          Abstract

          Background

          We report a case of a patient with recurrent severe hypoglycemia after initiating the drug rasagiline (Azilect) for Parkinson disease.

          Case presentation

          A 25-year-old Emirati woman who had been diagnosed with Parkinson disease due to a genetic mutation since the age of 18 years presented to our hospital. She had been treated with a rotigotine patch 2 mg per day along with carbidopa + levodopa + entacapone 25 mg/100 mg/200 mg (Stalevo) over these years. Recently, her Stalevo had been changed to rasagiline (a monoamine oxidase B inhibitor). Soon after this change, she started experiencing recurrent documented severe hypoglycemia requiring hospitalization. Her hypoglycemic symptoms completely disappeared after 5–7 days of drug withdrawal. Despite detailed evaluation, no other causal relationship was documented except for rasagiline.

          Conclusions

          To the best of our knowledge, this case report documents an unknown association between rasagiline and hypoglycemia.

          Drug-drug interactions among elderly patients hospitalized for drug toxicity.

          Drug-drug interactions are a preventable cause of morbidity and mortality, yet their consequences in the community are not well characterized. To determine whether elderly patients admitted to hospital with specific drug toxicities were likely to have been prescribed an interacting drug in the week prior to admission. Three population-based, nested case-control studies. Ontario, Canada, from January 1, 1994, to December 31, 2000. All Ontario residents aged 66 years or older treated with glyburide, digoxin, or an angiotensin-converting enzyme (ACE) inhibitor. Case patients were those admitted to hospital for drug-related toxicity. Prescription records of cases were compared with those of controls (matched on age, sex, use of the same medication, and presence or absence of renal disease) for receipt of interacting medications (co-trimoxazole with glyburide, clarithromycin with digoxin, and potassium-sparing diuretics with ACE inhibitors). Odds ratio for association between hospital admission for drug toxicity (hypoglycemia, digoxin toxicity, or hyperkalemia, respectively) and use of an interacting medication in the preceding week, adjusted for diagnoses, receipt of other medications, the number of prescription drugs, and the number of hospital admissions in the year preceding the index date. During the 7-year study period, 909 elderly patients receiving glyburide were admitted with a diagnosis of hypoglycemia. In the primary analysis, those patients admitted for hypoglycemia were more than 6 times as likely to have been treated with co-trimoxazole in the previous week (adjusted odds ratio, 6.6; 95% confidence interval, 4.5-9.7). Patients admitted with digoxin toxicity (n = 1051) were about 12 times more likely to have been treated with clarithromycin (adjusted odds ratio, 11.7; 95% confidence interval, 7.5-18.2) in the previous week, and patients treated with ACE inhibitors admitted with a diagnosis of hyperkalemia (n = 523) were about 20 times more likely to have been treated with a potassium-sparing diuretic (adjusted odds ratio, 20.3; 95% confidence interval, 13.4-30.7) in the previous week. No increased risk of drug toxicity was found for drugs with similar indications but no known interactions (amoxicillin, cefuroxime, and indapamide, respectively). Many hospital admissions of elderly patients for drug toxicity occur after administration of a drug known to cause drug-drug interactions. Many of these interactions could have been avoided.

            Comprehensive review of rasagiline, a second-generation monoamine oxidase inhibitor, for the treatment of Parkinson's disease.

            Inhibitors of monoamine oxidase (MAO) with selectivity and specificity for MAO type B (MAO-B) prolong the duration of action of both endogenously and exogenously derived dopamine. Rasagiline [N-propargyl-l(R)-aminoindan] is a second-generation propargylamine pharmacophore that selectively and irreversibly inhibits brain MAO-B and is specifically designed for the treatment of Parkinson's disease (PD). The aim of this study was to review the pharmacology, tolerability, and clinical efficacy of rasagiline in the treatment of PD. MEDLINE (1966-April 2007), the Cochrane Database of Systematic Reviews, and International Pharmaceutical Abstracts (1970-April 2007) were searched for original research and review articles published in English. The search terms were monoamine oxidase, neuroprotection, Parkinson disease, propargylamine, rasagiline, and selegiline. The reference lists of articles were also consulted, as was information provided by the manufacturer of rasagiline. Data from 63 clinical and laboratory studies were analyzed. Based on the results from those studies, we concluded that rasagiline PO QD, at the therapeutic dosage range of 0.5 to 1 rag/d, is effective and well tolerated and completely, selectively, and specifically inhibited MAO-B. Pharmacologically, rasagiline was found to be or =70 years) patients with early or advanced PD. Pharmacologically, rasagiline has the potential to augment the vasopressor effects of diet-derived tyramine (ie, the "cheese reaction"). However, clinical challenge studies of tyramine have found this unlikely to occur even with ingestion of supraphysiologic amounts of tyramine. In experimental models, rasagiline has been found to have neuroprotective properties that may be independent of MAO-B inhibition. Based on this review, rasagiline has been found to be well tolerated and effective in the treatment of early PD and as adjunctive treatment in motor fluctuations. Whether rasagiline is associated with clinically significant neuroprotection (ie, disease modification) in PD is the subject of ongoing clinical trials.

              Clinical pharmacology of rasagiline: a novel, second-generation propargylamine for the treatment of Parkinson disease.

              Rasagiline is a novel second-generation propargylamine that irreversibly and selectively inhibits monoamine oxidase type B (MAO-B). For the management of Parkinson disease (PD), rasagiline is efficacious across the span of PD stages ranging from monotherapy in early disease to adjunctive treatment in patients with advancing disease and motor fluctuations. Rasagiline completely and selectively inhibits MAO-B with a potency 5 to 10 times greater than selegiline. Unlike the prototype propargylamine selegiline, which is metabolized to amphetamine derivatives, rasagiline is biotransformed to aminoindan, a non-amphetamine compound. Rasagiline is well tolerated with infrequent cardiovascular or psychiatric side effects, and at the recommended therapeutic dose of up to 1 mg once daily, tyramine restriction is unnecessary. In addition to MAO-B inhibition, the propargylamine chain also confers dose-related antioxidant and antiapoptotic effects, which have been associated with neuroprotection in multiple experimental models. Thus, in addition to symptomatic benefits, rasagiline offers the promise of clinically relevant neuroprotection.
