Ozempic (known As Rybelsus) (Semaglutide)

Introduction

Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist approved for the management of type 2 diabetes mellitus (T2DM) and for chronic weight management in adults with obesity or overweight. When formulated as an oral tablet, the medication is marketed under the brand name Rybelsus and is also associated with the injectable brand Ozempic. The tablet is available in three strengths-3 mg, 7 mg, and 14 mg-and is manufactured by Novo Nordisk, a leading global diabetes-care company. In addition to its primary indications, semaglutide is being studied for several other metabolic and cardiovascular conditions, some of which appear in off-label clinical practice.

What is Ozempic (known as Rybelsus)?

Ozempic (known as Rybelsus) is the oral tablet formulation that contains the active compound semaglutide. It belongs to the class of GLP-1 receptor agonists, a group of drugs that mimic the action of the naturally occurring incretin hormone GLP-1. The oral formulation was the first GLP-1 agonist approved for ingestion, expanding access beyond injectable therapy. The medication is produced by Novo Nordisk A/S and is supplied in 3 mg, 7 mg, and 14 mg tablets intended for once-daily administration.

How Ozempic (known as Rybelsus) WorksSemaglutide binds selectively to the GLP-1 receptor on pancreatic β-cells, stimulating glucose-dependent insulin secretion and suppressing glucagon release. This dual action reduces post-prandial glucose excursions while preserving basal insulin levels. In the central nervous system, activation of GLP-1 receptors promotes satiety and slows gastric emptying, contributing to reduced caloric intake and weight loss. Oral semaglutide incorporates an absorption enhancer (SNAC) that transiently increases gastric pH, facilitating transcellular passage of the peptide across the gastric epithelium. After absorption, the drug’s plasma half-life is approximately 1 week, allowing steady-state concentrations with daily dosing.

Conditions Treated with Ozempic (known as Rybelsus)

• Type 2 Diabetes Mellitus (T2DM) - Improves glycaemic control as measured by HbA1c reduction and lowers fasting plasma glucose. Recommended as monotherapy or in combination with other antidiabetic agents.
• Chronic Weight Management - Indicated for adults with a body-mass index (BMI) ≥ 30 kg/m² or ≥ 27 kg/m² with at least one weight-related comorbidity (e.g., hypertension, dyslipidaemia). The drug supports ≥ 5 % body-weight reduction when used with diet and exercise.

Both indications are supported by large, phase III trials (e.g., PIONEER 1-10) that demonstrated statistically significant improvements in glycaemic endpoints and meaningful weight loss compared with placebo or active comparators.

Off-Label and Investigational Uses of Ozempic (known as Rybelsus)

• Prediabetes Prevention - Early-phase studies suggest oral semaglutide may delay progression from impaired glucose tolerance to overt T2DM.
• Non-Alcoholic Fatty Liver Disease (NAFLD) - Small-scale trials report reductions in hepatic steatosis indices, likely secondary to weight loss and improved insulin sensitivity.
• Cardiovascular Risk Reduction - Although the injectable Ozempic has an FDA-approved label for reducing major adverse cardiovascular events (MACE) in T2DM, the oral formulation is being investigated in cardiovascular outcome trials (CVOTs) for similar benefits.

These applications are not approved by the FDA, EMA, or other regulatory bodies. Use for any off-label purpose should occur only under direct supervision of a qualified healthcare provider, with careful monitoring of efficacy and safety.

Is Ozempic (known as Rybelsus) the Right Medication for You?

Suitable patients include adults with:

• Established T2DM who require additional glycaemic control beyond metformin or other oral agents.
• A BMI ≥ 30 kg/m² (or ≥ 27 kg/m² with comorbidities) seeking medically supervised weight reduction.

Clinical scenarios where oral semaglutide is especially valuable:

• Patients who prefer a non-injectable regimen.
• Individuals with limited injection site access (e.g., severe arthropathy).

Contraindications and cautions:

• Personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia type 2 (MEN 2).
• Prior severe hypersensitivity to semaglutide or any tablet excipient.
• Pregnancy, lactation, or planned conception (use only if benefits outweigh potential risks).
• Severe gastrointestinal disease (e.g., gastroparesis) may exacerbate nausea or vomiting.

Risks, Side Effects, and Interactions

Common

• Nausea
• Diarrhoea
• Decreased appetite
• Abdominal discomfort

These events usually appear during the first weeks of therapy and often diminish with continued use.

Rare

• Acute pancreatitis (characterised by epigastric pain radiating).
• Gallbladder disease (e.g., cholelithiasis).

Patients should seek prompt medical evaluation if symptoms develop.

Serious

• Severe hypersensitivity reactions, including anaphylaxis.
• Thyroid C-cell tumours (observed in rodent studies; relevance to humans is uncertain but warrants caution).

Drug-Drug Interactions

• Insulin or sulfonylureas - May increase risk of hypoglycaemia; dose adjustment often required.
• Oral contraceptives - No clinically significant interaction reported, but adherence to dosing schedule is essential.
• Warfarin - No documented interaction, yet routine INR monitoring is advisable when initiating or discontinuing semaglutide.

Drug-Food Interactions

• Tablet must be taken on an empty stomach with ≤ 120 mL of water, at least 30 minutes before the first food, beverage, or other oral medication of the day.
• High-fat meals may reduce absorption and blunt therapeutic effect.

Use: Dosing, Missed Dose, Overdose

• Initial dose: 3 mg orally once daily for 30 days, primarily to improve gastrointestinal tolerance.
• Maintenance dose: Escalate to 7 mg once daily; if additional glycaemic control is needed, increase to 14 mg after at least 30 days on 7 mg.
• Missed dose: Take the forgotten tablet as soon as remembered, provided at least 30 minutes remain before the next scheduled dose. If the next dose is within 30 minutes, skip the missed tablet and continue with the regular schedule. Do not double-dose.
• Overdose: Excessive ingestion may intensify gastrointestinal symptoms and hypoglycaemia (especially with concomitant sulfonylureas). Patients should contact emergency services or a poison-control centre promptly.

Practical precautions

• Avoid alcohol excess, as it may worsen nausea and increase hypoglycaemia risk when with other glucose-lowering agents.
• Do not operate heavy machinery until the individual’s response to the medication is known, particularly during the titration phase when dizziness or fatigue may occur.

FAQ

• Can I travel internationally with Ozempic (known as Rybelsus) tablets?

  • Yes. Keep the medication in its original labelled container, store it at room temperature (≤ 30 °C), and carry a copy of the prescription or a physician’s letter if required by customs authorities.

• What should I do if the tablet dissolves partially in water?

  • The tablet must be swallowed whole with a small amount of water. If it disintegrates before swallowing, discard it and take a new tablet with the proper amount of water.

• Does the tablet contain any allergens such as gluten or lactose?

  • The inactive ingredients include microcrystalline cellulose, calcium stearate, and sodium lauryl sulphate; it does not contain gluten, lactose, or soy protein.

• How long can I store the tablets in a hot climate (e.g., > 30 °C)?

  • Prolonged exposure to temperatures above 30 °C may degrade the active ingredient. Store the product in a cool, dry place and avoid direct sunlight; use a temperature-controlled container if necessary.

• Is it safe to take Ozempic (known as Rybelsus) with caffeine?

  • Caffeine has no known pharmacokinetic interaction with semaglutide. However, excessive caffeine may exacerbate gastrointestinal side effects such as nausea.

• What is the difference between oral semaglutide and the injectable version?

  • Both formulations contain the same active molecule but differ in absorption mechanisms. The oral tablet uses an absorption enhancer (SNAC) and must be taken on an empty stomach, whereas the injectable bypasses the gastrointestinal tract and is administered weekly.

• Can I split or crush the tablet to adjust the dose?

  • No. The tablet is not designed for splitting or crushing; doing so may alter the absorption profile and reduce efficacy.

• Will taking this medication affect routine blood tests?

  • Semaglutide may modestly lower fasting glucose and HbA1c values, which will be reflected in laboratory results. It does not interfere with coagulation panels, liver enzymes, or renal function tests.

• Is there a specific time of day that works best for taking the tablet?

  • The tablet should be taken in the morning, at least 30 minutes before eating, drinking (other than water), or other oral medications, to maximise absorption.

• How does the drug’s half-life influence dosing frequency?

  • Despite a plasma half-life of about one week, the drug’s pharmacodynamics require daily dosing to maintain consistent GLP-1 receptor activation and steady glycaemic control.
