Which drug class is the most widely prescribed according to combined sales?

Benzodiazepines are known to be the most widely prescribed drug class according to combined sales due to their effectiveness in treating anxiety disorders, insomnia, muscle spasms, and seizure disorders. These medications work by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA), which produces a calming effect on the brain. The widespread prevalence of anxiety and stress-related disorders in the population contributes to the high demand for benzodiazepines, leading to substantial sales figures.

Additionally, the prescribing patterns are influenced by the quick onset of action, the broad range of conditions they can address, and their established history of use.
