1. An ophthalmic pharmaceutical composition consisting essentially of:
- at least one pharmaceutical component;
at least one water-immiscible material; and
optionally a viscosity-modifying compound;
wherein the pharmaceutical component has a Formula I, II, II, IV, V, or VI, and the pharmaceutical component has a solubility in water of less than about 0.1 mg/g measured at a pH of about 7.4 and at 25°
C., and the pharmaceutical component and the water-immiscible material are combined to form at least one mixture suitable for formulation for ocular administration.
