Single crystal structure, solid state characterization and dissolution rate of terbinafine hydrochloride

► Terbinafine hydrochloride (TH) was characterized through solid state techniques. ► TH single crystal structure was elucidated by X-ray single crystal diffraction. ► A new crystalline habit of TH was obtained and characterized as needle-like. ► Higher values of intrinsic dissolution rate were observed for TH raw material.
