There are some requirements for the granulating liquid, one of them is that the granulating liquid should not dissolve the active substance. Water, an aqueous solution of ethanol, acetone and methylene chloride can be used as a granulating liquid. A wide range of substances are used as binding agents for wet granulation in modern pharmaceutical production, for example: starch (5-15% g/g), starch derivatives, cellulose derivatives that improve the plasticity of granules, as well as gelatin (1-3% g/ g) and PVP (3-10% g/ g). The most common and effective binder for wet granulation in the modern pharmaceutical industry is a synthetic polymer such as Collidone (PVP), various brands of which (Collidone 25, 30 and 90F) are widely represented on the market.

General recommendations for the selection of pharmaceutical equipment. The right choice of equipment is one of the most important issues of the organization of modern industrial production. Reliable, optimally selected and well-proven equipment largely determines the quality of the manufactured product, its competitiveness, and is also a guarantee of the successful development of production as a whole. The selection of equipment (for the pre-modern production of pharmaceutical products is carried out on the basis of many criteria. First of all, the equipment must be designed and optimally suited for the technological processes of production of a particular pharmaceutical product. Usually, preference is given to production machines and installations that allow several technological operations to be carried out at once, since their structural elements and operating...

There are empty capsules in the capsule bin. The capsules move down into two magazines, are aligned by the sorting unit and lowered into the corresponding cells. At the first stage of this operation, the first (internal) one is loaded a row of capsules, on the second one — the second (external) one is loaded a number of capsules. After the capsule magazine there is a narrow calibration hole. Only geometrically correct capsules can pass through this hole. In case of irregular shaped capsules that are unable to pass through the calibration hole, the cells are blocked, recognized by the scanner and excluded from the further filling process.

A band-Aid (Leucoplastrum), or a sticky elastic band-aid smeared (Emplastrum adhaesivum elasticum externum). It is used to hold bandages, to bring the edges of wounds closer together, to stretch the limb in case of fracture, etc. It consists of the following components: 25.7 parts of natural rubber, 20.35 parts of rosin, 32 parts of zinc oxide, 9.9 parts of anhydrous lanolin, 11.3 parts of liquid paraffin and 0.75 parts of neozone D. The adhesive plaster production process includes several stages: the dissolution of natural rubber and rosin in gasoline, the preparation of an alloy of lanolin with liquid paraffin, mixing it with finely ground zinc oxide and the preparation of a paste of anti-oxidant rubber. The application of the finished mass of adhesive plaster to...

As noted above, encapsulated dosage forms are becoming increasingly important due to their obvious advantages over other dosage forms. This section will consider the technology of production of solid gelatin capsules, which are most widely used in the modern pharmaceutical industry, as well as the equipment on which their manufacture is carried out. Characteristics of the main and auxiliary substances included in the composition of solid gelatin capsules. To obtain capsule shells, film-forming high-molecular substances capable of forming elastic films characterized by a certain mechanical strength are used. Such materials include casein, zein, cellulose esters and esters, fats and wax-like substances, as well as some synthetic polymers (for example, a copolymer of methacrylamide and methacrylic acid, etc.). However, these substances have not found wide practical...

Pepper plaster (EmplastrumCapsici) is a homogeneous sticky mass of yellow-brown color with a peculiar smell, applied to a fabric and covered with a protective layer of cellophane. Currently, a wide range of patches of various sizes is available: 12x18 cm, 10x18 cm, 8x18 cm, 10x15 cm, 4x10 cm, 6x10 cm, etc.The pepper patch has the following composition: 8% thick extract of capsicum, 0.6% thick extract of belladonna, 0.6% tincture of arnica, 22% natural rubber, 21% pine rosin, 18% anhydrous lanolin, 24% petroleum jelly oil and other components.

The calculated amount of purified water is poured into the container, which is heated to a temperature of + 65 ° C in a gelatin mass preparation apparatus, and a stirrer is turned on. Then glycerin is poured with nipagin and gelatin is filled in. The gelatin mass is mixed for 1.5 hours until the gelatin is completely dissolved, then, with the agitator turned off, it settles for 0.5—1.5 hours. After that, the gelatin mass is filtered through a sieve and its viscosity is measured using a viscometer. If the viscosity indicators do not correspond to the norm, the ratio of water and gelatin is recalculated. The filler solution is prepared according to the technological instructions. The prepared gelatin mass and filler in the required...

A film coating is a thin shell formed on the surface of a microsphere (pellets). Tablets or granules after drying of the film-forming substance solution applied to their surface. The thickness of the film coating layer is approximately from 5 to 50 microns. The droplets of the coating liquid are sprayed onto the initial particles. The supplied process air evaporates the liquid and dries the film layer on the surface of the particles. The small droplet size and low viscosity ensure uniform distribution of the film on the particle surface. An important point when applying the coating is a very uniform application of the coating material. The coatings must be dense, without mechanical damage and cracks. Film coating is an effective way of applying protective...

Modified release film coatings can be applied to pharmaceutical products to achieve modification, control the release of a medicinal substance. All coatings on the kinetics of drug release can be divided into the following four types: Coatings that provide periodic release of LV (intermittent release). This type includes coatings resistant to the effects of gastric juice — intestinal soluble coatings. Coatings that provide instant release of LV. Coatings that provide a steady (continuous) release of LV. Coatings that provide delayed (delayed) release of LV. Let's look at each type of coatings in more detail. Coatings that provide periodic release of the medicinal substance. This type of coating provides a prolonged effect of the dosage form, when injected into the body, LV is released in portions,...

With this type of coating, the medicinal substance from the tablets can be released instantly. These types of coatings include polymers developed by BASF: polyvinyl alcohol (PVA), Kollicoat IR white and Kollicoat Protect. PVS-based films are very elastic, but the coating process is possible only in a narrow range of varying technological parameters. This polymer is rapidly dispersed in water during the preparation of the dispersion for the film coating, forms shiny, non-sticky and very flexible films that do not crack during storage. The addition of a plasticizer is not required to create a coating. Kollicoat IR can be replaced by GPMC and other coatings with immediate release of LV in new tablet preparations. The use of Kollicoat IR increases the cost-effectiveness of the coating...
