Coricidin products seemed to be one of the over-the-counter medications being reportedly abused by adolescents, as observed from the Texas Poison Center Network data. This retrospective chart review investigated the occurrence of abuse, developed a patient profile, and defined the clinical effects resulting from the abuse of Coricidin products. Data collected from the Texas Poison Center Network Toxic Exposure Surveillance System database included human exposures between 1998 and 1999, patients > or = 10y old, intentional use or abuse, and single substance ingestion of I of the tablet formulations of Coricidin. Thirty-three cases from 1998 and 59 cases from 1999 were reviewed. Of these cases, 85% met the inclusion criteria. Of the 7 medications searched, only 4 substances were coded for: Coricidin D, Coricidin D (long acting), Coricidin D (cold, flu & sinus) and Coriciding HBP. These contain a combination of dextromethorphan hydrobromide, chlorpheniramine maleate, phenylpropanolamine hydrochloride, and acetaminophen. Of the 78 cases, 63% were male and 38% were female. The mean age was 14.67 years, 77% being between 13 to 17 years old. Eighteen different symptoms were reported: tachycardia 50%, somnolence 24.4%, mydriasis and hypertension 16.7%, agitation 12.8%, disorientation 10.3%, slurred speech 9%, ataxia 6.4%, vomiting 5.1%, dry mouth and hallucinations 3.9%, tremor 2.6%, and headache, dizziness, syncope, seizure, chest pain, and nystagmus each 1.3%; 12.8% of the calls originated from the school nurse. The incidence of abuse reported increased 60% from 1998 to 1999. This worrisome trend suggests increased abuse of these products.

Existing therapies for major depressive disorder (MDD) have either limited efficacy and/or poor tolerability. The present study examined the effects of duloxetine, a potent and balanced dual reuptake inhibitor of serotonin (5-HT) and norepinephrine (NE), in patients with MDD. Adult patients (N = 267) with MDD were randomly assigned to receive duloxetine (60 mg/day) or placebo in this 9-week, multi-center, double-blind, parallel-group clinical trial. Efficacy was evaluated using the 17-item Hamilton Depression Rating Scale (HAMD(17)), Visual Analog Scales (VAS) for pain, Clinical Global Impression of Severity (CGI-S), Patient's Global Impression of Improvement (PGI-I), and Quality of Life in Depression Scale (QLDS). Safety was evaluated by assessing discontinuation rates, adverse event rates, vital signs, and laboratory tests. Duloxetine (60 mg QD) significantly reduced the HAMD(17) total score compared with placebo at the end of 9-week therapy. Estimated probabilities of response and remission were 65 and 43%, respectively, for duloxetine compared with 42 and 28% for placebo. Duloxetine also reduced overall pain, back pain, shoulder pain and time in pain while awake significantly more than placebo. Global measures of improvement, including PGI-I and QLDS, were significantly improved by duloxetine compared with placebo. Discontinuations due to adverse events were more frequent for duloxetine-treated patients (12.5%) than for placebo-treated patients (4.3%). Nausea, dry mouth, dizziness, and constipation were more frequent for duloxetine than placebo. There was no significant incidence of hypertension, nor any other safety issues. Duloxetine 60 mg administered once daily appears to be a safe and effective treatment for MDD.

Optimal medications for children with attention-deficit/hyperactivity disorder (ADHD) would be effective, well tolerated, and long acting and not cause mood swings or worsen comorbid conditions. Current medications work on brain dopamine and/or norepinephrine systems, which are thought to be involved in ADHD. The medication class with the most evidence of efficacy in ADHD is stimulants, but they may be abused, are effective for only 4 to 12 hours, and may cause mood swings or increase tic severity. In recent years, alternative treatments have been explored. Tricyclic antidepressants have efficacy comparable to that of stimulants but may cause constipation, dry mouth, tremors, blood pressure changes, and potentially serious side effects including cardiac conduction and repolarization delays. Monoamine oxidase inhibitors may improve ADHD symptoms but are associated with severe dietary restrictions. Serotonin reuptake inhibitors have little or no effect in ADHD but may improve comorbid depression. Bupropion, although less effective than stimulants, may improve both ADHD symptoms and comorbid depression. Antihypertensive agents may improve impulsivity, hyperactivity, and comorbid tics but cause sedation or rebound hypertension. Atomoxetine, which is being developed for ADHD, reduces symptoms of ADHD without exacerbating comorbid conditions and is associated with only minor side effects, including subtle changes in blood pressure and heart rate. Before prescribing a treatment, physicians should consider the appropriateness and effectiveness of any medication for children with ADHD, who may be less tolerant of side effects and less able to monitor and express concerns about their well-being than adults.

This 6-month randomized study evaluated the safety and efficacy of sibutramine in 57 overweight Hispanic patients with hypertension. Following a 2-week washout to confirm the diagnosis of hypertension, antihypertensive medication was adjusted to achieve a blood pressure less than 140/90 mm Hg before institution of either sibutramine 10 mg or placebo once a day. A body mass index in excess of 27 kg/m2 was required for entry. At study end, weight had changed from 75.4+/-9.6 to 70.0+/-9.5 kg in the sibutramine group and from 77.9+/-9.0 to 74.5+/-9.4 kg in the placebo group. In the sibutramine group, systolic blood pressure was 127.8+/-5.8 mm Hg after stabilization and 125.2+/-8.5 mm Hg after completion of the trial; respective values for diastolic blood pressure were 82.4+/-3.7 and 81.5+/-4.6 mm Hg. With placebo, blood pressure dropped from 129.0+/-7.1/80.9+/-4.9 mm Hg to 122.8+/-9.7/80.3+/-5.4 mm Hg at the same timepoints. In the sibutramine group, 14 patients reported 21 adverse events, most frequently headache (n=5), constipation (n=4), and dry mouth (n=4). In the placebo group, 13 patients had 20 adverse events. Sibutramine is safe and effective in overweight Hispanic patients with hypertension, but monitoring of blood pressure and titration of antihypertensive medication are necessary.

Centrally acting imidazoline I(1)-receptor agonists such as moxonidine and rilmenidine induce peripheral sympathoinhibition via the stimulation of hypothetical I(1)-receptors in the rostral ventrolateral medulla. Because of a rather weak affinity for alpha(2)-adrenoceptors, the use of these agents is associated with a lower incidence of adverse reactions, such as sedation and dry mouth, compared with classic centrally acting alpha(2)-adrenoceptor agonists (clonidine, guanfacine, methyldopa). The antihypertensive efficacy of moxonidine and rilmenidine is well documented, and they display a favorable hemodynamic profile. Their tolerability is better than that of the aforementioned centrally acting antihypertensive agents. However, long-term outcome data for moxonidine and rilmenidine are not available, and neither is a quantitative evaluation of their adverse effects. There exists some uncertainty with respect to the identity of the imidazoline I(1)-receptor, which has so far not been cloned. Furthermore, it would be desirable to develop highly selective I(1)-receptor agonists as successor drugs to moxonidine and rilmenidine. Although available data indicate that I(1)-receptor agonists are effective in patients with hypertension, comparative data versus agents such as beta-blockers, diuretics, calcium channel antagonists and ACE inhibitors are required to establish their position in the treatment of hypertension. Finally, I(1)-receptor agonists have potential in the treatment of patients with CHF and those with the metabolic syndrome; syndrome X.

Atomoxetine is the first nonstimulant drug approved by the United States Food and Drug Administration (FDA) for the treatment of attention-deficit-hyperactivity disorder (ADHD), and the only agent approved by the FDA for the treatment of ADHD in adults. Atomoxetine is a norepinephrine transport inhibitor that acts almost exclusively on the noradrenergic pathway. Its mechanism of action in the control and maintenance of ADHD symptoms is thought to be through the highly specific presynaptic inhibition of norepinephrine. Clinical trials to evaluate the short-term effects of atomoxetine in children and adults have shown that atomoxetine is effective in maintaining control of ADHD. Likewise, long-term trials have determined that atomoxetine is effective in preventing relapse of ADHD symptoms without an increase in adverse effects. A comparative trial of atomoxetine with methylphenidate in school-aged children indicated similar safety and efficacy without the abuse liability associated with some psychostimulants. The most commonly reported adverse effects in children and adolescents are dyspepsia, nausea, vomiting, decreased appetite, and weight loss. The rates of adverse events in the trials were similar for both the once- and twice-daily dosing regimens. The discontinuation rate was 3.5% in patients treated with atomoxetine versus 1.4% for placebo and appeared to be dose dependent, wit a higher percentage of discontinuation at dosages greater than 1.5 mg/kg/day. In clinical trials involving adults, the emergence of clinically significant or intolerable adverse events was low. The most common adverse events in adults were dry mouth, insomnia, nausea, decreased appetite, constipation, urinary retention or difficulties with micturition, erectile disturbance, dysmenorrhea, dizziness, and decreased libido. Sexual dysfunction occurred in approximately 2% of patients treated with atomoxetine. Atomoxetine should be used with caution in patients who have hypertension or any significant cardiovascular disorder. Overall, atomoxetine therapy in patient with ADHD appears to be effective in controlling symptoms and maintaining remission, with the advantages being comparable efficacy with that of methylphenidate, a favorable safety profile, and non-controlled substance status. Additional long-term studies are needed to determine its continued efficacy for those who require lifelong treatment, and comparative trials against other stimulant and nonstimulant agents.

Overactive bladder is associated with symptoms of urgency, with or without urge incontinence, usually with daytime frequency and nocturia in the absence of local pathological factors. Muscarinic receptor antagonists (antimuscarinics) are the first-line pharmacotherapy. Tolterodine, a competitive, nonselective antimuscarinic specifically developed for the treatment of overactive bladder, demonstrated tissue selectivity for the bladder over the parotid gland in an animal model. As of March 5, 2003, the immediate-release (IR) formulation had been approved in 72 countries and the extended-release (ER) formulation had been approved in 28 countries, and tolterodine had been administered to 5 million patients. This review evaluates the benefit-risk profile of tolterodine in the treatment of adults with overactive bladder, summarising clinical trial and postmarketing surveillance data. Tolterodine has been found to significantly reduce micturition frequency, urgency perception and the number of episodes of urge incontinence and increase the volume voided per micturition. Dry mouth, an antimuscarinic class effect, is the most commonly reported adverse effect but is mostly mild to moderate in severity. Serious adverse effects are reported infrequently. Based on summary and review of postmarketing surveillance and clinical trial safety data received by the market authorization holder and contained in the Periodic Safety Update Reports for tolterodine, several monitored serious events of the gastrointestinal tract (e.g. ileus or haemorrhage), nervous system (e.g. syncope, convulsions and memory disorders) and cardiovascular system (e.g. ventricular arrhythmia, atrial fibrillation, palpitations, bradycardia, transient ischaemic attacks and hypertension) were not considered related to tolterodine. QT or corrected QT (QTc) prolongation was not observed in any of the five cases of verified ventricular arrhythmia in patients administered tolterodine; there is insufficient evidence to indicate that tolterodine causes ventricular arrhythmia or extrasystoles or any specific type of cardiac rhythm abnormality. The safety profile of tolterodine is similar in patients aged > or =65 years and in younger adults. Clinically relevant drug interactions are limited to cytochrome P450 3A4 inhibitors, such as ketoconazole, and co-administration with such agents warrants a tolterodine dosage decrease. In addition, tolterodine IR 2mg twice daily is similar in efficacy to oxybutynin IR 5mg three times daily, and tolterodine ER 4 mg once daily is similar in efficacy to oxybutynin ER 10mg once daily. Dry mouth occurred less frequently with tolterodine than oxybutynin, and moderate to severe dry mouth occurred more than three times less frequently. Based on the low frequency of adverse events, the absence of unexpected adverse events and the very low frequency of serious adverse events, we conclude that tolterodine is a well tolerated treatment for overactive bladder in adults, in whom it should be considered as first-line therapy.

The overweight and obesity represent severe problems for the health management system of developed countries. In the evolution of obesity, beside genetic background, the environmental factors also play important roles. In the daily routine, the majority of obese patients need drug treatment, over the diet and physical activity. Among the available medicines the inhibitors of monoamine re-uptake causes dry mouth, tachycardia, sleeplessness and elevated blood pressure, therefore, due to the frequently associated obesity and hypertension many physicians avoid using these compounds. The orlistat as a selective inhibitor of pancreatic and enteral lipase enzymes impedes the absorption of the highest calorie containing nutrients, the fats exerting beneficial effects in the treatment of obesity. The abdominal bloating and diarrhea as side effects of the drug may act as an advantage in many cases, since these happen especially in those cases when the patient neglects the previously suggested low fat diet and therefore the drug induced diarrhea and bloating may mean a feed-back for the patient in respect of the proper diet. Recent studies show many beneficial biochemical changes in obesity related pathological metabolic processes during the administration of orlistat. The authors, in their present work review in short the role of orlistat in the treatment of slimming cure.

A 34-year-old man was admitted in a coma after a nightlong abuse of cocaine and alcohol, whereupon he fell and convulsed at home. There was a fracture of the nose, hyperpyrexia, tachycardia and hypertension. Dry mouth and mydriasis were suggestive of anticholinergic poisoning. Physostigmine 3 mg were slowly administered intravenously, followed by complete neurological recovery and normalisation of the body temperature. There was no brain damage. Cocaine and atropine were found in the patient's urine. Several users of cocaine in various European countries have recently developed a central anticholinergic syndrome due to adulteration of cocaine with atropine. In the presence of indications for such an intoxication, physostigmine is the antidote of first choice.

Overactive bladder (OAB) affects millions of people in the United States and is associated with poor health, impaired quality of life, social isolation, and depressive symptoms. Despite the high prevalence of this syndrome, studies show that it is not adequately addressed by the busy primary care physician, who may be preoccupied with management of other chronic diseases perceived as more serious such as heart disease, diabetes mellitus, and hypertension. Pharmacologic flexible-dosing studies with anticholinergic agents offer a relatively simple strategy for optimal management of OAB: physician-initiated, patient-managed dose adjustment. Recent flexible-dosing studies with extended-release oxybutynin, darifenacin, and solifenacin suggest that urge urinary and total incontinence episodes may be reduced significantly with a flexible-dosing strategy. Dose adjustment may improve the therapeutic outcome, facilitating a balance between efficacy and anticholinergic side effects such as dry mouth. Flexible-dosing studies indicate that dry mouth, the adverse effect most frequently seen with the use of anticholinergic agents, seldom leads to study withdrawal. Patient-initiated control of OAB symptoms may be achieved in 1 month by following established protocols.
