Provided is a water-soluble film for molding a packaging capsule which is capable of enclosing chemical agents especially a detergent, has a robust property that prevents leakage of the detergent through suitable thickness and strength and an easy-processing property that keeps robustness not to make a drawn portion break in mold-processing such as deep drawing, further has a soluble resistance that does not make the chemical agent elute within 30 seconds in water at 20° C. and a complete-solubility property within a short period of time in dish-washing and clothes-washing, also has sufficient solubility and complete-solubility properties for film portions around the perimeter edge pasted with a water-soluble film for a top, and exhibits a strong-sealing property to have a temporal stability.

A water-soluble film comprises one or more kinds of anion-group-modified polyvinyl alcohols including repeating units from a fatty acid vinyl ester comonomer and anion-group-containing repeating units, in which a degree of saponification thereof is set from 91 mol% or more to 99 mol% or less and a degree of modification by anion groups is set from 1.0 mol% or more to 6.0 mol% or less so that an amount of anion-group modification is set from 1.0 mol% or more to 3.5 mo%l or less to a total amount of the anion-group-modified polyvinyl alcohols, and are formed by including less than 45 parts by mass of a plasticizer per 100 parts by mass of a total amount of the anion-group-modified polyvinyl alcohols, and have a tensile modulus of 100 MPa or less.

This invention provides compositions for controlled localized depositing of one or more drugs within a subject. More particularly, described herein are compositions comprising a) a polyethylene glycol (PEG) composition having a first low molecular weight PEG (Mw between 200-500 Da) and a second low molecular weight PEG (Mw between 500-2000 Da) and b) a mucoadhesive in polymer. Alternatively, composition may comprise a) a polyethylene glycol (PEG) composition having a first low molecular weight PEG (Mw between 200-500 Da) and a second low molecular weight PEG (Mw between 500-2000 Da), b) a water insoluble polymer and c) a mucoadhesive polymer. Furthermore, the composition may further comprise one or more drugs. Also provided are methods of manufacturing and administering the compositions described herein, which are used as biodegradable, injectable mucoadhesive low-viscosity pastes.
