发明名称 Highly loaded amorphous efavirenz composition and process for preparing the same
摘要 A stable and high loading ternary solid dispersion composition comprising (a) about 50% wt. to about 90% wt. of amorphous Efavirenz; (b) about 10% wt. to about 50% wt. of polyvinyl pyrrolidone (PVP), a first polymer; (c) about 1% wt. to about 30% wt. of a water-soluble second polymer; and (d) optionally about 0.1% wt. to about 50% wt. of at least one pharmaceutically acceptable excipient. Also discloses a high loading ternary composition comprising (a) a solid dispersion composition comprising (i) about 50% wt. to about 90% wt. of amorphous Efavirenz; (ii) about 10% wt. to about 50% wt. of polyvinyl pyrrolidone, a first polymer; (b) about 1% wt. to about 30% wt. of a water-soluble second polymer blended with solid dispersion of composition of (a); and (c) optionally about 0.1% wt. to about 50% wt. of at least one pharmaceutically acceptable excipient. Additionally discloses a method for preparing solid dosage forms comprising (i) amorphous Efavirenz and (ii) polyvinyl pyrrolidone (PVP), a first polymer; (iii) a water-soluble second polymer; and (iv) optionally, at least one pharmaceutical excipients.
