4.2 Drug Indication

Investigated for use/treatment in pain (acute or chronic).


5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Cyclooxygenase Inhibitors

Compounds or agents that combine with cyclooxygenase (PROSTAGLANDIN-ENDOPEROXIDE SYNTHASES) and thereby prevent its substrate-enzyme combination with arachidonic acid and the formation of eicosanoids, prostaglandins, and thromboxanes. (See all compounds classified as Cyclooxygenase Inhibitors.)


Anti-Inflammatory Agents, Non-Steroidal

Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects. (See all compounds classified as Anti-Inflammatory Agents, Non-Steroidal.)


5.2 FDA Pharmacological Classification
5.2.1 Pharmacological Classes
Cyclooxygenase Inhibitor [EPC]; Cyclooxygenase Inhibitors [MoA]; Nonsteroidal Anti-inflammatory Drug [EPC]; Anti-Inflammatory Agents, Non-Steroidal [CS]
5.3 Mechanism of Action

ROX-888 is a intranasal formulation of the broadly used injectible analgesic, ketorolac. It has ability to provide effective analgesia in acute medical conditions resulting in moderate-severe pain, without the disabling side effects of opioid analgesics
