This invention discloses the application and method of a STAT1-targeting inhibitor in the treatment of immune thrombocytopenic purpura (ITP). It employs ivermectin, a STAT1 nuclear translocation inhibitor, and fludarabine, a STAT1 activation inhibitor. By injecting either the activation inhibitor or the nuclear translocation inhibitor, the platelet count in a mouse model of ITP is increased. Fludarabine, a fluorinated nucleotide analog of vidarabine, is non-radioactive and a small-molecule phosphorylation inhibitor. Ivermectin is a small-molecule inhibitor of nuclear translocation mediated by α / β1 introgression protein. Both have high bioavailability and are widely used to treat various hematological diseases with good safety profiles. Their application in treating ITP is safe, effective, and shows high compliance.

The application relates to a preparation method of ivermectin, which comprises the following steps: carrying out a hydrogenation reaction on abamectin and hydrogen under the action of catalyst A and catalyst B, and using anhydrous ethanol and toluene as reaction solvents to generate ivermectin; wherein the catalyst A is a copper-cobalt complex catalyst, and the catalyst B is phosphotungstic acid. The catalyst does not contain noble metal, the catalyst cost is reduced, and the separation and purification process is simplified.

This invention relates to the field of veterinary drugs, specifically to an albendazole-ivermectin premix and its preparation method. The premix, by weight percentage (100%), comprises the following raw materials: albendazole 9.5-10.5%, ivermectin microcapsules 0.19-0.21%, sodium chloride 12-24%, and the balance being modified starch. The albendazole-ivermectin premix prepared by this invention can be uniformly mixed through a simple process, exhibiting high homogeneity.

This disclosure relates to methods for treating diseases and / or conditions (including long COVID) associated with Covid-19 infection, the methods comprising administering a COX-2 inhibitor, an antiviral compound, and one or more additional active ingredients, such as a combination of nematvir and ritonavir, monorapvir, a BCG vaccine, or ivermectin.

The application discloses albendazole and ivermectin premix and a preparation method thereof. The premix comprises albendazole 8-15%, ivermectin 0.2-0.4%, double-layer inclusion carrier 20-30% and various auxiliary materials in percentage by mass. The application adopts the double-layer inclusion carrier formed by inner layer hydroxypropyl-beta-cyclodextrin and outer layer hydroxypropyl methylcellulose phthalate and povidone K30 to form an enteric barrier. The preparation method comprises the steps of inner layer inclusion, outer layer dispersion, mixing and granulation. The relative bioavailability of the premix reaches 203%-221%, the pig ascarid drive rate is 98.7%-99.5%, the scabies mite negative conversion rate is 98%-100%, the diarrhea incidence is only 2%-3%, the premix is safe for pregnant sow groups, and no adverse reactions such as abortion, premature birth and loss of appetite occur in all test pigs during the test period. The problems of uneven mixing, low bioavailability and large side effects of traditional preparations are solved, and the premix is suitable for livestock and poultry parasite prevention and treatment.

The present invention relates to a composition comprising ivermectin or pharmaceutically acceptable salt thereof prepared by wet granulation.

The present invention contemplates the use of inhaled ivermectin for use in various viruses and parasitic infections (treatment and / or prophylaxis) that are present or manifest in the lungs or respiratory tract. Exemplary dosing, formulations, devices, and processing techniques are also disclosed herein.

The application belongs to the field of veterinary drugs and discloses an ivermectin enteric granule, which comprises PEG6000, enteric material HPMCP-hp50 and ivermectin, the particle size of the ivermectin enteric granule is 20-50 mesh, the amount of the PEG6000 is equivalent to 54-84% of the total weight of the ivermectin enteric granule, and the amount of the enteric material HPMCP-hp50 is equivalent to 10-15% of the total weight of the ivermectin enteric granule, the granule takes PEG6000 as a skeleton, takes HPMCP-hp50 as an enteric material, and loads ivermectin in the skeleton, through the above structure, the enteric granule can be ensured to be insoluble in gastric juice, to be rapidly released and absorbed in the front section of the intestinal tract, through in-vitro release experiments, it can be found that the release speed can be kept at 67% at least in 1h, through in-vivo pharmacokinetic experiments on the best case piglets, it is found that the Cmax of the piglets orally administered with the ivermectin enteric granule is significantly improved compared with the ivermectin tablet, the average relative bioavailability is increased by about 78%, the absolute bioavailability is increased from 37.4% to 66.5%, and the application further provides a preparation method and application of the ivermectin enteric granule.
