Ketamine.

Ketamine is a very versatile inexpensive drug and plays an invaluable role in the developing world. In regions where access and funding for a wider range of drugs is problematic, its broad range of clinical applications is ideal. Its good safety profile and ease of storage makes it ideal for use in areas where refrigerators, complex monitoring, electricity and oxygen may all be in short supply or unreliable. Ketamine is also finding increasing use in both the acute and chronic pain settings and research is still ongoing into a potential neuroprotective effect for ketamine in brain injury.
