Perindopril arginine is a stable L-arginine salt of perindopril. Perindopril, a pro-drug, is hydrolyzed to perindoprilat, which inhibits ACE in humans and in animals. It is indicated for the treatment of hypertension, heart failure and coronary artery disease. Perindopril arginine may be used in monotherapy or in combination with other classes of antihypertensive therapy.

Perindoprilat is a metabolite of perindopril. Perindopril is a long-acting angiotensin converting enzyme (ACE) inhibitor and it is used to treat high blood pressure, heart failure or stable coronary artery disease. Perindopril is designed to allow oral administration as perindoprilat is poorly absorbed from the gastrointestinal tract.

L-arginine is a nonessential amino acid that may play an important role in the treatment of cardiovascular disease due to its antiatherogenic, anti-ischemic, antiplatelet, and antithrombotic properties. It has been promoted as a growth stimulant and as a treatment for erectile dysfunction in men. L-arginine is a nonessential amino acid that may play an important role in the treatment of heart disease due to its block arterial plaque buildup, blood clots, platelet clumping, and to increase blood flow through the coronary artery. L-arginine is commonly sold as a health supplement claiming to improve vascular health and treat erectile dysfunction in men. L-arginine, which is promoted as a human growth stimulant, has also been used in bodybuilding. In the 1800s, it was first isolated from animal horn.

Erbumine (tert-butylamine) is a colorless liquid with an ammonia-like odor. It is used in the preparation of insecticides, pharmaceuticals, oil additives, and rubber accelerators. It neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides.

(±)-3A,7A-di-epi-Perindopril is a mixture of two isomers (S, RR, SS) and (R, SS, RR) each of which is an isomer of the antihypertensive drug perindopril. The first of which has the same activity as the compound while the second one is almost inactive.

(1''R,3AR)-1'',3A-di-epi-Perindopril is an epimer (S, RS, SR) of the drug perindopril which is commonly used to treat high blood pressure, hypertension, heart failure, or stable coronary artery disease. This form of the drug is much less active than the parent compound, perindopril.

(2R,2'R)-2,2'-di-epi-Perindopril is an epimer (R, SS, RS,) of the drug perindopril which is commonly used to treat high blood pressure, hypertension, heart failure, or stable coronary artery disease. This form of the drug is much less active.

(2R,7AR)-2,7A-di-epi-Perindopril is an epimer (R, SR, SS) of the drug perindopril which is commonly used to treat high blood pressure, hypertension, heart failure, or stable coronary artery disease. This form of the drug is much less active.

(±)-2,3A-di-epi-Perindopril is a mixture of two isomers (S, SR, RR) and (R, RS, SS) which are both inactive epimers of the antihypertensive drug perindopril, although the (R, RS, SS) isomer possesses better activity.

(±)-2',7A-DI-EPI-PERINDOPRIL is a mixture of two isomers (S, SR, RS) and (R, RS, SR) which are both almost inactive epimers in of the antihypertensive drug perindopril.
