Key Differences

Sedatives are used to promote calmness and reduce excitement in patients, making them more manageable or preparing them for procedures. Whereas tranquilizers are more specifically aimed at reducing anxiety and tension, often having a broader scope of use including treating mental health conditions.
Sedatives, by their nature, may not always induce sleep but can lead to drowsiness as a side effect. On the other hand, tranquilizers, especially the minor tranquilizers like benzodiazepines, are known for their anxiolytic (anxiety-reducing) properties and can also induce drowsiness or sleep as a side effect.
Sedatives are often categorized based on their potency and the duration of their effects, ranging from mild sedatives like antihistamines to more potent ones such as barbiturates. Whereas tranquilizers are divided into two main categories: major tranquilizers, which are antipsychotics used to treat psychiatric conditions, and minor tranquilizers, used for anxiety and stress-related conditions.
In medical practice, sedatives are frequently utilized to facilitate procedures by calming the patient or inducing sleep, for instance, before surgery. Tranquilizers, however, are more commonly prescribed for ongoing management of conditions like anxiety disorders, playing a crucial role in psychiatric treatments.
Sedatives' effects are primarily on the central nervous system to reduce activity and induce calmness, whereas tranquilizers may have a wider range of effects, including altering neurotransmitter levels to reduce anxiety and tension.
