Introduction
The innovative new injectable treatments for significant weight loss have revolutionized what people can expect as treatment in UK private clinics. GLP-1 receptor agonists and dual agonists Anti‐obesity and anti‐metabolic weight loss drugs that are used for alcohol use disorder Anti‐obesity and anti‐metabolic compounds have been revolutionized with the introduction of GLP‐1 receptor agonists and their dual agonists. With obesity on the rise and a growing market of patients wanting non-surgical weight loss procedures, patients are seeking intervention-based options for long term results.
Mounjaro and ozempic are new medications that are offering new hope to those who are struggling to lose weight using traditional methods. Clinics throughout the UK have said that they have seen a huge increase in queries about these drugs, spurred on by both clinical recommendations and success stories from patients. This resource contrasts the two to inform patients and clinicians about which drug might be right for them.
What is Ozempic?
Ozempic is a GLP-1 analogue that first received approval as a type 2 diabetes drug. It is designed to duplicate the actions of the body weight’s natural GLP-1 hormone, which helps control insulin production, particularly in patients with type 2 diabetes. slow the rate at which food leaves the stomach and reduce appetite. Its most common indication is glycaemic control, though it has been used off-label for weight reduction in people with obesity or metabolic syndrome.
The mechanism of Ozempic promotes a sense of fullness after eating which can reduce calorie consumption. Interest among clinicians in semaglutide surged after a higher-dose version was successful in a branded form named Wegovy, which was specifically designed for weight loss, resulting in patients achieving significantly more weight .
What is Mounjaro?
Mounjaro is made up of a new drug called tirzepatide, which is a dual GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptor agonist. This twofold action works on various routes related to glucose and appetite control, and it promotes weight loss effectively. and thus acts as a powerful compound in management of Diabetes as well as to lose weight.
The two-pathway activity of tirzepatide provides additional metabolic benefits through improved insulin sensitivity and lipid metabolism. Thanks to its wider mechanism of action, Mounjaro has yielded better results in early studies than single-pathway GLP-1 agonists including semaglutide.
Ozempic vs Mounjaro: How Do They Work?
Semaglutide and tirzepatide work by changing hormones related to satiety and glucose metabolism. Semaglutide stimulates the GLP-1 receptor and therefore enhances the insulin response to meals – by increasing the amount of insulin released in response to the increase in blood glucose – and also by reducing the amount of glucagon released by the alpha cells of the pancreas. It slows and reduces the hunger signals to the brain.
Tirzepatide takes it a step further by also turning on GIP receptors. This combined receptor activation results in enhanced energy balance, enhanced insulin sensitivity, and possibly enhanced inhibition of food intake. This divergence in action possibly underlies the discrepancy between patient reaction and the net total amount of weight loss between the 2 medications.
Clinical Trial Results
Semaglutide has been studied extensively in the STEP program,7–10 including in STEP 1 and STEP 4, and average weight losses of approximately 14–15% were achieved in participants not having diabetes using weekly injections. The trials also reported signs of major improvements in cardiovascular risk profiles and quality of life indices.
The SURMOUNT-1 trial was conducted for the evaluation of tirzepatide and involved non-diabetic adults with obesity. The most effective dosaged- group had average % weight losses of over 20%, and up to 22.5%. These findings indicate Mounjaro as an agent with a potential higher efficiency for absolute weight loss.
It’s hard to say for sure in head-to-head comparisons, but early data suggests that users tend to see more and faster results with tirzepatide. Additional trials are underway to evaluate long-term sustainability and safety in wider populations.
Real-World Results (UK clinics and anecdotal)
Clinical reports are supported by those from the clinic in the UK and on-line groups. Patients on Mounjaro typically say they lose weight faster the first few months. Circumference reduction is often observed to be significantly larger with decreased amounts of food and snacking.
Those on Ozempic also experience steady, and consistent weight loss with less side effects, once the adjustment period settles out. A few people did have weight plateaus after a few months on the medication that can be dealt with by increasing the dose or lifestyle changes.
Pricing in the UK
Ozempic costs between £150 and £250 a month, depending on the dose and brand. It is also more readily available and has had a longer presence in the UK market. Introduced more recently, Mounjaro costs between £200 and £350 a month.
Typical packages sold by UK online pharmacies & clinics
The most common services offered by private clinics are treatment packages that include a virtual consultation, prescription issuance, follow-up care and the medication. Ozempic is frequently found in packages and Mounjaro may be hard to come by on account of its supply being less than the demand.
Value for Money
Cost-effectiveness-wise, Mounjaro could be a better value option for patients who want faster and more overt weight loss. But Ozempic is a less expensive option with established long-term results, especially for those who are okay with slow-but-steady.
Neither drug is funded by the NHS for weight loss but those patients with comorbid Type 2 Diabetes may have access to these drugs through diabetic care plans.
Ozempic Dosage
Ozempic is given as a weekly subcutaneous injection. The treatment commences at 0.25 mg four weeks and then is augmented to 0.5 mg. If necessary the dose may be raised to 1 mg, and in some instances to 2 mg.
The slowly escalating dose has been designed to reduce GI side effects. The prefilled pen is simple to use and can be taken in the convenience of the home.
Mounjaro Dosage
Mounjaro is given by weekly injection. The recommended starting dose is 2.5 mg, which is titrated in 2.5 mg weekly increments to a maximum dose of 15 mg. The titration regimen is critical to negotiate efficacy and tolerability.
A great patient feedback is the simplicity of the pen mechanism and the easy dosage labelling on the pen.
User Convenience & Experience
Pre-filled, easy-to-use injection pens are available for both medications. Mounjaro’s pen is a dose-setting-free pen, minimizing the number of handling steps. Ozempic has convenience features too and it should have a lower learning curve for patients to adjust their dosing.
Tolerability is subjective. Some people find there is a stronger hit in the first phase with Mounjaro because it’s got 2 hits, some people have no cravings and more satisfaction. People going on Ozempic often experience a smoother transition, but may not see similar-looking changes as you will.
Common Side Effects
Gastrointestinal complaints such as nausea, vomiting, diarrhoea, and constipation have been reported in association with both drugs. They are worst when the dose is being increased, but also often improve with time.
Suppression of appetite is a desired effect, but may cause tiredness or lack of interest in eating. Proper hydration and good nutrition are also essential to manage these side effects.
Serious Risks & Monitoring
There is a low, but existing, risk of acute pancreatitis and cholecystitis. Liver and gall bladder function tests should be monitored at regular intervals during treatment, particularly in patients with a prior history of these hepatic disorders.
Some patients may feel a faster heart rate, or changes in mood. Cardiac evaluations may be considered, especially in those with underlying heart diseases.
