Biological treatment for psoriasis recommended dosage

[Fred]

Isn't that what the trials for the drugs do. Determine what is the doses that are required to control the disease
And of course before it ever gets to the trials there are lab tests to see what cells they are blocking and no doubt how much is needed to successfully be a barrier and the length of time when it starts to fail, and when more is required . Is my best guess

Sounds like a good guess to me.

I found Stelara went up and down during the three month period. It would take a couple of weeks to get going, the middle was great but then towards the end of term it would start tailing off again.

So I wonder if Cosentyx have deliberately aimed for 1 month intervals. It would make sense to me to get a regular shot once per month. It's easier to remember, you could always stop if you picked up an infection and you don't have to inject too often.

But hang on Whisky, Gin, Vodka, Etc come in the same size and same strength, so why are bio's all different.
