Kadar kaptopril yang tersisa sebagai fungsi waktu ditentukan dengan kromatografi cair kinerja tinggi. hasil penelitian yang diperoleh menunjukkan bahwa penambahan natrium metabisulfit, natrium askorbat, atau asam askorbat, sebagai antioksidan tidak berperan nyata dalam peningkatan stabilitas; sedangkan penambahan natrium tiosulfat atau hidrokuinon menurunkan stabilitas kaptopril.</mods:abstract><mods:classification authority="lcc">QV 150-160 Cardiovascular Agents.
