Manufacturing, pharmaceutical antibiotics

Methyl acetoacetate (MAA) and ethyl acetoacetate (EAA) are the most widely used esters they are found ia the pharmaceutical, agricultural, and allied industries. Both esters are used extensively as amine protecting agents ia the manufacture of antibiotics and synthetic sweeteners (Dane Salts) (147). Principal outiets for MAA are the manufacture of the organophosphoms insecticide dia2inon [33341-5] (148,149) and the uracil herbicides bromacil [31440-9] and terbacil [5902-51-2] (150,151) (see Insect conztiol technology Herbicides). [Pg.481]

In pharmaceutical appHcations, the selectivity of sodium borohydride is ideally suited for conversion of high value iatermediates, such as steroids (qv), ia multistep syntheses. It is used ia the manufacture of a broad spectmm of products such as analgesics, antiarthritics, antibiotics (qv), prostaglandins (qv), and central nervous system suppressants. Typical examples of commercial aldehyde reductions are found ia the manufacture of vitamin A (29) (see Vitamins) and dihydrostreptomycia (30). An acyl azide is reduced ia the synthesis of the antibiotic chloramphenicol (31) and a carbon—carbon double bond is reduced ia an iatermediate ia the manufacture of the analgesic Talwia (32). [Pg.304]

Pharmaceuticals. -Hydroxybenzaldehyde is often a convenient intermediate in the manufacture of pharmaceuticals (qv). For example, 2-(p-hydroxyphenyl)glycine can be prepared in a two-step synthesis starting with -hydroxybenzaldehyde (86). This amino acid is an important commercial intermediate in the preparation of the semisynthetic penicillin, amoxicillin (see ANTIBIOTICS, P-LACTAMs). Many cephalosporin-type antibiotics can be made by this route as well (87). The antiemetic trimethobenzamide [138-56-7] is convenientiy prepared from -hydroxybenzaldehyde (88) (see Gastrointestinal agents). [Pg.508]

Pharmaceutical. Ion-exchange resins are useful in both the production of pharmaceuticals (qv) and the oral adrninistration of medicine (32). Antibiotics (qv), such as streptomycin [57-92-17, neomycin [1404-04-2] (33), and cephalosporin C [61-24-5] (34), which are produced by fermentation, are recovered, concentrated, and purified by adsorption on ion-exchange resins, or polymeric adsorbents. Impurities are removed from other types of pharmaceutical products in a similar manner. Resins serve as catalysts in the manufacture of intermediate chemicals. [Pg.387]

AH steps of manufacture are monitored for antibiotic potency, purity, stabiUty, and bioavailabihty by quaUty control methods. In addition, each batch of bulk powder and each lot of finished pharmaceutical dosage form must be certified by the FDA. During all stages of manufacture the FDA requires compliance with specified standards. [Pg.180]

Pharmaceutical microbiology may be defined as that part of microbiology which has a special bearing on pharmacy in all its aspects. This will range fiom the manufacture and quality control of pharmaceutical products to an understanding of the mode of action of antibiotics. The full extent of microbiology on the pharmaceutical area may be judged fiom the chapter contents. [Pg.1]

It must be pointed out that GMP guides are not intended to cover health security aspects for the personnel engaged in manufacturing. They may be very important in the manufacture of certain bulk pharmaceutical chemicals or medicinal products, such as cytostatics, antibiotics, or other highly active, biological and radioactive products, but they are governed by other provisions of law. [Pg.515]

The current Good Manufacturing Practice (cGMP) regulations are guidelines that FDA requires a pharmaceutical manufacturer to meet. Compliance with the cGMPs is a prerequisite for the approval of NDAs, INDs, and antibiotic forms. General areas in which... [Pg.412]
