compounds also inhibit a class of enzymes known as cyclic nucleotide phosphodiesterases. These enzymes are‚ in part responsible for degrading a stimulatory signal produced when excitatory neurotransmitters activate different neurons in the central nervous system (CNS). Thus‚ when they are inhibited by caffeine‚ the stimulatory signal remains active for a longer period of time resulting in a greater sense of alertness (a CNS effect) but also a higher heart rate‚ blood pressure and respiratory rate
