What is the neurology mechanism during drug intake ?
In: Chemistry
That’s way too broad a question because different drugs have different mechanisms of acting on the body, but essentially drugs interact with endogenous (built in) signaling pathways in the body such as neurotransmitters and their receptors. To use one example, caffeine is shaped kind of like a neurotransmitter called adenosine that builds up throughout the day and acts on adenosine receptors to trigger sleepiness. Caffeine is shaped closely enough to fit in the receptors but not closely enough to actually activate them, so like a key that fits in the keyhole but can’t turn the lock, caffeine blocks adenosine from doing its thing, leading to us feeling more alert.
