Karten in diesem Stapel (20)
- 1Complementary/ alternative medicines (CAM)Wide range of therapies and procedures
comp: used with standard medical treatments
alt: used instead of standard medical therapy - 2CAM facts50% of australians use them
particularly patients with chronic diseases: cancer, arthritis, chronic pain, AIDS, GI probelms - 3CAM Herbals/ vitaminsst johns wort, selenium for AIDS, vitamins used most
- 4Pregnancy/labourraspberry leaf, ginger
- 5UTIScranberry juice, BUT interaction with warfarin
- 6COLDS/FLUechinacea, BUT allergic reactions possible
- 7DepressionSt john's wort, BUT drug interactions with SSRIS = SERTONIN SYNDROME
- 8Issues with CAM aes:hepatoxicity, nephrotoxicity, strokes.
contain contaminants (heavy metals, toxins, drug contaminants) - 9Issues with CAMPatients do not inform health professional they are using CAM "Viewed as healthy"
- 10Therapeutic goods administrationinternational sale not regulated, some medicine exempt
- 11Where drugs produce toxicityall organs of body,
particularly in liver, blood, kidney (altered perfusion/function)
gut (ulcers)
all are exposed to drug or conc of drug as part of metabolism or excretion - 12Drug induced liver injury1. intrinsic hepatotoxins: predictable, dose-related toxicity paracetomol
2. hypersensitivity: hepatotoxins e.g. halothane, unpredictablem dose-unrelated, rare
3. cholestatic hepatotoxicants: e.g. ethanol: cessation of bile flow/formation = jaundice - 13Adverse drug reactionsnoxious and unintended drug response which occurs at therapeutic doses
- 14Type A ADRSaugmented, over- extension of drugs intended action, common, usually predicatable and reversible e.g. postural hypotension with antihypertensives
- 15Type B ADRS:Bizzare, uncommon, usually unpredicatble and not dose related, often severe with high morbidity/mortality e.g. penicillin anaphylaxis
- 16ADRs exponentiallyincrease with more than 4 concurrent medications (drug interactions)
- 17ADRScan be due to drug interactions, diet, CAM interations
PK related / PD related - 18Examples of ADRS from interactionsPK: viagra and grapefruit juice or terfenadine and antifungals 'azoles'
PD: angina drugs (nitrates) and viagra
Complementary medicines and drugs: St John's wort and anti-coagulants (PK-related therapeutic failure) or SSRIs (Serotonin syndrome) - 19General approach to deliberate self poisoningresus
