Over the vacation break Exponential View republished a chunk by Azeen Azhar it had run earlier within the 12 months on GLP-1 medicine. (In different phrases, medicine like Ozempic.) First time round, I’d observed the headline, however not had time to get into the element. However seeing it through the vacation meant I used to be capable of give it extra consideration.
The Exponential View headline story is that this:
I reckon that they would be the most impactful know-how within the US over the subsequent two years, with extra significant and measurable impacts than both synthetic intelligence or renewable applied sciences.
So if that’s proper, they’re fairly a giant deal. The Exponential View piece is behind a paywall (I’ve a subscription) however Azeem Azhar hyperlinks to substantive content material that’s free-to-air that goes into extra element on the mechanics of the medicine.
Diabetes sufferers
Backing up a bit: GLP-1s (extra formally, ‘GLP-1 receptor agonists’) have been launched into the market by the big pharma corporations initially as a means to assist sufferers with Sort 2 Diabetes, however have since turn into a means to assist sufferers who’re obese to handle their weight down.
As soon as of the implications of this, apparently, is that diabetes sufferers, who actually want the medicine, have problem guaranteeing their provide.
All the identical, sufferers can’t get sufficient of them, wanting on the US information:
GLP-1 prescriptions have quadrupled within the US during the last three years. Latest information reveals that almost 5% of sufferers receiving any prescription at the moment are prescribed a GLP-1 RA. By some estimates, there have been 9 million prescriptions for GLP-1s on the finish of 2023, which implies that 3% of Individuals are already on these medicine.
Market cap
The potential market in American alone is way bigger, provided that 100 million Individuals undergo from weight problems.
The influence on the pharma corporations who make these medicine has been dramatic. Exponential View shared a chart from the Economist that confirmed the expansion within the share value of Eli Lilly, which makes Mounjaro, and Nono Nordisk, which makes Ozempic. Eli Lilly turned essentially the most worthwhile pharmaceutical firm on this planet in 2023 off the again of its GLP-1 orders, and Novo Nordisk essentially the most worthwhile firm in Europe.

Extending length
GLP-1s are discovered naturally within the human physique, however are ingested in a short time. What the pharma corporations have carried out is mix it with different chemical substances to increase the length of their results, because the psychiatrist Scott Alexander notes:
By enjoying round with its construction, Massive Pharma was finally capable of create liraglutide (twelve hours), semaglutide (one week), and cafraglutide (one month).
So we should always step again and ask what’s going on right here. Are GLP-1s a ‘marvel drug’ or a fad? Scott Alexander has seemed into this in some element, and I’ll attempt to summarise his argument.
He begins by noting the widespread vary of issues that they appear to have the ability to deal with:
GLP-1 receptor agonist medicines like Ozempic are already FDA-approved to deal with diabetes and weight problems. However an growing physique of analysis finds they’re additionally efficient in opposition to stroke, coronary heart illness, kidney illness, Parkinson’s, Alzheimer’s, alcoholism, and drug habit.
Addictive behaviours
In fact, that makes them sound like a marvel drug, moderately than a fad. Scott Alexander runs by way of the fairly well-known explanations of why they work for diabetes, after which factors out that the burden loss results have been sudden. We observed that they have been having that impact earlier than we understood why.
What’s extra fascinating is that GLP-1s are additionally related to reductions in addictive behaviours. Though that is often reported anecdotally, a extra sturdy meta-study in Mind Science which used a ‘combined strategies’ strategy to analyse social media experiences about ‘Substance use, compulsive habits, and libido’ additionally discovered this to be the case. From the summary:
In whole, 29.75% of alcohol-related; 22.22% of caffeine-related; and 23.08% of nicotine-related feedback clearly said a cessation of the consumption of those substances following the beginning of GLP-1 RAs prescription… Relating to behavioral addictions, 21.35% of feedback reported a compulsive purchasing interruption, while the sexual drive/libido parts reportedly elevated in a number of customers.
Receptors
As Scott Alexander notes, there is no such thing as a such a factor as a “miracle drug”. Medication work by performing on receptors within the physique or the mind:
There are two believable locations GLP-1 medicine might decrease weight: the physique or the mind. Within the physique, they may change abdomen contraction price, hormone manufacturing, and so forth. Within the mind, they may management the psychological sensation of starvation. To separate these two results, scientists bred rats that solely had GLP-1 receptors in a single place or the opposite. The outcomes have been unequivocal: Ozempic and its family work within the mind.

There are the explanation why that is shocking, and the mechanisms are positively complicated (learn Scott Alexander for all of this), however at a headline degree GLP-1s appear to—by way of totally different mechanisms—suppress starvation and in addition influences the (dopamine-based) rewards system in such a means that it suppresses habit:
Broad-spectrum dampening of the reward system is a horrible destiny… However the existence of silver bullet anti-addiction medicines—Ozempic isn’t the one one, naltrexone appears to deal with a complete host of various drug and behavioral addictions—suggests there’s additionally a type of narrow-spectrum dampening, one which impacts addictions and nothing else.
Financial drag
Let’s assume, subsequently, that these results are actual and that they maintain, and take a look at the broader implications of this. Exponential View quotes Goldman Sachs and Morgan Stanley on GDP and labour market participation, which tells you extra in regards to the thinness of public coverage dialogue than anything.
However they each level to the dimensions of the financial drag of America’s weight problems epidemic:
Morgan Stanley reckons the damaging macroeconomic influence of weight problems is “3.6% of U.S. gross home product with a possible $1.24 trillion in oblique prices from misplaced productiveness”…. Goldman Sachs individually reckons the impact of tackling the weight problems epidemic by way of GLP-1 agonists might fluctuate between including 0.1 to 1.1% to GDP.
In fact, if the consequences in lowering habit are actual, you then may see this offset by decrease consumption. Walmart say that these utilizing GLP-1 medicine purchase much less meals, and are much less more likely to eat out or order meals for dwelling supply.
In fact, this isn’t the actual impact. The true impact, in the event that they maintain, is about wellbeing: first to enhance the bodily high quality of lifetime of customers, so they can take part extra absolutely in social and cultural life in addition to financial life. And second, in lowering addictive behaviour, it improves the psychological high quality of life as effectively.
Bailing out Massive Meals
In fact, this additionally comes right down to price. A 30-day provide of Ozempic prices $900 within the US, which is 5 instances as a lot as in Japan and 10 instances as a lot as in Britain or Australia.
However it’s additionally value stepping again and looking out on the greater image. I’ve written right here lately about each the exterior prices of the meals market—$10 trillion a 12 months globally in keeping with the Meals and Agriculture Group—and the addictive nature of Extremely-Processed Meals.
So that is additionally a narrative about late capitalism. Slightly than coping with the causes of the weight problems epidemic within the Massive Meals system, private and non-private well being techniques find yourself paying billions, or extra, to Massive Pharma, to take care of the implications.
