Q

What is ‘steady state’ of a drug?

A

When you give several doses, the plasma conc rises and falls but doesn’t fall back to 0 so a small increase with every dose. Steady state is when it is in equilibrium with its elimination. Normally 4 to 5 times the drug’s half-life. So may need a loading dose.
