6. Prolonged Drug Release from Gels, using Catanionic Mixtures
Sammanfattning : The use of catanionic drug-surfactant mixtures was proven to be an efficient novel method of obtaining prolonged drug release from gels. It was shown that various commonly used drug compounds are able to form catanionic mixtures together with oppositely charged surfactants. LÄS MER
7. New Concepts in Administration of Drugs in Tablet Form : Formulation and Evaluation of a Sublingual Tablet for Rapid Absorption, and Presentation of an Individualised Dose Administration System
Sammanfattning : This thesis presents two new concepts in oral drug administration and the results of evaluation of some relevant formulation factors.Investigation into improving the homogeneity of mixtures for tableting indicated that it may be possible to obtain interactive dry mixtures of micronised drugs containing drug proportions as low as 0.015% w/w.

8. Discovery of N-hydroxyguanidines as novel electron acceptors of xanthine oxidase : Potential new drugs for treatment of ischemia and reperfusion injury
Sammanfattning : Xanthine oxidase (EC 1.1.3.22) is one of the major enzymatic sources of oxygen-derived free radicals. LÄS MER
9. Catanionic Aggregates in Gels : Prolonged Drug Release and Potential Implications for Topical Use
Sammanfattning : Gels are popular dosage forms. This topical dosage form may be advantageous compared to oral or parenteral dosage forms. Favorable rheological or bioadhesive properties of gels might provide extended contact times at the site of administration compared to aqueous solutions. LÄS MER
10. Spray-Dried Powders for Inhalation : Particle Formation and Formulation Concepts
Sammanfattning : Spray drying is a method with a high potential in the preparation of protein particles suitable for pulmonary delivery. However, surface induced denaturation of bio-molecules during atomization and subsequent drying can be substantial and it is therefore important to develop new formulation concept for concurrent encapsulation and stabilization of proteins during spray drying.
