Sympathomimetic drugs are used in all of the conditions, except:: (A) High blood pressure, (B) Acute uncompensated cardiac failure, (C) Low blood pressure, (D) Erectile dysfunction
Answer is D. Erection is mediated parasympathetic stimuli, while ejaculation is under control of sympathomimetic agents. Thus sympathomimetic agents will not help in erectile dysfunction.
