ACE inhibitor Pregnancy: Not recommended during the first trimester of pregnancy and contraindicated during the second and third trimesters. Stop treatment immediately when pregnancy is diagnosed and start alternative therapy if appropriate. Second and third trimester exposure is known to induce human foetotoxicity (decreased renal function, oligohydramnios, skull ossification retardation) and neonatal toxicity (renal failure, hypotension, hyperkalaemia); if exposure occurred from the second trimester, ultrasound check of renal function and skull is recommended and infants should be closely observed for hypotension. Not recommended during breast-feeding (eMC 4.6).

Perindopril arginine

Brand names: Coversyl Arginine

Perindopril arginine is a once-daily ACE inhibitor used for hypertension, stable coronary artery disease and chronic heart failure.

Auto-extracted from the source labelling — not yet independently clinician-verified. These values were distilled from the UK SPC (or the US label where noted) but have not had a clinician sign-off. Confirm against the current SmPC before prescribing.

Adult dose

Dose: Hypertension: 5 mg (recommended starting dose)
Route: Oral
Frequency: Once daily in the morning, before a meal
Max: 10 mg once daily
eMC SPC 4.2 (Coversyl Arginine 10 mg Film-coated Tablets). The dose should be individualised according to the patient profile and blood pressure response; the dose may be increased to 10 mg once daily after one month of treatment. A starting dose of 2.5 mg is recommended, with initiation under medical supervision, in patients with a strongly activated renin-angiotensin-aldosterone system (in particular renovascular hypertension, salt and/or volume depletion, cardiac decompensation or severe hypertension). Symptomatic hypotension may occur after initiation, more likely in patients concurrently treated with diuretics - if possible discontinue the diuretic 2 to 3 days before starting; where the diuretic cannot be discontinued, initiate at 2.5 mg and monitor renal function and serum potassium, adjusting subsequent dosage according to blood pressure response. ELDERLY (hypertension): initiate at 2.5 mg, increase progressively to 5 mg after one month, then to 10 mg if necessary depending on renal function. SYMPTOMATIC HEART FAILURE: recommended starting dose 2.5 mg taken in the morning, introduced under close medical supervision and generally associated with a non-potassium-sparing diuretic and/or digoxin and/or a beta-blocker; may be increased after 2 weeks to 5 mg once daily if tolerated, adjusted to the individual clinical response. In severe heart failure and other high-risk patients (impaired renal function with a tendency to electrolyte disturbance, concurrent diuretics and/or vasodilators) initiate under careful supervision; correct salt depletion, hyponatraemia or hypovolaemia beforehand if possible and monitor blood pressure, renal function and serum potassium closely before and during treatment. STABLE CORONARY ARTERY DISEASE: 5 mg once daily for two weeks, then increased to 10 mg once daily depending on renal function and provided the 5 mg dose is well tolerated; elderly patients should receive 2.5 mg once daily for one week, then 5 mg once daily the next week, before increasing up to 10 mg once daily depending on renal function. Increase the dose only if the previous lower dose is well tolerated. HEPATIC IMPAIRMENT: no dosage adjustment is necessary. PAEDIATRIC: safety and efficacy in children and adolescents aged below 18 years have not been established; no recommendation on a posology can be made and use in children and adolescents is not recommended - no per-kg dose is stated; refer to a children's formulary. NOTE: the fetched extract does not include SPC section 4.5, so the interaction list below is drawn only from sections 4.2/4.3/4.4 and is incomplete - clinician to check the full interaction section.

Dose adjustments

Renal

Dose based on creatinine clearance (SPC Table 1): ClCR >= 60 ml/min - 5 mg per day; 30 < ClCR < 60 ml/min - 2.5 mg per day; 15 < ClCR < 30 ml/min - 2.5 mg every other day; haemodialysed patients with ClCR < 15 ml/min - 2.5 mg on the day of dialysis, taken after dialysis (dialysis clearance of perindoprilat is 70 ml/min).

Contraindications

  • Hypersensitivity to the active substance, to any of the excipients or to any other ACE inhibitor
  • History of angioedema associated with previous ACE inhibitor therapy; hereditary or idiopathic angioedema
  • Second and third trimesters of pregnancy
  • Concomitant use with aliskiren-containing products in patients with diabetes mellitus or renal impairment (GFR < 60 ml/min/1.73 m2)
  • Concomitant use with sacubitril/valsartan therapy - must not be initiated earlier than 36 hours after the last dose of sacubitril/valsartan
  • Extracorporeal treatments leading to contact of blood with negatively charged surfaces
  • Significant bilateral renal artery stenosis or stenosis of the artery to a single functioning kidney

Side effects

  • Dizziness, headache, paraesthesia, vertigo (common)
  • Cough, dyspnoea (common)
  • Hypotension and effects related to hypotension (common)
  • Gastrointestinal: abdominal pain, constipation, diarrhoea, dysgeusia, dyspepsia, nausea, vomiting (common)
  • Pruritus and rash (common); angioedema of face, extremities, lips, mucous membranes, tongue, glottis and/or larynx, and urticaria (uncommon)
  • Hyperkalaemia (reversible on discontinuation), hyponatraemia and hypoglycaemia (uncommon); visual disturbances and tinnitus (common)

Interactions

  • Aliskiren-containing products - contraindicated in patients with diabetes mellitus or renal impairment (GFR < 60 ml/min/1.73 m2) (SPC 4.3)
  • Sacubitril/valsartan - contraindicated; do not initiate perindopril earlier than 36 hours after the last dose (SPC 4.3)
  • Diuretics - symptomatic hypotension is more likely; discontinue the diuretic 2 to 3 days before starting if possible, otherwise initiate at 2.5 mg with monitoring of renal function and serum potassium (SPC 4.2/4.4)
  • Extracorporeal treatments leading to contact of blood with negatively charged surfaces - contraindicated (SPC 4.3)
  • NOTE: eMC 4.5 was not captured in this bundle - the entries above come from SPC 4.2/4.3/4.4 only. Clinician to review the full 4.5 before publication.

Clinical monograph

How it works

It is a prodrug converted to perindoprilat, which inhibits angiotensin-converting enzyme to reduce angiotensin II and aldosterone, lowering vascular resistance and fluid retention.

Prescribing in practice

  • Check renal function and potassium before starting and after dose changes, and be alert to first-dose hypotension in diuretic-treated or volume-depleted patients.
  • Dry cough and, rarely, angioedema can occur; hyperkalaemia is a recognised risk.
  • Avoid in pregnancy and in bilateral renal artery stenosis; use caution in renal impairment and with other potassium-raising agents.

Monitoring

Monitor renal function, serum potassium and blood pressure before treatment, after dose adjustments and periodically during therapy.

Counselling the patient

  • Take it at the same time each day, ideally before food in the morning.
  • Report a persistent dry cough or any swelling of the face, lips or throat (seek urgent help), and avoid potassium-based salt substitutes.
