DURACLON (clonidine hydrochloride)

Oncology Approved 1996-10-02

Duraclon is indicated for use in combination with opioid analgesics to treat severe pain in cancer patients. It is specifically intended for patients whose pain is not adequately managed by opioids alone and is more likely to be effective for neuropathic pain than somatic or visceral pain. The safety of this medication has been established only in this specific patient population following an adequate trial of opioid analgesia.

How DURACLON Works

Administered epidurally, clonidine produces analgesia by targeting presynaptic and postjunctional alpha-2-adrenoceptors in the spinal cord. By activating these receptors, the drug prevents the transmission of pain signals from the spinal cord to the brain. This effect is dose-dependent and localized to the body regions innervated by the specific spinal segments where the medication is present.
