The present invention relates to a pharmaceutical composition comprising nebivolol with an improved dissolution rate and a preparation method thereof. The pharmaceutical composition, containing nebivolol or a pharmaceutically acceptable salt thereof, an alkalizing agent, and a pharmaceutically acceptable additive, for prevention or treatment of cardiovascular diseases, does not cause a decrease inthe dissolution rate of nebivolol and can significantly improve the dissolution rate, not only at low pH, such as pH 1.2, but also at a relatively high pH of 5 to 7, so that an improved therapeutic effect can be expected. In addition, the pharmaceutical composition can reduce the preparation cost since the micronization of nebivolol or the addition of a wetting agent is not required, and can minimize the occurrence of a deviation of bioavailability due to pre- or post-meal intake since there is little deviation of the dissolution rate due to the pH change, thereby maintaining a constant pharmaceutical action, and thus, the pharmaceutical composition is very useful in the preparation of a composite preparation containing a nebivolol preparation, or another active ingredient, such as rosuvastatin calcium.
