What is the half-life of extended-release morphine?

What is the half-life of extended-release morphine?

The terminal half-life of morphine is 2 to 4 hours, however, a longer term half-life of about 15 hours has been reported in studies where blood has been sampled up to 48 hours.

What is the equation for half lives?

Mathematically, the half life can be written in terms of the decay rate: Half-life = – ln(2) / k. The natural logarithm (ln) is a mathematical function that is the inverse to the exponential (e) function. You can find the natural logarithm on a scientific calculator where it will be labelled “ln.”.

What is the half life story?
