What is Tramadol SR 100mg?

Tramadol SR (Sustained Release) 100 mg is an opioid painkiller that changes how the brain and nervous system understand pain. The “SR” in the drug’s name indicates its gradual release in the body over time. This type of medication gives longer-lasting pain relief than immediate-release forms.

How Does Tramadol SR 100mg Work?

Tramadol works by attaching to opioid receptors in the brain. These receptors send signals about pain.

Because it works in two ways, Tramadol can help with both short-term and long-term pain.
