How Does Tazdol 100mg/2ml Injection 5 vial Work

Tazdol 100mg/2ml Injection 5 vial produces inhibitory effects on the ascending pain pathways by binding to the opioid mu receptors partially (agonistic effect) at the CNS level. Tazdol 100mg/2ml Injection 5 vial also weakly inhibits serotonin and norepinephrine reuptake.

Tazdol 100mg/2ml Injection 5 vial also produces analgesic effects by affecting other pain modulators in the CNS and markers of the inflammation involved in immune responses such as Prostaglandins E2, Cytokines, and Glial cells. This action aids in multiple clinical manifestations which require pain management as a supportive treatment such as osteoarthritis, labor, and postoperative pain.
