Abstract: Anionic surfactants are used in conjunction with an antifungal acid and a chelating agent to preserve topically administrable pharmaceutical compositions without the need for a conventional preservative such as benzalkonium chloride.

Abstract: Anionic amino acid based surfactants are used to enhance antimicrobial effectiveness in topically administrable pharmaceutical compositions containing at least one active ingredient, a cationic preservative and an anionic polyelectrolyte, such as carboxyvinyl polymers, xanthan gum, polystyrene sulfonic acid polymers and cationic exchange resins.

Abstract: Disclosed are preservative systems useful in aqueous pharmaceutical compositions containing an active agent and a cyclodextrin. The preservative systems comprise boric acid and one or more compounds selected from the group consisting of C.sub.16 benzalkonium halide compounds, polymeric quatemary ammonium compounds, and quatemary ammonium alkylene glycol phospholipid derivatives of the following structure ##STR1## where a+b=3; R.sup.1 is C.sub.8 -C.sub.22 alkyl or alkene; X is NH, O, or CH.sub.2 ; R.sup.2 is C.sub.2 -C.sub.6 alkyl; each R.sup.3 is independently C.sub.1 -C.sub.12 alkyl or alkene; and Y is nothing or C.sub.1 -C.sub.6 alkyl or alkene; and pharmaceutically acceptable salts thereof.

Abstract: Stable formulations of positively charged, hydrolytically unstable drug compounds are obtained by adding a sulfated polyvinyl alcohol copolymer to the formulations.

Abstract: Certain anionic surfactants are used to enhance antimicrobial effectiveness in comfortable, sustained release ophthalmic compositions containing polyelectrolytes, such as carboxyvinyl polymers, polystyrene sulfonic acid polymers and cationic exchange resins, as well as at least one active ingredient.

Abstract: Solid dosage forms of bioactive materials for parenteral administration such as porcine or bovine somatotropin pellets intended for subcutaneous implantation to improve food production of farm animals are coated with polyvinyl alcohol to extend the release characteristics of the material. The polyvinyl alcohol preferably has a molecular weight of from about 20,000 to 100,000, a degree of hydrolysis of at least about 98%, and is applied from an aqueous solution by spray coating to form a continuous uniform covering of from about 3 to 25 ug PVA/mm.sup.2 surface area of pellet.
