Angiotensin converting enzyme (ACE) inhibitors and their implications for the dental surgeon.

Angiotensin enzyme converting (ACE) inhibitors are a widely prescribed group of drugs used in the management of hypertension and heart failure. Several unwanted effects are associated with ACE inhibitors and this paper highlights those significant to the dental surgeon. Of particular concern is the problem of angioedema, which can be life threatening. Three case reports are presented that illustrate this problem and the management is discussed.

Assessment of the aversive consequences of acute and chronic administration of the melanocortin agonist, MTII.

BACKGROUND: The synthetic melanocortin (MC) agonist, melanotan-II (MTII), reduces food intake and body weight for hours to days after administration. One early report on the effect of MTII suggested that part of its anorexic action may be mediated by aversive consequences. In that experiment, MTII was found to support a mild conditioned taste aversion (CTA). OBJECTIVE: The present experiments replicate and extend those findings in two additional CTA paradigms to further characterize the aversive effects of MTII in rats. METHODS: Experiment 1 simultaneously assessed the ability of MTII to support CTA and reduce food intake, using a small oral infusion of a novel taste as the conditioned stimulus. Experiment 2 assessed the aversive consequences of chronic MTII administration. To accomplish this, we paired implantation of lithium chloride (LiCl)-, MTII- or saline-containing osmotic minipumps with a constantly available novel flavor. After 7 days, rats received a choice test between the minipump-paired flavor and a previously available neutral flavor. RESULTS: Rats with saline minipumps exhibited no preference for either flavor. By contrast, rats in both the LiCl and MTII minipump groups significantly preferred the neutral flavor, indicating the development of a CTA. Additionally, CTA produced by administration of MTII was found to be more resistant to extinction than that produced by LiCl. CONCLUSIONS: The reduction in food intake caused by MTII is accompanied by aversive consequences regardless of route of administration. These results present difficulties for the development of MCs-based therapies for obesity.

Lansoprazole triple therapy for Helicobacter pylori--is 5 days enough?

BACKGROUND: Seven-day proton pump inhibitor triple therapy is currently the treatment of choice for Helicobacter pylori infection. It is unclear whether triple therapy for less than 7 days might preserve efficacy while at the same time improving patient acceptability and compliance. AIM: To evaluate the Helicobactericidal efficacy, ulcer healing capacity and patient acceptability of a 5-day lansoprazole-based triple therapy regimen. METHODS: Sixty-nine consecutive patients with H. pylori-positive peptic ulcer received lansoprazole 30 mg twice daily in combination with metronidazole 400 mg twice daily and clarithromycin 250 mg twice daily for 5 days. Ulcer healing medication was not continued after the 5-day regimen. H. pylori status was assessed before and at least 4 weeks after therapy by rapid urease test and histology. Adverse events and compliance were assessed by direct questioning. RESULTS: All 69 patients attended for repeat endoscopy and 63 were H. pylori-negative after therapy giving a cure rate of 91%, (95%, Cl: 85-98%). Of the 59 patients with active ulcers, 58 were healed at repeat endoscopy giving an ulcer healing rate of 98% (95% Cl: 92-100%). All patients fully complied with therapy and mild adverse events, mainly gastrointestinal, were reported by 11 patients (16%). CONCLUSIONS: Five-day lansoprazole triple therapy is an effective regimen for H. pylori infection which combines a high cure rate and ulcer healing efficacy with the advantages of excellent patient acceptability and compliance.

Bismuth-containing single-antibiotic 1-week triple therapy for Helicobacter pylori eradication.

BACKGROUND: Although bismuth was both the first drug shown to alter the natural history of peptic ulcer disease and also a constituent of the first very effective eradication regimens, it has been excluded from the newer regimens, despite its safety and low cost, in favour of two antibiotics. AIM: To asses a novel 1-week regimen consisting of bismuth, clarithromycin and a proton pump inhibitor in routine clinical practice. METHODS: One hundred and three consecutive patients with peptic ulcer disease and antral biopsies containing Helicobacter pylori were given a 7-day course of treatment with bismuth (tripotassium dicitrato bismuthate chelate) 120 mg q.d.s., clarithromycin 500 mg t.d.s. and lansoprazole 30 mg o.d. Completeness of eradication was assessed by a l3C-urea breath test, in all except three patients, at least 4 months later. RESULTS: Of the 100 patients who were assessed in this open treatment study 84 (84%; 95% CI: 77-91%) had a negative breath test. Minor side-effects were reported by 14% and more troublesome side-effects (nausea, vomiting, diarrhoea, hallucinations, nasty taste and body pains) were reported by 10%. CONCLUSIONS: A 1-week course of triple therapy including bismuth, clarithromycin and a proton pump inhibitor is effective in routine clinical practice and is well tolerated.

Taste loss to terbinafine: a case-control study of potential risk factors.

1. To identify risk factors associated with taste loss to terbinafine, we performed a case-control study of 87 reports of probably terbinafine-induced taste loss and 362 controls on terbinafine without taste loss, who had filled prescriptions from the same pharmacy and GP. Data on general health, diet, alcohol, smoking, drug use and medical history were collected by means of a self-administered questionnaire. 2. The mean latent period between first intake of terbinafine and taste loss was 35 days. Most patients recovered within 4 months after discontinuation. Cases were significantly older than controls. The odds ratio of taste loss in patients of 65 years and older was 4.4 in comparison with persons younger than 35 years of age (95% CI: 1.4-16.1). The risk in persons with a body mass index (BMI) below 21 kg m-2 was 4.4 times higher than in those with a BMI of more than 27 kg m-2 (95% CI: 1.6-14.2). The risk of taste loss in patients of 55 years and older with a BMI below 21 kg m-2 was 12.8 times higher than that in patients below 35 years of age (95% CI: 1.9-88.6). 3. A low BMI, a history of taste loss, and ageing are risk factors for developing taste loss to terbinafine. Prescription of this drug to elderly patients with low BMI and low daily intake of nutrients requires careful follow-up.

Terbinafine: tolerability in general medical practice.

Four open, prospective, postmarketing studies with consistent protocols were undertaken, involving over 25,000 patients and nearly 3600 physicians in four European countries (UK, Netherlands, Germany and Austria). The purpose was to determine the tolerability of terbinafine when prescribed to a large, unselected patient population in general medical practice. Patients were recruited from dermatology departments and from general and family practitioners. All received at least one dose of terbinafine. No specific exclusion criteria were applied. The only treatment instructions provided were those contained in the manufacturer's product information. Patients were monitored for adverse events at baseline, during treatment, and at the end of treatment. Of the 25,884 patients entering the study, 38.6% (9991) had concomitant disease, 42.8% (11,078) were taking other medications, and 22.7% (5876) were older than 60 years. The predominant indication for prescribing terbinafine was onychomycosis. Mean duration of treatment was 13.2 weeks. No adverse events were reported in 89.5% (23,167) of patients. The remaining 10.5% (2717) reported one or more adverse events, primarily gastrointestinal (4.9%) or dermatological (2.3%). A total of 115 serious adverse events were recorded, but of these only four were probably and eight possibly related to terbinafine. There were no reported drug-drug interactions, even in patients receiving concomitant medications metabolized by cytochrome P-450 enzymes. There were also no clinically significant drug-disease interactions. In conclusion, terbinafine is well tolerated in an unselected general practice population. This confirms its good tolerability previously established during controlled clinical trials.

Efficacy and safety of metamizol vs. acetylsalicylic acid in patients with moderate episodic tension-type headache: a randomized, double-blind, placebo- and active-controlled, multicentre study.

We assessed the efficacy and safety of oral single doses of 0.5 and 1 g metamizol vs. 1 g acetylsalicylic acid (ASA) in 417 patients with moderate episodic tension-type headache included in a randomized, double-blind, placebo- and active-controlled, parallel, multicentre trial. Eligibility criteria included 18-65 years of age, history of at least two episodes of tension-type headache per month in the 3 months prior to enrollment, and successful previous pain relief with a non-opioid analgesic. Treatment arms were metamizol 0.5 g (n = 102), metamizol 1 g (n = 108), ASA 1 g (n = 102) and placebo (n = 105). The analgesic efficacy of 0.5 and 1 g metamizol vs. placebo was highly statistically significant (alpha: 0.025; one-sided) for sum of pain intensity differences, maximum pain intensity difference, number of patients with at least 50% pain reduction, time to 50% pain reduction, maximum pain relief and total pain relief. A trend towards an earlier onset of a more profound pain relief of 0.5 and 1 g metamizol over 1 g ASA was noticed. All medications including placebo were almost equally safe and well tolerated.

Metallic taste: an unusual reaction to botulinum toxin A.

BACKGROUND: Botulinum neurotoxin formulations are safe and effective agents for the treatment of facial rhytides. OBJECTIVES: A patient is described who complained of metallic taste after each treatment with botulinum toxin A (BTX-A). RESULTS: The sensation of metallic taste diminished after successive treatments with BTX-A, despite adequate dosing for cosmetic purposes. CONCLUSION: Metallic taste is associated with the use of numerous medications; however, the pathogenesis remains unclear. Alteration in zinc metabolism, which may occur with BTX-A administration, has been suggested as a possible mechanism. Although this is the first known report of dysgeusia after BTX-A, physicians and patients may be reassured that the taste alteration was self-limited and was not significantly problematic for the patient in our case.

Amifostine in simultaneous radiochemotherapy of advanced head and neck cancer.

The authors discuss the results of 3 studies of their group reflecting the possible role of amifostine in simultaneous radiochemotherapy (RCT) of advanced head and neck cancer. In a controlled phase II trial (1995 through 1996), 39 patients were included in this pilot investigation. A control group (n = 14) received simultaneous RCT of the head and neck region with an irradiation dose of 60 Gy and 2 cycles of carboplatin (700 mg/m(2) cumulative dose). Twenty-five patients received the same basic therapy and an additional 500-mg dose of amifostine before each chemotherapy. Amifostine was administered less than 45 minutes before the end of radiotherapy. The authors observed a dramatic reduction of typical radiotherapy-associated toxicities (mucositis, xerostomia, loss of taste, dysphagia). The hematologic side effects (leukocytopenia, anemia, thrombocytopenia) also were decreased significantly. The overall survival rate and locoregional control of both groups were comparable after 12 months. In a controlled intensification trial (1997 through 1999), the authors included 76 consecutive patients (69 men, 7 women) with pharyngeal cancer (oropharynx, n = 33; hypopharynx, n = 43). The tumors were characterized as unresectable and locally advanced without distant metastasis. All patients received a conventional radiotherapy (2-Gy single dose, daily fractionation) up to doses of 60 Gy and an additional 10 Gy as a boost in the tumor-infiltrated region. A dose of carboplatin, 70 mg/m(2), was given to a group of 45 patients on days 1 through 5 and 29 through 33 of radiotherapy (RCT arm). The resulting cumulative dose was 700 mg/m(2). A group of 31 patients (RCTintens arm) received the same dose of carboplatin on days 1 through 5, 22 through 26, and 43 through 47 or 1 through 5, 15 through 19, 29 through 33, and 43 through 47 of radiotherapy (cumulative dose 1.05 to 1.40 mg/m(2)). All patients received 500 mg of amifostine before each carboplatin administration. If the tumor volume was less than 20 cm(3), we observed an increased 1-year overall survival rate (91% v 71%) and time to progression (17 months v 10 months). If the tumor volume was greater than 20 cm(3), we observed comparable treatment results in both groups (1-year survival rate, 60% v 61%; time to progression, 13 months v 12 months). In a long-term follow-up investigation (1999 through 2000), 531 patients (89 women, 442 men) were analyzed according to their toxicities during regular follow-up investigations at our outpatient facility. All patients were treated by surgery or radio(chemo)therapy because of an advanced head and neck cancer. A total of 218 of 531 patients received the antineoplastic therapy without cytoprotection. An additional 313 patients received their RCT combined with amifostine administration before administration of the radiosensitizer. A significant influence of cytoprotection was registered in the following toxicities: xerostomia, fibrosis, loss of taste, and dysphagia. No impact was seen on the development of interstitial lymph edema and esophageal stenosis. Amifostine could be integrated in simultaneous radiochemotherapy of advanced head and neck cancer patients. The authors favor the administration of amifostine before chemotherapeutics alone. Selective cytoprotection could decrease the main acute toxicities (mucositis, xerostomia, dysphagia) as well as late side effects (xerostomia, loss of taste, fibrosis) of this form of combined treatment. The enhanced therapeutic index may be changed into a prognostic benefit for selected patients with unresectable tumors, if the volume is smaller than 20 cm(3).
