Solution-tablets

Consequently, commercially available preparations of chlorpromazine and its hydrochloride salt should be protected from light. Chlorpromazine hydrochloride oral solutions, tablets, extended-release capsules and injections should be stored at a temperature less than 40°C, preferably between 15-30°C and in well-closed containers [2]. 

Oral. Taken by mouth—include liquids, emulsions, suspensions, dispersion solutions, tablets, capsules, powders, granules, lozenges, pastilles, and pills. 

The commercial valerian products consist of, or are derived from, the rhizome, roots, and stolons of Valeriana officinalis L. The crude herb is dried and may be used as is or to prepare an extract that can be used to make an oral solution, tablet, capsule, or tea. Active constituents of valerian include acetoxyvalerenic acid, 1-acevaltrate, baldrinal, didrovaltrate, hydroxyvalerenic acid, kessane derivatives, valeranone, valerenal, valerenic acid, and valtrate (Figure 65.1).

This section summarizes the field studies performed to compare the efficiencies of dechlorination chemicals under identical conditions to evaluate the chemical of choice for various dechlorination applications (18,19). The field tests were conducted at Tacoma Waters, WA, Portland Bureau of Water Works, OR, and East Bay Municipal Utility District (EBMUD), CA. Six dechlorination chemicals were used in solution, tablet, or powder form in these tests (Table 3). In the Tacoma and Portland studies, a 1 % solution of the dechlorination chemicals were introduced into water released from a hydrant. The field studies evaluated the rate of dechlorination, effect of overdosing, and concurrent water quality impacts when stoichiometric or twice the stoichiometric amounts of dechlorination agents were added. In the EBMUD dechlorination studies, bags, or dispensers containing tablets or powders of dechlorination chemicals were placed in the flow path of hydrant water. At all three sites, the water used for the test originated from surface water sources rather than from groundwater sources. Table 3 summarizes the chemicals, forms and dosing rates used in these studies. 

Trichlorfon was introduced in 1950, and has been used as an insecticide since 1952. It is available in the form of dust, granular, emulsifiable concentrate, soluble powdei injectable solution, tablets, and fly bait. Trichlorfon is a broad-spectrum insecticide that is particularly used against Diptera. It is used to control a variety of other insects in field, vegetable, and fruit crops, and forestry. In domestic animals, trichlorfon is used for the control of internal and external parasites.

The iodimetric method of assay is favoured for many official purposes and it can be applied, with very little sample preparation, to injections, tablets and solution-tablets. For ointments and similar preparations it is not directly applicable since high results may be obtained due to iodine absorption by the base. For preparations of this type Boymond has recommended iodimetric determination after mixture with benzene and extraction with water. 

Borax, Na2B4O7,10H2O, Mol. Wt. 38T4. Borax hydrolyses in aqueous solution to boric acid and sodium hydroxide and hence has an alkaline reaction. When borax is titrated with a strong acid to methyl orange or methyl red, the end-point is quite sharp and occurs when the acid is entirely in the free state, as boric acid is quite unaffected by these indicators. The B.P. method is by this titration. 1 ml 0 5N — 0 09536 g. It can then be titrated as described above under Boric Acid. The second titration should be double that of the first any disagreement would indicate excess of boric acid or alkali, and this fact is used for mixtures of borax and sodium bicarbonate such as Alkaline Nasal Solution-tablets, j5.P.C, and Compound Thymol Solution-tablets, B.P.C. Ashing to eliminate interference from dye is necessary in the latter product. 

The method can be applied directly to eye-drops, pessaries, solutions and solution-tablets difficulty is sometimes experienced in recovering the last traces of proflavine in the presence of fatty matter.

Preparations (tablets and injections) are assayed exactly as the parent substance tablet excipients do not interfere but it may be desirable to warm the powdered tablets in the acid to aid solution. Tablets of Sulpha-furazole, B.Vet.C., should be first extracted with dimethylformamide before non-aqueous titration.
