<P>Fasting blood glucose was determined in 27 adults with essential hypertension at four different periods during a 12-month treatment with doxazosin, an alpha-adrenoceptor antagonist, and in another set of 20 adult hypertensive patients, after 3 months treatment with amlodipine, a calcium antagonist. The mean fasting blood glucose levels at various determinations during doxazosin therapy did not show any significant variation from the pre-treatment value. Similarly, mean fasting blood glucose level remained the same after 3 months of amlodipine therapy. The findings, therefore, highlights the safety of doxazosin and amlodipine antihypertensive pharmacotherapies.</P></p
