Therapeutic films

Surface coating of mesoporous silicas provides an effective and flexible way for controlled release due to the high drug loading possible and the easy control of release rate. A drug-containing core or tablet is 

Even very thin films of xerogels can release useful amounts of pharmaceutically active material into body fluids and the release kinetics are

Controlled and sustained drug delivery has recently begun to make an impression in the area of treatment of dental diseases. Many researchers have demonstrated that controlled delivery of antimicrobial agents, such as chlorhexidine [128-130], ofloxacin [131-133], and metronidazole [134], can effectively treat and prevent periodontitis. The incidence of dental caries and formation of plaque can also be reduced by controlled delivery of fluoride [135,136]. Delivery systems used are film-forming solutions [129,130], polymeric inserts [132], implants, and patches. Since dental disease is usually chronic, sustained release of therapeutic agents in the oral cavity would obviously be desirable. 

Cationic and hydrophobe modified polysaccharides are preferred excipients for personal care products since they are substantive (adherent) to anionic or hydrophobic substrates (skin, hair, mucosa), hydrophilic, film forming, compatible with many therapeutic agents, nonpenetrating, and nonirritating. Polymer JR and Quatrisoft (Figure 1), are two such materials... 

Uses. As broad-spectrum antimicrobial cold sterilant/disinfectant for hospital equipment as tanning agent for leather as tissue fixative as cross-linking agent for proteins as preservative in cosmetics as therapeutic agent for warts, hyperhidrosis, and dermal mycotic infections in X ray processing solutions and film emulsion as a disinfectant in the beauty industry... 

Mechanism of Action A bulk-producing laxative that decreases surface film tension by mixing liquid and bowel contents. Therapeutic Effect Increases infiltration of liquid to form a softer stool. 

The idea of influencing yourself has come from a self-help book on personal therapy. Tom Rusk and Randy Read, in a postscript to I Want To Change But I Don t Know How (1986), have set out their views on what constitutes best psychotherapeutic practice. Their conclusions are based on extensive observations, using videotape, film, and one-way mirrors, of therapeutic sessions. 

Blending is yet another way of manipulating the polymer properties. PTMC degrades too slowly to be useful for most drug delivery applications. Blends were prepared in an attempt to enhance and control the drug delivery rate [121]. Films were prepared from PTMC and poly(adipic anhydride) (PAA), which were partially miscible and formed macroscopically homogeneous blends. The PAA was found to act as a plasticizer and facilitated the erosion of PTMC by increasing the porosity and hydration. PTMC-PAA blends offered sustained and controllable release of an incorporated therapeutic substance as shown in Fig. 11 [121].
