Which of the following tranquilizers is considered relatively mild and suitable for relieving tension?

Chlordiazepoxide is indeed recognized as a relatively mild tranquilizer that is effective for alleviating tension. It belongs to the benzodiazepine class of medications, which work by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA) in the brain, resulting in a calming effect. This makes it suitable for treating anxiety and tension in a controlled manner without severely sedating the patient.

Valium, also known as diazepam, is a stronger benzodiazepine that can be used for anxiety relief but is more potent and may have stronger sedative effects than Chlordiazepoxide. Equanil, or meprobamate, is an anxiolytic that can produce significant sedation, and while it is used for anxiety, it may carry a higher risk of side effects and dependency. Meprobamate is often considered to be more sedating than Chlordiazepoxide and is associated with a higher potential for abuse.

Therefore, while all these medications can serve to relieve tension, Chlordiazepoxide stands out as a milder option, making it more suitable for individuals who need to manage their anxiety without experiencing heavy sedation or significant side effects.
