Sedalmerck is a Mexican combination pain medication that contains caffeine, acetaminophen and phenylephrine as active ingredients. This medication is used to treat headaches, fever, pain, and to treat nose stuffiness.
Caffeine is a stimulant, which means it increases activity in your brain and nervous system. Studies show that caffeine helps drugs like acetaminophen be 5-10 percent more effective at relieving pain. Caffeine helps reduce the way the brain perceives pain, while boosting the production of dopamine, which acts as a natural painkiller.
Acetaminophen relieves pain by elevating the pain threshold, that is, by requiring a greater amount of pain to develop before a person feels it. It reduces fever through its action on the heat-regulating center of the brain. While phenylephrine works by directly stimulating alpha-1 adrenergic receptors in the arteries causing vasoconstriction (narrowing of the blood vessels). This reduces nasal congestion by preventing fluid from draining from the blood vessels into the tissues lining the nasal passages.
