Lozenges drying

For dry mouth, suck on hard candy, sugarless lozenges, or small pieces of ice and perform frequent mouth care... 

Lozenges are one of the oldest forms of sugar confectionery, and as they do not involve boiling sugar they are one of the few forms of sugar confectionery that can readily be made at home. Lozenges are simply cut from a sheet of dough and are then dried. 

The stamped pieces are spread out onto trays where a slight crust of dry sugar forms on the surface. The lozenges are then dried at 35-40 °C until... 

Mix the flavour into the dough to taste - as lozenges lose flavour upon drying it is best to be generous with the flavour. 

Sodium Chromous Carbonate, NaaCOj.CrCOj.lOHgO, separates as a reddish-brown powder when moist chromous acetate is mixed with a solution of sodium carbonate in an atmosphere of carbon dioxide. It yields microscopic, tabular, lozenge-shaped crystals. If heated at 100° C. in a current of a dry inert gas, the monohydrate, Na3CO3.CrCO3.H2O, is obtained. 

Benzocaine is a poorly soluble local anesthetic, an ester of para-aminobenzoic acid. It is used in many countries as a component of some free-sale formulations for topical use, for example in skin creams, as a dry powder for skin ulcers, as throat lozenges, and as teething formulations for young children. It is also used in aerosol sprays when anesthetizing the oropharynx. Relatively high concentrations of local anesthetic are required to be effective topically, increasing tissue penetration and the risk of subsequent toxicity. Benzocaine formulations are available in concentrations of 1-20%. 

Sodium borate is used in pharmaceutical applications similarly to boric acid (see Boric Acid). It has been used externally as a mild astringent and as an emulsifying agent in creams. It has also been used in lozenges, mouthwashes, otic preparations (0.3% w/v), and ophthalmic solutions (0.03-1.0% w/v). Sodium borate has additionally been investigated in the prevention of crystal formation in freeze-dried solutions. Preparations of sodium borate in honey have historically been used as paints for the throat, tongue, and mouth, but such use is now inadvisable because of concerns about toxicity in such applications, see Section 14. Sodium borate is also used in cosmetics such as moisturizers, deodorants, and shampoos. 

Noxythiolin (N-hydroxy N-methylthiourea) is supplied as a dry powder and on aqueous reconstitution slowly releases formaldehyde and N-methylthiourea. The compound has extensive antibacterial and antifungal properties and is used both topically and in accessible body cavities as an irrigation solution and in the treatment of peritonitis. Polynoxylin (poly[methylenedi(hydroxymethyl) urea]) is a similar compound available in gel and lozenge formulations. 

Lozenges or hard candy may help mouth dryness. If dry mouth persists for more than 2 weeks, advise provider. 

Fresh herb, freeze-dried or dried herb, and alcoholic extracts are available in the United States in the form of tablets, capsules, lozenges, liquid, tea, and salves. Many products combine echinacea with ginseng, goldenseal, or garlic.

Tablets, lozenges, and dried herbs are also available. Some herbal products can also be found in creams or ointments.

Take a sample of twenty lozenges and determine the average weight. Powder the sample and extract about 0 5 g, accurately weighed, with ether in a continuous extraction apparatus until complete extraction is effected. Transfer the ethereal extract to a separator and wash with three portions, each of 20 ml, of water. Evaporate the ether in a tared flask at a low temperature, dry in a vacuum desiccator and weigh the residue of benzocaine.
