Contraindications: Hypersensitivity to narcotics of the same chemical class, paralytic ileus, acute asthmatic attack, severe respiratory depression, upper urinary tract obstruc- tion, pulmonary edema secondary to chemical respiratory irritant. If nausea and vomiting persist, it may be necessary to administer an antiemetic, eg, droperidol or prochlorperazine. Mechanism of action: Oxytocic action: stimulates contractions of uterine smooth muscle. Contraindications: Hypersensitivity to oxytocin, fetal distress, severe toxemia, total placenta previa, anticipated nonvaginal delivery (invasive cervical cancer), prolapse, active herpes genitalis, unfavorable fetal position, hyperactive uterus, contraindicated vagi- nal delivery, women with four or more previous deliveries. Clinically important drug interactions: Drugs that increase effects/ toxicity of oxytocin: sympathomimetics, vasoconstrictors, cyclo- propane, thiopental. Parameters to monitor • Fetal maturity, presentation, adequacy of pelvis before admin- istration of oxytocin for labor induction. Mechanism of action: Inhibits normal reorganization of micro- tubules required for mitosis, thus inhibiting tumor cell division. Note: This course of treatment should not be repeated unless the neutrophil count is at least 1500 mm3 or platelet count is 100,000/mm3. Contraindications: Contraindicated in patients with hypersensi- tivity to paclitaxel or polyoxyethylated castor oil (excipient), neutrophil count <1500 mm3, pregnancy. Advice to patient: Use two forms of birth control including hor- monal and barrier methods. Adverse reactions • Common: nausea, vomiting, diarrhea, alopecia, myalgia, phlebitis, erythema at site of injection. Clinically important drug interactions • Cisplatin increases the effects/toxicity of paclitaxel. Parameters to monitor • Monitor vital signs frequently, particularly during the 24 hours of infusion. It is recommended that all patients should receive one of the following prior to administration of paclitaxel: diphenhydramine, an H2 blocker, dexamethasone. Infusion should be stopped if patient mani- fests dyspnea, chest pain, hypotension. Paclitaxel is active in breast cancer, ovarian cancer, non-small cell lung cancer, and head and neck cancers. In combina- tion with cisplatin or carboplatin, it is the drug of choice for ovarian cancer. It is also approved for adjuvant chemotherapy for lymph node-positive breast cancer. Mechanism of action: Blocks nicotinic acetylcholine receptors at neuromuscular junction, resulting in skeletal muscle relax- ation and paralysis. Contraindications: Hypersensitivity to pancuronium and chem- ically related drugs. Editorial comments • This drug is listed without details in the Physician’s Desk Ref- erence, 54th edition, 2000.

In summary 25 mg benadryl mastercard allergy and immunology fellowship, this study illustrates that gender and intelligence influence speech patterns at the microscopic level of word-types 25 mg benadryl sale allergy shots hurt. In experimental studies for determining whether or not a drug will facilitate interrogation benadryl 25 mg on-line allergy cure, the fact that intelligence and gender separately affect speech requires consideration benadryl 25mg with mastercard allergy symptoms weather. These investigators explored the effects of a placebo, promazine, secobarbital, and meperidine hydrochloride on a series of objective motor, intellectual, and perceptual activities, as well as on subjective responses. The subjective responses were evaluated 30, 90, 150, and 210 min after the drug was taken. Promazine and secobarbital had an adverse effect on the performance of motor tasks but not on simple intellectual and perceptual tasks. Meperidine hydrochloride in 50 to 100-mg doses did not impair performance in any of these same psychologic functions. Finally, if large enough doses of a drug were given, all subjects tended to respond in the same manner. At intervals, before and after administration of the drugs, the subjects completed a questionnaire designed to measure the "subjective" mood changes induced, and this was supplemented by discussing with the subjects their responses to the drugs. In "normal" and, to a lesser degree, in chronically ill patients, amphetamine surpassed morphine, heroin, pentobarbital, and a placebo in producing euphoria. In the narcotic addicts, however, morphine was reported to produce a more pleasant effect than heroin, amphetamine, or a placebo. The sedation threshold, as measured by the onset of slurred speech, was highest for neurotic introverts and it decreased step-wise for each of the groups in the order given. In other words, the group of introverted neurotics required the largest amount of intravenous sodium amytal (6. Some of the brain-damaged patients, who before receiving the drug had expressed awareness of illness and who had good orientation for place and person, with the drug became disoriented for place and grossly misidentified the examiners and explicitly denied illness. Weinstein claims that these changes with sodium amytal occurred only in the brain-damaged individuals; whereas, in nonbrain-damaged individuals receiving sodium amytal, the subjects talked of illness in terms of a third person, used more "concrete" symbols, selectively misinterpreted questions about illness, and misnamed the examiners in "paraphasic" fashion. Hoch, Cattell, and Pennes (64, 65) administered sodium amytal, pervitin, and mescaline to each of sixteen patients suffering from the pseudo neurotic form of schizophrenia, twenty-four patients with an overt form of schizophrenia with slight. With these drugs, especially with mescaline, they found typical physiologic changes occurring, mainly involving the vegetative nervous system. However, with most patients, some aspects of the drug experience seemed to be a direct continuation of previous personality factors. For instance, a patient who showed obsessive compulsive features before the drug experiment would tend to show the same obsessive structure while intoxicated. The same was true about anxiety attitudes, intellectualizations of conflicts, preoccupations with artistic, philosophical, or other matters. Although Beringer () in his drug studies, using mescaline, did not find any correlation between personality and drug reaction, Stockings (122) found that cyclothymic and schizothymic individuals re- -107- sponded differently. Bensheim (15) thought that the cyclothymic group responded with euphoria and depression to mescaline and the schizothymic group with ecstasy. Guttman and MacClay (59) and Sarwer-Foner (118) also found correlations between personality and drug reactions. It is perhaps of interest here that Russian scientists have also emphasized the differential response of different types of individuals to drugs, specifically chlorpromazine (86). It has been obvious to those who listen to and study people with personality disorders that the verbal behavior of an individual suffering from an emotional disorder is relatively peculiar, both in form and in content. The hysteric and schizophrenic are quite variable in the duration and length of their remarks. There are typical thematic and structural characteristics of the speech habits of patients with these types of psychiatric disorders. Years of intensive research are needed to supply some of this unavailable knowledge. However, it is already acknowledged that individuals with features of hysterical, conversion, or dissociative reactions are likely to be suggestible and to react strongly to all psychopharmacologic agents, including placebos (83, 85). Drugs may tend to reinforce the need to give for individuals burdened with feelings of neurotic shame and guilt, especially if such feelings are enhanced by the interrogator. Drugs may also furnish the needed excuse and relief from personal responsibility for sources who violate internalized values and loyalties in revealing information. The pharmacologic effect of the drug is probably of less decisive influence in facilitating information- getting (although acting as a catalyst) than is the potential readiness of individuals with such per- -108- sonality features to behave in a typical way under certain circumstances. The consideration of drugs as an aid to interrogation presupposes a thorough understanding of the personality characteristics of the informant and of drugs, to predict what might be expected by their use. If so, this propensity is pertinent to our specific interest regarding the use of drugs in affecting the verbal behavior of informants. It is difficult to ascertain to what extent the behavioral alterations that have been noted under various physiologic conditions are mediated by biochemical changes per se, and to what extent they are secondary psychophysiologic reactions to subtle changes in body chemistry. The answer need not occupy us here, except to note that a chemical alteration within the body is probably one important feature of the varying responsivity of the individual. Under such circumstances, the addition of other chemicals complicates the problem of predicting the behavioral outcome. This is particularly true if the new chemical introduced into the body is mild in its effects, or if it is given in a small dosage. Citation of every technical article bearing on this point would be unnecessarily burdensome here. Benedek and Rubenstein (12, 13) have studied the relationship of associative material presented by women during psychoanalysis at various phases of their menstrual cycle, as measured by vaginal smears. These two types of data, verbal material and physiologic changes in the vaginal mucosa, were collected and analyzed independently by the two investigators, one a psychoanalyst and the other an endocrinologist. After a long period of collecting such data, the investigators related verbal productions to the phases of the menstrual cycle. However, because of the importance of the psychophysiologic implications of this classical study, independent validation by other investigators would be desirable. In brief, the investigators found that during the estrogen phase of the menstrual cycle, the women were more extroverted, had more fantasies, dreams, and subjective experiences indicating strivings to be loved and impregnated and had con- -109- flicts about such strivings. During the progesterone phase, the women were more introverted, were more preoccupied with interests in their own body and self. During the premenstrual phase of the cycle, there were increased references to cleaning out, washing out, evacuating, losing something, and the women were more depressed. Studies of the effects of the state of nutrition, especially vitamin deficiency, on human behavior are replete in the medical literature and indicate that neurological and psychiatric disorders may ensue with various vitamin deficiencies, particularly of the B complex. The effects of starvation, voluntary and enforced, in provoking increasing lassitude, apathy, depression, preoccupation with food, flattening of affect, and mood are sufficiently well known and are discussed in another chapter of this study. The more subtle effects of satiation with food and the brief deprivation of food typical of everyday rhythmical eating habits on response patterns to psychologic tests and interviewing procedures have received little careful study, even apart from problems of drug effects.

Precautons Tolerance or dependence may occur with prolonged use; elderly and debilitated patents; hepatc impairment (Appendix 7a); renal impairment; lactaton; overdosage: see chapter 7 buy cheap benadryl 25mg allergy forecast joplin mo. Adverse Efects Nausea cheap benadryl 25mg with mastercard allergy medicine baby, vomitng cheap 25mg benadryl free shipping allergy report austin, constpaton generic 25mg benadryl free shipping allergy medicine for ragweed, drowsiness; respiratory depression and hypotension (large doses); dependence; difculty with micturiton; ureteric or biliary spasm; dry mouth, sweatng, headache, facial fushing, vertgo, bradycardia, tachycardia, palpitatons, hypothermia, hallucinatons, dysphoria, mood changes, miosis, decreased libido or potency, rash, urtcaria, pruritus; convulsions (large doses). Furazolidone Pregnancy Category-C Schedule H Indicatons Giardiasis; cholera; gastrointestnal infectons; protozoal or bacterial diarrhoea and enterits; food poisoning. Precautons Urine colour changes to yellow afer administraton; orthostatc hypotension; hypoglycaemia; pregnancy (Appendix 7c); interactons (Appendix 6a, 6c). Adverse Efects Nausea, vomitng, headache; hypotension; urtcaria; dyspnea; dizziness. Loperamide Pregnancy Category-C Schedule H Indicatons For the control and symptomatc relief of acute nonspecifc diarrhoea and chronic diarrhoea associated with infammatory bowel disease or gastroenterits; for reducing the volume of discharge from ileostomies. Contraindicatons Conditons where inhibiton of peristalsis should be avoided, where abdominal distension develops, or in conditons such as actve ulceratve colits or antbiotc- associated colits. Precautons Liver disease; pregnancy: (Appendix 7c); interactons (Appendix 6c); glaucoma; Crohn’s disease; urinary bladder obstructon. Adverse Efects Abdominal cramps, dizziness, drowsiness and skin reactons including urtcaria; paralytc ileus and abdominal bloatng also reported; constpaton; headache; meteorism; nausea; dry mouth; urinary retenton. Before prescribing laxatves, it is important to be sure that the patent is constpated and that the constpaton is not secondary to an underlying undiagnosed complaint. It is also important that the patent understands that bowel habit can vary considerably in frequency without doing harm. For example, some people consider themselves constpated if they do not have a bowel movement each day. A useful defniton of constpaton is the passage of hard stools less frequently than the patent’s own normal patern and this should be explained to the patent since misconceptons about bowel habits have led to excessive laxatve use which in turn has led to hypokalaemia and an atonic non-functoning colon. Laxatves should generally be avoided except where straining will exacerbate a conditon such as angina or increase the risk of rectal bleeding as in haemorrhoids. Laxatves are of value in drug-induced constpaton, for the expulsion of parasites afer anthelminthic treatment and to clear the alimentary tract before surgery and radiological procedures. Prolonged treat- ment of constpaton is rarely, necessary except occasionally in the elderly. These include bulk-forming laxatves which relieve constpaton by increasing faecal mass and stmulatng peristalsis, stmulant laxatves which increase intestnal motlity and ofen cause abdominal cramp, faecal sofeners which lubricate and sofen impacted faeces and osmotc laxatves which act by retaining fuid in the bowel by osmosis. Bowel cleansing solutons are used before colonic surgery, colonoscopy or radiological examinaton to ensure that the bowel is free of solid contents; they are not a treat- ment for constpaton. Contraindicatons Intestnal obstructon (causes abdominal cramps), acute surgical abdominal conditons, acute infammatory bowel disease, severe dehydraton; faecal impacton, chronic use. Precautons Excessive use of stmulant laxatves can cause diarrhoea and related efects such as hypokalaemia; however, prolonged use may be justfable in some circumstances; don’t give antacid within 1 hour, pregnancy (Appendix 7c), infammatory bowel disease, pre-existng heart disease or bowel disease, allergies, interactons (Appendix 6d). Adverse Efects Tablets- griping; suppositories-local irritaton; faintng, dizziness, soreness in anal region due to suppository leakage; abdominal discomfort, electrolyte imbalance, hypokalaemia. Contraindicatons Galactosemia, intestnal obstructon, patents on low galactose diet. Adverse efects Diarrhoea (dose related), nausea, vomitng, hypokalaemia; dehydraton; hypernatremia; bloatng and abdominal cramps. Dose Oral Adult- 2 to 4 tablets, usually at night; inital dose should be low, then gradually increased. Precautons Avoid prolonged use unless indicated for preventon of faecal impacton; pregnancy (Appendix 7c), lactaton (Appendix 7b); hypersensitvity, undiagnosed abdominal pain, intestnal blockage. Adverse Efects Abdominal discomfort; atonic non- functoning colon and hypokalaemia (with prolonged use or overdosage); red or yellow brown urine, diarrhoea, nausea, vomitng, bloatng. Severely dehydrated patents must be treated initally with intravenous fuids untl they are able to take fuids by mouth. For oral rehydraton it is important to administer the soluton in small amounts at regular intervals as indicated below. Plan A: No dehydraton: Nutritonal advice and increased fuid intake are sufcient (soup, rice, water and yoghurt, or even water). For infants aged under 6 months who have not yet started taking solids, oral rehydraton soluton must be presented before ofering milk. In the case of mixed breast-milk/formula feeding, the contributon of lactaton must be increased. Plan B: Moderate dehydraton: Whatever the child’s age, a 4-h treatment plan is applied to avoid short-term problems. It is recom- mended that parents are shown how to give approximately 75 ml/kg of oral rehydraton soluton with a spoon over a 4-h period and it is suggested that parents should be watched to see how they cope at the beginning of the treatment. A larger amount of soluton can be given if the child contnues to have frequent stools. In case of vomitng, rehydraton must be discontnued for 10 min and then resumed at a slower rate (about one teaspoonful every 2 min). The child’s status must be re-assessed afer 4 h to decide on the most appropriate subsequent treatment. Oral rehydraton soluton should contnue to be ofered once dehydraton has been controlled, for as long as the child contnues to have diarrhoea. Plan C: Severe dehydraton: Hospitalizaton is necessary, but the most urgent priority is to start rehydraton. In hospital (or elsewhere), if the child can drink, oral rehydraton soluton must be given pending, and even during intravenous infusion (20 ml/kg every h by mouth before infusion, then 5 ml/kg every h by mouth during intravenous rehydraton). For intra- venous supplementaton, it is recommended that compound soluton of sodium lactate (see chapter 28. If the intravenous route is unavailable, a nasogastric tube is also suitable for administering oral rehydraton soluton, at a rate of 20 ml/kg every h. If the child vomits, the rate of administra- ton of the oral soluton should be reduced. Note: The soluton may be prepared either from prepackaged sugar/salt mixtures or from bulk substances and water. Solutons must be freshly prepared, preferably with recently boiled and cooled water. Accurate weighing and thorough mixing and dissoluton of ingredients in the correct volume of clean water is important. Adult- Fluid and electrolyte loss in acute diarrhoea; 200 to 400 ml soluton afer every loose moton. Adverse Efects Vomitng- may indicate too rapid administraton; hypernatraemia and hyperkalaemia may result from overdose in renal impairment or administraton of too concentrated a soluton. Antdotes and Substances Used in Poisoning These notes are only guidelines and it is strongly recom- mended that poisons informaton centres (Appendix 5) be consulted in cases where there is doubt about the degree of risk or about appropriate management. Patents who have taken poisons with delayed actons should also be admited, even if they appear well; delayed-acton poisons include acetylsalicylic acid, iron, lithium, paracetamol, paraquat, tricyclic antdepressants and warfarin. However, it is ofen impossible to establish with certainty the identty of the poison and the size of the dose but informaton on the type and tming of poisoning may be useful for symptomatc management. Cardiac conducton defects and arrhythmias ofen respond to correcton of underlying hypoxia, acidosis, or other biochemical abnormalites. Hypothermia which may develop in patents who have been unconscious for some hour is best treated by wrapping the patent in blankets to conserve body heat.

Diabetes and Hypoglycaemia Beta blockers may mask tachycardia occurring with hypoglycaemia generic 25mg benadryl otc allergy shots effects on immune system. Metronidazole is active in vitro against most obligate anaerobes cheap 25 mg benadryl allergy medicine makes me depressed, but does not appear to possess any clinically relevant activity against facultative anaerobes or obligate aerobes buy generic benadryl 25 mg on-line allergy relief. Against susceptible organisms buy 25mg benadryl with amex allergy symptoms due to mold, metronidazole is generally bactericidal at concentrations equal to or slightly higher than the minimal inhibitory concentrations. Metronidazole has been shown to have in vitro and clinical activity against the following organisms: Anaerobic Gram-Negative Bacilli, including: Bacteroides species including the Bacteroides fragilis group (B. Anaerobic Gram-Positive Bacilli, including: Clostridium species and susceptible strains of Eubacterium. Anaerobic Gram-Positive Cocci, including: Peptococcus species and Peptostreptococcus species. Accordingly, for such patients, doses below those usually recommended should be administered cautiously. This possible drug interaction should be considered when metronidazole is prescribed for patients on this type of anticoagulant therapy. The simultaneous administration of drugs that induce microsomal liver enzymes, such as phenytoin or phenobarbital, may accelerate the elimination of metronidazole, resulting in reduced plasma levels; impaired clearance of phenytoin has also been reported. Metronidazole should not be given to patients who have taken disulfiram within the last 2 weeks. Instances of a darkened urine have also been reported, and this manifestation has been the subject of a special investigation. Although the pigment which is probably responsible for this phenomenon has not been positively identified, it is almost certainly a metabolite of metronidazole and seems to have no clinical significance. Infusion (ventilated): Dilute 3mg/kg in 50ml 5% dextrose and run at 0-5ml/hr (0-5mcg/ kg/min) Intranasal: Sedation: 0. The following paradoxical reactions have been observed: Excitability, irritability, aggressive behavior, agitation, nervousness, hostility, anxiety, sleep disturbances, nightmares and vivid dreams. Hepatic: Hepatomegaly, transient elevations of serum transaminases and alkaline phosphatase. Patients with renal impairment on milrinone infusions may develop progressive vasodilation leading to escalating noradrenaline requirements. If noradrenaline requirement is increasing consider whether it is appropriate to cease milrinone. Significant hypotension due to peripheral vasodilation is common and is generally treated with noradrenaline. Milrinone may aggravate outflow tract obstruction in hypertrophic subaortic stenosis. Respiratory depression occurs most frequently in the elderly and debilitated patients as well as in those suffering from conditions accompanied by hypoxia or hypercapnia when even moderate therapeutic doses may dangerously decrease pulmonary ventilation. Morphine should be used with extreme caution in patients with chronic obstructive pulmonary disease or cor pulmonale, and in patients having a substantially decreased respiratory reserve, hypoxia, hypercapnia, or preexisting respiratory depression. In such patients, even usual therapeutic doses of morphine may decrease respiratory drive while simultaneously increasing airway resistance to the point of apnea. Hypotensive Effect Morphine sulphate controlled-release tablets, like all opioid analgesics, may cause severe hypotension in an individual whose ability to maintain his blood pressure has already been compromised by a depleted blood volume, or a concurrent administration of drugs that lower blood pressure. Respiratory: Respiratory depression, apnoea, respiratory arrest, Gastrointestinal: Dry mouth, biliary tract spasm, laryngospasm, anorexia, diarrhoea, cramps, taste alteration, constipation, ileus, intestinal obstruction, increases in hepatic enzymes. Cardiovascular: Flushing of the face, chills, tachycardia, bradycardia, palpitation, faintness, syncope, hypotension, hypertension. If stored at cool temperatures precipitation may occur – this will redissolve at room temperature. Moxifloxacin, given as an oral tablet, is well absorbed from the gastrointestinal tract. Aerobic Gram-Positive Microorganisms: Staphylococcus aureus (methicillin-susceptible strains only), Streptococcus pneumoniae (including penicillin-resistant strains), Streptococcus pyogenes. Aerobic Gram-Negative Microorganisms: Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, Moraxella catarrhalis. Convulsions and neuropsychiatric complications Convulsions have been reported in patients receiving quinolones. Hypersensitivity Reactions Serious and occasionally fatal hypersensitivity (anaphylactic) reactions, some following the first dose, have been reported in patients receiving quinolone therapy. Pseudomembranous Colitis Pseudomembranous colitis has been reported with nearly all antibacterial agents, including moxifloxacin, and may range in severity from mild to life-threatening. Peripheral Neuropathy Rare cases of sensory or sensorimotor axonal polyneuropathy affecting small and/or large axons resulting in paraesthesias, hypoesthesias, dysesthesias and weakness have been reported in patients receiving quinolones. Tendon Effects Ruptures of the shoulder, hand, achilles tendon or other tendons that required surgical repair or resulted in prolonged disability have been reported in patients receiving quinolones. Oral administration of quinolones with antacids containing aluminum or magnesium, with sucralfate, with metal cations such as iron, or with multivitamins containing iron or zinc, or with formulations containing divalent and trivalent cations such as (didanosine) chewable/buffered tablets or the paediatric powder for oral solution, may substantially interfere with the absorption of quinolones, resulting in systemic concentrations considerably lower than desired. Central Nervous System: Insomnia, nervousness, anxiety, confusion, somnolence, tremor, vertigo, paraesthesia. Naloxone prevents or reverses the effects of opioids including respiratory depression, sedation and hypotension. In such cases, an abrupt and complete reversal of narcotic effects may precipitate an acute abstinence syndrome. Several instances of hypotension, hypertension, ventricular tachycardia and fibrillation, and pulmonary edema have been reported. These have occurred in postoperative patients most of whom had pre-existing cardiovascular disorders or received other drugs which may have similar adverse cardiovascular effects. Although a direct cause and effect relationship has not been established, naloxone injection should be used with caution in patients with pre-existing cardiac disease or patients who have received potentially cardiotoxic drugs. In post-operative patients, larger than necessary dosages of naloxone may result in significant reversal of analgesia. Hypotension, hypertension, ventricular tachycardia and fibrillation, and pulmonary oedema have been associated with the use of naloxone postoperatively Naloxone! It enhances cholinergic action by facilitating the transmission of impulses across neuromuscular junctions. Neurologic: Dizziness, convulsions, loss of consciousness, drowsiness, headache, dysarthria, miosis and visual changes. Cardiovascular: Cardiac arrhythmias (including bradycardia, tachycardia, A-V block and nodal rhythm), cardiac arrest, syncope and hypotension. Respiratory: Increased oral, pharyngeal and bronchial secretions, dyspnea, respiratory depression, respiratory arrest and bronchospasm. Gastrointestinal: Nausea, salivation, cramp, emesis, diarrhoea, flatulence and increased peristalsis. Oedema, burning sensation, blisters, rash, or pinching at the application site were also noted. Gastrointestinal reactions: Nausea, vomiting, dyspepsia, abdominal pain, diarrhoea Neurological System: Abnormal dreams Nicotine!
