There are 24 #sp^2# hybridized carbon atoms in Lipitor®.

Every double bonded carbon in a molecule is #sp^2# hybridized.

The structure of Lipitor® is

In the three benzene rings, there are 18 #"C=C"# bonds, for 18 #sp^2# hybridized carbon atoms.

In the pyrrole ring, there are 4 #"C=C"# bonds, for 4 #sp^2# hybridized carbon atoms.

The amide group has a #"C=O"# bond, for another #sp^2# hybridized carbon atom.

The carboxyl group has a #"C=O"# bond, for another #sp^2# hybridized carbon atom.

That makes 24 #sp^2# hybridized carbon atoms.
