摘要:
The present invention describes a novel method for the purification of dexloxiglumide by crystallization from isopropyl ether which permits the production, in a reproducible manner, of a product with morphological and particle-size characteristics such as to favour its use in the preparation of oral pharmaceutical forms on an industrial scale.

New Orginal derivates of D,L-glutamic acid and D,L-aspartic acid are described having the formula: ##STR1## where n is 1 or 2, R.sub.1 is a mono- or di-substituted phenyl group substituted with halogens such as chlorine and fluorine or with a methyl group in the 3 and 4 positions and in which R.sub.2 consists of a linear or branched alkyl group with 4 to 7 carbon atoms (preferably a pentyl group) and R.sub.3 is an alkyl group having 3 to 6 carbon atoms overall and containing an oxygen atom in the form of an either linkage, such as for example the groups 2-ethoxyethyl, 3-methoxypropyl, 3-ethoxypropyl etc. or in the form of a hydroxyl group such as for example 3-hydroxypropyl etc.The compounds have antagonistic activity towards bio-active polypeptides and are usable particularly in the treatment of illnesses of the digestive tract, of the central nervous system and anorexia and of all those affections (for example tumours) in which exogenic or endogenic bio-active polypeptides are involved.

The invention describes compounds represented by the general formula (I) given below: in which: n is an integer between 1 and 4; R1 and R2 are chosen independently from hydrogen and a methyl group; R3 is chosen independently from a linear, branched or cyclic alkyl group containing from 1 to 3 carbon atoms (R3a) and a simple amino group (R3b) or an amino group substituted with a nitro group (R3c) The compounds are useful for treating central nervous system diseases or peripheral neuropathies.
摘要:
The invention is represented by a transdermal medicated patch for the extended release of 17.beta.-estradiol to the skin. The transdermal patch is formed by an outer covering, a matrix containing from 1% to 5% (w/w) 17.beta.-estradiol, and a protective liner which is removed before use. The matrix is formed of pressure-sensitive adhesive acrylic copolymers, in which the active ingredient is dissolved or dispersed. The acrylic copolymers are obtained by radical copolymerization of 2-ethylhexyl acrylate, methyl acrylate, acrylic acid, vinyl acetate, hydroxyethyl acrylate or a mixture thereof. Optionally quantities of less than 0.5% (w/w) of other substances may be added.

摘要:
Described is a new crystalline Form A of Andolast disodium salt, triclinic, displaying a thermal event at 98-112° C. and melting with decomposition at about 400° C. (DSC). Andolast disodium Form A is a not hygroscopic solid, surprisingly stable to several humidity conditions in a temperature range acceptable for ordinary storage conditions. In addition its stability allows both chemical manufacturing and pharmaceutical manufacturing process consistency and reproducibility under conditions more viable and less expensive when compared to those used for highly hygroscopic solids.
摘要:
Compounds which may be represented by the general formula (I) shown below and in which: R1 is a group independently selected from among: CHO, —COOH, —CH2OH R2 is hydrogen or a linear or branched C1-C6 alkyl group R3 is hydrogen or a halogen group selected from among Cl and Br R4 is a linear or branched C3-C5 alkyl group and the pharmaceutically acceptable salts thereof such as the sodium or potassium salt. The compounds exhibit potent and selective All antagonist activity and are useful for the treatment of any disorders in which elevated synthesis of All or overexpression of the AT1 receptor may play a primary pathological role, as in the case of arterial hypertension, congestive cardiac insufficiency, platelet aggregation and disorders associated therewith such as for example myocardial and cerebral infarction, renal ischaemia, venous and arterial thrombosis, peripheral vasculopathy, pulmonary hypertension, diabetes mellitus, diabetic neuropathy, glaucoma and diabetic retinopathy.
