A semisolid aqueous pharmaceutical composition containing tapentadol or a physiologically acceptable salt thereof.

The present invention comprises an all-natural composition of matter and methods of delivering nutrients, medicines, pain relievers, antioxidants, antidotes, antibiotics and various active ingredients and supplements directly to the affected area of the body. The all-natural carrier composition consists essentially of the combination of a natural oil, water, salt(s), natural emulsifier, natural sugar(s), plant extracts, natural acid(s), starch and natural flavor(s). The active substances that are mixed with the all-natural carrier composition, include, but are not limited to, drugs, vitamins, minerals, antibiotics anti-fungal agents, antioxidants, diuretics, allergy medicines, anti-inflammatory agents, muscle relaxers, pain reducers, diabetic drugs, neuropathy drugs, chemotherapy agents, arthritis drugs, lotions for eczema, shingles, psoriasis, skin rash; herbal medicines, erectile dysfunction drugs, hormones, cholesterol drugs, essential fatty acids, and the like. The all-natural carrier composition facilitates the penetration of active substances into the dermal layer of the skin.

Herein is reported a polypeptide comprising a first polypeptide and a second polypeptide each comprising in N-terminal to C-terminal direction at least a portion of an immunoglobulin hinge region, which comprises one or more cysteine residues, an immunoglobulin CH2-domain and an immunoglobulin CH3-domain, wherein the first, the second, or the first and the second polypeptide comprise the mutation Y436A (numbering according to the EU index).

The invention relates to the field of drug carrier preparation, in particular to a gastric targeted drug carrier and a preparation method thereof. The gastric targeted drug carrier is prepared from the following raw materials: drug-containing emulsion and a crosslinking agent, wherein the drug-containing emulsion contains chitosan, chitosan quaternary ammonium salt and sodium glycerophosphate; and the crosslinking agent is used for crosslinking the emulsion into microspheres. The preparation method comprises the following steps: 1) preparing the drug-containing emulsion: with a aqueous solution of chitosan, chitosan quaternary ammonium salt and sodium glycerophosphate as an aqueous phase W, preparing the drug-containing emulsion with the aqueous phase, drugs and an oil phase containing anemulsifying agent; and 2) heating and stirring the drug-containing emulsion prepared in the step 1), crosslinking the chitosan quaternary ammonium salt and sodium glycerophosphate contained in the drug-containing emulsion to obtain gel microsphere suspension, heating the suspension and adding the crosslinking agent to carry out secondary crosslinking to solidify the gel microspheres. The drug carrier has the advantages of uniform and controllable grain size, high embedding rate and good dispersibility and simultaneously meets the requirements of the gastric targeted drug delivery carrier.

The invention belongs to the field of pharmaceutical preparations, and in particular relates to a colonic positioning drug release pellet of camptothecin and a preparation method thereof. First of all, the present invention provides a camptothecin nanoemulsion / pellet with colon-positioned drug release. The preparation of camptothecin into a nanoemulsion can improve the solubility of camptothecin, and further preparation into a concentrated nanoemulsion / pellet can be used to improve the solubility of camptothecin. The drug-loaded amount is doubled, and the drug-loaded nanoemulsion can be positioned and released in the colon. Camptothecin can be directly absorbed in the form of nanoemulsion, which avoids the problem of the opening of its lactone ring, and increases the solubility of camptothecin. It can smoothly cross the aqueous barrier on the surface of the colon and be taken up by colon cancer tissue, which enhances the curative effect and reduces the toxicity, and has great application value.

The invention concerns the use of an antimicrobial composition comprising metallic silver and metallic ruthenium as well as at least one vitamin or at least one vitamin derivative for the topical treatment or prevention of skin, skin adnexa or mucosa diseases which are caused by infection with at least one microorganism.
