Clinical Information for Healthcare Professionals

Mechanism of Action

Rybelsus (oral semaglutide) is a GLP-1 receptor agonist that enhances glucose-dependent insulin secretion, suppresses glucagon secretion, and delays gastric emptying. This leads to improved glycemic control and potential weight loss in patients with type 2 diabetes.

Pharmacokinetics and Dosing

The recommended starting dose is 3 mg once daily, taken on an empty stomach at least 30 minutes before the first food, beverage, or other medications of the day. After 30 days, the dose may be increased to 7 mg, with a maximum of 14 mg. Oral bioavailability is approximately 1%, but the absorption window is optimized by fasting conditions.

Clinical Trial Data

Rybelsus has been evaluated in several clinical studies, including the PIONEER trial program. These trials have shown statistically significant reductions in HbA1c levels and body weight compared to placebo and some active comparators. The efficacy and safety were sustained over long-term use in various patient populations.

Indications and Usage

Rybelsus is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes. It is not indicated for use in patients with type 1 diabetes mellitus or for the treatment of diabetic ketoacidosis.

Contraindications

  • Personal or family history of medullary thyroid carcinoma (MTC)
  • Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
  • Hypersensitivity to semaglutide or any of its components

Warnings and Precautions

  • Risk of thyroid C-cell tumors: monitor for symptoms such as neck mass, hoarseness, dysphagia.
  • Pancreatitis: consider discontinuation if suspected.
  • Acute kidney injury: monitor renal function especially in patients experiencing severe gastrointestinal reactions.
  • Hypoglycemia: when used in combination with insulin or sulfonylureas.

Drug Interactions

Due to delayed gastric emptying, Rybelsus may affect the absorption of orally administered medications. Caution is advised when co-administering with drugs that require fast gastrointestinal absorption.

Patient Counseling Information

Healthcare professionals should educate patients on proper administration timing, potential side effects, and the importance of adherence. Patients should be informed about possible gastrointestinal symptoms and the need for gradual dose escalation.
