New Drugs and Testing Is regulated by the FDA- Federal Drug Administration which is concerned with general safety, standards in production of drugs, food and cosmetics. They are responsible for adding or removing drugs from the market 1978 Drug Regulation and Reform Act decreased time periods for drug testing (must have informed consent) 1. Animal testing Can only assess toxic and therapeutic levels. Study absorption and metabolism and kidney excretion with these studies. Adverse reactions. 2. Human testing Okayed only after the animal studies. Must have voluntary informed consent. The Nuremburg code is ethical codes enacted due to the human study by Nazi Germany during the Holocaust. The benefit/risk ratio is considered and if at any time they feel it is too risky they will pull the study. They must use both healthy and ill patients and must use drug for some and placebo for others. Double blind testing. Generic Drugs Pharmaceutical companies that develop a drug give it a trade name. (Valium, Demerol) The drug also has a generic official name (diazepam, meperidine) Drug also a chemical name To recoup the money for drug development, only the developing pharmaceutical company can market the drug for a specified number of years under the trade name for 17-20 years 1984- Drug Price Competition and Paten Term Restoration Act: said that when the patent of a trade period is over, generic drug companies can market the drug by showing bioequivalence (absorbs and acts the same as the original drug) Can’t be called by the trade name if produced by another company. Can’t have its characteristic appearance and shape so generics look different—confusing the customer Generic and trade have the same chemical compound but inactive ingredients may be different (binders, fillers, dyes, preservatives) Pro’s- lower cost, more reimbursement, lower co-pay Con’s- Clients don’t recognize appearance- get anxious. May have a reaction to inactive ingredient Nurses must teach and dispel myths Drug Oriented Society “all you have to do is take a pill” Not as receptive to alternate therapy such as diet and lifestyle changes Strong media influence- headache, hemorrhoids-heartburn-Viagra Nurse must have broad knowledge of drugs, actions, side effects, food interactions, etc. Take on empty stomach or with food. Drug Interactions ETOH interactions- increases CNS depressant and interacts with Flagyl Diet restrictions with MAO inhibitors, L-dopa to reduce protein Caffeine/tobacco influences Bronchodilators and smoking- need increased dose-quit smoking you can decrease the dose Caffeine and CV drugs- caffeine raises blood pressure and will negate the hypertension medication. MAOI’s Discovered with INH-isoniazid (tuberculosis drug) Increases serotonin and dopamine by inhibiting the MAO enzyme Nardil-phenelzine (generic name) Contraindications: Pts. With cardiovascular disease, under 16 years, pregnancy and lactation, should not abruptly discontinue drug. MAOI’s- Contraindicated Drugs and Food Drugs Levodopa Insulin Any antidepressant Benadryl Diuretics Adrenergic drugs Foods: No tryamine tryptophan Nothing fermented or aged (beer, wine, cheese, sour cream, yogurt) No liver, figs, raisins, bananas, pineapple No processed food (corned beef, salami, pepperoni, hot dogs) MAOI Interactions Hypertensive crisis- severe headache- palpitation, sweating, chest pain, possible intracranial hemorrhage, and even death Assessment Allergies: cross-allergies are common Iodine based dyes/solutions and seafood Eggs and flu/measles vaccine Rash, itching, hives, laryngeal edema, CV collapse-shock Side effects: N&V, diarrhea, drowsiness Toxic effects: anemia, leukopenia, nephrotoxic Idiosyncratic reaction: unexpected abnormal reaction as dimetapp and hyper child and barbiturate and hyped elderly person Avoid leading questions and questions that put the client on the defensive Open-ended questions best-----only close ended in emergency Other meds taking OTC’s like ASA and Hep Using one or two drug stores increases interactions Liver or kidney disorders Decreased vision Knowledge deficit Is the med effective- verifying with BP’s, temps, etc. How does client cope with adverse reactions and interactions Over the Counter Medicines AKA non-prescription and/or non legend drugs Became legal classification with 1951 Durham-Humphrey amendment All OTC’s required review by FDA in 1972 to ensure effectiveness as well as safety: looks at advertising and labeling of the OTC’s. Some formally legend drugs are deemed safe for self medication and changed to OTC- ibuprofen OTC- categories Analgesics Cold, Cough, and Allergy meds Antacids Laxatives GI Preps Sleeping aids Vitamins OTC Read the label Compare cost Consult pharmacist- buy prescriptions and non-prescriptions at the same drug store Limited effectiveness Problem will resolve itself with non-pharmacological measures Cold Medicine Histamines released from the mast cells are responsible for signs of cold (mast cells are in the nose) Last 7-10 days Antihistamines decrease histamine activity by blocking the receptor sites for histamine activation Dry secretions Eliminated slowly from the body- half life of 30-36 hours Time release sound good but amounts released at any one time may be too little to be effective Common side effect: drowsiness- give at HS Avoid use with ETOH or CNS suppressants Hyperactivity seen sometimes with children Dizziness, hypotension, sedation, and confusion in the elderly may lead to falls Urinary retention!!! Pseudophed (remember state boards) Physician consultation is required if client has a history of hypertension, CV disease, hyperthyroidism, asthma, narrow-angle glaucoma, or BPH Decongestants Congestion caused by dilated blood vessels and fluid collection in the nasal mucosa Decongestants act through vasoconstriction on the nasal blood vessels May be oral or topical spray Rebound reaction with vasodilation stuffiness Limit to 3 days use Oral meds cause: jitteriness, increased BP, hyperglycemia, cardiac irregularities- Dr Consult as with Cold medicines Cough Preparations Cough is due to postnasal drainage into the respiratory tract- cough is dry and nonproductive Causes lack of rest Use increased humidity and fluids work as well Cough suppressant work by inhibiting the cough reflex in the medulla Avoid as much as possible with a productive cough since secretion needs t be coughed up and out Limit use to 7 days and then see doctor Some have codeine Dextromethorphan is a narcotic derivative without addictive potential and is found in Robitussin and Benylin Expectorants Supposed to loosen, liquefy secretions and facilitate their removal from the lower respiratory tract Humidity and fluids can do the same things May cause GI upset and N/V Terpin hydrate elixir has high alcohol content and may be abused. Guaifenesin-Mucinex-Antituss-Robitussin Sore Throat Must distinguish strep from viral first Salt-water gargles, non-medicine hard candy, humidity, and fluids will be more effective Tylenol or ASA for pain Multisystem Cold Preps Read the label carefully for ingredients and don’t overdose- watch acetaminophen Analgesics and Antipyretics ASA and acetaminophen are the most common analgesics for mild to moderate pain Both have antipyretic properties also. ASA is also an anti-inflammatory agent unlike acetaminophen Acetaminophen is preferred for children sin ASA use with viral infections in children is linked to Reye’s syndrome and Tylenol comes in liquid form ASA GI upset Use enteric coated ASA- Ascriptin or Ecotrin Enteric coated bypasses the stomach and dissolves in the alkaline environment of the small intestines (causes delayed absorption) Enteric coated should not be taken with antacid since the antacid will cause it to break down in the stomach Buffered ASA-Bufferin Take with a full glass f water or food to minimize irritation Gastric ulcers- bleeding in stool- anemia Hazard with children Signs of overdose: 1st symptoms is increased respirations- Tachypnea Ringing in the ears (tinnitus) Dizziness Confusion Headache Flushing Convulsions Hallucinations Don’t give with Heparin, Lovenox, or Warfarin. It has anti-platlet activity- take with chest pain Acetaminophen-Tylenol-Tempra High doses cause liver damage Watch infant, children dosages and don’t mix Watch combination drugs- read labels Ibuprofen Non-steroidal anti-inflammatory analgesic 200 mg every 4-6 hours Prescription strength is 300-800 mg 3-4 times a day If use with ASA it reduces anti-inflammatory response and causes GI irritation Inhibits prostaglandin production which causes dysmenorrhea. Dr. consult if have chronic disease like diabetes, ulcers, or are on anticoagulants More expensive than aspirin Laxatives Most misused and abused of all the OTC medicines Try non-pharmacological measures first Bulk forming- Metamucil Saline laxatives- MOM and Epsom salts Stimulant laxatives- Dulcolax, Ex-lax, Senokot Lubricants Mineral Oil- decrease in fat-soluble vitamins Stool Softeners-Colace-Surfak Antacids Don’t self-medicate if acute gastric or chest pain- SOB- sweating Hematemesis- vomiting blood, don’t use antacid Distress lasting longer than 2 weeks- don’t use Occult bleeding- do not use Liquid more effective and less costly in liquid form*** Sodium Bicarbonate- baking soda- large doses may result in alkalosis- high in sodium- not for regular use Calcium carbonate- neutralizes stomach acids but causes rebound (Tums) Magnesium- diarrhea Aluminum- constipation Riopan and Aludrox are low sodium antacids Nurse’s Role in OTC’s Assessment Teaching before moment of discharge Explanation of how they affect legend drugs Side effects/Toxic effects Evaluate compliance Definitions Pharmacology- the study of all aspects of drugs and their effects on living systems Pharmacodynamics- studies the biochemical and physiologic action/effect of a drug (drug action, adverse effects and allergy) Allergic reactions: rash, itching, hives, laryngeal edema, anaphylactic shock Side effects/Adverse effects: N/V/D, drowsiness, fatigue, dizziness Toxic effects: leukopenia, Anemia, Nephrotoxic- dose will be decreased or discontinued Idiosyncratic Reactions- unexpected abnormal reaction
