==Dosage And Administration==
 
====Hypertension====
 
====Monotherapy====
 
The recommended initial dosage of accupril in patients not on [[diuretics]] is 10 or 20 mg once daily. Dosage should be adjusted according to blood pressure response measured at peak (2–6 hours after dosing) and trough (predosing). Generally, dosage adjustments should be made at intervals of at least 2 weeks. Most patients have required dosages of 20, 40, or 80 mg/day, given as a single dose or in two equally divided doses. In some patients treated once daily, the antihypertensive effect may diminish toward the end of the dosing interval. In such patients an increase in dosage or twice daily administration may be warranted. In general, doses of 40–80 mg and divided doses give a somewhat greater effect at the end of the dosing interval.
 
====Concomitant Diuretics====
 
If blood pressure is not adequately controlled with accupril monotherapy, a [[diuretic]] may be added. In patients who are currently being treated with a diuretic, symptomatic hypotension occasionally can occur following the initial dose of accupril. To reduce the likelihood of [[hypotension]], the diuretic should, if possible, be discontinued 2 to 3 days prior to beginning therapy with accupril. Then, if blood pressure is not controlled with accupril alone, diuretic therapy should be resumed.
 
If the [[diuretic]] cannot be discontinued, an initial dose of 5 mg accupril should be used with careful medical supervision for several hours and until blood pressure has stabilized.
 
The dosage should subsequently be titrated (as described above) to the optimal response.
 
====Renal Impairment====
 
Kinetic data indicate that the apparent elimination half-life of quinaprilat increases as [[creatinine]] clearance decreases. Recommended starting doses, based on clinical and pharmacokinetic data from patients with renal impairment, are as follows:

Patients should subsequently have their dosage titrated (as described above) to the optimal response.
 
====Elderly (≥65 years)====
 
The recommended initial dosage of Accupril in elderly patients is 10 mg given once daily followed by titration (as described above) to the optimal response.
 
====Heart Failure====
 
Accupril is indicated as adjunctive therapy when added to conventional therapy including [[diuretics]] and/or [[digitalis]]. The recommended starting dose is 5 mg twice daily. This dose may improve symptoms of [[heart failure]], but increases in exercise duration have generally required higher doses. Therefore, if the initial dosage of accupril is well tolerated, patients should then be titrated at weekly intervals until an effective dose, usually 20 to 40 mg daily given in two equally divided doses, is reached or undesirable [[hypotension]], [[orthostatis]], or [[azotemia]] prohibit reaching this dose.
 
Following the initial dose of accupril, the patient should be observed under medical supervision for at least two hours for the presence of [[hypotension]] or [[orthostatis]] and, if present, until blood pressure stabilizes. The appearance of [[hypotension]], [[orthostatis]], or [[azotemia]] early in dose titration should not preclude further careful dose titration. Consideration should be given to reducing the dose of concomitant [[diuretics]].
 
====Dose Adjustments in Patients with Heart Failure and Renal Impairment or Hyponatremia====
 
Pharmacokinetic data indicate that quinapril elimination is dependent on level of renal function. In patients with [[heart failure]] and [[renal impairment]], the recommended initial dose of Accupril is 5 mg in patients with a [[creatinine clearance]] above 30 mL/min and 2.5 mg in patients with a creatinine clearance of 10 to 30 mL/min. There is insufficient data for dosage recommendation in patients with a creatinine clearance less than 10 mL/min.
 
If the initial dose is well tolerated, accupril may be administered the following day as a twice daily regimen. In the absence of excessive hypotension or significant deterioration of renal function, the dose may be increased at weekly intervals based on clinical and hemodynamic response.<ref name="dailymed.nlm.nih.gov">{{Cite web  | last =  | first =  | title = ACCUPRIL (QUINAPRIL HYDROCHLORIDE) TABLET, FILM COATED [PARKE-DAVIS DIV OF PFIZER INC] | url = http://dailymed.nlm.nih.gov/dailymed/lookup.cfm?setid=63cf5651-d52c-4d27-9fd4-ed9cd9724dff | publisher =  | date =  | accessdate =  }}</ref>
