Dipyridamole acts by -: (A) Thromboaxne A2 synthesis inhibition, (B) Antagonise the uptake of adenosine by platelet, (C) Calcium channel blocking propey, (D) None
Answer is B. 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 3'5' monophosphate. o This effect is mediated by inhibition of cyclic nucleotide phosphodiesterase or by blockade of uptake of adenosine.
