brand vs. generic- when would you give out brand drugs only?

[bongoo]

When would it be clinically necessary to keep to a specific brand instead of generics?
To this question, I was thinking NTI drugs such as theophylline, biological products and modified release preparations.
But the categories that I have mentioned may be too broad. For example, digoxin, one of NTI-drugs, does not need to be
given in a specific brand.

Could you help me out?
And where would find information regarding this? SPCs?

Seemples.....Dr prescribes brand, give brand. Dr prescribes generic, give generic. PPA will only pay for what is prescribed.
However, some companies have equalisation arrangement with a manufacturer and give the brand. Eg ventolin.

Which medicines should be considered for brand-name prescribing in primary care? - NeLM

[Asterix]

The reasoning for keeping it clinically necessary for brand prescribing is due to the difference in the bioavailability which is the amount of drug that ends up in system circulation. This will obviously differ between different brands and hence patients will have different clinical output if their brand was changed.

Here's a list (not exhaustive)
* Lithium
* Theophylline
* Diltiazem
* Insulin

P.s. I have just help another person Nik and John, you two must be proud

Not so fast John - his response looks suspiciously similar to one of mine to a recent thread. Perhaps when different and more tricky questions arise we'll see the true depth of his knowledge...
