Semaglutide: A Comprehensive Overview

Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist, noteworthy for being the first medication of its kind available in both oral and injectable forms[12]. This medication is used for the treatment of type 2 diabetes and as a weight-loss medication.

It works by increasing insulin release, decreasing glucagon secretion, slowing gastric emptying, and reducing appetite[3].

This multifaceted mechanism of action makes semaglutide a valuable tool in addressing the growing obesity epidemic and its associated health risks[4].

Uses of Semaglutide

Semaglutide is primarily used to treat type 2 diabetes. When used in conjunction with diet and exercise, it helps to control blood sugar levels in adults with type 2 diabetes[3].

Semaglutide is also used to lower the risk of major adverse cardiovascular events such as heart attack, stroke, or death in adults with type 2 diabetes and established cardiovascular disease[5].

In addition to its use in treating type 2 diabetes, semaglutide is also approved for chronic weight management and medical weight loss in adults with obesity or overweight with at least one weight-related condition such as high blood pressure, type 2 diabetes, or high cholesterol[3].

It is used together with a reduced-calorie diet and increased physical activity to help people lose weight and keep the weight off[6].

Benefits of Semaglutide

Semaglutide offers several benefits beyond its primary uses for treating type 2 diabetes and weight management. These benefits include:

• Cardiovascular benefits: Semaglutide has been shown to reduce the risk of major adverse cardiovascular events, such as heart attack, stroke, or death, in adults with type 2 diabetes and established cardiovascular disease[7]. Studies indicate that semaglutide may provide cardiovascular benefits irrespective of starting weight and the amount of weight lost, suggesting potential benefits even for those with mild obesity or those who do not experience significant weight loss[8]. This broader cardiovascular protection may be attributed to positive impacts on blood sugar, blood pressure, or inflammation, in addition to weight reduction.
• Improved glycemic control: Semaglutide helps to improve glycemic control in adults with type 2 diabetes by increasing insulin release and decreasing glucagon secretion[9].
• Weight loss: Semaglutide can help people lose weight and keep it off by reducing appetite and slowing gastric emptying[10]. Clinical trials have shown significant weight loss in individuals using semaglutide, with some studies reporting average weight losses of 14.9% to 17.4% in participants with overweight or obesity without type 2 diabetes[11].
• Anti-inflammatory effects: Emerging evidence suggests that semaglutide may have anti-inflammatory effects, which could provide additional benefits in preventing diabetic complications[12]. In obese patients with type 2 diabetes, semaglutide has shown potential in improving psoriasis and reducing epicardial fat volume and inflammation[9].
• Improved quality of life: Studies have shown that semaglutide can improve health-related quality of life in people with obesity, including improvements in physical function, mobility, and control of eating[13].

Side Effects of Semaglutide

Like all medications, semaglutide can cause side effects. The most common side effects of semaglutide include:

• Nausea
• Vomiting
• Diarrhea
• Constipation
• Abdominal pain
• Headache

While many of these side effects are mild and temporary, it’s important to note that some individuals may experience more serious side effects[4].

These can include pancreatitis, gallbladder problems, kidney problems, low blood sugar (hypoglycemia), changes in vision (for people with type 2 diabetes), and increased heart rate[6].

In some cases, semaglutide may also cause dehydration, especially with severe diarrhea, nausea, and vomiting[14]. It’s crucial to stay hydrated while using this medication.

Semaglutide may increase the risk of developing tumors of the thyroid gland, including medullary thyroid carcinoma (MTC)[2]. Patients should be aware of the symptoms of thyroid tumors, such as a lump or swelling in the neck, hoarseness, difficulty swallowing, or shortness of breath, and should consult their doctor immediately if they experience any of these symptoms.

Furthermore, semaglutide may affect mental health and increase the risk of suicidal thoughts, particularly when used for weight loss[2]. Patients, their families, and caregivers should be vigilant for any changes in mental health, such as new or worsening depression, anxiety, or suicidal ideation, and should seek immediate medical attention if such changes occur.

Semaglutide may also increase the risk of pulmonary aspiration during surgery or procedures that use anesthesia or deep sedation[3]. Patients should inform their healthcare providers about their semaglutide use before undergoing any surgical procedures.

It’s important to note that gastrointestinal side effects may decrease over time as the body adjusts to the medication[15].

Drug Interactions with Semaglutide

Semaglutide may interact with various medications, potentially altering blood sugar levels[14]. Some of the medications that may interact with semaglutide include:

• Alcohol-containing beverages
• Antiviral medications for HIV or AIDS
• Aspirin and aspirin-like medications
• Certain medications for blood pressure, heart disease, and irregular heartbeat
• Female hormones, such as estrogens or progestins, and birth control pills
• Medications for allergies, asthma, cold, or cough
• Medications for depression, anxiety, or psychotic disturbances
• NSAIDs, such as ibuprofen or naproxen
• Steroid medications such as prednisone or cortisone
• Thyroid hormones

This list is not exhaustive, and patients should always inform their healthcare provider about all medications they are taking, including prescription and over-the-counter drugs, as well as herbal supplements.

Contraindications for Semaglutide

Semaglutide should be avoided in individuals with certain medical conditions, including:

• History of medullary thyroid cancer
• History of gallbladder disease
• History of pancreatitis
• Multiple endocrine neoplasia syndrome type 2 (MEN 2) [4]

Patients should discuss their medical history with their healthcare provider to determine if semaglutide is a suitable treatment option for them.

Forms of Semaglutide

Semaglutide is available in two different forms:

Oral Semaglutide

Oral semaglutide is available as a tablet that is taken once daily[1]. It is marketed under the brand name Rybelsus and was the first oral GLP-1 receptor agonist approved for the treatment of type 2 diabetes[16][17]. Oral semaglutide is also being studied for weight loss in clinical trials[18].

Injectable Semaglutide

Injectable semaglutide is available as a solution in a prefilled pen that is injected subcutaneously (under the skin) once a week[2]. It is available under the brand names Ozempic and Wegovy. Ozempic is approved for the treatment of type 2 diabetes, while Wegovy is approved for weight loss[16].

Dosage and Administration of Semaglutide

The dosage and administration of semaglutide vary depending on the form of the medication and the condition being treated.

Oral Semaglutide

For the treatment of type 2 diabetes, the starting dose of oral semaglutide is 3 mg once daily for 30 days[1]. The dose may be increased as needed, but the usual dose is not more than 14 mg once daily. It is important to take oral semaglutide at least 30 minutes before the first food, drink, or other oral medicines of the day with a sip of plain water only.

Injectable Semaglutide

For the treatment of type 2 diabetes, the starting dose of injectable semaglutide is 0.25 mg once weekly for 4 weeks[19]. The dose may be increased to 0.5 mg once weekly after 4 weeks, and then to 1 mg once weekly after at least 4 weeks on the 0.5 mg dose. The maximum recommended dose is 2 mg once weekly.

For weight management, the starting dose of injectable semaglutide is 0.25 mg once weekly for 4 weeks[3]. The dose may be increased every 4 weeks as needed, but the usual dose is not more than 2.4 mg once weekly.

Injectable semaglutide should be injected subcutaneously in the abdomen, thigh, or upper arm. The injection site should be changed with each injection.

For patients with diabetes using semaglutide, it is essential to monitor blood sugar levels regularly, especially before and after meals and at bedtime[14]. This helps to prevent hypoglycemia and allows for appropriate dose adjustments based on blood sugar levels.

Cost and Insurance Coverage of Semaglutide

The cost of semaglutide varies depending on the form of the medication, the dosage, and whether the patient has insurance coverage.
