An oral pharmaceutical composition is provided that can comprise a
rho kinase inhibitor, for example,
fasudil, a pharmaceutically acceptable salt thereof, a
hydrate thereof, a
prodrug thereof, a substituted derivative thereof, or a
metabolite thereof, or any combination thereof, the
rho kinase inhibitor having a
bitter taste; and an
ion exchange resin. The
ion exchange resin can partially or fully
mask the
bitter taste of the
rho kinase inhibitor, making the composition more palatable. The composition can comprise a
solid dosage form, and / or a
liquid dosage form. The
solid dosage form can comprise a
powder, granules, a tablet, or a
capsule, or any combination thereof. The composition can be present, for example, in a unit
dose, in an amount sufficient to treat a neurodegenerative
disease. A method of treating the neurodegenerative
disease with the oral pharmaceutical composition is provided. The method can ameliorate a symptom of a neurodegenerative
disease.
