A drastic surge in demand has put medicine like Wegovy, Victoza and Ozempic in brief provide

The blockbuster weight-loss drug semaglutide and its rivals promise to assist reverse the worldwide weight problems epidemic – if solely extra of the individuals who would profit from these therapies might afford them. However this yr might see welcome steps in that route.
For years, weight-loss medicine had been in brief provide, however by the tip of 2024, producers had caught up with the massive demand. However medicines corresponding to semaglutide (offered as Wegovy or Ozempic) stay very costly, usually costing a number of thousand {dollars} for a yr’s provide.
That price ticket places them past the attain of many of the greater than 1 billion individuals all over the world who’ve weight problems; solely 3 per cent of eligible individuals within the US are on weight-loss medicine, and fewer than 1 per cent elsewhere, based on the monetary firm Morgan Stanley.
However two key developments are anticipated in 2026. One is the approval of a drug referred to as orforglipron in varied nations. This works in the identical manner as semaglutide, by mimicking the motion of a hormone referred to as GLP-1, which reduces urge for food. However it’s a small molecule, which means that not like semaglutide, it may be absorbed by means of the intestine and thus may be taken in tablet kind.
“Tablets are cheaper to supply, simpler to retailer and less complicated to distribute,” says Lora Heisler on the College of Aberdeen within the UK. “In brief, drugs can present remedy to extra individuals who want it.”
Semaglutide, against this, is a big molecule, a form of protein. Massive-molecule medicine are typically far more troublesome and costly to fabricate. Additionally they normally must be injected, and supplying them in injector pens provides to the prices and problems. These are the explanation why producers lengthy struggled to fulfill the demand for GLP-1 medicine after they grew to become standard for weight reduction.
Confusingly, there’s a tablet type of semaglutide referred to as Rybelsus, which is authorized for kind 2 diabetes, and the maker of semaglutide – Novo Nordisk – has utilized for approval for a tablet kind for weight reduction.
Nevertheless, Rybelsus shouldn’t be an bizarre tablet. It accommodates semaglutide together with a substance referred to as salcaprozate sodium, which neutralises abdomen acid and “fluidises” cell membranes, permitting semaglutide to move by means of the cells lining the intestine and enter the bloodstream. You don’t need this occurring with partially digested meals, so Rybelsus needs to be taken a minimum of 8 hours after consuming, and other people can not eat or drink for half an hour after taking it.
All for this reason orforglipron ought to be cheaper to supply than semaglutide, and why it may be taken with out the particular necessities for Rybelsus.
The approval of one other GLP-1 drug will even enhance competitors between pharmaceutical firms. The maker of orforglipron, Lilly, has but to announce pricing however has indicated it will likely be cheaper than different GLP-1 medicine.
The one draw back is that it appears to be much less efficient, with individuals on the best dose shedding round 10 per cent of their weight after 72 weeks, in contrast with round 14 per cent for semaglutide, although a head-to-head trial might be wanted to substantiate this.
The second massive growth is the expiry of semaglutide patents in nations together with China, India, Brazil, Canada and Turkey – that’s, for a giant chunk of the worldwide inhabitants. This implies drug producers can begin promoting generic variations.
Generics must be authorized and meet the identical requirements as patented variations, however may be less expensive. “When a drugs loses patent safety, usually generic competitors reduces costs by as a lot as 90 per cent,” says Jeremy Durrant at Medicines UK, an affiliation of generic medication producers.
So quickly much more individuals might have entry to those medicine. However in tips launched in December, the World Well being Group (WHO) really helpful that individuals ought to get counselling on behavioural and way of life adjustments along with the medicine, to maximise the advantages and guarantee they persist. “Medicine alone can not resolve the worldwide weight problems burden,” wrote Francesca Celletti on the WHO.
