How Do Other Combo Analgesics Work?

How do other combo analgesics work?

Other combo analgesics include different combinations of medications that are used to provide pain relief from common conditions such as headaches and menstrual cramps. Each medication in the combo works in a different way to relieve symptoms such as pain, fever, menstrual cramps, and bloating.

All the combo analgesics contain at least one type of analgesic, either acetaminophen or a non-steroidal anti-inflammatory drug (NSAID). The drug combinations may include other medications such as antihistamines, diuretics, vasoconstrictors, and vitamins.

Each medication used in combo analgesics works in a unique way to relieve inflammatory symptoms. Drugs used in other combo analgesics include:

  • Acetaminophen: Acetaminophen works by blocking the synthesis of prostaglandin in the central nervous system (CNS). Prostaglandin is a fatty compound in the body that has many functions including initiation of inflammation. Acetaminophen also reduces fever by acting on the hypothalamus region of the brain which regulates temperature.
  • NSAIDs: NSAIDs control inflammation by inhibiting the activity of enzymes known as cyclooxygenases (COX-1 and COX-2), essential for the biosynthesis of prostaglandin. NSAIDs reduce blood clotting time, and some NSAIDs such as aspirin are protective against heart disease. NSAIDs also reduce fever by acting on the hypothalamus. NSAIDs used in other combo analgesics include:
  • Caffeine: Caffeine is a vasoconstrictor that constricts cerebral blood vessels, which helps reduce pain in vascular headaches. Caffeine also stimulates the brain’s respiratory drive, improving oxygen inflow.
  • Antihistamines: Antihistamine medications inhibit the activity of histamine, an inflammatory substance naturally released in the body when harmful pathogens are encountered, or in allergies. Antihistamines also have sedative effects. Antihistamines used in other combo analgesics include:
  • Diuretics: Diuretics stimulate increased urination, remove excess fluid from the body and reduce bloating. Diuretic used in other combo analgesics is:
    • Pamabrom
  • Vitamins: Pyridoxine, a vitamin B6 supplement is combined with acetaminophen to reduce its toxic effects on the liver.
  • Misoprostol: Misoprostol is a synthetic prostaglandin combined with diclofenac, an NSAID, to prevent NSAID-induced gastric ulcers.
  • Other medications: Other medications used in combo analgesics include:
