Acupan tablets are used to relieve pain, control it, and reduce the severity of pain in all its forms, including general pain relief and treatment of muscle-related pain, such as muscle tension or spasms. They are used to relieve toothache that may result from inflammation or other problems in the mouth. They also play an important role in treating joint pain caused by inflammation or injuries. Acupan tablets contain the active ingredient Nefopam, which is a substance known for its strong pain-relieving properties.
