<prompt> Dipyridamole acts by -Thromboaxne A2 synthesis inhibitionAntagonise the uptake of adenosine by plateletCalcium channel blocking propeyNone  <response>: Ans. is b i.e., Antagonise the uptake of adenosine by platelet Antiplatelet action of dipvridamole o Dipyridamole interferes with platelet function by increasing the cellular concentration of adenosine 35 monophosphate. o This effect is mediated by inhibition of cyclic nucleotide phosphodiesterase or by blockade of uptake of adenosine.
