• Description: Eptazocine hydrobromide is a centrally-acting analgesic useful in the management of post-operative and cancer pain, In animal studies eptazocine exhibits a mixed agonist/antagonist profile; its analgesic activity is reported to be mediated via opiate receptors and catecholaminergic neurons.
• Uses: Eptazocine Hydrobromide (CAS# 72150-17-5) can be used for various pharmaceutical compounds for improved skin penetration for opioid antagonists due to the presence of fatty acid esters and glycerin fatty acid esters.
