Insulin aspart flexpen is a pre-filled insulin pen used for the treatment of diabetes [1]. It delivers a rapid-acting form of insulin called insulin aspart, which is designed to start working quickly and last for a shorter duration compared to some other insulins [2].
How does Insulin Aspart Flexpen work?
Insulin aspart is a rapid-acting analog of human insulin [3]. It is chemically modified to be absorbed into the bloodstream faster than regular human insulin. Once in the bloodstream, it works by helping glucose from the blood enter cells for energy, thereby lowering blood glucose levels [2]. The FlexPen delivery system is designed for convenient self-administration of the insulin dose [1].
When is Insulin Aspart Flexpen typically used?
Insulin aspart is generally administered before meals or snacks to manage postprandial (after-meal) blood glucose levels [2]. It is used by adults, adolescents, and children aged two years and older with diabetes mellitus [4]. It can be used alone or in combination with long-acting insulins or other diabetes medications [2].
What is the difference between Insulin Aspart Flexpen and other insulins?
Insulin aspart, as found in the FlexPen, is a rapid-acting insulin. This means it begins to lower blood sugar within approximately 10-20 minutes of injection, reaches its peak effect between 1 to 2 hours, and its duration of action is generally 3-5 hours [2]. This profile differs from short-acting insulins like regular human insulin, which have a slower onset and longer duration, and from intermediate-acting or long-acting insulins that provide basal (background) coverage over many hours [5].
How is Insulin Aspart Flexpen dosed and administered?
The dosage and timing of insulin aspart injections are highly individualized and depend on factors such as blood glucose levels, meal intake, and activity [2]. The FlexPen is a disposable device containing a specific amount of insulin, and it allows patients to dial in their required dose before injecting [1]. It is typically injected subcutaneously into the abdomen, thigh, or upper arm [4].
What are the potential side effects of Insulin Aspart Flexpen?
The most common side effect associated with insulin aspart, including in the FlexPen, is hypoglycemia (low blood sugar) [2]. Other potential side effects can include injection site reactions, lipodystrophy (changes in fat tissue at injection sites), and allergic reactions [4].
When does the patent for Insulin Aspart Flexpen expire?
Information regarding the specific patent expiry dates for Insulin Aspart Flexpen and its formulations can be found through resources like DrugPatentWatch.com [6]. Patent protection is crucial for pharmaceutical manufacturers as it provides market exclusivity, and expiry dates determine when generic or biosimilar versions may become available [7].
Who manufactures Insulin Aspart Flexpen?
Insulin aspart, including in the FlexPen formulation, is manufactured by Novo Nordisk [8]. Novo Nordisk is a global healthcare company focused on diabetes care and other serious chronic diseases [8].
