    Study Notes

    Adverse Drug Reactions (ADRs)

    • An ADR is a response to a drug that is noxious and unintended and occurs at doses normally used in humans for prophylaxis, diagnosis or therapy of disease, or for modification of physiological function (WHO 1972)

    Medication History

    • Check the Australian Medicines Handbook (www.amh.net.au) as the first source, then use the Australian Drug Information (Aus DI) site if needed

    More Drugs – More ADRs

    • The more drugs a patient takes, the higher the risk of ADRs

    Medications with Hyposalivatory Effects

    • Anti-hypertensives
    • Narcotic analgesics
    • Anti-spasmodics
    • Anti-convulsants
    • Systemic bronchodilators
    • Anti-emetics
    • Anti-nauseants
    • Skeletal muscle relaxants

    • Expectorants
    • Decongestants
    • Tranquillisers
    • Sedatives
    • Anti-neoplastic agents

    Anti-Coagulant vs Anti-Platelet Medication

    • Anti-platelet medication inhibits platelet aggregation through various methods
    • Anti-coagulant medication affects coagulation factors to impede thrombosis/coagulation cascade after initial platelet aggregation

    Common Anti-Coagulant Pharmacokinetics

    • Warfarin (Coumadin/Marevan)
      • Route: Oral
      • Frequency: Daily
      • T Max: 4 hours
      • Half Life: 20-60 hours
      • Metabolism and Elimination: Almost entirely hepatic
      • Reversal: Vitamin K
    • Dabigatran (Praxada)
      • Route: Oral
      • Frequency: Twice daily
      • T Max: 2 hours
      • Half Life: 12-17 hours
      • Metabolism and Elimination: Renal (80%) and Hepatic (20%)
      • Reversal: Idarucizumab
    • Rivaroxaban (Xarelto)
      • Route: Oral
      • Frequency: Once daily
      • T Max: 2.5-4 hours
      • Half Life: 5-9 hours (healthy) and 11-13 hours (elderly)

      • Frequency: Twice daily
      • T Max: 1-3 hours
      • Half Life: 8-15 hours
      • Metabolism and Elimination: Renal (27%) and Hepatic (73%)
      • Reversal: Andexanet alpha

    Warfarin

    • Most widely used anticoagulant in the world
    • Synthesised in 1948
    • Used as a rodenticide in the USA in 1952
    • Human use began in 1954
    • Vitamin K Antagonist – Affects Factor II, VII, IX, and X

    NOAC (or DOAC) Therapy

    • AKA Non-Vitamin K antagonist Oral Anti-Coagulant Therapy
    • AKA Novel Oral Anti-Coagulant Therapy
    • AKA Direct Oral Anti-Coagulant
    • Selective in Coagulation Factor Inhibition (Eg. Dabigatran inhibits Factor IIa/Thrombin)
    • Higher compliance and lower side effect profile (?)
    • No blood test needed/possible

    Foods/Supplements with Blood Thinning Effects

    • Licorice

    Medical History and Risk Assessment

    • Importance of medical history in dental treatment planning

    • Screening patients prior to anti-resorptive and anti-angiogenic medications
    • Understanding risk factors for IV vs. oral bisphosphonates and medical reasons for taking bisphosphonates
    • Up to 3-fold decrease in MRONJ incidence with preventive dentistry
    • Risks of MRONJ can be discussed prior to drug therapies, emphasizing good oral hygiene

    Medical Conditions

    • Multiple Myeloma (MM): history, medications, and impact on dentistry
    • Type 2 Diabetes: episodes of hypoglycaemia, medications, and impact on dentistry
    • Chronic Kidney Disease: stage IIIA, medications, and impact on dentistry
    • Hypertension: diagnosis, medications, and impact on dentistry
    • Osteoporosis: vitamin D deficiency, medications, and impact on dentistry
    • Gastric Oesophageal Reflux Disease (GORD): secondary effect to MM treatment
    • Prostamegaly: secondary effect to MM treatment

    Medications

    • Venlafaxine (Effexor): antidepressant, selective serotonin-norepinephrine reuptake inhibitor
    • Lithicarb (lithium carbonate): treatment and prophylaxis of mania, manic depressive illness, and recurrent endogenous depressive illness
    • Spironolactone (Aldactone): treatment of fluid build-up due to heart failure, liver scarring, or kidney disease
    • Atenolol (Tenormin): beta-blocker, treatment of angina and hypertension
    • Lipex (simvastatin): treatment of hypercholesterolemia and hyperlipidaemia, prevention of coronary heart disease
    • Alendronic acid (alendronate sodium, Fosamax): bisphosphonate, treatment of osteoporosis, osteogenesis imperfecta, and bone diseases

    Treatment Planning Phases

    • Systemic Phase
    • Acute Phase
    • Disease control Phase
    • Definitive Phase
    • Maintenance Phase

    Importance of Medical History

    • Understanding medical history helps tailor treatment towards the patient's needs and goals
    • More information leads to less unpredictability
    • Understanding medical history and performing risk assessments is crucial for a Dental Clinician

    Medical History

    • Multiple Myeloma (MM): diagnosed in 2017, currently in remission, previously treated with IV Zoledronic Acid, Prednisone, and Chemotherapy
    • Type 2 Diabetes Mellitus (NIDDM): diagnosed in 2019, with episodes of hypoglycaemia, treated with Insulin Aspart Protamine Suspension and Gliclazide
    • Chronic Kidney Disease: Stage IIIA, secondary to MM treatment, eGFR – 51 ml/min, treated with Dutasteride – Tamsulosin (Duodart) and Ceased oxybutynin
    • Hypertension: diagnosed prior to 2000, treated with Perindopril (Coversyl), Metoprolol (Minax), Lercanidipine (Lercadip), and Atorvastatin (Lipitor)
    • Osteoporosis: diagnosed with Vitamin D deficiency, treated with Vitamin D + Calcium (Ostevit-D)
    • Gastric Oesophageal Reflux Disease (GORD): secondary effect to MM treatment, previously treated with pantoprazole and sodium bicarbonate capsules
    • Prostamegaly: secondary effect to MM treatment, treated with Baclofen (Gablofen)
    • Hypothyroidism: with low energy, depression, and fatigue, treated with thyroid supplements

    Antibiotic Prophylaxis

    • National Institute for Health and Clinical Excellence (NICE) guidelines (2008): cessation of antibiotic prophylaxis for patients at risk of infective endocarditis (IE) for any invasive dental procedure
    • Risks of adverse events versus risk of IE

    Therapeutic Guidelines

    • 2008: Australian Therapeutic Guidelines
    • 2019: Therapeutic Guidelines – Dental Procedures Indicated

    Lifestyle Choices and Risk Factors

    • Cardiovascular Disease: antibiotic prophylaxis may be required in certain cases
    • Prevention: dental clinicians should screen patients prior to the use of anti-resorptive and anti-angiogenic medications
    • Risks of MRONJ can be discussed prior to drug therapies, ensuring patients understand the reason for good oral hygiene
    • Up to 3-fold decrease in incidence of MRONJ with patients undergoing preventive dentistry
    • Reduction in MRONJ incidence for cancer patients with IV bisphosphonates

    Oral Side Effects of Radiation Therapy (RT)

    • Short-term effects: mouth ulcers (mucositis), hyposalivation/xerostomia, loss of taste (dysgeusia)
    • Long-term effects: hyposalivation/xerostomia, radiation caries, osteoradionecrosis, periodontitis, trismus

    Dental Pre-Assessment Goals

    • Prepare patient for short-term and long-term side effects of cancer therapy
    • Minimise interruption of cancer treatment from acute dental concerns
    • Prevent future complications (e.g. osteoradionecrosis)
    • Develop an appropriate preventive regime to counter increased challenge to oral structures from oncology treatment

    Dental Treatment Plan

    • Minimise interruption of cancer treatment
    • Prevent future complications
    • Develop an appropriate preventive regime
    • Remove existing foci of infection
    • Stabilise periodontal disease
    • Develop a preventive regime (e.g. twice daily toothbrushing, high fluoride toothpaste, baking soda mouthrinse)

    Risk Factors for Oral Cancer

    • Lifestyle risk factors: smoking, alcohol
    • Immunosuppression: immunosuppressant use in autoimmune disease, HSCT/organ transplant

    The Dentist's Role

    • Early detection
    • Support through treatment
    • Post-treatment maintenance
