The invention, which belongs to the medicine field, relates to development for a tanshinol-naringenin composite pellet. Tanshinol being a water-soluble component of the root of red-rooted salvia being Chinese medicine is effective in treating angina pectoris. At present, most of tanshinol preparations being available in the market are immediate-release dosage forms that can not satisfy the demand of long-term therapy for angina pectoris; the bioavailability, being lower than 10%, of the preparation is low and the metabolism is fast, wherein t1 / 2 is equal to 0.5h approximately; and the pure sustained-release pellet can not keep enough blood concentration for long time and thus is not effective in treating angina pectoris. Besides, naringenin is capable of inhibiting activity of P450enzymeCYP3A4; and after taking of the naringenin with tanshinol, the metabolic process of the tanshinol in vivo can be inhibited, so that the bioavailability of tanshinol is enhanced and the plasma clearance is reduced. Therefore, according to development provided by the invention, tanshinol and naringenin are prepared into a composite pellet. In addition, enterohepatic circulation exists during oral naringenin taking and thus a long-acting effect can be realized by an immediate-release dosage form, so that the naringenin is prepared into an immediate-release pellet and the tanshinol is prepared into a sustained-release pellet.
