The efficacy and safety of an extended-release combination of loratadine plus pseudoephedrine sulfate (SCH 434) was compared with that of a tablet containing chlorpheniramine maleate plus pseudoephedrine sulfate (CTM-D) in 131 patients with symptomatic seasonal allergic rhinitis. Patients were randomly assigned to receive either SCH 434 (loratadine 5 mg and pseudoephedrine sulfate 120 mg) or CTM-D (chlorpheniramine maleate 12 mg and pseudoephedrine sulfate 120 mg) twice daily for 2 weeks. Evaluations were made after 3, 7, and 14 days of treatment. Demographics (age, race, sex, and duration of seasonal allergic rhinitis) and baseline total symptom scores were comparable between groups. Both combination products were effective in relieving the symptoms of allergic rhinitis. Improvement in total symptom scores was 54% on day 3 and 65% on day 14 in the SCH 434 group versus 57% on day 3 and 64% on day 14 in the CTM-D group. Individual symptom scores (nasal discharge, stuffiness, nasal itching, sneezing, and ocular symptoms) responded similarly. A smaller proportion of patients in the SCH 434 group reported side effects, especially dry mouth (7% vs 19%, P = 0.07), fatigue (6% vs 25%, P < 0.01), and sedation (7% vs 22%, P < 0.03). In conclusion, the combination of loratadine plus pseudoephedrine sulfate was equally as effective as a classic antihistamine (chlorpheniramine maleate) plus pseudoephedrine sulfate but had a lower incidence of side effects.

Continuous epidural analgesia consisting of an opioid with or without a local anesthetic agent is a commonly employed technique for pain relief after thoracotomy. In this study, we prospectively evaluated the use of continuous epidural analgesia in 1,324 patients undergoing elective thoracotomy between 1987 and 1993. Epidural pain management was continued for 1 to 3 postoperative days. Patients experienced excellent pain relief, with mean visual analog pain scores of 2.4, 1.7, and 1.4 on postoperative days 1, 2, and 3, respectively. Side effects occurred most frequently in the first 24 hours postoperatively; the incidence of pruritus was 14.1%; nausea, 11.2%; hypotension, 4.3%; sedation, 3.3%; and numbness, 1.1%. Respiratory depression (< 8 breaths per minute) occurred in 1 patient who received 16 mg of supplemental morphine sulfate over a 2-hour period. The incidence of inadequate analgesia (a visual analog pain score of 7 or more persisting for 1 to 2 hours after an epidurally administered bolus) was 3.8%. The results from this study support the use of standard protocols for dosing guidelines, the treatment of inadequate analgesia, and the management of side effects. Daily evaluation by a team member of the postoperative analgesia services section of the Department of Anesthesiology enhances patient care and minimizes adverse effects.

This prospective, randomized, controlled investigation compared the effects of three prophylactic mu-opioid antagonists, epidural butorphanol (BU) 3 mg, epidural nalbuphine (NB) 10 mg, and oral naltrexone (NX) 6 mg, on postcesarean epidural morphine analgesia. After randomization, 102 term parturients underwent cesarean delivery with epidural anesthesia, 2% lidocaine and epinephrine 1:200,000. When the umbilical cord was clamped, each patient received one epidural solution (containing morphine 4 mg plus either saline or treatment drug), and one oral capsule (containing either placebo or treatment drug) in a double-blind manner. Maternal outcomes included pain and satisfaction [assessed with 100-mm visual analog scales (VAS)], and the incidence and severity of respiratory depression, somnolence, pruritus, nausea, and emesis. Through the first 12 h postpartum, the BU group achieved significantly greater analgesia than the morphine sulfate (control) (MS), NB, and NX groups, a significantly lower incidence of severe pruritus than the MS group, and significantly greater satisfaction than MS and NX groups. Epidural morphine and BU promoted better analgesia and satisfaction than any previously documented postcesarean regimen.

Pruritus is a common side effect after neuraxial administration of the opioids; particularly morphine sulfate. Ondansetron has been used to treat the pruritus in patients with cholestatic diseases or renal insufficiency, suggesting that pruritus may be mediated by serotonin. We administered ondansetron to four patients suffering from pruritus due to the perioperative administration of opioids. Pruritus disappeared within few minutes in three of these patients. Future studies are necessary to evaluate the efficacy of ondansetron for the treatment as well as the prevention of this opioid-induced effect.

Twenty male alcoholics (age: 40-60 years) abstinent for 2 weeks and affected by liver steatosis with positive laboratory indexes of biliary stasis (increased levels of total and free bilirubin, gamma glutamil transpeptidase and hepatic alkaline phosphatase) were treated for 3 weeks with 500 ml/day p.o. of placebo (aqua fontis) (Group I:N. 10) or sulfureous sulfate calcic water of the "Pergoli" spring-Tabiano (Parma, Italy) (Group II: N. 10). The abovementioned laboratory indexes of biliary stasis were measured in groups I and II before and after water treatments and were compared to values obtained in 10 age-matched normal male subjects. In addition, both before and after water treatments, alcoholic patients underwent a double blind test, where individual sensations of itch were scored. Finally, in order to establish the effect of water treatments on gallbladder contraction, the bidimensional areas at maximal longitudinal and transverse diameters were echographically evaluated in alcoholics before (time 0) and 20, 40 and 60 minutes after drinking in 10 minutes a 500 ml load of placebo (Group I) or Pergoli water (Group II). The results showed a significant reduction in the measured gallbladder area in group II alcoholics, but not in patients of group I. Furthermore, three weeks of treatment with Pergoli water significantly reduced to normal total and direct bilirubin levels, the enzyme markers of biliary stasis and the subjective sensation of itch. These parameters did not change in alcoholics of group I after placebo treatment. These data demonstrate that the oral administration of sulfureous sulfate calcic water Pergoli exerts a cholagogue activity in humans. The cholagogue activity together with the wellknown choleretic effect of this water argue in favor of the possibility for its use as support treatment to the therapy of biliary stasis in alcoholism.

A once-daily dose of PF-402 60 mg and twice-daily doses of sustained-release morphine sulfate tablets (MSC) 30 mg were repeatedly administered in cancer patients in a cross-over design. Their plasma concentrations were measured, and the pharmacokinetics of PF-402 and MSC were compared. A total of 7 subjects in the study were taking commercially sold MSC 60 mg daily (30 mg twice-daily) prior to the study and had "mild" or "no" pain at the start of the study. Plasma morphine concentrations of PF-402 were longer-lasting and showed smaller fluctuations than those of MSC. Repeated administration of the same daily doses of PF-402 and MSC produced similar plasma concentrations for periods of 24 hr and 12 hr. PF-402 administration produced a Tmax of 7.4 hr, and an MRT of 9.8 hr, all longer than those with MSC. Moreover, no significant difference was observed in AUC between PF-402 and MSC. These results indicate that the sustained-release characteristics of PF-402 are superior to those of MSC, and that the two drugs have a similar absorption pattern. Adverse drug reactions (ADRs) were observed in all 7 subjects and consisted of 6 incidences of constipation, 3 incidences of nausea, 2 incidences of itching, and 1 incidence each of vomiting and somnolence. Study drug administration was not discontinued in any case due to ADRs, and no symptoms indicating physical or psychic drug dependence were observed. No abnormal laboratory values related to study drug administration were observed. The above results indicate that once-daily administration of PF-402 is sufficient to maintain plasma concentrations obtained with twice-daily administration of MSC. As the safety of PF-402 is confirmed, the drug is considered to be a useful sustained release formulation in the treatment of cancer pain.

More than 2200 subjects were enrolled in the MorphiDex (MS:DM) development program, with a 1:1 (weight:weight) ratio of morphine sulfate (MS) to dextromethorphan hydrobromide (DM). Of the 1400 subjects exposed to MorphiDex, more than 350 subjects were treated for at least 6 months, and over 200 subjects were treated for a year or longer. The clinical population comprised an approximately equal number of men (46.2%) and women (53.8%), ranging in age from 16 to 96 years, and mostly Caucasian (91.8%). The most frequent (54.8%) daily dose of MorphiDex for subjects enrolled in the clinical program was 120 mg or less. Slow DM metabolizers took significantly lower daily doses of MorphiDex than rapid metabolizers without a significant difference in the incidence of adverse events. Plasma bromide concentrations were low and showed a wide margin of safety for both slow and rapid DM metabolizers. There were no clinically significant treatment-related changes in clinical laboratory tests, neurological examinations, or vital signs. The most common adverse events seen in the multiple dose controlled studies were nausea, dizziness, vomiting, somnolence, constipation, confusion, asthenia, headache, and pruritus. With long-term treatment, the prevalence of adverse events was greatest during the first month of MorphiDex exposure and then decreased over time. The incidence of constipation remained fairly constant over time.

The most common cause of acral cyanosis is vascular spasm which can be induced by several drugs. An 87-year-old woman developed red and livid skin lesions on the fingers of both hands and several toes one month after beginning treatment with quinine sulfate 200 mg daily. The skin lesions progressed to necrosis in some areas. Quinine sulfate is a widely prescribed drug for nocturnal cramps. The following side effects may develop, particularly in the elderly: exanthems, pruritus, urticaria, erythema multiforme, purpura and photosensitivity. Our case points to the possibility of acral necrosis and demonstrates the efficacy of vasodilator treatment.

Metal contact allergy is a common problem in the general population. Diagnostic and therapeutic medical-surgical procedures in which metals can be responsible for eczema are diverse. Endovascular aortic surgery is still an experimental but less invasive technique. A generalized eczematous dermatitis elicited by metal of an endovascular prosthesis is presented. An abdominal aortic aneurysm was diagnosed in a 79-year-old woman. Endoluminal repair with a straight Vanguard endograft was successful. 3 weeks later, she suffered a severe episode of erythema and eczema on the legs. Since then, she complained of continuous pruritus with eczema and excoriated papules. The dermatitis and also the patch test pathology showed eczema. Patch testing was positive to nickel sulfate and cobalt chloride. An endograft semi-quantitative metal analysis was performed with plasma-induction joint mass-spectrometry. The self-expanding metal stent was mainly composed of nickel (approximately 55%) and titanium (21%) with reinforcing thread of platinum. Antimony was detected only in the polyester textile. These results are consistent with Nitinol composition. The need for preoperative patch testing for metals is controversial. Enquiry about metal allergy is recommended before endoluminal surgical procedures. In the near future, the design of endografts must take into account the possibility of this sort of reaction.

The high risk of occupational contact dermatitis in dental personnel are well accepted throughout the world. There are few reports concerning occupational skin disease in dental personnel in Korea. The purposes of this study were to investigate the frequency, characteristics and causative factors of contact dermatitis in Korean dental technicians. Recording of personal history, physical examination and patch tests with the Korean standard series and dental screening series were performed in 49 dental technicians. Most of the subjects were exposed to a variety of compounds, including acrylics, metals, plaster, alginate, etc. 22 (44.9%) subjects had contact dermatitis, present or past, and the site involved was the hand in all 22. The most common clinical feature of hand dermatitis was itching (77.3%); scaling, fissuring and erythema were other common clinical features. Metals, including potassium dichromate (24.5%), nickel sulfate (18.4%), mercury ammonium chloride (16.3%), cobalt chloride (12.2%) and palladium chloride (10.2%), showed high positive rates in patch test results of 49 dental technicians. 7 positive reactions to the various acrylics were found in 3 subjects. In our study, the frequency and clinical features of the contact dermatitis showed a similarity to other reports, though the patch test results were somewhat different; a higher patch-positive reaction to metals and a relatively lower patch-positive reaction to acrylics than the patch test results reported in Europe.
