The use of sublingual captopril has been recently suggested in hypertensive crisis on the assumption of a faster absorption and thus a more rapid effect on blood pressure than with the oral route. To verify this hypothesis we have compared the hypotensive effect of oral and sublingual captopril in 40 essential hypertensives who were randomly allocated to either route of administration. Captopril was administered orally dissolved in water or allowed to dissolve under the tongue. After 5, 10, 20, 30, 40, 60 and 90 minutes blood pressure, Plasma Renin Activity (PRA) and Angiotensin Converting Enzyme (ACE) were measured. No significant differences were found between the two groups in the time course of blood pressure decrease, PRA increase and ACE inhibition. The changes of the parameters studied was superimposable irrespective of the route of administration thus not supporting the hypothesis that sublingual captopril might be absorbed more rapidly.

Abstract
The use of sublingual captopril has been recently suggested in hypertensive crisis on the assumption of a faster absorption and thus a more rapid effect on blood pressure than with the oral route. To verify this hypothesis we have compared the hypotensive effect of oral and sublingual captopril in 40 essential hypertensives who were randomly allocated to either route of administration. Captopril was administered orally dissolved in water or allowed to dissolve under the tongue. After 5, 10, 20, 30, 40, 60 and 90 minutes blood pressure, Plasma Renin Activity (PRA) and Angiotensin Converting Enzyme (ACE) were measured. No significant differences were found between the two groups in the time course of blood pressure decrease, PRA increase and ACE inhibition. The changes of the parameters studied was superimposable irrespective of the route of administration thus not supporting the hypothesis that sublingual captopril might be absorbed more rapidly.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
