MÜLLER – Berlin Prof. Reinhard NEUBERT – Halle Prof. Christian PEIFER – Kiel Prof. Peter PROKSCH – Duesseldorf Prof. Wiesław SAWICKI – Gdańsk PREFACE Dear Colleagues, Participants of the 7th Polish-German Symposium on Pharmaceutical Sciences Polish-German meetings devoted to presentation of the achievements in pharmaceutical sciences and bilateral cooperation have been organized successfully as long as since 1985. The meetings on the Polish side were initiated by the Pharmaceutical Faculty of Poznań, joined in by the Pharmaceutical Faculties from Kraków and Gdańsk in 2007. It is an honour for us, scientists in the Faculty of Pharmacy of the Medical University of Gdańsk to welcome you in Gdansk at the 7th Polish-German Symposium on Pharmaceutical Sciences. Traditionally scientists from pharmaceutical faculties/institutes in Kiel, Düsseldorf, Halle, Berlin, Poznań and Kraków have been invited to the Symposium. Our invitation to the conference have been accepted by the large group of researchers. We can expect that a special energy will be brought by young scientists, since among 170 participants 61 are Ph.D. students. We do hope that some of them will make an effort in the future to keep going on these important neighborhood meetings for many years. The Symposium is aimed at providing a forum for high level scientific relations between German and Polish researchers working in the area of pharmaceutical sciences. This is the best chance to learn what are the current scientific achievements of the contributing schools of pharmacy and to develop better collaboration among Polish and German researches. Exceptionally friendly atmosphere is a tradition of our meetings and this must help in our future contacts. The leading topic of the symposium is „Interdisciplinary research for pharmacy”. We are sure that not only our honorary speakers, prof. Reinhard Neubert and prof. Roman Kaliszan, but also seven lecturers invited from all participating universities and authors of 164 poster presentations will show how much can be achieved in pharmaceutical sciences if broader interdisciplinary cooperation and new research tools as well as new fields of exploration are considered. The event is taking place in the history-breathing and picturesque Gdańsk. We hope that like for every Polish citizen, also for our German friends this will become a city where one wants to return many times. We wish all participants a joyful but also fruitful time here, with intensive scientific discussions and new contacts.

Reinhard H.H. Neubert Institute of Pharmacy, Martin-Luther-University, Halle (Saale), Germany The outermost layer of the skin, the Stratum corneum (SC) is the main penetration barrier for drugs active ingredients. The SC lipids are playing an essential role concerning drug penetration. Therefore, interdisciplinary research activities are highly necessary for the investigation of the nanostructure of the SC lipids, particularly of the ceramides, is one key research direction in order (1) to understand the barrier function of the human skin and (2) to generate new concepts for influencing dermal and transdermal drug delivery [1 - 3]. In the focus of the lecture are the influence of the ceramides on the nanostructure of the SC lipids and the search for the substantial ceramide subclasses. In the past, results were published concerning key role of the long chain ceramides concerning the barrier function of ther skin. Therefore, influence of the long chain ceramides on the nanostructure of the SC lipids is shown using the CER EOS [4, 5]. Then the impact of short chain ceramides such as CER AP und CER NP is presented. There is a change paradigm because it is shown that the short chain most polar ceramides appear to be essential for the barrier function of the SC. Based on these studies the armature reinforcement model of the SC lipid matrix was proposed: Neutron diffraction results confirm the armature reinforcement model which can be used to illustrate the nanostructure of the SC lipids [4 – 8, 11]. New results were presented in the literature to create the asymmetry model because the SC lipids form asymmetric bilayers in the SC. The short chain ceramides (e.g. the CER NP) have different long alkyl chains (C18 and C24). The asymmetric bilayers consist of one 45 nm bilayer with the C18 alkyl chain and mainly cholesterol molecules and one 65 nm bilayer with the C24 alky chain and mainly free fatty acids. CER NP appears to play a crucial role in the fully extended conformation for the nanostructure of the SC lipids. These results could be confirmed using neutron scattering experiments and a SC lipid model system as well as the Molecular Dynamic Simulation as theoretical method. Furthermore, the influence of lipophilic penetration enhancing molecules (penetration enhancer), e.g. oleic acid and isopropylmyristate on the nanostructure of the SC lipids is shown [9 – 10, 12]. A new interdisciplinary approach is presented concerning the use of the NMR spectroscopy and the lipid monolayer technique [13]. Dynamics of the ceramides inside of the SC bilayers can be studied using different NMR techniques. On the other

Received: 18 December 2013; in revised form: 21 January 2014 / Accepted: 24 January 2014 / Published: 25 February 2014 Abstract: Lubrication plays a key role in successful manufacturing of pharmaceutical solid dosage forms; lubricants are essential ingredients in robust formulations to achieve this. Although many failures in pharmaceutical manufacturing operations are caused by issues related to lubrication, in general, lubricants do not gain adequate attention in the development of pharmaceutical formulations. In this paper, the fundamental background on lubrication is introduced, in which the relationships between lubrication and friction/adhesion forces are discussed. Then, the application of lubrication in the development of pharmaceutical products and manufacturing processes is discussed with an emphasis on magnesium stearate. In particular, the effect of its hydration state (anhydrate, monohydrate, dihydrate, and trihydrate) and its powder characteristics on lubrication efficiency, as well as product and process performance is summarized. In addition, the impact of lubrication on the dynamics of compaction/compression processes and on the mechanical properties of compacts/tablets is presented. Furthermore, the online monitoring of magnesium stearate in a blending process is briefly mentioned. Finally, the chemical compatibility of active pharmaceutical ingredient (API) with magnesium stearate and its reactive impurities is reviewed with examples from the literature illustrating the various reaction mechanisms involved.

Several such pharmaceutical products have appeared in the market for medium dose (Neoral® for Cyclsoprin A, Kaletra® for Lopinavir and Ritonavir), or low dose medications (Rocaltrol® for Calcitriol and Avodart® for Dutasteride). However, these are in the form of viscous liquids or semisolid presentations, characterized by the disadvantages of high production cost, stability problems and the requirement of large quantities of surfactants. Solid SEDDS (S-SEDDS), as coarse powders, granules or pellets, besides solubility improvement, can be filled easily into capsules or processed into tablets providing a handy dosage form with instant release, which can be further developed into controlled release by mixing with suitable polymers or coating with polymeric films. In this review, the materials used for the preparation of S-SEDDS, their properties and role in the formulations are detailed. Factors affecting the physical characteristics, mechanical properties of S-SEDDS as well as their in vitro release and in vivo absorption are discussed. The mechanisms involved in the formation of instant and sustained release self-emulsifying granules or pellets are elucidated.

  • Liquid Filled and Sealed Hard Gelatin Capsules
    The World's Leader in Two-Piece Capsules™ Your Natural Partner ™ Liquid filled and sealed hard gelatin capsules Ewart T. COLE It is generally accepted that many of today’s NCE’s are poorly water soluble and the classical methods, such as reduction in particle size are no longer adequate to achieve satisfactory drug ad- sorption from a solid oral dosage form. Until recently if liquid/semi-solid formulations were necessary the soft gelatin capsule was the only drug form available in which to encapsulate such poorly water soluble drug formulations. This presentation will describe the use of hard gelatin capsules as an alternative for liquid/semi-so- lid formulations. A screening program has been de- veloped from which a list of functional excipients which are compatible with the gelatin shell has been drawn up. Once compatibility has been established the capsules are filled and then sealed by spraying a small amount of a water/ethanol mixture at the cap and body interface followed by a gentle war- ming to fuse the two capsule parts together. The advantages offered by the LEMS™ (Liquid Encapsu- lation by Micro Spray) process over capsule ban- ding will be discussed. It is considered that this technology can make a significant contribution to the development of effica- cious pharmaceutical products by providing the flexibility to rapidly develop and test in-house formu- lations when only small quantities of drug substance is available. The process can be scaled-up and also kept in-house in a similar way to the operations of tabletting or powder/pellet filling of hard gelatin cap- sules.

  • 〈1059〉 Excipient Performance
    BRIEFING 〈1059〉 Excipient Performance. This proposal is based on the version of the chapter official as of May 1, 2018. It is proposed to revise the chapter as follows based on the Excipient Performance 〈1059〉 Expert Panel's recommendations: 1. Change the chapter layout. Because one functional category can be used in multiple dosage forms, remove the dosage form titles under which the functional categories were grouped. Under each functional category create a section titled Dosage Forms that contains a list of dosage forms in which the functional category is generally used. 2. Align types of dosage forms listed in the Dosage Forms sections with those described in Pharmaceutical Dosage Forms 〈1151〉. 3. Divide the pH Modifier (Acidifying/Alkalizing/Buffering Agent) functional category into two functional categories, Acidifying and Alkalizing Agent and Buffering Agent, respectively. 4. Revise the category title Adhesive to Adhesive (Pressure Sensitive). 5. Combine the Capsule Shell and DPI Capsule Shell categories under Capsule Shell. 6. Add 29 new NF functional categories: Air Displacement, Alcohol Denaturant, Antifoaming or Defoaming Agent, Antitack Agent, Biodegradable Polymer, Cationic Dendrimer, Crystallization Inhibitor, Desiccant, Drag-Reducing Agent, Emulsifying Agent, Filtering Aid, Gelling Agent, Humectant, Liposome-Forming Agent, Muco-adhesive, Opacifier, Permeation Enhancer, Physical Form Stabilizer, Physical-Chemical Identifier, Polymeric Membrane, Printing Ink Component, Solvent, Sorbent, Stabilizer, Sugar-Coating Agent, Surfactant, Vehicle, Viscosity-Lowering Agent, and Water-Repelling Agent. 7. Revise the existing functional categories to update any outdated or missing information. Additionally, it is proposed to revise the USP and NF Excipients, Listed by Functional Category reference table , in conjunction with this chapter to reflect the proposed changes to the chapter and to provide a list of excipients grouped on the basis of their functional categories.
