Alprazolam
For high-incidence psychiatric disorders such as anxiety disorder and panic attacks, benzodiazepines are commonly used clinical treatment options. As an intermediate-acting preparation among them, alprazolam acts on the γ-aminobutyric acid receptors of the central nervous system to enhance the conduction effect of inhibitory neurotransmitters, which can rapidly relieve anxiety symptoms. It is also used to adjuvantly improve depressive symptoms accompanied by anxiety, exert sedative and hypnotic effects, and alleviate acute alcohol withdrawal reactions. Its applicable population covers adult patients with anxiety disorder and groups requiring short-term control of panic attacks. It has been clinically applied for more than 40 years and is one of the basic medications in the diagnosis and treatment pathway of psychiatric disorders.
The global market size of alprazolam preparations is stable at around 2.2 billion US dollars, and the annual sales in the domestic market exceed 1.5 billion yuan, with a compound annual growth rate of 3.8% in the past 3 years. Due to the early marketing time of this variety, generic drugs currently account for more than 95% of the domestic market. It has been included in the national centralized volume-based procurement, and the price of winning preparations has dropped by more than 80%. With the increase in the consultation rate of psychiatric disorders, the demand for upstream APIs continues to grow. Domestic API manufacturers are mainly pharmaceutical enterprises in East China and North China, and the overall supply pattern is relatively stable.
