Abstract
Since the first use of insulin 100 years ago, there have been marked improvements in diabetes therapy including, but not limited to, the development of oral antidiabetic agents (OADs), incretin mimetics and insulin analogues. Still, there are substantial shortcomings in diabetes therapy: the blood-glucose lowering effect of OADs is often limited, incretin mimetics often induce gastrointestinal side effects and insulins still induce hypoglycaemia and weight gain in many patients.
This review evaluates on-going developments of antidiabetic drugs for their potential for future therapy focussing on injectable therapies. Recent data from dual agonists, in particular tirzepatide, a combination of GIP- and GLP-1 receptor agonists, show unprecedented reductions in HbA1c, body weight and cardiovascular risk factors. Once-weekly administrations of incretin mimetics open up the potential of a combination with once-weekly insulins that have been shown to have low peak-to-trough fluctuations. Eventually, it might be feasible to administer incretins and insulins (combinations) orally. While this has already been achieved for incretins, there are still some challenges for the oral application of insulin. Nevertheless, many promising data of novel antidiabetic drugs clearly indicate that therapy of people with diabetes will become easier, safer and more efficacious in the next years.
