Depression, the global prevalence rate has been as high as 3% to 5%, especially severe depression, after the full course of treatment of drugs, there are still 30% of the incurable depression, so the current clinical needs are still seriously needed! Antidepressants are also emerging as a result! Among the many drugs on the market, it is worth mentioning the variety, when (Ace) ketamine, after decades of clinical use, finally in 2019 through the improvement of dosage forms and officially turned to the field of antidepressants, and become the world's only fast-acting antidepressants, causing widespread concern in the industry! Ketamine hydrochloride has been on the market for 50 years In February 1970, ketamine hydrochloride (a cyclosterone derivative) developed by Par Sterile Products (a subsidiary of Endo) was approved by the FDA for clinical use in anesthesia under the name Ketalar®.
the species was originally synthesized by Stevens in 1962, first used in humans by Corssen and Domino in 1965, and clinical trials of pain, depression and schizophrenia have been conducted in addition to approved anaesthetic adaptations.
Figure 1.1 Emotional Disorders in which ketamine acted on the signaling path of NMDA Source: Astamine 2019 Challenge Depression August 1997, as a right-hand isomer of ketamine, Acetaminosterone hydrochloride was approved for sale in Germany under the trade name Keesttan®, an intravenous agent for anesthesia and analgesics.
PS: Intravenous ascetamine is highly addictive and difficult for doctors in clinical practice, so it is extremely important to choose a safe and effective method of use.

The approval was based on the results of a Phase III clinical trial involving more than 1,700 adult TRD patients, which showed that in short-term studies, patients in the Spravato treatment group had significantly improved depressive symptoms during the fourth week of treatment compared to the placebo-combined oral antidepressant group, and that in long-term studies, Spravato combined treatment reduced the risk of recurrence by 51 percent compared to patients who maintained a placebo and oral antidepressant program.
In addition to the above information, Acetamine hydrochloride has been recognized by the FDA for two breakthrough therapies, including the treatment of drug-resistant depression (November 2013) and severe depression at risk of suicide (August 2016).
addition, its drum chamber-injected gel preparation (for the treatment of tinnitus) is currently in Clinical Phase III and was awarded fast track by the FDA in July 2016. development of
ketamine compound varieties In addition to the above-mentioned ketamine/ ascettamine and its different dosage forms, for ketamine compound preparations, there are also varieties into development, and mainly concentrated in EpiCept developed amitin/ketamine, aminobenzene/ketamine.
➤ Amitin/ketamine This variety is a compound drug consisting of 5-serotonin reuptake/dethyroidine reuptake inhibitors (amitin) and ketamine, initially E PiCept (acquired by Immune in August 2013) was developed and a cooperation agreement was reached with National Cancer Institute, which is currently in the clinical Phase III trial phase for the treatment of epitheliopathy, pain, neurotoxicity and unspecified adult solid tumors.
PS: In 2010, amritillin/ketamine was recognized by the FDA as an orphan drug for treating nerve pain after shingles, and in 2012, the FDA granted amritillin/ketamine a fast-track approval channel for the treatment of peripheral nerve pain caused by chemotherapy.
➤ Aminobenzene/Ketamine This variety is a compound consisting of sodium ion channel antagonists (aminobenzene) and ketamine, also developed by EpiCept, for the treatment of adaptive neuropathic pain that was in clinical phase I/II.
Domestic ketamine-related clinical application statistics domestic, in recent years, more attention to nasal spray dosage form (whether S configuration or R configuration), are currently in the clinical stage, the number of trials is small, and no varieties have been approved for production;
Table 4.1 Domestic clinical trials related to ketamine in the last 5 years "in-process/completed" domestic ketamine-related registration declaration statistics Domestic, ketamine-related product registration declaration, mainly have the following varieties, namely, "ketamine hydrochloride injection", "ketamine testing kit", "? Morphine/methamphetamine/ketamine triad test kit, right ketamine hydrochloride injection, hydrochloric acid ascettamin nasal spray, hydrochloric acid ascetamine injection, hydrochloric acid (R)-ketamine nasal spray, etc.
From 2000 to the present, the relevant products have been approved for production of ketamine testing kit developed by Aikang Biotechnology Co., Ltd., morphine/methamphetamine/ketamine tri-in-one test kit developed by Shanghai Kaitron Biotechnology Co., Ltd., and ketamine ketamine hydrochloride injection developed by Jiangsu Hengrui Pharmaceutical Co., Ltd.
And further inquiries, for ketamine injections, the domestic market sales enterprises are mainly Fujian Gutian Pharmaceutical Co., Ltd., Jiangsu Hengrui Pharmaceutical Co., Ltd., Shanghai Shanghai Pharmaceutical First Biopharmaceutical Pharmaceutical Co., Ltd., Shandong Fangming Pharmaceutical Group Co., Ltd., Shanghai Shanghai Pharmaceutical Co., Ltd., China Resources Shuanghe Pharmaceutical Co., Ltd., and so on.
summary, that is, a brief information on ketamine.
, ketamine in the whole spiritual field is not a very high degree of attention varieties, but its new drugs, market for decades is still developing the process, it is worth learning from us.
because it is not only a boost to currently unsolt clinical needs, but also a combination of the development company's understanding of the variety and related technologies.
the world has now marketed too many therapeutic drugs, development is not entirely an indisputable fact, and from which to find and carry out better secondary development, perhaps also for the enterprise a drug development strategy.
