The present invention relates to a serotonin 5-HT
2C
receptor activator containing a compound represented by the formula
wherein ring A is a 5- or 6-membered aromatic heterocycle optionally having substituent(s), and ring B is a 7- to 9-membered ring optionally having substituent(s) other than an oxo group wherein the combination of m and n (m,n) is (1,2), (2,1), (2,2), (3,1), (3,2) or (4,1), or a salt thereof or a prodrug thereof, and a fused heterocyclic compound having a serotonin 5-HT
2C
receptor activating action and the like.

2C
receptor, and a method of screening for a therapeutic drug for cystoceles or enteroceles, including increasing an intravesical pressure after bilateral transection of the hypogastric nerve and pudendal nerve of an animal, and measuring a closure response in the urethra, the rectum or the vagina observed at that time. A serotonin 5-HT
2c
receptor activator containing a compound represented by the formula:
wherein each symbol is as defined in the specification, or a salt thereof.
This invention relates to compounds which modulate receptors of the 5-HT2 family of receptors, and particularly to compounds which modulate 5-HT2C receptors. Compounds of the invention include agonists and selective agonists for the 5-HT2C receptor Compounds of the invention include selective agonists for the 5-HT2C receptor which exhibit significantly less or no agonist activity on the 5-HT2A receptor and/or the 5-HT2B receptor. Compounds of this invention are those of Formula I and pharmaceutically acceptable salts, esters and solvates (including hydrates) wherein variables are defined in the specification hereof.
