A new oral weight-loss drug is showing promising results for people living with obesity or who are overweight. In a phase II clinical trial published in Nature Medicine, participants taking the experimental medication aleniglipron lost up to 12% of their body weight over 36 weeks.The study included contributions from Robert Kushner, MD, professor emeritus of medicine at Northwestern University and a longtime expert in obesity treatment.Aleniglipron belongs to the GLP-1 family of drugs, the same class as popular medications such as Ozempic and Wegovy. These treatments help people lose weight by mimicking a natural hormone that reduces appetite, increases feelings of fullness, and helps regulate blood sugar levels.What makes aleniglipron different is that it comes in pill form. Most currently available GLP-1 medications require injections and often need special storage, which can make them less convenient and more difficult for some patients to access.Researchers believe an oral option could make treatment easier for many people. Because aleniglipron is a small-molecule drug—meaning it is chemically manufactured rather than peptide-based—it can be produced more efficiently and potentially at a lower cost.“Aleniglipron is different because it’s a small molecule that can be taken with or without food,” Kushner said. “Most medicines people take every day, from aspirin to blood pressure drugs, are small molecules. That also creates opportunities to combine it with other treatments in the future.”If further studies confirm its safety and effectiveness, aleniglipron could offer a more convenient alternative to injectable GLP-1 medications and help expand access to obesity treatment.Why Is GLP-1 Drug A Medical Breakthrough?Dr Shubham Vatsya explains that it took 20 years of research for scientists to come up with these medicines. This drug underwent proper lengthy trials, and have been approved by the US Food and Drug Administration (FDA), "which is not obtained by giving any bribe".He also noted that when a person is not able to lose weight, Ozempic and drugs alike give a "head start" to them, along with a hope.Talking about side effects, he says that every drug has its side effects, this is where a doctor's role comes in."Now, the person who is not able to lose weight, if you tell him 'you hit 100 kg bench press', he will break his shoulder. He needs a kickstart somewhere. This is what weight loss drugs allow," he says.He also points out that the scientists who made GLP-1 agonists got a Nobel Prize, which "cannot be a scam". This is what makes weight loss drugs truly different.Also Read: Raising Sons Linked to Faster Cognitive Decline in Later Life, Study FindWhat Are GLP-1 Drugs?GLP-1 Drugs stand for Glucagon-like peptide 1, a naturally occurring hormones that helps regulate blood sugar and appetite after eating. It was first identified almost 50 years ago and scientists have since uncovered its role in type 2 diabetes.
