Summary Lecture Gout/Glaucoma Learning Outcomes • • • • • Predict the activity of a drug based on its structure & physiochemical properties Demonstrate an understanding of how the physical & chemical properties of a drug determine its pharmacology,toxicology,bioavailability and behaviour in formulations Identify typical example of drugs which are used to restore physiological functions in gout & glaucoma Describe the mechanism of therapeutic action of a selected drug at the molecular,cellular,organ system and whole body levels Describe the common adverse effects of a selected drug & their mechanism of production Learning Outcomes • Demonstrate an understanding of basic metabolism in relation to drugs & efficacy & safety in relation to the treatment of disease and/or maintenance of health • Have an awareness of the risk factors & prevalence of gout & glaucoma so as to identify & refer presentations in the pharmacy appropriately Learning Outcomes • Demonstrate an understanding of the clinical & therapeutic principles of treatment of gout & glaucoma • Be aware of the pharmacological & non-pharmacological aspects of managing patients with gout & glaucoma Inflammation • Be aware of the cell types involved in inflammation • Be aware of the inflammatory mediators • Understand the multiple roles of the prostanoids Allergy • Understand the different grades & associated symptoms of allergy • Classification of allergic anaphylactic reactions • Types of hypersensitivity • Role of IgE • Delayed reactions and Allergy • Be familiar with appropriate treatments for allergy • Understand the cross-reactivity that may exist between sulfonamide antibiotics and other sulfonamide drugs • Be familiar with commonly use drugs containing a sulfonamide moiety Non-selective & selective COX-2 inhibitors • Understand the role COX-1 & COX-2 play in the physiological & pathophysiological process of inflammation • Be familiar with the arachidonic acid cascade Selective COX-2 Inhibitors • Understand the clinical & molecular differences between a non-selective & selective COX-2 inhibitor • Understand the how binding by NSAIDs,COX-1 & COX-2 in the arachidonic acid cascade allows pharmacological targeting due to structural differences Gout • Understand the clinical features of gout • Be familiar with serum urate concentrations for hyperuricaemia in males & females • Understand the difference between uric acid & urate Gout • Understand the causes of hyperuricaemia • Be aware of the risk factors of gout • Knowledge of which medications may be predisposing to causing gout Treatment of gout • Knowledge of medications to treat & avoid in the acute attack of gout • Be aware of the revised dosing recommendations for colchicine in acute gout • When to avoid or reduce the dose of NSAID’s or colchicine & possible drug interactions Maintenance of gout • Urate lowering drugs available • Role of xanthine oxidase • Dose limitations in renal impairment • Understand the rationale behind separating the treatment of acute attacks from introducing urate lowering measures • Knowledge of correctable factors to treat Glaucoma • Understand the relevance of elevated intraocular pressure in the diagnosis of glaucoma • Pathological features • Types of glaucoma • Risk factors Treatments available to manage glaucoma • For each of the different classes of eye drops to treat elevated IOP be familiar with their mechanism,efficacy,order of treatment,precautions & contraindications & interactions • Understand the need for simplified dosing regimes,individualised education to improve adherence & reduce the risk of blindness Use of eye drops • Be able to instruct the patient on the correct instillation of eye drops • How to minimise microbial contamination • How to minimise side effects
