There are 24 $s p^{2}$ $sp^2$ hybridized carbon atoms in Lipitor®.

Every double bonded carbon in a molecule is $s p^{2}$ $sp^2$ hybridized.

The structure of Lipitor® is

In the three benzene rings, there are 18 $C=C$ $"C=C"$ bonds, for 18 $s p^{2}$ $sp^2$ hybridized carbon atoms.

In the pyrrole ring, there are 4 $C=C$ $"C=C"$ bonds, for 4 $s p^{2}$ $sp^2$ hybridized carbon atoms.

The amide group has a $C=O$ $"C=O"$ bond, for another $s p^{2}$ $sp^2$ hybridized carbon atom.

The carboxyl group has a $C=O$ $"C=O"$ bond, for another $s p^{2}$ $sp^2$ hybridized carbon atom.

That makes 24 $s p^{2}$ $sp^2$ hybridized carbon atoms.
