Biography:

Martha Rowe, Speech Pathologist since 2000 has spent years researching and developing papaya enzyme formulation as a result of her own difficulties with a dry mouth following surgery due to facial trauma in 2008.  She has worked in both Public and Private hospitals across Victoria and has been involved in clinical studies and patients management in the areas of dysphagia and dry mouth.

Abstract:

A dry mouth syndrome occurs when there is not enough saliva (spit) in the mouth. A dry mouth is a symptom of an underlying problem, rather than a disease in itself. Causes may include drugs or medication, dehydration, mouth breathing, Sjogren's syndrome, infection, nerve problems and some cancer treatments.  Our research aims were Investigate effects of papaya enzymes in patients with dry mouth, Create a product that super cedes current products on the market, Determine microbiological and immunological outcomes and Investigate Quality of Life Measures.  Our results found categorically that papya enzymes assist with maintaining a clean and moistened mouth, free of bacteria and assisted with the increase in saliva flow.

Abstract:

The combination of Metformin and Glimepiride is widely used to treat type 2 diabetes. The present study was carried out to study the pharmacokinetic interactions between these two drugs used in combination. An available RP-HPLC method for simultaneous estimation of Metformin and Glimepiride was revalidated for future use. Albino rats of either sex were randomly distributed into four groups of six animals in each; they are housed in well ventilated Aluminium cages and maintained on uniform diet and temperature with 12hr light and dark cycle. In this study, the blood was collected from orbital sinuses using heparinised capillaries into a micro centrifugation tubes contain anti coagulant at 0, 1, 2, 4, 6, 8, 12 hrs after treatment. Plasma was separated by centrifugation and stored at -20ºC until further analysis. These samples are used to analyze for pharmacokinetic and pharmacodynamic toxicological i.e. SGOT-SGPT, Complete Blood Picture (CBP) and serum Creatinine Clearance. Metformin and Glimepiride levels were estimated by a sensitive RP-HPLC method. This study proves, single and multiple doses Metformin increases plasma concentrations of Glimepiride. There is significant increase in the AUC and decrease in clearance. In single dose studies this change could be because of the transient induction in CYP2C9. When Glimepiride is given in repeated doses (15 days) there could be induction of the microsomal liver CYP2C9 subsequently increasing the metabolism, decreasing clearance of Metformin & increasing the overall AUC. This combination has clearly shown the beneficial effect on the CBP  i.e. significant improvement in blood cell count, lymphocytes and neutrophills in particular.

Biography:

Angela Drew is a Product Ideation Consultant at Camargo Pharmaceutical Services. Angela has an academic background in inflammatory diseases and cancer, and a regulatory background in FDA submissions for approval via the 505(b)(2) regulatory pathway. Angela has industry experience with US and Australian regulatory submissions, and experience with global clinical program oversight. She is experienced in Product Ideation and design of drug development programs.

Abstract:

Background: There are 3 major pathways through which drugs can be approved in the US, depending on their similarity to existing drugs, and the source of data that will support the application (see image). The 505(b)(2) regulatory pathway relies to some extent on existing data that comes from sources other than Sponsor studies, and results in smaller development programs than that of previously unknown drugs. A 505(b)(2) approval usually relies heavily on well-designed bioavailability/ bioequivalence studies to bridge to the existing data.

Methodology & Theoretical Orientation: This talk will cover the basics of the US regulatory pathways, with special emphasis on products intended for approval via the 505(b)(2) pathway. Which products are appropriate for this pathway, typical features of 505(b)(2) development programs, and when a biowaiver is appropriate will be discussed. Further, a review of products that gained approval based on studies reported in the literature is provided.

Conclusions & Significance: The 505(b)(2) regulatory pathway allows a Sponsor to rely on existing data and therefore reduce the size or scope of the development program. BA/BE studies are often the tenet of a 505(b)(2) approval, and have distinct goals compared with pharmacokinetic studies conducted for 505(b)(1) or generic products. It is therefore critical that BA/BE studies be designed with the nuances of the 505(b)(2) pathway in mind, and to collect additional data that will further reduce the number of studies required for approval. When BA/BE studies are well designed and conducted, and with FDA feedback and input at the appropriate times, a Sponsor can expect reduced cost and time to market.

Abstract:

Background: Diseases are destroyers of health, well being, and life.  So, Arogya is the main constituent for excelling in life. Jaundice is one disease which has manifested itself as a curse for many years. Even today, there is no good allopathic medicine for treatment and complete cure of jaundice. This study aims to make a formulation for the cure of jaundice by combining various herbals to cure jaundice.

Methods: Based on the ethnomedical literature reviews, the crude drugs such as cardamom, ajowan, cinnamon, coriander, cumin, clove, ginger, and nutmeg were collected and subjected to various pharmacognostical, phytochemical, and analytical studies to assess its quality. After confirming the quality, the hepatoprotective polyherbal formulation (HEP-PRO) was formulated and their efficacy was analysed using various analytical and pharmacological studies. To assess the safety of HEP-PRO, clinical trials were conducted using this formulation at Ayushkaram Ayurveda Hospital, Coimbatore after obtaining Human Ethical Clearance approval by IEC, Institute of Applied Dermatology, Kasaragod.

Results: The present study has been carried out in 30 patients. All the patients were given HEP-PRO at a dose of 60 ml three times a day one hour after food. HEP-PRO provided significant relief in pyrexia by 36% (P<0.015), fatigue and yellow discoloration of sclera by 27 & 39% respectively (P<0.025), and yellow discoloration of urine by 32% (P<0.010). This also has reduced the yellow discoloration of nail and yellow discoloration of skin by 60% with a P value of 0.001, which is also statistically significant.

Conclusion: HEP-PRO has proved its efficacy in the management of jaundice.

Abstract:

Hemorrhoids, also called piles, are vascular structures in the anal canal. In their normal state, they are cushions that help with stool control. They become a disease when swollen or inflamed; the unqualifiedly term "hemorrhoid" is often used to refer to the disease. The signs and symptoms of hemorrhoids depend on the type present. Internal hemorrhoids are usually present with painless, bright red rectal bleeding when defecating. External hemorrhoids often result in pain and swelling in the area of the anus. If bleeding occurs it is usually darker. The new treatment is mainly depend on mechanism of contract the connective tissue surrounding the venous around anus by effervescent tannin base with strong anti-bacterial, antifungal and anti-viral effect of formula. The safety of drugs was tested in rabbits, rats first and then the experiment was done in hundreds of patient under license of ethics committee of Taif University. The percentage of cure conducted was 99%, this success leads to relive of pain over millions of patients around the world and minimize the risk of surgery treatment and cost beside quick relive of disease in two to three weeks with no chance of relapse of disease again.

Abstract:

Regardless of the administration routes, delivery of small molecule drugs to their target sites of action historically poses one of the biggest challenges due to their homogeneous tissue distribution, renal clearance and lack of target specificity. Nanotherapeutics have evolved as novel drug formulations at dimensions of roughly 1–100 nanometers by virtue of the integration of nanotechnology with medicine for treating and preventing critical human diseases effectively and precisely. The favorable pharmacokinetics with prolonged circulation time, selective endothelial permeability at several target tissues and high specificity for biological targets are the attractive attributes of nanopharmaceuticals driving the pharmaceutical industries to conduct a large number of pre- clinical and clinical trials, with enormous successes seen in the past in getting approval and commercialization of nanotechnology-based medical products. Diversified approaches based on synthetic, recombinant, hybridoma and phage display technologies have been undertaken to fabricate a variety of nanoparticulate and macromolecular carriers and drugs in order to overcome the multi-step extracellular and intracellular barriers and to facilitate development of novel strategies for therapeutic delivery and imaging.

Abstract:

The sale of antibiotics without medical prescription has been observed in many countries. The practice is more pronounced in developing and low income countries where legislations and regulations are weak. In these countries, antibiotics are illegally purchased without medical prescriptions and very little effort has been made to tackle the situation. The role of pharmacists in contributing to healthcare remains debatable. In Ethiopia, there are deficiencies in the quality of current professional practice. Community pharmacists are now seen as retailers and businessmen rather than health care providers. Ethiopians are therefore left to accept the helpful and harmful practices such pharmacists. Self-medication with antibiotics is a universal problem and variations regarding such practices are obvious around the globe. The practice cuts across culture, gender, age, health status, social status, race and occupation. Irrational use of antibiotics increases the risk of bacterial resistance and adverse drug reactions. It has been found to produce various adverse effects in humans. It is the objective of this paper to discuss the irrational use and non-prescription sale of antibiotics in Ethiopia. It will discuss the evidence, the concept of self-medication, resistance and interactions, legislation, probable solutions, changes
in practice and the concept of sustainability which would help guarantee the appropriate sale and rational use of antibiotics in Ethiopia.

Abstract:

Health care waste disposal is an alarming issue in these days. Improper disposal of injections and sharp wastes at open places exposes people to the risk of transmission of infectious diseases. Inappropriate methods of managing, treatment and disposal of health care waste can lead to an adverse effect on public health. This study highlights the unsafe disposal of injection and sharp waste in Rawalpindi, Pakistan. This study is conducted to explore the injection and sharp waste disposal practices at the community level clinics. In-depth scientific analysis study including the interviews of sanitary workers working in different community clinics is conducted. 65% claimed that they disposed of waste (syringes, swabs, dressings, needles) which they collected from clinics at open places and 35% stated that they dispose of waste in municipal bins. None of them has ever got training regarding injections and sharp waste disposal. Only 25% sanitary workers were aware of the hazardous effect of unsafe disposal of injection and sharp waste. 75% stated that they get injured one or more time while disposing of syringes. The reasons they stated of having injury were lack of time, lack of awareness regarding the transmission of infectious disease. There is an urgent need to develop safe and sustainable waste disposal method that is feasible at the clinic level. It is found that injections and sharp wastes from clinics are handled and disposed of together with domestic waste.  It is also concluded that the duty of health care waste disposal is delegated to illiterate people who perform their duties without adequate knowledge and protective measures. Therefore, it is recommended that government and local health authorties should give immediate attention to this issue and setup a proper sustainable clinic waste disposal system.

Abstract:

Background: The use of menopausal hormone replacement therapy in Australia declined by 55% from 2001 to 2005 following the publication of the Women’s Health Inititive trial findings, which highlighted an increased risk of breast cancer (Velentzis et al., 2016). In 2010, an estimated 539 cancers in Australia were attributable to menopausal hormone therapy, 453 breast (3.4%), 67 endometrial (3.1%) and 19 ovarian cancers (1.6%) (Jordan et al., 2015). It was further estimated that if 25% less women used hormone therapy 141 cancers would be prevented and the sole use of estrogen only products would prevent 240 cancers.

Aim: To explore the relationship between the use of menopausal hormone therapy and pre-exiting non-modifiable breast cancer risk factors; personal or family history, early menarche or low parity. It was based on analysis of questionnaire data collected by the BreastScreen Queensland programme.

Results: A positive personal history of breast cancer did not significantly influence the use of HRT, OR 1.117 (95% CI, 0.8945 – 1.3930), p=0.3274. However, women with a positive family history of breast cancer were less likely to have used any HRT compared to those with no family history, OR 0.8528 (95% CI, 0.7635 – 0.9526), p=0.00478. No significant difference in HRT use was noted between mothers and non-mothers, OR 1.101 (95% CI, 0.9702-1.2490), p=0.1360.

Conclusion: Of the examined non-modifiable breast cancer risk factors, only a family history influenced the use of HRT. The pre-existence of non-modifiable breast cancer risk factors has a minimal effect on the pattern of HRT use amongst women in Queensland.

Abstract:

Natural colorants are used in the coloration of food, handicraft items, toys, textiles and in leather processing. Many of the color-yielding plants are used as medicines in various traditional medicinal systems. Interest for natural colorants has increased dramatically worldwide due to the awareness of possible toxicity that can be caused by modern synthetic dyes. Synthetic colors have been banned in certain countries due to allergic and carcinogenic symptoms that they can cause. More eco-friendly colorants are now being developed to replace synthetic dyes which can be toxic and hazardous to health. Thus, the researchers wanted to study natural colorants from three botanical sources namely, Areca carechu, Bixa orellana and Hibiscus rosa-sinensis as possible alternative for the commercially used Food, Drug and Cosmetic colorant, Allura Red. UV-Vis Spectrometry was used to measure the transmittance of the samples which were used to obtain their CIELAB values and to compare the colorants quantitatively. Natural colorant from Areca catechu, Bixa orellana, and Hibiscus rosa-sinensis mean L* values were 21.6097, 44.3664 and 19.0708 respectively; mean a* values were 89.2146, 65.3665 and 69.7741 respectively; and mean b* values were 99.0016, 110.3789 and 21.6674 respectively. These results revealed that the natural colorants from Areca catechu, Bixa orellana, and Hibiscus rosa-sinensis all fall within the dark, red and yellow spectra of colors. Using One Way Analysis of Variance (ANOVA), it was found out that both the natural colorants from A. catechu and B. orellana yielded p-values of 0.042 and 0.024 respectively. These are both lower than the level of significance at µ 0.05 which means that there is a significant difference between the combined CIELAB values for color characterization of the natural colorants obtained from A. catechu and B. orellana to that of Allura Red. Thus it can be inferred that they can’t be utilized and further studied as possible alternative colorants to Allura Red. Only H. rosa-sinensis yielded a p-value of 0.641 that is greater than the level of significance at µ 0.05. This means that there is no significant difference between the combined CIELAB values for color characterization of the natural colorant obtained from Hibiscus rosa-sinensis to that of the standard, Allura Red making it a potential alternative. It can also be inferred through such data that among the three natural colorants that were analyzed in this study, the natural colorant from H. rosa-sinensis is the closest to Allura Red in term of combined color characteristics.

Abstract:

Meliaceous limonoids, characteristic chemical markers of the Meliaceae family, are natural products with both fascinating structures and potential bioactivities that have attracted interest from both natural products chemists and synthetic chemists in the past half century. As part of a continuing search for structurally interesting and biologically important limonoids from the Meliaceae family, the leaves and twigs of Trichilia sinensis collected from Xishuangbanna, Yunnan province of China were investigated. Trichilia sinensis Bentv, a shrub, is native to the south of China and Vietnam, and it has traditional applications for the treatment of several diseases such as abdominal pain caused by Ascaris lumbricoides, chronic osteomyelitis, scabies, and eczema in folk medicine. The three novel rearranged mexicanolide-type limonoids (Trichiliasinenoids A-C) with an unprecedented C-29-C-7 connecting carbon skeleton formed by migration of C-7 from C-6 to C-29 of a mexicanolide-type limonoid precursor were isolated from the leaves and twigs of Trichilia sinensis. Their structures were assigned by spectroscopic analysis, and the absolute configurations were determined by X-ray crystallography and CD calculation. A possible biosynthetic pathway of Trichiliasinenoids A was also proposed. The three new limonoids were evaluated for their cytotoxic activity against human myeloid leukaemia (HL-60), hepatocellular carcinoma (SMMC-7721), lung cancer (A-549), breast cancer (MCF-7), and colon cancer (SW480) cell lines by MTS assay. Trichiliasinenoid B showed cytotoxicity against HL-60 cells, SMMC-7721 with an IC₅₀ value of 5.2 mM and 30.6 mM, respectively, whereas other limonoids were inactive  and comparable to the cisplatin positive control (IC₅₀: 1.1–17.3 m M).

Abstract:

Objective: This study aimed to identify the incidence of risk factors and the utilization of thromboprophylaxis for perioperative venous thromboembolism (VTE) in patients undergoing spine surgery using National Health Insurance claims data in Korea.

Methods: The incidence of VTE in adult patients with spine surgery was extracted from 2014 National Inpatient Sample dataset provided by the Health Insurance Review & Assessment Service (HIRA-NIS-2014), a sample of all patients using medical services in Korea. The association of patient and surgery procedure variables, including VTE prophylaxis were determined with multivariable logistic regression

Results: In 2014, total incidence of VTE was found to be 1.5% (314) among 20,900 spine surgeries in Korea. Multivariable logistic regression analysis identified several independent predictors of VTE, including age over 80, length of stay (over 10 days), vein diseases, cancer, prolonged surgery (over 2 hours), perioperative blood transfusion (over 2 liters), cardiovascular diseases, and respiratory diseases. Only 5.7% of total spine surgeries is provided with VTE prophylaxis.

Conclusion: Patients undergoing spine surgery in Korea represent a population at a higher risk for VTE, however, relatively less concerned by care providers. Understanding the risk factors associated with perioperative VTE in spine surgery may provide an opportunity for early intervention and risk stratification in this population.

Abstract:

Starch is the most commonly used pharmaceutical disintegrant in tablet formulations. The aim of the present study was to assess the disintegrant property of Ethiopian potato (Plectranthus edulis) starch in comparison to Irish potato starch and its optimization in paracetamol tablets formulations - prepared by wet granulation method. Tablet properties such as crushing strength, friability, disintegration time, and dissolution rate of the tablets were studied for both comparison and optimization studies. The results of comparative study showed that the properties of paracetamol tablets formulated with both starches as disintegrants were affected by their concentration and the compression force (CF); and P. edulis starch exhibited a favorably comparable disintegrant property with Irish potato starch in paracetamol tablet formulations. The study also showed that the CF and disintegrant concentration had significantly affected the response variables (i.e., the crushing strength, friability and disintegration time); hence, these factors were further optimized using central composite statistical design. The optimal conditions were obtained at a CF of 14.40 KN and disintegrant concentration of 5.96%. Under these conditions, the crushing strength, friability and disintegration time were 101.8 KN, 0.3% and 1.34 min, respectively. These values closely matched with the predicted values of the responses at the aforementioned levels of the factors. Thus, the results of this study indicated that Ethiopian potato (P. edulis) can be used as an alternative source of starch for its application as a disintegrant in the tablet formulations.
