Nefopam and its Role in Modulating Acute and Chronic Pain

Pain is a very important issue to take into account during hospitalization. Nefopam, a centrally acting analgesic, has a relative safety pharmacological profile with few and well-tolerated side effects, being used to treat acute or chronic pain. It inhibits the central reuptake of serotonin, norepinephrine and dopamine and modulates the sodium and calcium channels having only few contraindications. Nefopam can be part of balanced analgesia along with others non-opioids agents in order to reduce the opioid consumption and their complications, to control postoperative pain and to reduce the risk of neuropathic pain appearance. In order to avoid its adverse reactions, a slow infusion is always recommended. Nefopam has its role in preventing the shivering appearance during neuraxial or general anesthesia, can modulate the emergence agitation after nasal and maxillofacial surgery and can inhibit the sever hiccup during mechanical ventilation. Some cases about fatal overdoses are reported in the literature.
