– HOW DO THEY WORK? –
The most well-known of this new wave of medicine are Danish pharma agency Novo Nordisk’s Ozempic and Wegovy, in addition to US firm Eli Lilly’s Mounjaro.
These medicine improve the motion of a hormone within the pancreas referred to as “glucagon-like peptide 1”, or GLP-1, the title given to this household of medicines.

During scientific trials, the medicine have been discovered to scale back individuals’s weight by a median of 15 to twenty %.

A big research utilizing well being knowledge from a whole lot of 1000’s of US veterans printed in January discovered that GLP-1s will not be linked to the next danger of coronary heart issues or suicidal ideas, as had beforehand been instructed.
However there are uncommon instances of great unwanted side effects, resembling harm to the pancreas, it stated.

With billions of {dollars} at stake, pharma companies are racing to be the primary to market with a brand new therapy.
Novo Nordisk’s experimental drug amycretin may very well be much more efficient than present GLP-1s, based on early trial outcomes printed in The Lancet on Saturday.
There has additionally been a rising subject of analysis revealing the potential advantages of GLP-1 medicine past weight problems.
