokinetic profiles. In general, suspension formulations of insulin commonly demonstrate reduced solubility and result in sustained release. Similarly, depot injections can result in precipitation of insulin at the site of injection, again resulting in lower solubility and sustained release. Particle engineering also has been applied to pulmonary formulations for delivery to the deep lung. The creation of novel drug delivery methods for the treatment of diabetes should remove barriers to insulin therapy and increase patient acceptance and compliance. Eliminating routine injections with needle-free injectors, insulin pumps, inhalation, buccal sprays, intra-nasal delivery, and transdermal patches may offer increasingly attractive alternatives.

Abstract
BACKGROUND AND METHODS Inhaled insulin has recently emerged as an alternative to subcutaneous insulin administration. One inhaled insulin device, AERx (a registered trademark of Aradigm Corp., Hayward, CA, or its affiliates in the United States and other countries) insulin diabetes management system (iDMS) (Novo Nordisk A/S, Bagsvaerd, Denmark), uses a unique liquid human insulin strip to deliver an aerosol of insulin to the lungs. AERx iDMS enables 1-unit increment dosing, and the device ensures that the insulin dose is released at the optimal point of inhalation for delivery to the lungs. RESULTS Compared with subcutaneous human insulin, the pharmacokinetic and pharmacodynamic profile of inhaled insulin with AERx iDMS is similar, but with a more rapid onset of action. Data from these pharmacokinetic studies have also demonstrated that inhaled insulin dosing with AERx iDMS is as consistent and reproducible as subcutaneous human insulin. CONCLUSIONS In individuals with diabetes, prandial inhaled insulin with AERx iDMS is as effective and well tolerated as subcutaneous prandial human insulin or insulin aspart in terms of glycemic control and overall hypoglycemia. No major safety concerns have been raised with respect to pulmonary function tests. Other clinical studies using AERx iDMS in special populations, such as smokers, people with asthma, or people suffering from upper respiratory tract infections, have provided important information regarding the use of inhaled insulin in these circumstances. Overall, pulmonary insulin delivery with the AERx iDMS device appears to be a promising safe and efficacious alternative to subcutaneous insulin injections.

Abstract
Diabetes affects over 18.2 million individuals in the United States alone. Current therapy to treat type 1 diabetes relies on subcutaneous insulin administration either by injection or continuous infusion. In addition, patients with type 2 diabetes who fail lifestyle intervention and oral therapy require subcutaneous insulin. Optimal injection protocols to achieve tight metabolic control often prove burdensome to patients. Thus, development of pulmonary insulin delivery to supplement and/or replace subcutaneous insulin injections may be an effective alternative, allowing patients to achieve intensive diabetes management. This review will discuss the devices in development for the delivery of inhaled insulin. In addition, the efficacy of inhaled insulin in both type 1 and type 2 diabetic populations will be discussed. Finally, the available safety data with respect to the unique pulmonary effects of inhaled insulin will be covered.

Abstract
Diabetes mellitus is a chronic disease that usually requires multiple insulin injections to achieve adequate glycaemic control. This represents a major cause of reduced compliance to treatment. Consequently, other routes for insulin administration have been explored. During recent years, much progress in the development of inhaled insulin has been made. Inhaled insulin has shown favourable properties, such as a rapid onset of action, improved bioavailability and good tolerability; thereby providing satisfaction and ease of administration. However, long-term safety of inhaled insulin needs to be assessed, and the cost would be higher than injectable insulin. Nasal, oral and transdermal insulins are undergoing early phases of pharmacological development. The purpose of this review is to describe the latest developments in the area of non-invasive routes for insulin delivery.

Abstract
The two most important differences between inhaled and oral therapy are (1) the lungs have evolved to exclude foreign material while the gut has evolved to take in large amounts of foreign material, and (2) even if patients adhere to a treatment regimen (regimen compliance or adherence), they may fail to derive any benefit from using an inhaler due to failure of drug delivery (poor device compliance). In other words: True compliance = regimen compliance x device compliance. Aerosol scientists, building on the observations of those working in the field of industrial hygiene, have developed devices that largely address the challenge of bypassing the lung's defenses, in that current devices generate aerosols that contain a significant proportion of particles in the range of 1-5 microm. These have a relatively high probability of entering the lungs and depositing through impaction and/or sedimentation. The development of delivery systems for systemically acting drugs has led to further refinement. The second issue, that of patient behavior, has, until very recently, received very little attention from those developing devices. Regimen compliance involves taking the medication at the suggested times. Device compliance (using the device optimally) is dependent on competence and contrivance. A patient taking a tablet before rather than after a meal is likely to receive some therapeutic benefit even if the effect is suboptimal. A patient whose device compliance is poor because either they are not competent to use the device or contrive to use it in an ineffective manner may derive little or no benefit even if they are scrupulously adhering to their treatment regimen. Lack of precision in the use of the terms "compliance" and "adherence" has contributed to the failure to build in features that may help address issues relating to patient behavior. The resurgence of interest in developing devices that can be used to deliver potent systemically acting drugs has, out of necessity, led to the development of systems that help minimize the impact of poor competence or contrivance on drug delivery. There are suggestions, that need to be confirmed, that regimen compliance (adherence) can be influenced by providing feedback. In the absence of formal studies, comparison of the high-tech and low-tech approaches to improving device compliance incorporated into novel devices might provide valuable insights into what aspects of feedback are important in the clinical setting.
