Fiorpap Chemical Information

acetaminophen - An acetanilide with analgesic and antipyretic activity. Although the exact mechanism through which acetaminophen exert its effects has yet to be fully determined, this agent probably acts by inhibiting prostaglandin synthesis in the central nervous system (CNS). Inhibition of prostaglandin synthesis in the CNS results in elevation of the pain threshold and lowering of the thermal set point in the hypothalamus.

butalbital - A barbiturate that exerts its effect by mimicking the inhibitory effect of gamma-aminobutyric acid (GABA) by binding to a site, distinct from the benzodiazepine binding site, on the GABA receptor. This leads to an increase in the duration of GABA-mediated opening of chloride channels and enhances the inhibitory effect of GABA. Consequently, its physiologic effects include sedation, hypnosis, reduction of anxiety, and respiratory depression and the drug causes tolerance and dependence.

caffeine - A naturally occurring xanthine derivative with central nervous system (CNS) stimulating activity. Due to the structural similarity to adenosine, caffeine binds to and blocks adenosine receptors, thereby preventing the inhibitory effects of adenosine on nerve cells. This leads to stimulation of medullary, vagal, vasomotor, and respiratory centers in the brain; and the release of epinephrine. Physiologic responses can include bradycardia, tachycardia, vasoconstriction, CNS excitablility, increased respiratory rate, increased blood pressure, increased blood flow to muscles, decreased blood flow to skin and inner organs, and release of glucose by the liver. Due to the interaction between adenosine A2A and dopamine D2 receptors, caffeine can also indirectly increase the levels of dopamine in the brain.
