The alpha-decay half-lives of nuclei in the ground states and isomeric states have been calculated within the WKB approximation and Royer's formulas. The barrier in the quasimolecular shape path is determined within a generalized liquid drop model (GLDM), in which the centrifugal potential energy has been introduced to study the unfavored alpha-decay. The agreement between the calculated results and experimental data indicates the reliability of studying alpha-decay of isomeric states with the generalized liquid drop model. We find that their is no significant difference of preformation probability between isomeric states and the corresponding ground states generally in favored alpha-decay. Additionally, we extended Royer's formulas by taking account of the role of centrifugal barrier to study the unfavored alpha-decay, and some predicts on the alpha-decay half-lives of isomers are made. Finally, the effects of angular momentum transfer and Q{sub a}lpha on alpha-decay half-life have been discussed.
