Hypertension: Perinace may be used in monotherapy or in combination with other classes of antihypertensive therapy (see CONTRAINDICATIONS, INTERACTIONS, PRECAUTIONS and PHARMACOLOGY: PHARMACODYNAMICS under ACTIONS).
The recommended starting dose is 4 mg given once daily in the morning.
Patients with a strongly activated renin-angiotensin-aldosterone system (in particular, renovascular hypertension, salt and/or volume depletion, cardiac decompensation or severe hypertension) may experience an excessive drop in blood pressure following the initial dose. A starting dose of 2 mg is recommended in such patients and the initiation of treatment should take place under medical supervision.
The dose may be increased to 8 mg once daily after one month of treatment.
Symptomatic hypotension may occur following initiation of therapy with Perinace; this is more likely in patients who are being treated concurrently with diuretics. Caution is therefore recommended since these patients may be volume and/or salt depleted.
If possible, the diuretic should be discontinued 2 to 3 days before beginning therapy with Perinace (see PRECAUTIONS).
In hypertensive patients in whom the diuretic cannot be discontinued, therapy with Perinace should be initiated with a 2 mg dose. Renal function and serum potassium should be monitored. The subsequent dosage of Perinace should be adjusted according to blood pressure response. If required, diuretic therapy may be resumed.
In elderly patients, treatment should be initiated at a dose of 2 mg which may be progressively increased to 4 mg after one month then to 8 mg if necessary, depending on renal function (see table as follows).
Symptomatic heart failure: It is recommended that Perinace, generally associated with a non-potassium-sparing diuretic and/or digoxin and/or a beta-blocker, be introduced under close medical supervision with a recommended starting dose of 2 mg taken in the morning. This dose may be increased after 2 weeks to 4 mg once daily if tolerated. The dose adjustment should be based on the clinical response of the individual patient.
In severe heart failure and in other patients considered to be at high risk (patients with impaired renal function and a tendency to have electrolyte disturbances, patients receiving simultaneous treatment with diuretics and/or treatment with vasodilating agents), treatment should be initiated under careful supervision (see PRECAUTIONS).
Patients at high risk of symptomatic hypotension e.g., patients with salt depletion with or without hyponatraemia, patients with hypovolaemia or patients who have been receiving vigorous diuretic therapy should have these conditions corrected, if possible, prior to therapy with Perinace.
Blood pressure, renal function and serum potassium should be monitored closely, both before and during treatment with Perinace (see PRECAUTIONS).
Stable coronary artery disease: Perinace should be introduced at a dose of 4 mg once daily for two weeks, then increased to 8 mg once daily, depending on renal function and provided that the 4 mg dose is well tolerated.
Elderly patients should receive 2 mg once daily for one week, then 4 mg once daily the next week, before increasing the dose up to 8 mg once daily depending on renal function (see Table 1 "Dosage adjustment in renal impairment"). The dose should be increased only if the previous lower dose is well tolerated.
Special population: Patients with renal impairment: Dosage in patients with renal impairment should be based on creatinine clearance as outlined in table 1 as follows: (See Table 1).

Patients with hepatic impairment: No dosage adjustment is necessary in patients with hepatic impairment (see PRECAUTIONS and PHARMACOLOGY: PHARMACOKINETICS under ACTIONS).
Paediatric population: The safety and efficacy of perindopril in children and adolescents aged below 18 years have not been established.
Therefore, use in children and adolescents is not recommended.
METHOD OF ADMINISTRATION: Perinace is recommended to be taken once daily in the morning before a meal.
ROUTE OF ADMINISTRATION: Oral.
