Injection Regimen (injection + regimen)
Selected AbstractsUnlocking the opportunity of tight glycaemic controlDIABETES OBESITY & METABOLISM, Issue 2005Innovative delivery of insulin via the lung As the incidence of diabetes reaches epidemic proportions, the use of new, alternative routes of insulin delivery to manage glycaemic control is becoming an ever more active area of research. The high permeability and large surface area of the lung make it an attractive alternative to subcutaneous (SC) insulin injections. This review discusses the technical factors that influence the efficacy of pulmonary drug delivery and describes how an appreciation of these issues has enabled the design of Exubera®, a novel, non-invasive, pulmonary dry-powder human insulin delivery system currently in development by Pfizer and the sanofi-aventis Group in collaboration with Nektar Therapeutics. While clinical trials of this novel aerosol delivery of insulin are still ongoing in patients with diabetes, the results so far suggest it is simple to use and can provide reproducible doses of insulin in therapeutic amounts with only a few inhalations per dose. In addition, it has been shown to be comparable in terms of efficacy and safety to a conventional SC insulin injection regimen. Delivering aerosolized drugs via the lungs avoids the necessity for SC injections and thereby may increase the patient's acceptability of an insulin-based therapeutic regimen. [source] Insulin and glucose profiles during continuous subcutaneous insulin infusion compared with injection of a long-acting insulin in Type 2 diabetes1DIABETIC MEDICINE, Issue 5 2008T. Parkner Abstract Aims To compare insulin and glucose profiles during basal continuous subcutaneous infusion of a rapid-acting insulin analogue and once daily subcutaneous injection of a long-acting insulin analogue in Type 2 diabetes. Methods Twenty-one patients with Type 2 diabetes treated with oral glucose-lowering agents were randomized in this two-period crossover study to an equivalent 24-h dose of continuous subcutaneous infusion of insulin aspart and subsequently once-daily bedtime subcutaneous injection of insulin glargine, or vice versa, for eight consecutive days. Plasma profiles of insulin and glucose were recorded. Results On the last day of each treatment period, the area under the curve (AUC) for glucose was 10% lower on the continuous subcutaneous infusion regimen compared with the insulin injection regimen (P = 0.002). This was accomplished by a flat exogenous insulin infusion profile compared with a peaking profile with injected insulin (AUC was 74% higher after injection compared with pre-injection levels (P = 0.001)). During the last 6 days in each treatment period, the intra-subject variability of exogenous fasting insulin levels in the mornings was 41% lower during insulin infusion compared with insulin injection (P = 0.012). The corresponding intra-subject variability for fasting glucose only showed a tendency to be lower during infusion as compared to the injection regimen (28%; P = 0.104). Thirteen symptomatic-only or minor hypoglycaemic episodes were recorded during the entire infusion period compared with three episodes during the injection period. Conclusions Basal continuous subcutaneous infusion of a rapid-acting insulin analogue improved plasma insulin (more flat insulin profile with a lower variability) and glucose (lower AUC) profiles compared with once-daily subcutaneous injection of a long-acting insulin analogue in Type 2 diabetes. [source] Improved glycaemic control with insulin glargine plus insulin lispro: a multicentre, randomized, cross-over trial in people with Type 1 diabetesDIABETIC MEDICINE, Issue 3 2006S. G. Ashwell Abstract Aims To compare blood glucose control using insulin glargine + insulin lispro with that on NPH insulin + unmodified human insulin in adults with Type 1 diabetes managed with a multiple injection regimen. Methods In this 32-week, five-centre, two-way cross-over study, people with Type 1 diabetes (n = 56, baseline HbA1c 8.0 ± 0.8%) were randomized to evening insulin glargine + mealtime insulin lispro or to NPH insulin (once- or twice-daily) + mealtime unmodified human insulin. Each 16-week period concluded with a 24-h inpatient plasma glucose profile. Results HbA1c was lower with glargine + lispro than with NPH + human insulin [7.5 vs. 8.0%, difference ,0.5 (95% CI ,0.7, ,0.3) %, P < 0.001]. This was confirmed by an 8% lower 24-h plasma glucose area under the curve (AUC) (187 vs. 203 mmol l,1 h,1, P = 0.037), a 24% reduction in plasma glucose AUC > 7.0 mmol/l1 (47 vs. 62 mmol l,1 h,1, P = 0.017) and a 15% lower post-prandial plasma glucose AUC (75 vs. 88 mmol l,1 h,1, P = 0.002). There was no reduction in night-time plasma glucose AUC or increase in plasma glucose area < 3.5 mmol/l. Monthly rate of nocturnal hypoglycaemia was reduced by 44% with glargine + lispro (0.66 vs. 1.18 episodes/month, P < 0.001). Conclusions Compared with NPH insulin + unmodified human insulin, the combination of insulin glargine with a rapid-acting insulin analogue as multiple-injection therapy for Type 1 diabetes improves overall glycaemic control as assessed by HbA1c and 24-h plasma glucose monitoring to a clinically significant degree, together with a reduction in nocturnal hypoglycaemia. [source] Recent developments in the management of postmenopausal osteoporosis with bisphosphonates: enhanced efficacy by enhanced complianceJOURNAL OF INTERNAL MEDICINE, Issue 4 2008S. Boonen Abstract. Bisphosphonates are the current mainstay of treatment for postmenopausal osteoporosis. Although daily oral dosing is effective, it is associated with poor compliance, partly because of the pre and postdose fasting and posture requirements. This negatively impacts treatment outcomes, leading to a reduced clinical benefit. Improved, yet still suboptimal adherence has been noticed with less frequent bisphosphonate dosing e.g. once-weekly and once-monthly oral regimens. The recently approved quarterly intravenous (i.v.) injection regimen of ibandronate and yearly i.v. infusion of zoledronic acid are attractive options in the management of postmenopausal osteoporosis. These regimens may assure quarterly and year long compliance. [source] |
