δ14-Triamcinolone acetonide is a potential impurity found in commercial preparations of triamcinolone acetonide. Triamcinolone acetonide is a synthetic corticosteroid. It decreases cytokine levels, the firing rate of sensory neurons, and mechanical hypersensitivity in a rat spinal nerve ligation model when used at a dose of 1.5 mg/kg prior to and following surgery for three days. Triamcinolone acetonide also decreases outflow facility in a mouse model of steroid-induced glaucoma when 20 μl of a 40 mg/ml suspension is administered subconjunctivally. Formulations containing triamcinolone acetonide are used in the treatment of diabetic macular edema.

Naratriptan Hydrochloride is the hydrochloride salt form of naratriptan, a sulfonamide with selective serotonin (5-HT) 1 receptor agonistic activity and anti-migraine property. Naratriptan hydrochloride (GR-85548A hydrochloride) binds selectively and with high affinity to the 5-HT1D and 5-HT1B receptor subtypes. Activation of these 5-HT1D/B receptors located on intracranial blood vessels leads to vasoconstriction and provides relief of migraine headaches. Naratriptan hydrochloride may also exerts its effect by stimulation of 5-HT1D/1B receptors on sensory nerve endings in the trigeminal system thereby decreasing the release of pro-inflammatory neuropeptides.

Melanotan II acetate is an agonist of melanocortin receptor 1 (MC1R), MC3R, MC4R, and MC5R. It has been shown to improve recovery of sciatic nerve function after mechanical injury and increase cisplatin-induced decreases in sensory nerve conduction velocity. Melanotan II acetate increases oxygen consumption and protein levels of uncoupling protein 1 (UCP1) in brown adipose tissue homogenates and decreases food intake, body weight, and serum levels of leptin, glucose, insulin, and cholesterol.

Zolmitriptan (311C90) selectively binds to and activates serotonin (5-HT) 1B receptors expressed in intracranial arteries and 5-HT 1D receptors located on peripheral trigeminal sensory nerve terminals in the meninges and central terminals in brainstem sensory nuclei. Zolmitriptan is a member of the triptan class of agents with anti-migraine properties. Receptor binding results in constriction of cranial vessels, reduction of vessel pulsation and inhibition of nociceptive transmission, thereby providing relief of migraine headaches. Zolmitriptan may also relieve migraine headaches by inhibition of pro-inflammatory neuropeptide release.

Ranirestat (AS-3201) is an orally active and potent aldose reductase (AR) inhibitor with neuroprotective properties that ameliorates peripheral nerve dysfunction in rats with advanced diabetic polyneuropathy.Ranirestat inhibits the inflammatory response of high glucose-exposed endothelial cells and may be useful for the study of diabetic sensory-motor polyneuropathy.

Propoxycaine hydrochloride, an ester local anesthetic, inhibits voltage-gated sodium channels, modulates nerve impulses, and can induce sensory loss.Propoxycaine hydrochloride modulates the flow of lipid bilayers in SPMVs.

CIM0216 is a synthetic TRPM3 activator whose potency and apparent affinity greatly exceeds that of the canonical TRPM3 agonist.
