Since the onset of coma is often rapid with this poisoning diabetes type 1 diet restrictions 500 mg metformin with visa, induced emesis is contraindicated diabete soccer player order metformin 500mg, though spontaneous vomiting often occurs blood glucose and yeast infections purchase metformin 500mg free shipping. If the patient has ingested a large amount diabetes test kit free generic metformin 500 mg amex, has not vomited, and is seen within one hour of exposure, consideration should be given to gastric emptying by lavage as outlined in Chapter 2. Isopropyl alcohol is well adsorbed to charcoal, so activated charcoal should probably be administered, as outlined in Chapter 2. Supportive care for hypotension and respiratory depression is critical to survival and should be administered whenever possible in an intensive care setting. If hypoglycemia occurs, glucose administration is indicated in order to maintain normoglycemia. Hemodialysis has been reported to be beneficial in patients with severe poisoning unresponsive to standard supportive therapy. Glutaraldehyde is very similar to formaldehyde in its toxicity and treatment, although it is probably slightly less toxic. Glutaraldehyde is commonly prepared as an aqueous solution at a 2% concentration, and is slightly alkaline in this solution. It has been reported to cause respiratory irritation, resulting in rhinitis5,6 and occupational asthma. At high dosage, given orally, it results in gastrointestinal irritation with diarrhea, which may be hemorrhagic. If a large amount has been ingested and retained, and the patient is seen within one hour of exposure, consider gastric emptying as described in Chapter 2. Administration of activated charcoal should be considered, as described in Chapter 2. If patient has been in an area with strong odor of glutaraldehyde due to vaporization, remove to fresh air area and administer oxygen as needed. All share the capacity, in sufficient concentration, to behave as caustic agents, capable of causing rather severe, caustic burns. The three agents most commonly used as detergent disinfectants are benzalkonium chloride, cetrimide, and cetylpyridium chloride. Concentrated solutions are usually only available in industrial settings, such as production of consumer products, or for use in hospitals for disinfectant purposes. Toxicology In low-concentration solutions, these agents have been reported to cause eye discomfort as well as skin rashes and irritation. Likewise, strong concentrations will result in caustic burns to lips, oral mucosa, esophagus, and stomach. If a high-concentration solution has been applied to skin, aggressive skin contamination and treatment of burns is appropriate. Gastric emptying and other methods of gastrointestinal decontamination are contraindicated in these poisonings. If a highly concentrated solution was ingested or oral burns are noted, the patient needs urgent endoscopy for grading of the caustic injury. The endoscopy should be performed within 24 hours to minimize the risk of perforation from the procedure. Although corticosteroids are commonly used to treat these burns, their use remains controversial. Use of other agents, such as H2 antagonists and sulcralfate, has been reported but remains controversial at this time. There is very little human experience with poisonings, as these concentrations do not appear to be significantly toxic. Toxicology Chlorhexidine is poorly absorbed from skin or the gastrointestinal tract. If a low concentration solution is ingested or applied to the skin, mild local irritation can be seen. Contact dermatitis, urticaria, and anaphylaxis have followed repeated skin exposures to this agent. If ingestion of a large quantity has occurred within an hour and the patient has not vomited, gastrointestinal decontamination as described in Chapter 2 should be considered. If a highly concentrated solution has been ingested, manage as a caustic ingestion as described in the cationic detergents, without gastrointestinal decontamination. If eye exposure has occurred, the eyes should be vigorously irrigated and a careful ophthalmologic exam should be performed for corneal injury. Chloramine, a disinfectant used by many municipal water supplies, is an infrequent cause of acute poisonings.

Accurate diagnosis and classification of seizure/syndrome type is critical to selection of appropriate pharmacotherapy. Patient characteristics such as age, comorbid conditions, ability to comply with the prescribed regimen, and presence or absence of insurance coverage can also influence the choice of antiepileptic drugs. Pharmacotherapy of epilepsy is highly individualized and requires titration of the dose to optimize antiepileptic drug therapy (maximal seizure control with minimal or no side effects). If the therapeutic goal is not achieved with monotherapy, a second drug can be added or a switch to an alternative single antiepileptic drug can be made. If a second antiepileptic drug is added it should have a different mechanism of action from the first, although there is no clear evidence in humans to support this. The appropriate use of antiepileptic drugs requires a thorough understanding of their clinical pharmacology, including mechanism of action, pharmacokinetics, adverse reactions, and drug interactions, as well as available dosage forms. Patients with epilepsy also may display neurodevelopmental delay, memory problems, and/or cognitive impairment. Although, by convention, the focus of drug treatment is on the abolition of seizures, clinicians must also try to address these common comorbidities. The rate of recurrence of a first unprovoked seizure within 5 years ranges between 23% and 80%. Each year, approximately 125,000 new epilepsy cases occur in the United States; only 30% are in people younger than 18 years of age at the time of diagnosis. There is a bimodal distribution in the occurrence of the first seizure, with one peak occurring in newborn and young children and the second peak occurring in patients older than 65 years of age.

Systemic drugs that influence sebum production include high-dose estrogens, antiandrogens (cyproterone acetate), spironolactone, and the retinoid isotretinoin. Estrogen-containing oral contraceptives can be useful in the treatment of acne in some women. Oral antiandrogens, such as spironolactone and cyproterone acetate, can also be useful in the treatment of acne. There are limited data to support the effectiveness of oral corticosteroids in the treatment of acne. Oral corticosteroid therapy is of temporary benefit in patients who have severe inflammatory acne. In patients who have well-documented adrenal hyperandrogenism, low-dose oral corticosteroids may be useful in treatment of acne. Estrogen-containing contraceptive agents have been studied for the treatment of acne. There is good evidence and consensus opinion that other estrogen-containing oral contraceptives are also equally effective. Spironolactone may cause hyperkalemia, particularly when higher doses are prescribed or when there is cardiac or renal compromise. Cyproterone combined with ethinyl estradiol (in the form of an oral contraceptive) has been found effective in the treatment of acne in females. No cyproterone/estrogencontaining oral contraceptives are approved for use in the United States. Oral corticosteroids have two potential modes of activity in the treatment of acne. One study demonstrated that low-dose corticosteroids suppress adrenal activity in patients who have proven adrenal hyperactivity. It has been shown to reduce sebogenesis and may also inhibit sebaceous gland activity, growth of P. Oral isotretinoin is approved for the treatment of severe recalcitrant nodular acne. Oral isotretinoin is also useful for the management of less severe acne that is treatment-resistant (unresponsive to adequate treatment, reasonable courses of antibiotic, or combination peelers and antibiotics administered for 6 weeks to 3 months) or that is producing either physical or psychologic scarring. Because of its teratogenicity and the potential for many other adverse effects, this drug should be prescribed only by those physicians knowledgeable in its appropriate administration and monitoring. Two different forms of contraception must be started 1 month before and continue at least 1 month (but normally 4 months) after therapy. Alternatively, lower doses can be used for longer time periods, with a total cumulative dose of 120 to 150 mg/kg. In patients with severely inflamed acne, an even greater initial dose reduction may be required. In the most severe cases of acne, consideration of pretreatment with oral corticosteroids may also be appropriate. Isotretinoin, a vitamin A derivative, interacts with many of the biologic systems of the body, and consequently has a significant pattern of adverse effects. Side effects include those of the mucocutaneous, musculoskeletal, and ophthalmic systems, as well as headaches and central nervous system effects. Most of the adverse effects are temporary and resolve after the drug is discontinued.

Syndromes

Injectable testosterone replacement regimens are the preferred treatment for symptomatic patients with primary or secondary hypogonadism because they are effective diabetic diet foods buy metformin 500 mg with amex, inexpensive blood glucose 4 hours after eating buy 500 mg metformin visa, and not associated with the bioavailability problems or hepatotoxic adverse effects of oral androgens diabetes type 2 uptodate buy generic metformin 500mg online. In the ideal testosterone replacement regimen blood glucose walgreens generic metformin 500 mg free shipping, the medication would mimic the normal circadian pattern of serum testosterone concentrations such that peak and trough concentrations occur in the early morning and late afternoon, respectively; produce serum concentrations in the normal range; produce serum concentrations of dihydrotestosterone and estradiol, which are metabolites of testosterone that mimic the normal physiologic pattern; and produce minimal adverse effects. Indications Testosterone replacement regimens are indicated in symptomatic patients with primary or secondary hypogonadism, as confirmed by both the presence of a decreased libido and low serum concentrations of testosterone. Simultaneous serum luteinizing hormone levels help to distinguish patients with primary hypogonadism, who have elevated luteinizing hormone levels, from those with secondary hypogonadism, who have decreased luteinizing hormone levels. Primary hypogonadism can be a characteristic of aging men who undergo andropause, in which the Leydig cells of the testes slowly and progressively decrease testosterone production. Of these derivatives, methyltestosterone and fluoxymesterone are more resistant to hepatic catabolism and can be taken in smaller daily doses, which are potentially safer. However, oral alkylated derivatives of testosterone are not metabolized to dihydrotestosterone or estradiol, and are associated with a higher incidence of serious hepatotoxicity and therefore are not preferred for management of hypogonadism. An alternative to oral administration is the testosterone buccal system (Striant), which is applied to the gum above the upper incisor teeth twice per day. One advantage of this route of administration is that the drug bypasses first-pass hepatic catabolism, which allows for increased bioavailability of testosterone. Several testosterone esters have been formulated for intramuscular injection, with different durations of action (see Table 92­3). The shorter-acting testosterone propionate, which requires dosing 3 times per week, has been replaced with testosterone cypionate or enanthate, which can be dosed every 2, 4, or 6 weeks in most patients. An even longer-acting parenteral testosterone is available as a subcutaneous implant for dosing every 3 to 6 months. These testosterone formulations produce suprapharmacologic patterns of serum testosterone during the dosing interval, which have been linked to mood swings in some patients. Topical testosterone replacement regimens can be delivered as once-daily patches or gel. Testosterone patches increase serum testosterone levels into the normal range in 2 to 6 hours. However, unlike oral or injectable supplements, transdermal testosterone patches applied at bedtime or testosterone gel applied each morning produce physiologic patterns of serum testosterone levels throughout the day. Scrotal skin is thinner and has a richer vascular supply than does the skin on the arms or thighs. Therefore, application of Testoderm patches produces excellent absorption of the hormone. However, the patch can fall off when the scrotum becomes damp or moist, when the patient exercises, or if the scrotum is excessively hairy. The addition of absorption enhancers and different adhesives has been linked to a higher incidence of contact dermatitis with Androderm patches compared with the original Testoderm scrotal patch. The hormone is absorbed quickly, within 30 minutes, but several hours may be required for complete absorption of the dose. For this reason, the patient should be reminded to wait at least 5 to 6 hours after application before showering. To prevent inadvertent transfer of testosterone gel to others, the patient should thoroughly wash his hands with soap and water after administration of a dose, and allow the application site to dry undisturbed for several minutes before dressing or covering it. Thus, a dose should not be increased until the patient has used one particular dose for at least this time period. Before initiating any testosterone replacement regimen in patients 40 years and older, patients should be screened for benign prostatic hyperplasia and prostate cancer. Both of these diseases are testosterone-dependent conditions and theoretically could be worsened by exogenous administration of testosterone. To screen for these conditions, a prostate-specific antigen serum concentration should be obtained and a digital rectal examination of the prostate performed. These tests are generally repeated at 1-year intervals after treatment is started. Gynecomastia can occur as a result of conversion of testosterone to estrogen in peripheral tissues. Testosterone replacement regimens are contraindicated in patients with breast cancer and untreated prostate cancer. Although serum lipoprotein perturbations may occur, testosterone replacement regimens have a neutral effect in that they decrease both total cholesterol and high-density lipoprotein cholesterol levels. No cases of cardiovascular disease have been reported with testosterone replacement regimens.
