Abstract
GG is a useful sedative and anaesthetic agent in horses. Used alone, or in conjunction with barbiturates, it produces a uniformly smooth recovery from anaesthesia. The need to infuse large volumes to obtain the desired effect is a disadvantage of this agent. Few critical studies have been made on the short and long term effects of administration of GG to horses. Its pharmacology and clinical use are described and indicate that it is a safe and useful drug.
