Muscle contraction is terminated when the amount of free cytoplasmic Ca2 is reduced, by either pumping to the outside of the cell or by returning the Ca2 to storage in the sarcoplasmic reticulum. These are called polyclonal antibodies because they contain a wide mixture of different antibodies. People who lack this enzyme, sometimes called "poor metabolizers," may have up to 50% higher serum levels of haloperidol and other drugs than Caucasians. If a basal dose is not given continuously, assess that pain relief is adequate and contact the provider if pain remains present. Dehydration may also lead to or worsen other conditions such as electrolyte imbalance, delirium, and susceptibility to infections. In addition to childhood, epilepsy manifests with higher frequency during pregnancy and in older adults. Long-term use of sleep medications is likely to worsen insomnia, and many of these medications cause physical or psychological dependence. Rizatriptan (Maxalt): Approved in 1998, rizatriptan is absorbed more quickly than sumatriptan, with an onset of 60 to 90 minutes. Specific (Adaptive) Body Defenses Humoral Immune Response Cell-Mediated Immune Response the human body is under continuous attack from a host of foreign invaders, including viruses, bacteria, fungi, and even single-celled animals. In regions where the incidence of isoniazid resistance is 4% or higher, ethambutol (Myambutol) or streptomycin is included as part of the initial therapeutic regimen. Iron therapy is initiated to alleviate symptoms of anemia caused by blood loss or dietary deficiency. A major Drugs Similar to Risperidone (Risperdal) Other drugs classified as atypical antipsychotics include asenapine, clozapine, iloperidone, lurasidone, olanzapine, paliperidone, quetiapine, and ziprasidone. The thickened membranes can partially occlude the airway and cause difficulty swallowing or a feeling of choking. The nurse will teach the client to avoid taking the tetracycline concurrently with. Mechanism of Action: Morphine occupies mu and kappa receptor sites in the brain and dorsal horn of the spinal cord that alter the release of afferent neurotransmitters. Drugs Similar to Ampicillin (Principen) the only other aminopenicillin is amoxicillin. Because warfarin increases bleeding time, this could result in prolonged bleeding in a patient. Like other salicylates, salsalate produces its effects by inhibiting prostaglandin synthesis. Hypotension is the most common adverse effect, and the risk is increased when the patient is receiving other drugs that lower blood pressure such as diuretics and beta blockers. This chapter examines the penicillins, cephalosporins, and other antibiotic agents that kill bacteria by disrupting their cell walls. Nefazodone acts by blocking serotonin receptors and inhibiting serotonin reuptake. Abrupt discontinuation following prolonged therapy may cause high fever, seizures, severe rebound muscle spasticity, and hallucinations. It is estimated that the antivirals are 70% to 90% effective at preventing influenza A infections. Methazolamide is only approved for reducing intraocular pressure in patients with open-angle glaucoma. Once budding occurs, the immune system recognizes that the cell is infected and kills the T4 lymphocyte. Acute opioid intoxication is a medical emergency, with respiratory depression being the most serious medical challenge. Because of the cost and the lack of symptoms for lipid disorders, nurses may face challenges persuading patients of the value of antihyperlipidemic drug therapy. Gentamicin is bacteriocidal in that it causes premature termination of the growing polypeptide chain. A detailed discussion of coagulation and clot formation is included in Chapter 41. The drug has similar indications, contraindications, and adverse effects to alteplase but has greater fibrin specificity and a longer halflife.
Plasmodium vivax, the most common malarial species, occurs predominantly in India, Pakistan, and Central America. Medication has been found to be effective for girls as well as boys, but the traditional stimulants such as methylphenidate and amphetamine were found to cause increased premenstrual stimulating effects. Epilepsy, however, is a diverse disease that includes nearly 20 different seizure disorders, only some of which involve convulsions. The specific symptoms depend on the nature of the discharge: the location of the abnormal focus in the brain and the extent of the discharge. If the antigen is present, the individual is said to be Rh positive (Rh) and if it is missing, Rh negative (Rh); 85% of individuals living in North America are Rh positive. During the first year of pharmacotherapy, skin lesions may actually worsen because of activation of the cell-mediated immune response. The drug is not very effective as monotherapy, and tolerance develops to its actions with continued use. To understand how medications act on the heart and to predict the consequences of pharmacotherapy, it is essential to have a comprehensive knowledge of normal cardiac physiology. Sam admits to drinking alcohol almost every day and smoking at least one pack of cigarettes per day. Ammonium chloride and other acidifying agents decrease the renal elimination of aspirin, resulting in salicylate toxicity. Dizziness and fainting are common because the brain is not receiving enough oxygen to function properly. Immunization: preexposure and postexposure: Prevention of rabies may be accomplished through vaccination. The negative symptoms, however, often prevent a patient with schizophrenia from living independently, holding down a job, and enjoying life. Slow, shuffling gait, short steps Cholinergic neuron Acetylcholine Benztropine 2 Drug therapy tends to help with symptoms Dopaminergic agents: Precursors to dopamine. Of the topical anesthetics, tetracaine is the most likely to cause skin sensitivity, including rash, erythema, pruritus, burning, and edema. Whenever possible, parenteral injections of other drugs should be avoided during alteplase therapy to avoid an increased risk of bleeding at the injection site. Practice parameter: Pharmacologic treatment of spasticity in children and adolescents with cerebral palsy. Long-acting beta agonists include arformoterol, formoterol, indacaterol, salmeterol, and terbutaline. Do not swallow unless instructed to do so by the provider and do not rinse the mouth with water afterward. Hypersensitivity is observed in 10% to 15% of patients and may begin with a rapid onset of high fever, lethargy, and joint pain. Herbal/Food: Food (especially dairy products), coffee, and tea will inhibit iron absorption. Patients who get migraines appear to have blood vessels that overreact to various triggers. If the drug is bound to plasma proteins, however, it will be too large and will continue circulating in the blood. Like other drugs in this class, however, the development of hyperkalemia is a potentially serious adverse effect. Signs of fluid overload include tachycardia, peripheral edema, distended neck veins, dyspnea, or cough. Reliability and validity of face, legs, activity, cry, consolability behavioral tool in assessing acute pain in critically ill patients. The cell-mediated immune system is also important in producing immunity, but its cellular responses are less readily measured. Patients often wait until these symptoms occur more frequently or become acute before seeking medical intervention. It interferes with plans that she and her husband had made to travel after she retired.
Analgesic treatment of neuropathic pain is often unsuccessful or high doses may be required. Patients with active infections should be treated with antiinfectives prior to cyclosporine therapy. Telithromycin carries a black box warning that it should not be used in patients with myasthenia gravis because fatal respiratory depression may occur. Frail elderly and those with a comorbid condition receive more aggressive pharmacotherapy. Katherine figured that because the potassium was only a "supplement," she would be able to wait until her neighbor returned to get the medication refilled. Mature cyst Immature cyst Invasive infection through the bloodstream, infecting sites such as the liver, brain, and lungs. Sodium stibogluconate (Pentostam): Sodium stibogluconate is the traditional drug of choice for leishmaniasis; however, decades of use have led to near-total resistance in certain strains of Leishmania. The student should refer to Chapter 20 for a detailed discussion of the basic pharmacology of this drug class. To avoid unpleasant symptoms, and to ensure that depression does not quickly return, these drugs are usually withdrawn gradually. Prototype features for beta-adrenergic antagonists can be found for propranolol (Inderal) and metoprolol (Lopressor) in Chapter 20, atenolol (Tenormin) in Chapter 38, and timolol (Betimol, Istalol, Timoptic) in Chapter 77. Pentazocine causes less nausea, vomiting, and respiratory depression than morphine. Patients with anxiety disorders, insomnia, or panic attacks should not be administered caffeine because it may worsen these conditions. Sulfadoxine-pyrimethamine (Fansidar) is used exclusively for treating malaria and is discussed in Chapter 56. Black Box Warnings: Adverse effects from parenteral gentamicin may be severe and include the following: Neurotoxicity may manifest as ototoxicity and produce a loss of hearing or balance, which may become permanent with continued use. Regular, long-term aspirin use has been determined to reduce the risk of colorectal cancer (Rothwell et al. The tetracycline antibiotics used for malaria prophylaxis and treatment are presented in Chapter 51. Tolerance rapidly develops to the actions of desmopressin, although this is usually not a problem when the drug is used to treat hemorrhage because only one to two doses are needed. Decreased libido and temporary sterility in males are other potential adverse effects. Herbal/Food: the extended release form of the drug should be taken on an empty stomach. Fifth-generation cephalosporins are broad-spectrum drugs with extended gram-positive effectiveness. These patients require a dosage adjustment or a change to a different antidepressant. The two drugs have synergistic antimalarial activity and the combination results in less protozoan resistance than when either drug is used as monotherapy. Behavioral problems such as hostility, emotional lability, impaired cognition, aggressiveness, and hyperkinesia have been reported in the pediatric population ages 3 to 12. In most body fluids, osmolality, 567 three solutes determine the osmolality: sodium, glucose, and osmosis, 568 urea. Single-dose or short-course therapy is often preferred for patient convenience and to maximize adherence. Among the topical agents, all have equal effectiveness and similar adverse effects. Lifespan and Diversity Considerations: Keep toileting facilities nearby for the older adult or assist the patient to the bathroom on a regular schedule to avoid incontinence. These agents also depress cardiovascular and pulmonary function, placing the patient at risk for laryngospasm or respiratory arrest. Implications of the changing face of Clostridium difficile disease for health care practitioners.
Respiratory depression may be delayed; thus the patient should be monitored for some time after surgery. Primary metabolism Primary excretion Onset of action Duration of action Adverse Effects: Clopidogrel has approximately the same tolerability as aspirin and adverse effects are rarely severe enough to cause discontinuation of therapy. Mechanism of Action: During the hepatic conversion of ammonium chloride to urea, Cl and H are formed. Blocking potassium, sodium, or calcium ion channels is a pharmacologic strategy used to terminate or prevent dysrhythmias. Proper timing of chamber contractions is made possible by the cardiac conduction system, a branching network of specialized cardiac muscle cells that sends a synchronized, electrical signal across the myocardium. Alpha1-adrenergic antagonists: the alpha1-adrenergic antagonists have several clinical applications, which were presented in Chapter 20. Drug Interactions: Coughing, breath holding, or laryngospasm may occur when used concurrently with nitrous oxide. The domestic cat is an intermediate host to the parasite, and serves as a primary means of transmission to humans. Opioid and nonopioid combinations: It is common practice to use opioid and nonopioid analgesics concurrently in the pharmacotherapy of pain. Immediately report undiminished fever, changes in level of consciousness, febrile seizures, tachycardia, blood pressure over 140/90 or per parameters as ordered, to the health care provider. Benzodiazepines are the first-line drugs for the treatment of certain anxiety disorders and are one of the most widely prescribed drug classes in the United States. The third class of lipids, the steroids, is a diverse group of substances having a common sterol nucleus or ring structure. The emulsion supports rapid microorganism growth; unused portions must be discarded. Drugs in the penicillinase-resistant class share similar actions and properties with penicillin G. Anaphylactic response may include cardiovascular collapse; edema of the mouth, tongue, pharynx, and larynx; confusion; seizures; and hallucinations. Apomorphine is structurally related to morphine, but it does not bind to opioid receptors or cause morphinelike effects (see Chapter 29). Sulfonamides inhibit the enzyme in step 1; the drug trimethoprim inhibits the enzyme in step 3. Heparin-induced thrombocytopenia, a particularly serious form of this disorder, is discussed in Section 41. Katherine was certain that she had enough of her medicine to last through that time. If abruptly discontinued after prolonged use, the patient may experience nightmares, insomnia, tremor, hallucinations, nausea, and vomiting. The general sedative nature of the drug is likely responsible for its ability to relieve the pain associated with muscle spasms. Symptoms include confusion, delirium, convulsions, reduced reflexes, hypotension, and dysrhythmias. Electrolyte imbalances such as hypochloremia, hypomagnesemia, hypokalemia, and hyponatremia may occur. Amiodarone greatly enhances the actions of anticoagulants, thus the dose of warfarin must be cut by as much as half. Lepirudin (Refludan) Classification: Therapeutic: Anticoagulant Pharmacologic: Direct thrombin inhibitor Therapeutic Effects and Uses: Lepirudin is a protein that is nearly identical to hirudin, the natural substance isolated from leeches. Narcotic analgesics are effective at terminating pain from migraines that have proven to be refractory to other therapies. Identify the classes of antibiotics that act by affecting the synthesis of the bacterial cell wall. It is difficult to estimate the frequency of the disease, although it is likely that dysrhythmias are quite common in the population. In recent years, valproic acid (Depakene) has begun to replace lithium as the first-line therapy for bipolar disorder due to its improved safety profile. Neurotransmitters such as serotonin, norepinephrine, and endogenous opioids (endorphins and enkephalins) inhibit pain transmission. Beta blockers are also contraindicated in cardiogenic shock and overt cardiac failure. Some drugs do not kill pathogens but instead slow their growth, allowing natural body defenses to eliminate the microorganisms.
Before teaching the client about this drug, the nurse will discuss the strategy for drug dosage with the health care provider because of which recommended routine for beta-adrenergic blockers in heart failure Significantly lower dosages are used first and gradually increased to a target dose. These agents can create or worsen dysrhythmias, especially during the first few doses. The protozoan Plasmodium, for example, reproduces in the gut of a mosquito and is transmitted to humans during a mosquito bite, causing malaria. Chloroquine is very effective in treating acute symptoms of the erythrocytic stage, but has no activity against dormant P. Penicillin G is available as a benzathine, potassium, or a procaine salt; each has slightly different pharmacokinetics. Patients with a history of epilepsy have an increased risk for seizures when taking sumatriptan. Pharmacotherapy of systemic mycoses is often continued for many months to ensure the fungus is eliminated. Also instruct patients on transdermal patches to always remove the old patch, cleanse the skin underneath gently, and to rotate sites before applying a new patch. Neurologic symptoms rapidly develop, including nuchal rigidity, headache, photophobia, and seizures. One important aspect of prevention is getting immunizations to protect against diseases such as influenza, tetanus, polio, measles, and hepatitis B (see Chapter 46). Compare the types of drugs used for preventing migraines to those for terminating migraines. When used concurrently with erythromycin, the serum levels and toxicities of alfentanil, carbamazepine, cyclosporine, fentanyl, theophylline, and methadone may increase. Hypercoagulation may occur with concurrent use of estrogens and oral contraceptives. Herbal/Food: Herbal supplements that may affect coagulation such as ginger, garlic, green tea, feverfew, or ginkgo should be avoided because they may increase the risk of bleeding. The study concluded that advancing age is a risk factor for postoperative cognitive dysfunction, and may have an impact on surgical mortality in the first postoperative year. Over decades of use, many bacterial strains have developed resistance to the cephalosporins. Precautions and other adverse effects are similar to the other cholinesterase inhibitors. Tramadol should be avoided during pregnancy and lactation because its chronic use can cause physical dependence and postpartum withdrawal symptoms in the newborn. The student will encounter the term phenothiazine in other chapters because several drug classes produce "phenothiazine-like" adverse effects. An episode of narcolepsy may last from a few seconds to about 30 minutes and the disorder may start anytime between ages 5 and 50. Monobactams have little or no activity against gram-positive bacteria or anaerobes. Nefazodone: Chemically similar to trazodone, nefazodone causes minimal cardiovascular effects, fewer anticholinergic effects, less sedation, and less sexual dysfunction than some of the other antidepressants. Patients taking drugs for insomnia or anxiety should limit their intake of caffeine. Mechanism of Action: Upon reaching vascular smooth muscle, nitroglycerin forms nitric oxide, which triggers a cascade resulting in the release of calcium ions in smooth muscle. A topical form of tacrolimus (Protopic) is indicated for the short-term treatment of eczema and atopic dermatitis; the topical drug contains a black box warning of possible lymphoma and skin cancer. Mechanically ventilated patients may receive lorazepam infusions to manage excessive anxiety and agitation that are characteristic of being connected to this device.

Memory: After an antigen interaction occurs, cells of the adaptive immune system remember the immune response. Other adverse effects from the nondihydropyridines include constipation, flushed skin, headache, dizziness, edema of the ankles and feet, and lightheadedness. It is the only tetracycline that can cause reversible vestibular toxicity, resulting in dizziness, vertigo, and weakness that can limit therapy. The human body is remarkably resistant to infection by these organisms and patients with healthy immune defenses experience few serious fungal diseases. The adjuvant analgesic activity of the bisphosphonates such as pamidronate (Aredia) and zolendronate (Reclast, Zometa) has been well established. For all indications, therapy with carbamazepine must be monitored carefully and the dosage adjusted based on clinical outcomes and drug serum levels. Fewer teachers identified steps to manage asthma symptoms, with most identifying "contacting the nurse" as the usual step taken. Assess for nonverbal signs of pain such as restlessness or grimacing as the patient regains consciousness. He was stabilized with lithium for the manic periods and is also taking valproic acid. Aripiprazole (Abilify) is the only approved drug in this class at the current time. Its use in the pharmacotherapy of acetaminophen toxicity is presented in Chapter 44. Evidence: Thousands of studies have been conducted on the polyphenols contained in this supplement. Use of other ototoxic drugs such as the aminoglycoside antibiotics should be avoided during loop diuretic therapy due to the potential for additive hearing impairment. As expected, phagocytes are found in large numbers in the blood, in lymphatic tissues, and in locations where pathogens have the highest likelihood of entering. For what adverse effects should you monitor in patients receiving this drug therapy Nurse led interventions to improve control of blood pressure in people with hypertension: Systematic review and meta-analysis. Prevention of cytokine release syndrome may be accomplished by administering corticosteroids, antihistamines, and acetaminophen 1 to 4 hours prior to muromonab therapy. Children have symptoms similar to those of adults but present with a higher incidence of seizures and mental status changes (National Multiple Sclerosis Society, n. Lifespan and Diversity Considerations: Monitor for bleeding more frequently in the older adult who is at higher risk for injury and bleeding. These needs are transmitted to pluripotent stem cells by regulatory substances that include various hormones and proteins. It is usually given in combination with the antiviral ribavirin over a period of 24 to 48 weeks. Therapy is always begun with a low dose, which is gradually increased until the desired therapeutic effect is attained. Patients who demonstrated severe hypersensitivity to the first dose should not receive subsequent doses. A few nonbenzodiazepine drugs have antianxiety properties but their primary use is for indications other than anxiety. Blockade of calcium channels has a number of effects on the heart, most of which are similar to those of beta blockers. Beta blockers are usually administered concurrently to minimize tachycardia, and diuretics to prevent fluid retention. Virtually all are resistant to high levels of ampicillin, which is the conventional treatment for enterococci infections. The effectiveness of the vaccine in producing immunity in adults declines with age. Local injection-site reactions, drowsiness, persistent crying, and fever occur in 3% to 5% of patients receiving the vaccine. The drug is used off-label for many other indications, depending on the sensitivity of the microbe.
Because of the dangerous adverse effects of long-term therapy, systemic corticosteroids are generally reserved for short-term management of acute asthma exacerbations. The two drugs are not related chemically, but both have short durations and can induce anesthesia rapidly. Increased serum levels and possible hypotension may occur if administered concurrently with epinephrine. Contraindications/Precautions: Azathioprine should be used with extreme caution in patients with preexisting hematologic disease or hepatic impairment. The immune response to dead or attenuated organisms in a rabies vaccine takes approximately 2 weeks to develop, which is well within the incubation period of rabies. Antacids and vitamin supplements containing calcium or aluminum, iron or zinc sulfate, and sucralfate decrease the absorption of ciprofloxacin, thus causing decreased effectiveness of the antibiotic. It is recommended that the pretreatment blood pressure be progressively reduced by 20% to 25%, over 30 to 60 minutes. The most common coagulation disorder is a deficiency of platelets, or thrombocytopenia, which occurs when platelet counts fall below 150,000 mm3. The treatment plan was to admit her into the hospital for anticoagulant therapy and pain control. The American Heart Association recommends that all children ages 3 and older have their blood pressure taken yearly. Lovastatin is a prodrug with no intrinsic activity of its own, but the liver converts it to several active metabolites. Aspirin allergy symptoms include rash, urticaria, dyspnea, wheezing, rhinorrhea, and cough. Jenner used the cowpox virus, a benign pathogen in humans, because he predicted that exposure to that virus would provide immunity to smallpox, which was one of the most dreaded human diseases of that era. Cardioselective beta blockers decrease heart rate, myocardial contractility, and cardiac conduction velocity. Antibiotics that inhibit protein synthesis do so by affecting subunits of the bacterial ribosome. For example, it may increase digoxin levels by 20% as well as increase levels of norethindrone and ethinyl estradiol (oral contraceptives). In the broadest definition, anxiolytics include drugs from a large number of different pharmacologic classes. Assessment throughout administration: Continue frequent assessments for therapeutic effects. If the patient or family so chooses, notify the provider so that appropriate alternatives may be considered. Thaw foods in refrigerator or microwave and consume foods within 48 hours of purchase because tyramine content may increase with aging. Hydrocodone is an effective antitussive and is combined with decongestants or antihistamines for severe cold and flu symptoms. Seizures that result from acute, temporary conditions generally do not reoccur once the underlying medical condition has been successfully treated. Treatment of Overdose: Overdose can cause vomiting, tremor, and drowsiness, but fatalities have not been reported. If serum thiocyanate exceeds 12 mg/dL, the nitroprusside infusion should be discontinued. Compatibility of any medication should be checked prior to initiating infusions in the same line. Excess potassium may also accumulate when renal excretion is diminished due to kidney pathology. The main route of metabolism of isoniazid is through enzymatic acetylation in the liver. Phagocytes have proteins on their surface that allow them to recognize cells and cellular components that are "non-self. Unlike transplant recipients who may receive immunosuppressants indefinitely, patients with autoimmune disease are usually given these drugs for brief periods in high doses to control relapses. Drugs Similar to Metronidazole (Flagyl) Other selected antiprotozoan drugs for amebiasis, giardiasis, or cryptosporidiosis include furazolidone, iodoquinol, nitazoxanide, paromomycin, and tinidazole. Type A is the most common, causes the most severe symptoms, and has been responsible for serious pandemics throughout history. The disease is progressive, with the expression of full symptoms developing over many years.
A second approved indication for clonidine (Duraclon) is intractable pain in patients with cancer that is not relieved by opiates. Because hypotension may occur, frequent blood pressure measurements should be taken when using this therapy. All potassium supplements and the use of salt substitutes containing potassium should be discontinued. The second primary thromboembolic disorder is pulmonary embolism, which occurs when a venous clot dislodges, migrates to the pulmonary vessels, and blocks arterial circulation to the lungs. Because enterococci are hardy organisms, they can survive for prolonged periods on environmental surfaces, and health care workers using poor infection control techniques can easily spread them. Because it is a cholinergic agonist, donepezil will decrease the effects of anticholinergic drugs. Some patients may have visual hallucinations, seeing persons or objects that are not present. Decreased risperidone levels may occur with the use of phenobarbital, rifampin, omeprazole, or carbamazepine. Intranasal sympathomimetics produce few systemic effects because only minimal amounts of these drugs are absorbed in the circulation. Patient and Family Education: Take the dose in the morning because taking it late in the day may cause insomnia. Organisms that produce beta lactamase are resistant to many of the penicillin and cephalosporin antibiotics. Drugs in this class are contraindicated in pericardial tamponade and constrictive pericarditis because the heart is unable to increase cardiac output to maintain blood pressure when the drug causes vasodilation. Because acetazolamide alkalinizes the urine, the renal excretion of many drugs may be decreased, including tricyclic antidepressants, procainamide, amphetamines, ephedrine, and quinidine. Black Box Warning: Although rare, hepatotoxicity is a serious and sometimes fatal adverse effect; thus, the patient should be monitored carefully for jaundice, fatigue, elevated hepatic enzymes, or loss of appetite. It should not be used in patients with active bleeding or a history of transient ischemic attack or stroke. The drug promotes skeletal muscle relaxation, thus decreasing muscle spasms and increasing joint mobility. The neurotransmitter accumulates in the synaptic cleft and activates more receptors, thus causing an enhanced effect at the synapse. The diet appears to be equally effective for every seizure type, although those with drop attacks (atonic seizures) may be the most rapid responders. A positive family history is present in the majority of people who experience migraines. The echinocandins are better tolerated than amphotericin B and do not exhibit significant nephrotoxicity or hepatotoxicity. His teachers have consistently reported that he is easily distracted and wanders around the classroom even during a lesson. Treatment of Overdose: Isoniazid overdose may be fatal and treatment is mostly symptomatic. Starting drug therapy after allergy symptoms are severe will require several consistent doses before a marked improvement of symptoms is noted. Lifespan and Diversity Considerations: Monitor hepatic and renal function laboratory values and urine output more frequently in the older adult because age-related physiological changes may increase the risk of adverse effects. Class names such as aminoglycosides, fluoroquinolone, and sulfonamides refer to the fundamental chemical structure shared by a group of anti-infectives. In addition, pharmacotherapy is often required to treat common comorbid conditions such as depression, anxiety, or psychosis. Patient and Family Education: Do not abruptly stop taking this drug because dangerously high blood pressure and anxiety could result. Often, the organisms that cause subcutaneous and cutaneous infections are different from those that cause superficial infections, as listed in Table 55. In the very acidic environment of urine, methenamine hippurate is metabolized to formaldehyde, a breakdown product toxic to microorganisms.
