Mechanism of Action

Ramipril and Ramiprilat inhibit angiotensin-converting enzyme (ACE) in human subjects and animals. ACE is a peptidyl dipeptides that catalyzes the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. Angiotensin II also stimulates aldosterone secretion by the adrenal cortex. Inhibition of ACE results in decreased plasma angiotensin II, which leads to decreased vasopressor activity and to decreased aldosterone secretion. The latter decrease may result in a small increase of serum potassium.

ACE is identical to kininase, an enzyme that degrades bradykinin. Whether increased levels of bradykinin, a potent vasodepressor peptide, play a role in the therapeutic effects of Ramipril remains to be elucidated.

While the mechanism through which Ramipril lowers blood pressure is believed to be primarily suppression of the renin-angiotensin-aldosterone system, Ramipril has an antihypertensive effect even in patients with low-renin hypertension.


Following oral administration of BioRamipril, peak plasma concentrations of Ramipril are reached within one hour. The extent of absorption is at least 50-60% and is not significantly influenced by the presence of food in the GI tract, although the rate of absorption is reduced.

Peak plasma concentrations of ramiprilat are reached 2-4 hours after drug intake. The serum protein binding of ramipril is about 73% and that of ramiprilat about 56%.

Ramipril is almost completely metabolized to ramiprilat, which has about 6 times the ACE inhibitory activity of ramipril, and to inactive metabolites. After oral administration of ramipril, about 60% of the parent drug and its metabolites is eliminated in the urine, and about 40% is found in the feces (may represent both biliary excretion of metabolites and/or unabsorbed drug).

Blood concentrations of ramipril and ramiprilat increase with increased dose. After multiple daily doses of ramipril 5-10 mg, the half-life of ramiprilat concentrations within the therapeutic range was 13-17 hours.

After once-daily dosing, steady-state plasma concentrations of ramiprilat are reached by the fourth dose.

In patients with creatinine clearance less than 40 ml/min/1.73m 2 , peak levels of ramiprilat are approximately doubled.

In patients with impaired liver function, the metabolism of ramipril to ramiprilat appears to be slowed, and plasma ramipril levels are increased .

Bioramipril  must not be used in patients with

  • Hypersensitive to this product or any other angiotensin converting enzyme inhibitor .
  • A history of angioneurotic oedema .
  • Blood flow reducing . narrowing  (haemodynamically relevant stenosis ) of the renal artery, bilateral or unilateral in the single kidney ( risk of fall in blood pressure and renal failure )





Side effects :

Please tell your physician or pharmacist if you experience any adverse effect with the use of Bioramipril

  • Commonly , a dry cough occur.
  • Uncommonly, mild symptoms and reactions such as headache , disorders of balance , tachycardia , weakness  drowsiness may occur
  • Rarely, mild symptoms such as peripheral oedema., flushing, dizziness , tinnitus , fatigue , nervousness  , nausea, depressed mood, tremor , restlessness , visual disturbances , sleep disturbances , pruritus, or rash, dry mouth , diarrhea, dyspepsia may occur .

Warnings & Precautions

Treatment with Bioramipril requires regular medical supervision.

·        If angioneurotic odema  occurs during treatment, Bioramipril must be discontinued immediately and if the tongue, glottis, or larynx  are involved emergency measures taken .

  • Significant activation of the rennin angiotensin system is to be expected. The initial phase of treatment requires special medical supervision , for example, in patients :
  • With severe, and particularly with malignant hypertension.
  •  With heart failure, particularly if severe or if treated with other potentially blood pressure lowering medicines.
  • With blood flow reducing (haemodynamically relevant ) left ventricular inflow or outflow impediment.
  •  Narrowing(haemodynamically relevant stenosis)of the renal artery. Concomitant treatment with a diuretic may have to be discontinued .
  • Pre-treated with diuretics. Where discontinuation or reduction of the dose of the diuretic is not possible.
  • In whom fluid or salt deficiency exist or may develop . Generally, dehydration,reduced blood volume

  ( hypovolaemia) , or salt deficiency should be corrected before initiating treatment .

  • In patients with impaired liver function , response to treatment with Bioramipril may be either increased or reduced . In addition, in patients with severe liver cirrhosis with oedema and/or ascites, the rennin angiotensin system may be significantly activated therefore, particular caution must be exercised in treating such patients.
  • Renal function should  be  evaluated at the beginning of treatment in elderly patients.
  • Renal function should  be monitored in patients with heart failure, in patients with renovascular  disease, in patients with impairment of renal function , or in kidney transplant patients.
  •  Serum potassium should be monitored regularly . particularly , in patients with impaired renal function.
  • White blood cell counts should be monitored so that a possible excessive reduction in white blood cells  

    ( leucopenia ) can be detected.

Pregnancy & lactation :

Bioramipril  must not be taken during pregnancy . Otherwise there is a risk of harm to the fetus.

Lactation, breast-feeding must be avoided  during treatment with Bioramipril .

Drug Interactions

Nonsteroidal anti-inflammatory agents:    Rarely, concomitant treatment with ACE inhibitors and nonsteroidal anti-inflammatory agents have been associated with worsening of renal failure and an increase in serum potassium.

Diuretics:    Patients on diuretics, especially those in whom diuretic therapy was recently instituted, may occasionally experience an excessive reduction of blood pressure after initiation of therapy with ramipril. The possibility of hypotensive effects with ramipril can be minimized by either discontinuing the diuretic or increasing the salt intake prior to initiation of treatment with ramipril. If this is not possible, the starting dose should be reduced.

Potassium supplements and Potassium-sparing diuretics:    Ramipril can attenuate potassium loss caused by thiazide diuretics. Potassium-sparing diuretics (spironolactone, amiloride, triamterene, and others) or potassium supplements can increase the risk of hyperkalemia. Therefore, if concomitant use of such agents is indicated, they should be given with caution, and the patient's serum potassium should be monitored frequently.







Lithium:    Increased serum lithium levels and symptoms of lithium toxicity have been reported in patients receiving ACE inhibitors during therapy with lithium. These drugs should be coadministered with caution, and frequent monitoring of serum lithium levels is recommended. If a diuretic is also used, the risk of lithium toxicity may be increased.

Other:    Neither ramipril nor its metabolites have been found to interact with food, digoxin, antacid, furosemide, cimetidine, indomethacin, and simvastatin. The combination of ramipril and propranolol showed no adverse effects on dynamic parameters (blood pressure and heart rate). The co-administration of ramipril and warfarin did not adversely affect the anticoagulant effects of the latter drug.


Overdose may cause excessive peripheral vasodilatation ( with marked hypotension, shock ) bradycardia , electrolyte disturbances , and renal failure .

Treatment or Management of Overdose

Primary detoxification : gastric lavage , administration of adsorbents , sodium sulfate ( if possible during the first 30 minutes ) . In case of hypotension , administration of ( 1- adrenergic agonists and  angiotensin II) must be considered ,in addition to volume and salt  substitution .
