a sedative is possible, but its more likely that he is in a new environment, with new people, horses, food and surroundings, and had a bad day. When he jumped(could you have accidently kicked him when you got on? Does your saddle fit?) for the first time he may have learned that jumping around will get his rider off, so he tried it again and succeded. if you have his head pulled around when you get on he cant run off. also be very careful your saddle isnt pinching and you are not accidentally kicking him.
