What are the different types of barbiturates?
In the year 1903, barbiturates were initially used for its therapeutic benefit. Since then more than 2,000 derivatives of barbituric acid have been synthesized, out of which, many are still available in the market. The main difference amongst barbiturates is the duration of action. The effect of long-acting barbiturates may last up to two days; however, the effect of short acting and ultra-short acting barbiturates last only for a few minutes or few hours. Barbiturates may be injected into veins or muscles, but usually taken as oral pills.
