Abstract: The present invention relates to an improved process for the synthesis of Etelcalcetide and its analogs by solid phase synthesis of Fmoc protected amino acids in a sequential manner, followed by acetylation of terminal D-cys and cleavage of peptide from solid support. The crude heptapeptide thus obtained is reduced using Tris(2-carboxyethyl) phosphine hydrochloride, purified and oxidized with L-cysteine. The oxidized Etelcalcetide is purified and salt exchanged using a one-step reverse phase chromatography process. The purified Etelcalcetide hydrochloride is then precipitated using organic solvents, concentrated and lyophilized to purity of greater than 99.0%.

Abstract: This invention provides coated pellets comprising a) a pellet core which comprises venlafaxine hydrochloride; b) a first coating which comprises a lipophilic layer or a sparingly water-soluble layer, and c) a second coating which comprises a water-insoluble polymer or polymer mixture. In another aspect this invention provides compositions which comprises the coated pellets. In a further aspect, the invention provides a process for preparing the coated pellets which process avoids use of organic solvents at least for the second coating.

Abstract: The invention relates to an orally administrable pharmaceutical comprising an alginate matrix consisting of a water-soluble alginate salt and a complex salt of alginic acid, a macrolide, and an inorganic salt characterized in that the inorganic salt is capable of donating a proton and has a pKa value in water of 4.0 to 9.0.

Abstract: A pharmaceutical composition having improved solubility comprising a hydrophobic drug or pharmaceutically acceptable salt thereof and a compound having at least one carboxylic acid moiety, wherein the molar ratio of the compound having at least one carboxylic acid moiety to the hydrophobic drug or pharmaceutically acceptable salt thereof is from about 0.1:1 to about 25:1. The pharmaceutical composition exhibits rapid dissolution upon contact with physiological solvents, such as water, saliva or gastrointestinal fluids.
