Lotensin Indication:

For the treatment of hypertension. It may be used alone or in combination with thiazide diuretics.

Lotensin Mechanism Of Action:

Lotensinat, the active metabolite of Lotensin, 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. Lotensinat may also act on kininase II, an enzyme identical to ACE that degrades the vasodilator bradykinin.

Lotensin Drug Interactions:

Amiloride Increased risk of hyperkaliemia
Potassium Increased risk of hyperkaliemia
Lithium The ACE inhibitor increases serum levels of lithium
Spironolactone Increased risk of hyperkaliemia
Triamterene Increased risk of hyperkaliemia
Tizanidine Tizanidine increases the risk of hypotension with the ACE inhibitor
Drospirenone Increased risk of hyperkaliemia

Lotensin Food Interactions:

Take without regard to meals.
Food slows absorption without decreasing the quantity absorbed.

Lotensin Generic Name:


  • Not Available

Drug Type:

Small Molecule; Approved


Peak in plasma within 0.5-1.0 hours. The extent of absorption is at least 37% as determined by urinary recovery and is not significantly influenced by the presence of food in the GI tract.

Toxicity (Overdose):

Symptoms of overdose include swelling of face, mouth, hands, or feet, trouble in swallowing or breathing (sudden), hoarseness, fever and chills.

Protein Binding:



Cleavage of the ester group (primarily in the liver) converts benazepril to its active metabolite, benazeprilat.

Half Life:

10-11 hours

Dosage Forms of Lotensin:

Tablet Oral
