The Evolution of Semaglutide Therapy: Subcutaneous Injection vs. Oral Tablet Formulations


Semaglutide has revolutionized the landscape of diabetes and obesity management with its dual formulations available as subcutaneous injections and oral tablets. These formulations offer diverse options for patients and healthcare providers, each with its own unique benefits and considerations. In this article ¿Cómo funciona semaglutida?, we delve into the evolution of semaglutide therapy, comparing and contrasting its subcutaneous injection and oral tablet formulations across various aspects of treatment.

Mechanisms of Action: Harnessing GLP-1 Receptor Agonism

Semaglutide operates by activating the glucagon-like peptide-1 (GLP-1) receptor, which plays a pivotal role in glucose metabolism and appetite regulation. By mimicking the actions of endogenous GLP-1, semaglutide enhances insulin secretion, suppresses glucagon release, delays gastric emptying, and promotes satiety. Both the subcutaneous injection and oral tablet formulations leverage this mechanism to achieve glycemic control and weight management in patients with diabetes and obesity.

Clinical Applications: Indications and Efficacy Profiles

Both formulations of semaglutide have garnered regulatory approval for the treatment of type 2 diabetes mellitus (T2DM), with the subcutaneous injection also indicated for obesity management. Clinical trials have demonstrated the efficacy of semaglutide in lowering HbA1c levels, reducing body weight, and improving cardiovascular outcomes, highlighting its versatility and effectiveness across diverse patient populations.

Dosing Considerations: Frequency and Convenience

One key distinction between the subcutaneous injection and oral tablet formulations of semaglutide is the dosing frequency. The subcutaneous injection is typically administered once weekly, offering the convenience of less frequent dosing compared to daily administration of the oral tablet. This difference in dosing frequency may influence patient preference and adherence to treatment regimens.

Safety Profiles: Balancing Risks and Benefits

Both formulations of semaglutide have demonstrated favorable safety profiles in clinical trials, with similar adverse event profiles observed between the subcutaneous injection and oral tablet. Gastrointestinal side effects, such as nausea and diarrhea, are among the most commonly reported adverse events with semaglutide therapy. Clinicians should monitor patients closely for these side effects and provide appropriate management strategies as needed.

Pharmacokinetic Properties: Understanding Absorption and Distribution

The pharmacokinetic properties of semaglutide differ between the subcutaneous injection and oral tablet formulations. The subcutaneous injection offers a sustained release of semaglutide, resulting in steady plasma concentrations and a prolonged duration of action. In contrast, the oral tablet undergoes rapid absorption and hepatic metabolism, necessitating daily dosing to maintain therapeutic efficacy.

Patient Preferences: Tailoring Treatment to Individual Needs

Patient preferences play a crucial role in the selection of semaglutide formulations. Factors such as dosing frequency, route of administration, and lifestyle considerations may influence patient preference and adherence to treatment. Shared decision-making between patients and healthcare providers is essential to ensure that treatment regimens align with individual needs and preferences.

Future Directions: Innovations in Semaglutide Therapy

The future of semaglutide therapy holds promise for further innovations and advancements. Ongoing research efforts are exploring novel formulations, delivery systems, and expanded therapeutic indications to enhance the efficacy and convenience of semaglutide therapy. These developments may offer new opportunities for personalized treatment approaches and improved outcomes in patients with diabetes and obesity.


Semaglutide therapy has transformed the management of type 2 diabetes mellitus and obesity, offering patients and healthcare providers innovative options for achieving glycemic control and weight management. The subcutaneous injection and oral tablet formulations of semaglutide each have their own unique characteristics and advantages, providing patients with diverse options for personalized treatment. As research continues to advance, semaglutide therapy remains at the forefront of diabetes and obesity management, paving the way for improved outcomes and enhanced patient care.
