摘要:
A free-flowing, amorphous paroxetine hydrochloride-ethanol composition suitable as a therapeutic agent for premature ejaculation can be prepared by dissolving paroxetine free base in a hydrochloric acid-ethanol solution followed by drying. In a preferred embodiment, the amount of ethanol present in the amorphous product is in the range of 1 to 4 weight percent based on paroxetine hydrochloride. The amorphous product is stable and substantially non-hygroscopic.
摘要:
Ethereally substituted monosaccharides are prepared from certain selectively derivatized monosaccharides. In practicing the method:1. a monosaccharide derivative having the general formula A.sub.1 -O-H, wherein O is oxygen, H is hydrogen and A.sub.1 is the residue of a monosaccharide selected from the group consisting of pentoses, hexoses and heptoses which has been derivatized with at least one substance selected from the group consisting of (1-a) at least one aliphatic alcohol containing 1-18 carbon atoms to produce an hydrolyzable acetal group at the site of at least one available hydroxyl residue, (1-b) at least one aldehyde containing 1-18 carbon atoms to produce at least one hydrolyzable acetal group at the site of at least one available hydroxyl residue, (1-c) at least one ketone containing 1-18 carbon atoms to produce at least one hydrolyzable ketal group at the site of at least one available hydroxyl residue, and (1-d) at least one organic acid residue containing 1-18 carbon atoms to produce an hydrolyzable ester group at the site of at least one available hydroxyl residue; is reacted with2. an organic halide having the general formula Y - X, wherein X is selected from the group consisting of chlorine, bromine and iodine and Y is selected from the group consisting of (2-a) cyclic monovalent nitrogen containing organic radicals and residua, and (2-b) monovalent organic radicals and residue having the general formula -R.sub.1 B wherein B is selected from the group consisting of ##STR1## --O--R.sub.4 and --S--R.sub.4, R.sub.1 is a divalent organic radical having a linear carbon chain length of about 1-7 carbon atoms, R.sub.2 and R.sub.3 are selected from the group consisting of --H,--OH, --SH, halogen and monovalent organic radicals and residua having a linear carbon chain length of about 1-7 carbon atoms, R.sub.4 is selected from the group consisting of --H and monovalent organic radicals and residua having a linear carbon chain length of about 1-7 carbon atoms, N is nitrogen, O is oxygen, S is sulfur and H is hydrogen;To produce an ethereally substituted monosaccharide derivative having the general formula A-O-Y wherein A, Y and O are as above defined. The monosaccharide derivative (1) and the organic halide (2) are reacted at an elevated reaction temperature while dissolved in a substantially anhydrous organic solvent in the presence of a solid substantially anhydrous strong inorganic base of a metal selected from the group consisting of the alkali metals and the alkaline earth metals. The resultant ethereally substituted monosaccharides may be partially or fully hydrolyzed in an aqueous acidic medium. In one preferred variant, 1,2:5,6-di-O-isopropylidene 3-O-3'-(N',N'-dimethylamino-n-propyl)-D-glucofuranose is prepared and, when desired, thereafter partially or fully hydrolyzed to produce 1,2-O-isopropylidene-3-O-3'-(N',N'-dimethylamino-n-propyl)-D-glucofuranose or 3-O-3'-(N'-N'-dimethylamino-n-propyl-D-glucose in the free amine and/or salt forms. The method is capable of preparing the ethereally substituted monosaccharides in high yield and purity with a minimum of side products. The resultant compounds exhibit striking antiviral activity and/or have other therapeutically valuable properties and are useful in the treatment of warm-blooded animals.
摘要:
A stable amorphous paroxetine hydrochloride composition suitable as a therapeutic agent is prepared employing an aqueous solvent medium containing an acidulant and polyvinylpyrrolidone and drying the resulting solid dispersion. The preferred compositions include amorphous paroxetine hydrochloride, polyvinylpyrrolidone and citric acid.
摘要:
Symptoms of Parkinson's disease and psychogenic male erectile dysfunction (MED) can be ameliorated through the use of apomorphine. The adverse side effects of apomorphine administration, such as nausea, vomiting, yawning, and cardiovascular effects, can be significantly reduced by a dose escalating method of acclimatization. An initial dose of apomorphine is administered to the patient, and subsequently increased over a period of time until a final apomorphine dose in excess of a desired therapeutic dose has been received by the patient. Thereafter a therapeutic dose of apomorphine, less than the final apomorphine dose, is administered to the patient with attendant reduced side effects.
摘要:
Derivatives of -.alpha.,D-glucofuranose .alpha.,D-allanfuranose and intermediates for preparing these derivatives are described. These derivatives are useful for treating animals and mammals with inflammatory and/or autoimmune disorders such as psoriasis, atopic dermatitus, rheumatoid arthritis, osterarthritis, scleroderma and systemic lupus erythematosus.
摘要:
A free-flowing, amorphous paroxetine hydrochloride composition suitable as a therapeutic agent for premature ejaculation can be prepared by dissolving paroxetine free base in a hydrochloric acid-ethanol solution followed by drying. The present compositions comprise amorphous paroxetine hydrochloride and at least one hydroxyl-bearing compound. In one preferred embodiment, the hydroxyl-bearing compound is ethanol and the amount of ethanol present in the amorphous product is in the range of 1 to 4 weight percent based on paroxetine hydrochloride. The amorphous product is stable and substantially non-hygroscopic.
摘要:
Impotence can be ameliorated without substantial undesirable side effects by nasal administration of apomorphine, optionally with an antiemetic agent present in an amount sufficient to substantially reduce nausea symptoms that may be associated with the use of apomorphine.
摘要:
Psychogenic impotence can be ameliorated without substantial undesirable side effects by administration of apomorphine and an antiemetic agent in an amount sufficient to substantially reduce nausea symptoms associated with the use of apomorphine.
摘要:
Sexual dysfunction in human females can be ameliorated, without substantial undesirable side effects, by sublingual administration of apomorphine dosage forms. Administration of apomorphine increases nerve stimulated clitoral intracavernosal blood flow and vaginal wall blood flow for enhanced clitoral erection and vaginal engorgement in a female. A plasma concentration of apomorphine of no more than about 5.5 nanograms per milliliter is preferably maintained.
