penicillins
Ch 37
Penicillin’s are called B-lactam antibiotics because they have the ring
Antibiotic that there is most likely to have a anaphalatic reaction to (along with sulfonamides)
Adverse effects of penicillin’s-Allergic reactions to penicillin occur in 0.7% to 4% of treatment courses. The most common reactions are uticaria(itching), pruritus(itching), and angioedema(red spots). Anaphylactic reactions are much less common, occurring in 0.004% to 0.015% of patients. Patients who are allergic to penicillins have a fourfold to sixfold increased risk of allergy to other B-lactam antibiotics. The incidence of cross-reactivity between cephalosporin’s and penicillins is reported between 1% and 18%.These allergies generally occur not on the first time you took the drug but on the subsequent times because you have to build up antibodies from the first time and then the body reacts to them the next time.
cephalosporins
Ch 37
12. Cephalosporins are the largest group of antibiotics. There are over 30 different ones used today. There are four generations of cephalosporins. Depending on the generation, these drugs may be active against gram-positive, gram-negative, or anaerobic bacteria. In general, the level of gram-negative coverage increases with each successive generation. So first generation antibiotics are most active against gram positive bacteria same as the penicillins, but as you go one to 2nd 3rd and 4th generation you have more levels of gram negative, some become more broad spectrum they effect more kinds of bacteria.

Ch 18
SLOW
decrese blood pressure and pulse
Beta blockers include: propranolol (Inderal),
side effects: hypotension, bradycardia, fatigue, depression, hypoglycemia.
SympatheticBeta 1 receptors are blocked. decreases HR resulting in decreased myocardial oxygen demand and increased oxygen delivery to the heart.
NOTE: Side affects include constipation, H/A, lightheadedness, hypotension, dizziness,
After an MI, a high level of circulating catecholamines are irritating the heart causing an imbalance in supply and demand ration and even leading to life threatening dysrhythmias. Beta blockers block harmful effect of catecholamines improving survival after MI

benadryl, alegra, claritin, zyrtec- newer drugs are less sedative
sulfonamides
Ch 37
They were one of the first groups of druds used as antibiotics.
Sulfonabides do not actually destroy bacteria but inhibit heir growth. For this reason they are considered bacteriostatic antibiotics. They prevent bacterial synthesis of folic acid.
592 For sulfonamides, inform the patient to take the antibiotic with plenty of fluids (2000 to 3000 mL/24 hr) to prevent drug-related crystalluria or precipitation in the kidneys, and to take these drugs with food. For tetracycline’s, the patient should be advised to avoid expo-sure to tanning beds and direct sunlight or to use sunscreen and/or wear protective clothing because of drug-related photo-sensitivity. How do you know if an antibiotic is effective or not? Because normally occurring bacteria are killed during antibiotic therapy, super infections may arise during treatment. These may be manifested by the following signs and symptoms: fever, perinial itching, oral lesions, vaginal irritation and discharge, cough, and lethargy. How do you tell if an antibiotic is effective or not? WBC count
antacids
Ch 51
Antacids-calcium based, not prescribed real often because too much calcium can cause kidney stones. Sodium bicarbonate
Antacids work primarily by neutralizing gastric acidity. They do nothing to prevent the overproduction of acid but instead help to neutralize ac id secretions.
The primary drug effect of antacids is the reduction of symptoms associated with various acid-related disorders, such as pain and reflux.
Both the aluminum- and calcium-containing formulations can result in constipation. Calcium products can also cause kidney stones.
The problem with sodium bicarbonate- Use of sodium bicarbonate may lead to metabolic alkalosis if the drug is abused or used over the long term. Alkalosis is manifested by irritability, muscle twitching, numbness and tingling, cyanosis, slow and shallow respirations, headache, thirst, and nausea. To much sodium if you have heart problems can lead to congestive heart failure.
vancomycin
Ch 38
Vancomycin- is the antibiotic of choice for the treatment of MRSA infection and infections caused by many other gram-positive bacteria. It is not active against gram-negative bacteria, fungi, or yeast. Indicated for the treatment of pseudomembranous colitis (can be caused by drugs because they can kill off the normal flora) and for the treatment of staphylococcal enterocolitis.
Adverse effect of vancomycins that is bothersome by usually not harmful is known as red man syndrome. This involves flushing and or itching of the head, face, neck and upper trunk area. Counteract by giving antihistamines (Benadryl).

Ch 37
The name for a broad, major class of antibiotics that includes four subclasses: penicillins, cephalosporins, carbapenems, and monobactams.
B-Lactam Antibiotics-named because of the B-lactam ring that is part of their chemical structure. Commonly used drugs. Bacterial strains produce the enzyme B-lactamase, provides a mechanism for bacterial resistance to these antibiotics. B-lactam is the structure of the antibiotic, B-lactamase is the enzyme that is produced by the bacterial that breaks down the B-lactam ring, if the ring is broken the antibiotic is no longer effective

Stimulant-laxative- most likely to become dependent on, most abused, senna (Senokot)
aminoglycocide
Ch 38
Aminoglycosides are any drugs with –micin on the end of the name. main one is gentamicin. With above normal troughs in -Aminoglycosides you are at greater risk for both ototoxicity (toxicity to the ear) and nephrotoxicity (toxicity to the kidneys). Ototoxicity often manifests as some degree of temporary or permanent hearing loss. Nephrotoxicity manifests in varying degrees of reduced renal function.
Mechanism of action and drug effects of Aminoglycosides- often AGs are used in combination with other antibiotics such as beta-lactams or vancomycin in the treatment of various infections because the combined effect of the two antibiotics is greater than that of either drug alone. This is known as a synergistic effect.

Describe pharmacologic and nonpharmacologic approaches for the management and treatment of acute and chronic pain
Ch 10
Pain management strategies should include an emphasis on the type of pain and it rating as well as pain quality, duration, precipitating factors, and interventions tha help the pain.
Nonpharmacologic measures for pain management should always be used, either as a beginning mode of treatment or as an adjuvant to pharmacologic theraapy and include relaxation therapy, guided imagery, music distraction, exercise, transcutaneous electrical stimulation, and massage.
General principals of pain management include: 1) management of mild to moderate pain often begins with the use of nonnarcotic drugs such as acetaminophen, tramadoln and NSAIDs. 2) moderate to sever pain is generally not managed with nonnarcotics but is usually treated with narcotis. 3) drug selection for treatment of moderate to severe pain should be based on variables such as the characteristics of the individual patient, cultural influences, the disease process, and the use of other therapies(homeopathic, folk, herbal)
Discuss the use of nonopioids, nonsteroidal antiinflammatory drugs (NSAIDs), and opioids (opioid agonists and partial opioid agonists and antagonists) in the management of acute and chronic pain.
Ch 10
Nonopiod analgesics-analgesics that are not classified as opiods, most widely used is acetaminophen, used to manage pain especially pain associated with inflammatory conditions. all drugs in the NSAID class-
NSAIDs- a large, chemically diverse group of drugs that are analgesics and also possess antiinflammatory and antipyretic activity but are not steroids.

Opiods-synthetic narcotic drugs that bind to opiate receptors to relieve pain but are not themselves derived from the opium plant. agonist binds to an opioid pain receptor in the brain and causes analgesic response- the reduction of pain sensation. partial agonist-binds to a pain receptor but causes a weaker neurologic response that a full agonist. antagonist binds to a pain receptor but does not reduce pain signals, it competes with and reverses the effects of agonist and partial agonist drugs at the receptor sites
Identify the various drugs that are classified within the nonnarcotic and narcotic drug groups. (NSAIDs are discussed in Chapter 44.)
Ch 10
Narcotics are drugs that produce insensibiliy or stupor, the term is applied most commonly to the opoid analgesics.
Opiate analgesic's are natural narcotic drugs
Opiod analgesic's are synthetic narcotic drugs
Nonopoiod analgesics are nonnarcotis such as all drugs in the NSAID class, which includes aspirin,acetaminophen, etc.
Tramadon is NOT currently classified as a controlled substance.
Discuss the difference between opioid agonist, agonist-antagonist, and antagonist drugs and their specific use in the management of acute and chronic pain.
Ch 10
opiod agonist-binds to an opioid pain receptor in the brain and causes an analgesic respones-reduction of pain sensation.
opiod agonist-antagonist- binds to a pain receptor but causes a weaker neurologic respones tha a full agonist(aka partial agonist)
An antagonist binds to a pain receptor but does not reduce pain signals, also functions as a competitive antagonist because it competes with and reverses the effects of agonist and partial agonist drugs at the receptor sites.
OPIATE ANTAGONIST- used for complete or partial reversal of opiod-induced respiratory depression.
NALOXONE (narcan)
NALTREXONE (rivia)
Compare the mechanisms of action, drug effects, indications, adverse effects, cautions, contraindications, drug-drug and drug-food interactions, dosages, and routes of administration for narcotic drugs (agonist and partial agonist-antagonist narcotics).
