The selected conditions were used to design the densitometric method for the content determination of the above mentioned compounds in substances and medicines. The statistical data obtained for the designed method indicate ade- quate accuracy and precision. Keywords: lisinopril, quinapril, ramipril, spirapril, moexipril, trandolapril, benazepril, cilazapril, fosinopril, captopril, enalapril, imidapril, zofenopril, perindopril, antihypertonics, densitometric metod Arterial hypertension is one of the most com- the body they are subjected to hydrolysis into acids, mon cardiovascular disorders.
