    摘要： A multi-purpose pharmaceutical tablet which can either be readily swallowed or dissolved in water to give a dispersion, comprising a tetracycline, microcrystalline cellulose or microfine cellulose, low substituted hydroxypropylcellulose and a thickening agent, preferably hydroxypropyl methylcellulose, and optionally other conventional adjuvants. The tablet may be easily swallowed as such, and when immersed in water, it affords a very fine dispersion within 30-60 seconds. The tablet may be prepared by direct compression, or by a wet granulation process in which a granulate is used which contains tetracycline and any substantial amount of a wet binding substance.

    摘要： An improved process for the preparation in high yields of a compound of the formula ##STR1## wherein R is an optionally substituted phenyl group, Y is selected from the group consisting of Me and a hydrocarbon, Me is a metal cation and E is selected from the group consisting of hydrogen and a metal cation comprising reacting a compound of the formula ##STR2## wherein Q is selected from the group consisting of hydrogen and a silyl protecting group, Rz is an optionally substituted phenyl with the proviso that any hydroxy group present on the phenyl are replaced by --OQz, wherein Qz is a silyl protecting group and Ez is a carboxyl protecting group, with a compound of the formula ##STR3## wherein Z is a halogen and X is selected from the group consisting of OY and Z at low temperatures under anhydrous conditions and carefully hydrolyzing the resulting product either with just enough water to remove protecting groups and hydrolyze the Z groups to hydroxy groups and, still under anhydrous conditions, reacting the compound obtained with an organic metal salt carrying a metal cation Me or, in the case wherein the organic solvent is water-insoluble, with an excess of water, followed by washing the mixture with water acidified to a pH of 0 to 3, extracting the organic phase with neutral water and forming a salt with a hydroxide or a salt carrying a salt-forming cation Me.
