From the Guidelines
Glucagon preparations differ significantly in their formulation, administration method, and intended use, with newer ready-to-use formulations like Gvoke and Baqsimi offering advantages over traditional reconstituted powder in terms of ease of administration and rapid correction of hypoglycemia. The main differences among available glucagon preparations include their formulation, with traditional glucagon emergency kits containing lyophilized powder that requires reconstitution prior to injection, and newer preparations like Gvoke (glucagon injection) and Baqsimi (glucagon nasal powder) offering ready-to-use formulations 1. These newer options eliminate reconstitution steps, potentially reducing administration errors and treatment delays during hypoglycemic emergencies.
- The standard dose for adults and children weighing 25kg or more is 1mg, while children under 25kg typically receive 0.5mg.
- Intranasal Baqsimi delivers a fixed 3mg dose regardless of weight.
- All preparations work by stimulating glycogenolysis in the liver to increase blood glucose levels, but their onset of action varies slightly, with nasal and liquid formulations potentially working faster than reconstituted options 1. The choice between preparations often depends on patient preference, dexterity, cost considerations, and the ability of caregivers to administer the medication correctly during an emergency. Newer preparations like intranasal and ready-to-inject glucagon are preferred due to their ease of administration resulting in more rapid correction of hypoglycemia 1. It is essential to consider the individual's insurance coverage and prescribe formulary products whenever possible, as health insurance providers may prefer only select glucagon products 1.

From the Research
Differences in Glucagon Preparations
- The available glucagon preparations have undergone significant changes over the years, with earlier formulations requiring reconstitution of a dry powder with diluent immediately prior to injection 2.
- New formulations, including nasal powder glucagon and liquid-stable glucagon, have become available, offering improved ease of use, efficacy, and safety compared to the original glucagon emergency kit 2, 3.
- Intranasal glucagon has been shown to be effective in treating severe hypoglycemia, with a faster time to treatment success and improved usability compared to injectable glucagon 3.
- The different preparations of glucagon have varying characteristics, such as the need for reconstitution, ease of administration, and potential side effects, which can impact their use in emergency situations 2, 3.
Characteristics of Glucagon Preparations
- Injectable glucagon requires reconstitution with diluent prior to injection, which can be a barrier to use in emergency situations 2, 4.
- Nasal powder glucagon is a ready-to-use formulation that can be administered quickly and easily, making it a more convenient option for treating severe hypoglycemia 3.
- Liquid-stable glucagon is another ready-to-use formulation that offers improved stability and ease of use compared to earlier formulations 2.
Efficacy and Safety of Glucagon Preparations
- Studies have shown that intranasal glucagon is effective in increasing blood glucose levels in patients with diabetes, with a success rate of almost all participants meeting the criteria for success in clinical trials 3.
- The efficacy and safety of glucagon preparations have been evaluated in various studies, with results indicating that they are effective in treating severe hypoglycemia, but may have varying side effects, such as nausea and vomiting 2, 3.
