Study of drug–excipient
interactions is a crucial step in preformulation stage of drug development to
achieve consistent chemical, physical, bioavailability, manufacturability and
stability of the dosage form. In pre-formulation
studies, it is important to use thermoanalytical and spectroscopic methods.
These are important systems for achieving a suitable formulation. Sildenafil is a well-tolerated and highly
effective treatment for erectile dysfunction. erectile dysfunction was
revolutionized with the development of a
selective inhibitor of cyclic guanosine monophosphate-specific
phosphodiesterase type 5. , Fourier Transform Infrared Spectroscopy, and X-ray Powder Diffraction systems were used in the investigation and to
determine the possible interactions between sildenafil and some excipients like
butylated hydroxyanisole, cellulose, sodium carboxymethyl cellulose, ascorbic acid, and citric acid. Binary mixtures of drug:excipient=1:1
(mass/mass) have been analyzed. According to the results, there is
incompatibility with butylated hydroxyanisole, ascorbic
acid, and citric acid.
