Several reports focus on the effect of formulation factor which directly affected the transfersome’s skin permeability. However, the effect of formulation factors was not fully understood as the contradictory results. To clarify this problem, the reliable statistical techniques, excellent experimental design and systematical variation were used in this study. Transfersomes loaded meloxicam containing controlled amount of phosphatidylcholine (PC), cholesterol (Chol), type of surfactant (hydrophilic part, lipophilic part ) were prepared and investigated for the physicochemical characteristics (e.g., size, size distribution, charge, elasticity, drug content, morphology) and skin permeability.

This is because of their high potency, high specificity and desirable safety profile. The majority of biological drugs are peptide- and protein-based therapeutics with poor oral bioavailability. They are normally administered by parenteral injection (with a very few exceptions). Pulmonary delivery is an attractive non-invasive alternative route of administration for local and systemic delivery of biologics with immense potential to treat various diseases, including diabetes, cystic fibrosis, respiratory viral infection and asthma, etc. The massive surface area and extensive vascularisation in the lungs enable rapid absorption and fast onset of action. Despite the benefits of pulmonary delivery, development of inhalable biological drug is a challenging task. There are various anatomical, physiological and immunological barriers that affect the therapeutic efficacy of inhaled formulations. This review assesses the characteristics of biological drugs and the barriers to pulmonary drug delivery.

  • Hormone Replacement Therapy (HRT)
    Hormone replacement therapy (HRT) The leaflet aims to answer your questions about taking HRT to treat your menopausal symptoms. If you have any questions or concerns, please speak to the doctor or nurse caring for you. This leaflet should be read alongside any patient information provided by the manufacturer. What is HRT and why do I need it? HRT is medication aimed at relieving the symptoms that some women experience during the menopause, also known as the change of life. These symptoms could include hot flushes, night sweats, vaginal dryness, tiredness and irritability, and decreased sex drive. HRT works by replacing the hormone (oestrogen) that your body stops producing when you go through the menopause or when you have had surgery to remove your ovaries. Used long-term, HRT may help to reduce the risk of osteoporosis (thinning of the bones) and bowel cancer. However, there are also known risks including an increased risk of certain types of cancer. These risks are described in more detail later in this leaflet. As new research is available this will be discussed with you in your clinic appointment. When you start HRT, the doctor or nurse will discuss your age, symptoms and medical conditions before looking at the risks and benefits of HRT which are specific to you. These risks and benefits could change and will be discussed at your yearly review. Some women have a medical menopause (a menopause caused by medical treatment) and may be offered HRT. Some women are not able to take HRT – usually these are women with cancers that have been caused by hormones and women who have had a blood clot.

  • A Snapshot of Transdermal and Topical Drug Delivery Research in Canada
    pharmaceutics Review A Snapshot of Transdermal and Topical Drug Delivery Research in Canada Mahdi Roohnikan, Elise Laszlo, Samuel Babity and Davide Brambilla * Faculty of Pharmacy, University of Montreal, Montreal, QC H3T 1J4, Canada; [email protected] (M.R.); [email protected] (E.L.); [email protected] (S.B.) * Correspondence: [email protected]; Tel.: +1-514-343-6111 Received: 1 May 2019; Accepted: 30 May 2019; Published: 1 June 2019 Abstract: The minimally- or non-invasive delivery of therapeutic agents through the skin has several advantages compared to other delivery routes and plays an important role in medical care routines. The development and refinement of new technologies is leading to a drastic expansion of the arsenal of drugs that can benefit from this delivery strategy and is further intensifying its impact in medicine. Within Canada, as well, a few research groups have worked on the development of state-of-the-art transdermal delivery technologies. Within this short review, we aim to provide a critical overview of the development of these technologies in the Canadian environment. Keywords: transdermal drug delivery; Canada; skin; permeation enhancers 1. Introduction The skin is the most accessible organ of the body, stretching over a surface area of 1.7 m2 and making up roughly 10–16% of the total mass of the body [1,2]. Its primary function is to act as a protective layer against environmental hazards such as chemicals, heat, and toxins, as well as to defend the body against invading microorganisms and allergens. Moreover, the skin plays a key role in homeostasis and body temperature regulation, and acts as a sensory organ exposed to the environment, detecting external stimuli such as temperature, pressure, and pain [2].
