Zobox Uses, Dosage, Side Effects, Food Interaction and all others data.

Zobox is an ACE inhibtor class drug used in the treatment of hypertension and heart failure. It belongs to the angiotensin-converting enzyme inhibitors (ACE inhibitors) class of drugs. It is a prodrug that is hydrolyzed after absorption to its main metabolite cilazaprilat. It is branded as Inhibace in Canada and other countries, Vascace and Dynorm in a number of European countries, among many other names. None of these varieties are available in the United States.

Zobox inhibits the production angiotensin II. By doing so, it decreases sodium and water reabsorption (via aldosterone) and it decreases vasoconstriction. The combined effect of this is a decrease in vascular resistance, and therefore, blood pressure. The absolute bioavailability of cilazaprilat after oral administration of cilazapril is 57% based on urinary recovery data. (The absolute bioavailability of cilazaprilat after oral administration of cilazaprilat is 19%.) Ingestion of food immediately before the administration of cilazapril reduces the average peak plasma concentration of cilazaprilat by 29%, delays the peak by one hour and reduces the bioavailability of cilazaprilat by 14%. These pharmacokinetic changes have little influence on plasma ACE inhibition.

Protein binding	Maximum ACE inhibition is greater than 90% after 1 to 5 mg cilazapril. Maximum ACE inhibition is 70 to 80% after 0.5 mg cilazapril. Dose proportionality is observed following the administration of 1 to 5 mg cilazapril. Apparent non-proportionality is observed at 0.5 mg reflective of the binding to ACE. The higher doses of cilazapril are associated with longer duration of maximum ACE inhibition.

Uses

Zobox is an ACE inhibitor used for the management of hypertension and heart failure.

Zobox is an ACE inhibtor class drug used in the treatment of hypertension and heart failure.

Zobox is also used to associated treatment for these conditions: Congestive Heart Failure (CHF), High Blood Pressure (Hypertension), Mild Essential Hypertension, Moderate Essential Hypertension

How Zobox works

Zobox is a pyridazine ACE inhibitor. It competes with angiotensin I for binding at the angiotensin-converting enzyme, blocking the conversion of angiotensin I to angiotensin II. As angiotensin II is a vasoconstrictor and a negative feedback mediator for renin activity, lower angiotensin II levels results in a decrease in blood pressure, an increase in renin activity, and stimulation of baroreceptor reflex mechanisms. Kininase II, an enzyme which degrades the vasodilator bradykinin, is identical to ACE and may also be inhibited.

Toxicity

Limited data are available with regard to overdosage in humans. The most likely manifestations are hypotension, which may be severe, hyperkalaemia, hyponatraemia and renal impairment with metabolic acidosis. Treatment should be mainly symptomatic and supportive.

Food Interaction

Take with or without food. Food decreases absorption, but not to a clinically significant extent.

Elimination Route

Maximum plasma concentrations of cilazaprilat are reached within two hours after administration of cilazapril.

Half Life

Half-lives for the periods 1 to 4 hours and 1 to 7 days after the intravenous administration of 2.5 mg cilazaprilat are 0.90 and 46.2 hours respectively.

Clearance

Total clearance is 12.3 L/h and renal clearance is 10.8 L/h. The total urinary recovery of cilazaprilat following the oral administration of 2.5 mg cilazapril is 52.6%.
