First of all, I would like to express my deepest gratitude to my supervisor Prof. Dr. Gerhard Winter for giving me the opportunity to join his research group and to work on this extremely interesting and interdisciplinary project. I really appreciated his scientific input throughout all phases of this work, his elaborate advice and his guidance, which also contributed to my personal development over the last years. Furthermore, I would like to thank him for the outstanding working and team atmosphere, which he created at the chair, for supporting my participation in scientific conferences and for initiating and motivating me to the numerous collaborations which contributed to a successful thesis. I would also like to thank Prof. Dr. Wolfgang Frieß for all the helpful and interesting discussion in the past years, as well as for being the co-referee of this thesis. Thank you for creating the pleasant working conditions together with Prof. Dr. Gerhard Winter. Many thanks also go to Prof. Dr. Olivia Merkel, Dr. Gerhard Simon and Sabine Kohler. This interdisciplinary work would not have been possible without the support of many cooperation partners, who contributed enthusiastically to this thesis. I would like to thank the group of Prof. Dr. Mathias Ritzmann and especially Dr. Christine Weiß from the Clinic for Swine at the LMU (Oberschleißheim) for their continuous support with pigs and pig skin throughout the course of this thesis.

  • North of England Guidance for Long Acting Antipsychotic Injections July 17
    Guidance on the Use of Antipsychotic Long-acting Injections in North of England (TEWV version) This guidance aims to inform and support prescribers within the three mental health service providers in the north of England in the cost-effective use of antipsychotic long-acting injections. Long-acting or “depot” injections are a useful and well-established form of administering antipsychotics in the management of schizophrenia and other psychoses. The introduction of long-acting formulations of second-generation (atypical) antipsychotics has created an additional pressure on drug budgets in mental health services, which may be justified if their use results in reduced hospital admissions, shortened length of stay and improved quality of life compared with the first generation (typical) agents. Advantages of long-acting / depot injections Assured compliance with antipsychotic treatment Increased bioavailability (less first-pass metabolism) Steady plasma levels compared to oral medication Reduction in relapse rate, severity of relapse and rehospitalisation Stable therapeutic effects Better downward titration to minimise side-effects There is some evidence that long-acting injections cause less brain tissue loss and deterioration (CATIE study1) Disadvantages of long-acting / depot injections Treatment cannot be stopped quickly if severe side-effects develop (dystonia, EPSE, NMS) Perception by the patient of “being controlled”, losing control over their treatment, or possibly being punished. Pain at the site of injection, lasting possibly 10 days Tissue necrosis - over time hard plaques may form, which will reduce the ease of administration and the efficacy of the injection as well as causing discomfort. Loss of dignity with the gluteal route Over and above these factors, NICE2 recommend that consideration should be given to offering a depot / long-acting injectable antipsychotic to people with psychosis or schizophrenia who express a preference for such treatment after an acute episode.

Kshirsagar , Abhijit G. Kalbande a Student- Pooja A. Kshirsagar, PRMCEAM, Bandera, Amravati, Maharashtra b Lecturer - Abhijit G.Kalbande, PRMCEAM, Bandera, Amravati, Maharashtra ABSTRACT: The Painless Injection Technology play the important role in our life because in our country we have seen the so many people who are having a phobia for giving an injection which has a needle, that’s why in Painless Injection Technology we used the needle free injection. This painless injection has the electronic circuit for making injection devices. Today, this is a very rising technology that avoids the pain and infection having needle based injection. This painless injection technology is very easiest way to delivering the vaccines into skin. Keywords: Needle Free,Injection,Phobia,Technology,Vaccine,Drug I. INTRODUCTION Since 150 years we have seen the needle based injection for giving an injection into the skin. They form the major part of perenteral dosage form [1, 2]. To overcome problems related to needle based injection there is one technology that has received constant attention during the past few years that has all of the sought after benefits i.e. Needle free injection. The needle free injection don’t have needle but make use of electronic circuit to drive drugs through skin. These needle free injections are available in the form of power sprays, edible products, Inhaler’s and skin patches [1, 3].
