Sterile liquid dosage forms

Liquid dosage forms. The liquid products are prepared by dissolving the ingredients in the appropriate solvent systems. Dyes, flavors, sweeteners, and antimicrobial preservatives are added to mask unpleasant taste or appearance, and to prevent mold and bacterial growth. The final products are stored in large tanks before final packaging. If the liquid is used for injection or ophthalmic use, the liquid must be sterilized. Solutions for external or oral use do not require sterilization but generally contain antimicrobial preservatives [16, 17]. 

Because it is bitter, this antibiotic is administered orally cither in capsules or as the palmitatc e.ster. Chloramphenicol palmitate is insoluble in water and may be suspended in aqueous vehicles for liquid dosage forms. The ester forms by reaction with the hydroxyl group on C-3. In the alimentary tract, it is hydrolyzed slowly to the active antibiotic. Chloramphenicol is administered parenterally as an aqueous suspensiuti of very fine cry.stals or as a solution of the sodium salt of the succinate ester of chloramphenicol. Sterile chloramphenicol sodium succinate has been used to prepare aqueous. solutions for intravenous injection.

The plant is designed to produce oral solid dosage forms as well as liquid dosage forms, ointments, creams, suppositories, and sterile injectable products. 

Product quality reviews may be grouped by product type, e.g. solid dosage forms, liquid dosage forms, sterile products, etc. where scientifically justified. This is an appropriate approach for a quality review of non-standardised pharmacy preparations, see also Sect. 34.14.3. 

Dosage form Rituxan is a sterile, preservative-free liquid concentrate for injection. It is supplied at a concentration of lOmg/ml in either 100 mg (10 ml) or 500 mg (50 ml) single-use vials. 

The book is divided into six volumes based strictly on the type of formulation science involved in the development of these dosage forms sterile products, compressed solids, uncompressed solids, liquid products, semisolid products, and over-the-counter (OTC) products. Although they may easily fall into one of the other five categories, OTC products are considered separately to comply with the industry norms of separate research divisions for OTC...

The dry powders that are reconstituted in their marketed container need not be sterile however, the possibility of an interaction between the packaging components and the reconstituting fluid can t be discarded. Although the contact time will be relatively short when compared to the component/dosage form contact time for liquid-based oral dosage forms, it should still be taken into consideration when the compatibility and safety of the container closure system are being evaluated. 

Injectable dosage forms are sterile and represent one of the highest risk drug products. Injectable drug products may be liquids in the form of solutions, emulsions, and suspensions or dry solids that are to be combined with an appropriate vehicle to yield a solution or suspension. 

AH injectable solutions are tested for sterility and absence of pyrogens. Various chromatographic techniques, such as high performance liquid chromatography (HPLC), and other analytical techniques are used in the quality control laboratory to determine the purity and the amount of active drug present in the different dosage forms.

The inclusion of a routine Microbial Limit Test in a marketed product stability protocol will depend on the pharmaceutical dosage form. Typically, the test would be used for only non-sterile products, particularly oral liquids, nasal sprays and topical liquids, lotions and creams that have a sufficient water activity to support the growth of microorganisms. In contrast, tablets, powder and liquid-filled capsules, topical ointments, vaginal and rectal suppositories,... 

The average number of recalls per annum for microbial contamination of non-sterile pharmaceutical and OTC drug products is six (Table 4). The emphasis on waterborne Gram-negative bacteria of the species Bulkholderia (Pseudomonas) cepacia (nine recalls), P. putida (three recalls), P. aeruginosa (three recalls). Pseudomonas spp. (two recalls), and Ralstonia (P.) pickettii (one recall) is notable and reflects the concern for bacteria capable of growth in liquid oral dosage forms that overwhelm the preservative system. 

Fig. 3 shows a pilot plant layout with restricted personnel access. This design would support the development and clinical manufacture of solid dosage forms, liquids, semisolids, aerosols, and sterile products. Multipurpose rooms are incorporated in each area to maximize the use of portable equipment, and scale factors similar to those shown in Table 1 are employed. Isolation suites are indicated in the manufacturing area their purpose and design are discussed in more detail later. The sterile area is isolated from the main corridor by the interior corridor design. At the far left, the main corridor provides access for future facility expansion, if necessary. 

The type of dosage form is primarily related to the physical state, e.g. solid, liquid or gas, and whether it is sterile, non-sterile, unit dose or multi-dose.
