Hello, I'm a specialist in the field of pharmacology with a focus on benzodiazepines, a class of psychoactive drugs that are commonly used for their anxiolytic, sedative, and hypnotic effects. I'm here to provide you with a comprehensive understanding of the longest-acting benzodiazepines.
Benzodiazepines work by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA) in the brain, which produces a calming effect. They are used to treat a variety of conditions, including anxiety, insomnia, and seizures. However, they also have the potential for dependency and withdrawal issues, which is why it's important to understand their durations of action.
When considering the "longest-acting" benzodiazepines, we're looking at the duration of their effects rather than the time it takes for them to start working, which is referred to as the onset of action. The onset can vary from fast-acting (like alprazolam) to slow-acting (like oxazepam). But the question at hand is about the duration of action, which is how long the drug continues to have an effect on the body.
Based on the information provided, Chlordiazepoxide (Librium), clonazepam (Klonopin), diazepam (Valium), flurazepam (Dalmane), and quazepam are all mentioned as long-acting agents with a duration of action ranging from 1 to 3 days. Among these, diazepam (Valium) is particularly notable because it not only has a long duration of action but is also metabolized into several active metabolites, some of which have even longer half-lives than the parent drug. This can result in effects that are felt for an extended period, especially in individuals who are slow metabolizers.
It's important to note that the classification of a benzodiazepine as "long-acting" can be somewhat relative and depends on the context in which it's being used. For instance, while diazepam has a longer duration of action compared to other benzodiazepines like alprazolam, it may still be considered short-acting when compared to non-benzodiazepine hypnotics with durations of action that can last several times longer.
Additionally, the long duration of action of these drugs can lead to a higher risk of dependence and other adverse effects, including cognitive impairment, especially in the elderly. Therefore, they are typically prescribed with caution and for short-term use only.
In summary, while there are several benzodiazepines with long durations of action, diazepam (Valium) stands out due to its active metabolites and extended effects. However, it's crucial to use these medications under the guidance of a healthcare professional to minimize the risks associated with long-term use.

Oxazepam (Serax) has a slow onset, and lorazepam (Ativan), alprazolam (Xanax), and clonazepam (Klonopin) have intermediate onsets of action. ... Chlordiazepoxide (Librium), clonazepam (Klonopin), diazepam (Valium), flurazepam (Dalmane), and quazepam are long-acting agents with duration of action of 1 to 3 days.
