What is Semaglutide?
Semaglutide is a medication that belongs to the class of drugs called glucagon-like peptide-1 receptor agonists (GLP-1-RA). It is used for the treatment of type 2 diabetes mellitus, weight management, and cardiovascular risk [1].
Semaglutide works by mimicking the action of the natural incretin hormone glucagon-like peptide-1 (GLP-1), which is responsible for regulating blood sugar levels [2].
By activating GLP-1 receptors, semaglutide stimulates insulin secretion, reduces the production of glucagon (a hormone that raises blood sugar levels), slows down stomach emptying, and promotes feelings of fullness [2].
In treating type 2 diabetes, semaglutide helps lower blood sugar levels, improve glycemic control, and reduce the risk of cardiovascular events in patients with established cardiovascular disease [3].
In addition to its anti-diabetic effects, semaglutide has also been approved for chronic weight management in adults with obesity or overweight. In late 2022, the FDA also approved semaglutide for the treatment of obesity in pediatric patients aged 12 and older [4].
Semaglutide helps to promote weight loss by reducing appetite, increasing satiety, and supporting overall weight management efforts. The recommended total weekly dose for this indication is 2.4mg, in addition to following a reduced-calorie meal plan and engaging in increased physical activity [4].
Semaglutide is offered in subcutaneous and oral tablet forms. The dosage and administration of subcutaneous semaglutide may differ based on the indication and individual considerations, while the oral form is exclusively approved for diabetes.
Recommended Dosage for Semaglutide
In this section, we set out established semaglutide dosing schedules based on the research objective.
Semaglutide Dose for Weight Loss
The typical adult dosage for weight loss is based on the Wegovy (brand name semaglutide) prescribing guidelines at time of writing. Weeks 1-16 follow an initial dose escalation schedule, while the full dose is reached at week 17 of administration, as follows [5]:
- Weeks 1-4: 0.25mg subcutaneously once weekly.
- Weeks 5-8: 0.5mg subcutaneously once weekly.
- Weeks 9-12: 1mg subcutaneously once weekly.
- Weeks 13-16: 1.7mg subcutaneously once weekly.
- Weeks 17 & beyond: 2.4mg subcutaneously once weekly.
Semaglutide Dose for T2D Management
The typical adult dosage of semaglutide for the treatment of type 2 diabetes is also drawn from the Wegovy prescribing guidelines, but involves significantly lower dosing [5]:
- Initial Dose: Administer 0.25mg subcutaneously once weekly for 4 weeks, then increase to 0.5mg subcutaneously once weekly.
- Titration: In the event that further regulation of glycemic levels is required following a minimum of four weeks at the 0.5mg dosage, consider escalating the dose to 1mg weekly.
- Maintenance Dose: The recommended maintenance dose is between 0.5mg and 1mg/weekly.
- Maximum Dose: The maximum recommended dose is 1mg once weekly.
The typical adult dosage for T2D with semaglutide oral tablets is based on the Rybelsus prescribing guidelines and involves significantly higher dosing, due to the reduced bioavailability of semaglutide oral [6]:
- Initial Dose: 3mg orally once daily for 30 days, then increase to 7mg orally once daily.
- Titration: If further glycemic control is required after at least 30 days on 7mg/daily, the dose may be increased to 14mg orally once daily.
- Maintenance Dose: The recommended maintenance dose is between 7mg and 14mg orally, once daily.
- Maximum Dose: The maximum recommended dose is 14mg/day.
When switching a research subject between subcutaneous semaglutide and oral tablets, consider the following guidelines [5, 6]:
- From oral to subcutaneous: Subjects on 14mg orally once daily may transition to 0.5mg subcutaneously once weekly. Subcutaneous administration should start after the last oral dose.
- From subcutaneous to oral: Subjects receiving 0.5mg subcutaneously once weekly can switch to 7mg or 14mg orally once daily. Oral therapy should begin up to seven days after.
Semaglutide Dose for Cardiovascular Risk
The typical adult dosage for cardiovascular risk reduction is determined based on the specific oral or subcutaneous medication prescribed. Below, we present the typical adult dosages for cardiovascular risk reduction.
Subcutaneous Administration [5]:
- Initial Dose: Administer 0.25mg subcutaneously once weekly for four weeks, then increase to 0.5mg subcutaneously once weekly.
- Titration: In the event that further glycemic control is required following a minimum of four weeks at the 0.5mg dosage, consider escalating the dose to 1mg administered subcutaneously on a weekly basis.
- Maintenance Dose: The recommended maintenance dose is between 0.5mg and 1mg subcutaneously once weekly.
- Maximum Dose: The maximum recommended dose is 1mg/weekly.
Oral Tablets [6]:
- Initial Dose: 3mg orally once daily for 30 days, then increase to 7mg orally once daily.
- Titration: If further glycemic control is required after at least 30 days on 7mg/day, the dose may be increased to 1 mg orally once daily.
- Maintenance Dose: The recommended maintenance dose is between 7mg and 14mg orally once daily.
- Maximum Dose: The maximum recommended dose is 14mg/day.
When administering semaglutide to research subjects, it is important to consider dose adjustments and take necessary precautions [5, 6]:
- Renal Dose Adjustments: No dosage adjustment is recommended for subjects with renal impairment.
- Liver Dose Adjustments: No dosage adjustment is necessary for subjects with liver impairment.
- Dose Adjustments: When semaglutide is combined with an insulin secretagogue (such as a sulfonylurea) or insulin, there is an increased risk of hypoglycemia, including severe hypoglycemia. It may be necessary to reduce the insulin secretagogue or insulin dose to minimize the risk of hypoglycemia.
Semaglutide Dosage Calculator
In this section, we cover the two primary methods of administering semaglutide, which are subcutaneous and orally via tablets. We explore the characteristics, benefits, and considerations associated with each form of administration.
Subcutaneous Semaglutide
The dosage of subcutaneous semaglutide varies depending on the specific condition being treated (refer to the above dosage charts).
The recommended dosing regimen for semaglutide for weight reduction entails initiating treatment with a 0.25mg dose once weekly for the initial four weeks. Following that, the dose is progressively escalated at four-week intervals until reaching a maintenance dose of 2.4mg once weekly [5].
Dosing may be adjusted based on the individual subject’s needs and tolerability.
Semaglutide Oral Tablets
Semaglutide oral tablets are currently approved strictly for treating diabetes and are available in different strengths. The usual starting dose is 3mg once daily for 30 days.
After 30 days, the dosage is increased to 7mg once daily. It's important to follow the specific instructions provided or outlined in the product labeling [6].
Benefits of Semaglutide
In this section, we will provide an overview of the benefits of semaglutide, a drug that has demonstrated safety and effectiveness in a range of indications. We will explore its use in weight loss, diabetes management, and cardiovascular health.
Semaglutide for Type 2 Diabetes
Extensive phase 3 clinical testing has been conducted on both the subcutaneous and oral formulations of semaglutide. The once weekly subcutaneous formulation underwent evaluation in the SUSTAIN program (Semaglutide Unabated Sustainability in Treatment of Type 2 Diabetes), which comprised 13 distinct randomized clinical phase 3a and 3b trials [7].
The SUSTAIN trials encompassed global international studies (SUSTAIN 1 through 10), with three additional trials dedicated to China and Japan [7].
Semaglutide is beneficial as a treatment option for type 2 diabetes:
- Lower Blood Sugar Levels: Semaglutide helps regulate blood sugar levels by increasing insulin secretion and reducing glucagon production, leading to improved glycemic control [7].
- Reduced Risk of Cardiovascular Disease: Studies have shown that semaglutide not only helps manage diabetes but also reduces the risk of major adverse cardiovascular events such as cardiovascular death, non-fatal myocardial infarction, or nonfatal stroke in patients with established cardiovascular disease [8].
Semaglutide for Weight Loss
Semaglutide has been found to be effective in promoting weight loss in overweight and obesity. The following benefits contribute to its weight loss effects:
- Reduced Appetite and Food Cravings: Semaglutide acts on the brain's appetite control centers, leading to decreased cravings for high-calorie foods and appetite overall [3].
- Increased Satiety and Fullness: By slowing down the emptying of the stomach and promoting feelings of fullness, semaglutide helps subjects eat less and avoid overeating [3].
- Lower Body Weight and BMI: Clinical trials have demonstrated significant weight loss among volunteers receiving semaglutide treatment. The reduction in body weight also corresponds to improvements in metabolic parameters such as waist circumference and body mass index (BMI) [8].
Other Potential Semaglutide Benefits
Apart from its primary indications, semaglutide shows potential benefits in other areas:
- Cardiovascular Benefits in Non-diabetics: Semaglutide has demonstrated favorable effects on cardiovascular outcomes in subjects with or without diabetes, indicating its potential for cardiovascular risk reduction in a broader population [9].
- Non-Alcoholic Steatohepatitis (NASH): Research suggests that semaglutide may have a positive impact on non-alcoholic steatohepatitis, a liver disease associated with metabolic syndrome and obesity [9].
- Renal Benefits: Preliminary studies indicate that semaglutide may have renal benefits, including a potential reduction in albuminuria and preservation of kidney function, although further research is needed to establish its efficacy.
Semaglutide Side Effects and Safety
Although the primary objective of GLP-1RA therapy is to reduce blood glucose levels, there is a potential risk of hypoglycemia associated with agents like semaglutide.
Notably, the occurrence of hypoglycemia is generally low due to the glucose-dependent insulin secretion stimulated by GLP-1RA. This mechanism ensures that insulin is released in response to elevated blood glucose levels, reducing the likelihood of hypoglycemic events. [7, 9].
Additionally, it is important to note that the inhibition of glucagon release does not occur during hypoglycemic conditions. Therefore, when using subcutaneous and oral semaglutide alone, the risk of hypoglycemia is minimal [10].
Mild to moderate side effects such as nausea, vomiting, diarrhea, constipation, abdominal pain, and decreased appetite are commonly associated with the use of semaglutide and liraglutide [10].
In most cases, these side effects tend to diminish as the body adjusts to the medication.
Serious Side Effects
While uncommon, it is important to be aware that semaglutide may have serious side effects that demand prompt medical attention. These can include significant gastrointestinal complications like pancreatitis (inflammation of the pancreas) and issues with the gallbladder [11].
Signs of pancreatitis may manifest as intense abdominal pain, accompanied by nausea and vomiting [12].
Additionally, other severe side effects can encompass allergic reactions, thyroid tumors, hypoglycemia (low blood sugar), and kidney problems [13].
Safety Considerations and Contraindications
When used under the supervision of qualified professionals, semaglutide is generally considered safe. However, it is important to be aware of certain safety considerations:
- Semaglutide should not be administered to subjects with a personal or family history of medullary thyroid carcinoma, a form of thyroid cancer [14].
- Additionally, it should not be used in subjects with multiple endocrine neoplasia syndrome type 2, a genetic disorder associated with thyroid cancer [15].
- Semaglutide should not be used in subjects who have previously experienced a serious hypersensitivity reaction to semaglutide or any of its components. It is also contraindicated in individuals with a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2) [16].
- Regarding patients undergoing dialysis, no specific dosage adjustment is recommended. However, it is important to exercise caution when using semaglutide in this population due to limited available data [16].
