<prompt> All of the following drug can be used in hypeensive crisis except: September 2007LabetalolPindololNitroprussideNone  <response>: Ans. B: Pindolol Hypeensive emergencies are treated in an ICU; BP is progressively although not abruptly reduced using a sho-acting, titratable IV drug. Choice of drug and speed and degree of reduction vary somewhat with the target organ involved, but generally a 20 to 25 reduction in MAP over an hour or so is appropriate, with fuher titration based on symptoms. Achieving normal BP urgently is not necessary. Typical first-line drugs include Nitroprusside Fenoldopam Nicardipine Labetalol Oral drugs are not indicated because onset is variable and the drugs are difficult to titrate. Sho-acting oral nifedipine reduces BP rapidly, it may lead to acute cardiovascular and cerebrovascular events sometimes fatal and is therefore not recommended.
