SIDE EFFECTS

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

In an active-controlled 6-week trial, the safety of the maximum dose of PRESTALIA (14/10 mg) was evaluated in 279 patients with hypertension and compared with perindopril erbumine 16 mg and amlodipine 10 mg. Adverse reactions were generally mild and transient in nature.

Discontinuations because of adverse events occurred in 3.6% of patients treated with PRESTALIA 14/10 mg compared to 4.3% of patients treated with perindopril erbumine 16 mg and 4.6% of patients treated with amlodipine 10 mg. The most common reason for discontinuation of therapy with PRESTALIA was peripheral edema (1.8%).

Common adverse events that occurred in at least 2% of patients treated with PRESTALIA in the 6-week trial are presented in Table 1.

Table 1: Adverse Reactions Occurring at an Incidence of ≥2% in PRESTALIA-Treated Patients

Adverse Event	PRESTALIA 14/10 mg (N = 279) n (%)	PERe 16 mg (N = 278) n (%)	AML 10 mg (N = 280) n (%)
Edema peripheral	20 (7.2)	1 (0.4)	37 (13.2)
Cough	9 (3.2)	8 (2.9)	2 (0.7)
Headache	7 (2.5)	8 (2.9)	8 (2.9)
Dizziness	7 (2.5)	4 (1.4)	3 (1.1)
PERe = perindopril erbumine; AML = amlodipine besylate

 

The overall frequency of adverse reactions was similar between men and women, and black and non-black patients. In black patients, the incidence of peripheral edema was similar in the PRESTALIA 14/10 mg and amlodipine 10 mg arms (3%).

Other adverse reactions in the controlled clinical trial with some plausible relationship to PRESTALIA are listed below.

Dermatologic: Rash 

Digestive: Nausea, diarrhea

The safety of the lowest dose of PRESTALIA (3.5/2.5 mg) was evaluated in 249 patients with hypertension and compared with placebo and perindopril and amlodipine administered as monotherapies in an 8-week trial. The only emergent adverse event observed in at least 2% of patients treated with PRESTALIA was hyperkalemia (2.4%). Peripheral edema was reported in 1.6% of patients receiving PRESTALIA 3.5/2.5 mg.

Monotherapy with perindopril or amlodipine has been evaluated for safety in clinical trials in over 3,000 and 11,000 patients, respectively, as summarized below.

Perindopril

Perindopril erbumine has been evaluated for safety in approximately 3,400 patients with hypertension in U.S. and foreign clinical trials. The data presented here are based on results from the 1,417 perindopril-treated patients who participated in the U.S. clinical trials. Over 220 of these patients were treated with perindopril for at least one year.

In placebo-controlled U.S. clinical trials, the incidence of premature discontinuation of therapy due to adverse events was 6.5% in patients treated with perindopril erbumine and 6.7% in patients treated with placebo. The most common causes were cough, headache, asthenia, and dizziness.

Among 1,012 patients in placebo-controlled U.S. trials, the overall frequency of reported adverse events was similar in patients treated with perindopril erbumine and in those treated with placebo (approximately 75% in each group). The only adverse events whose incidence on perindopril erbumine was at least 2% greater than on placebo were cough (12% vs. 4.5%) and back pain (5.8% vs. 3.1%).

Dizziness was not reported more frequently in the perindopril group (8.2%) than in the placebo group (8.5%), but its likelihood increased with dose, suggesting a causal relationship with perindopril.

Amlodipine

Amlodipine has been evaluated for safety in more than 11,000 patients in U.S. and foreign clinical trials. In controlled clinical trials comparing amlodipine (N=1730) in doses up to 10 mg with placebo (N=1250), discontinuation of amlodipine due to adverse reactions was required in about 1.5% of amlodipine-treated patients and about 1% of placebo-treated patients. The most common side effects were edema, dizziness, flushing, and palpitations.

The following events occurred in <1% but >0.1% of patients in controlled clinical trials or under conditions of open trials or marketing experience where a causal relationship is uncertain; they are listed to alert the physician to a possible relationship:

Cardiovascular: arrhythmia (including ventricular tachycardia and atrial fibrillation), bradycardia, chest pain, peripheral ischemia, syncope, tachycardia, vasculitis.

Central and Peripheral Nervous System: hypoesthesia, neuropathy peripheral, paresthesia, tremor, vertigo.

Gastrointestinal: anorexia, constipation, dysphagia, diarrhea, flatulence, pancreatitis, vomiting, gingival hyperplasia.

General: allergic reaction, asthenia, ¹ back pain, hot flushes, malaise, pain, rigors, weight gain, weight decrease.

Musculoskeletal System: arthralgia, arthrosis, muscle cramps, ¹ myalgia.

Psychiatric: sexual dysfunction (male¹ and female), insomnia, nervousness, depression, abnormal dreams, anxiety, depersonalization.

Respiratory System: dyspnea, ¹ epistaxis.

Skin and Appendages: angioedema, erythema multiforme, pruritus, ¹ rash, ¹ rash erythematous, rash maculopapular.

Special Senses: abnormal vision, conjunctivitis, diplopia, eye pain, tinnitus.

Urinary System: micturition frequency, micturition disorder, nocturia.

Autonomic Nervous System: dry mouth, sweating increased.

Metabolic and Nutritional: hyperglycemia, thirst.

Hematopoietic: leukopenia, purpura, thrombocytopenia.

¹ These events occurred in less than 1% in placebo-controlled trials, but the incidence of these side effects was between 1% and 2% in all multiple dose studies.

Clinical Laboratory Findings

Perindopril

Hematology

Small decreases in hemoglobin and hematocrit occur frequently in hypertensive patients treated with perindopril, but are rarely of clinical importance. In controlled clinical trials, no patient was discontinued from therapy due to the development of anemia. Leukopenia (including neutropenia) was observed in 0.1% of patients in U.S. clinical trials.

Liver Function Tests

Elevations in alanine transaminase (ALT; 1.6% perindopril erbumine vs. 0.9% placebo) and aspartate transaminase (AST; 0.5% perindopril erbumine vs. 0.4% placebo) have been observed in placebo-controlled clinical trials. The elevations were generally mild and transient and resolved after discontinuation of therapy.

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of the individual components of PRESTALIA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Perindopril

Voluntary reports of adverse events in patients taking perindopril that have been received since market introduction and are of unknown causal relationship to perindopril include: cardiac arrest, eosinophilic pneumonitis, neutropenia/agranulocytosis, pancytopenia, anemia (including hemolytic and aplastic), thrombocytopenia, acute renal failure, nephritis, hepatic failure, jaundice (hepatocellular or cholestatic), symptomatic hyponatremia, bullous pemphigoid, pemphigus, acute pancreatitis, falls, psoriasis, exfoliative dermatitis, and a syndrome that may include: arthralgia/arthritis, vasculitis, serositis, myalgia, fever, rash or other dermatologic manifestations, a positive antinuclear antibody (ANA), leukocytosis, eosinophilia, or an elevated erythrocyte sedimentation rate (ESR).

Amlodipine

The following postmarketing event has been reported infrequently where a causal relationship is uncertain: palpitations, gynecomastia, jaundice and hepatic enzyme elevations (mostly consistent with cholestasis or hepatitis), some requiring hospitalization.
