Which of the following is not a therapeutic use of gabapentin?

Gabapentin is primarily utilized for several neurological conditions, including neuropathic pain management, epilepsy control, and treatment of conditions like restless leg syndrome. Its mechanism of action involves modulating neurotransmitter release and altering neuronal excitability, which helps alleviate symptoms in these conditions.

In contrast, gabapentin is not approved for the treatment of insomnia. While some individuals may experience improved sleep as a secondary effect of neuropathic pain relief or anxiety reduction, it is not specifically indicated or utilized as a sleep aid. Therefore, the use of gabapentin for insomnia does not align with its recognized therapeutic applications, making it clear that this is not one of its intended uses.
