• Cardiovascular Benefits: Some studies suggest a potential reduction in cardiovascular risks.

Wegovy (Semaglutide)

Much like Saxenda, Wegovy is a GLP-1 agonist but with a weekly dosing schedule. It's also been a herald of hope for individuals with a BMI of 30 or above.

Features and Benefits

• Long-term Weight Loss: Clinical trials have exhibited its prowess in sustaining weight loss over a longer period.
• Improved Glycemic Control: Like Saxenda, it also plays a vital role in managing blood sugar levels.

Comparison of Saxenda and Wegovy  for Weight Loss

Liraglutide and semaglutide are both glucagon-like peptide-1 (GLP-1) receptor agonists approved for weight management in adults who are obese or overweight. They promote weight loss by increasing feelings of fullness, delaying gastric emptying, and reducing appetite.

Efficacy

Several randomized controlled trials directly comparing liraglutide and semaglutide found that semaglutide led to significantly greater weight loss:

• In a 52-week trial of 957 adults, semaglutide doses of 0.2 mg or higher led to 11.2-13.8% weight loss, compared to 7.8% with liraglutide 3 mg (source).
• A meta-analysis of 23 trials with 11,545 participants found semaglutide 2.4 mg led to the greatest weight loss of 12.47 kg, followed by liraglutide 3 mg at 5.24 kg.
• On average, semaglutide 2.4 mg leads to 11-14% weight loss, compared to 5-9% with liraglutide 1.8 or 3 mg after 1 year of treatment.

Several factors contribute to semaglutide's greater efficacy:

• Higher dosing - Approved semaglutide doses are 0.5, 1, and 2.4 mg weekly, while liraglutide is 1.2 or 1.8 mg daily.
• Longer half-life - Semaglutide stays in the body longer with a half-life of 1 week vs 13 hours for liraglutide.
• Stronger GLP-1 receptor affinity.

Safety Profile

The most common side effects for both medications are mild-to-moderate gastrointestinal issues like nausea, vomiting, and diarrhea. These side effects are dose-dependent and often improve over time.

A few differences in safety:

• Semaglutide has a slightly higher incidence of gastrointestinal side effects than liraglutide.
• Liraglutide is associated with a small increased risk of gallbladder issues.
• The risk of hypoglycemia is very low for both in nondiabetic patients.
• No increased risk of cardiovascular issues or pancreatic inflammation were seen in clinical trials.

Overall, both liraglutide and semaglutide have good safety profiles, with semaglutide having slightly more gastrointestinal side effects. No new safety signals have been identified for either medication.
