Mechanism of action Of Optalidon


  • Caffeine is a central nervous system stimulant that occurs naturally in more than 60 plant species and is used in various foods, drinks and medicines. Caffeine stimulates the medullary, vasomotor and respiratory centers and promotes bradycardia, vasoconstriction and increased respiratory rate. Previously, it was believed that this effect is mainly due to the increase of intracellular cyclic 3 ‘, 5’-adenosine monophosphate (cyclic AMP) after the inhibition of phosphodiesterase, the enzyme that degrades cyclic AMP. Caffeine passes the blood-brain barrier that is supposed to separate the brain from the bloodstream. Once in the brain, caffeine blocks the action of adenosine, which plays an important role in energy transfer and sleep enhancement. Since adenosine acts as an autocoid, it inhibits the release of neurotransmitters from presynaptic sites, but increases the effect of norepinephrine or angiotensin, the antagonism of adenosine receptors promotes the release of neurotransmitters. This explains the stimulating effect of caffeine. The blockade of the adenosine A1 receptor in the heart results in an accelerated and pronounced “heartbeat” of the heart when caffeine is consumed.
  • Propyphenazone is an NSAID derived from pyrazolone and related to phenazone. It has antipyretic and analgesic properties.
