Abstract: The invention provides a vehicle that can deliver drugs specifically to the body and a pharmaceutical preparation using the same. Disclosed is a drug delivery vehicle for cancer therapy, comprising a cationized viral envelope vector, as well as a pharmaceutical preparation comprising a drug enclosed in the vehicle. The viral envelope vector is for example HVJ-E derived from a Sendai virus, and cationization can be conducted by binding hyaluronic acid-introduced cationized gelatin or ethylene glycol-introduced cationized gelatin with the viral envelope vector. The drug to be enclosed is a nucleic acid, a vector containing a nucleic acid sequence, a protein based drug or pharmaceutical with a low-molecular compound.
