DB01348 - Spirapril


Identification
Name Spirapril
Accession Number DB01348
Type small molecule
Description Spirapril is an ACE inhibitor antihypertensive drug used to treat hypertension. Like many ACE inhibitors, this is a prodrug which is converted to the active metabolite spiraprilat following oral administration. ACE inhibitors are used primarily in treatment of hypertension and congestive heart failure.

Pharmacology
Indication Spirapril is an ACE inhibitor class drug used to treat hypertension.
Mechanism of action Spiraprilat, the active metabolite of spirapril, competes with angiotensin I for binding at the angiotensin-converting enzyme, blocking the conversion of angiotensin I to angiotensin II. Inhibition of ACE results in decreased plasma angiotensin II. As angiotensin II is a vasoconstrictor and a negative-feedback mediator for renin activity, lower concentrations result in a decrease in blood pressure and stimulation of baroreceptor reflex mechanisms, which leads to decreased vasopressor activity and to decreased aldosterone secretion. Spiraprilat may also act on kininase II, an enzyme identical to ACE that degrades the vasodilator bradykinin.
Absorption Bioavailability is 50% following oral administration.
Protein binding Not Available
Biotransformation Hepatic. Converted to spiraprilat following oral administration.
Route of elimination Not Available
Toxicity Not Available

Interactions
Drug Interactions
Drug Mechanism of interaction
Amiloride Increased risk of hyperkalemia
Lithium The ACE inhibitor increases serum levels of lithium
Potassium Increased risk of hyperkalemia
Tizanidine Tizanidine increases the risk of hypotension with the ACE inhibitor
Triamterene Increased risk of hyperkalemia
Food Interactions
  • Herbs that may attenuate the antihypertensive effect of spirapril include: bayberry, blue cohash, cayenne, ephedra, ginger, ginseng (American), kola and licorice.
  • High salt intake may attenuate the antihypertensive effect of spirapril.
  • Spirapril may decrease the excretion of potassium. Salt substitutes containing potassium may increase the risk of hyperkalemia.
  • Avoid alcohol.
  • Do not take calcium, aluminum, magnesium or Iron supplements within 2 hours of taking this medication.
