We document the results of a repeat survey, which updates Agell and Lundborg (1995), on wage rigidity in a sample of 159 Swedish manufacturing firms, conducted during the severe Swedish recession of the 1990s. It is found that not even a prolonged period of very high unemployment and quite low inflation softened workers' resistance to wage cuts. We discuss possible reasons for this. In addition, we report new evidence on underbidding, efficiency-wage mechanisms, and unemployment persistence.
1. Carbohydrate and lipid metabolism and the capacity to perform prolonged submaximal physical exercise were studied in six young healthy subjects treated in a randomized double-blind fashion for 2 days with either placebo, the non-selective beta-adrenoceptor antagonist propranolol (80 mg b.i.d.) or the cardioselective agent metoprolol (100 mg b.i.d.). On day 3, 1 h after the last dose, the subjects exercised for 30 min periods followed up 10 min rest up to the point of exhaustion. 2. The capacity to perform exercise was decreased with both beta-adrenoceptor antagonists. However, at an equal degree of beta 1-adrenoceptor blockade, all subjects could exercise for a longer period of time on the cardioselective agent as compared with the non-selective drug. 3. Blood glucose levels decreased during exercise irrespective of the type of treatment, but the attenuation occurred most rapidly on propranolol. At exhaustion the average non-esterified fatty acid levels had increased 256% on placebo, 148% on metoprolol and 65% on propranolol. A significant positive correlation was found between changes in non-esterified fatty acid levels during exercise and total working time. It is concluded that beta-adrenoceptor blockade diminishes the capacity for prolonged sub-maximal exercise at least in part by reducing the availability of substrates to the working muscles.
The pharmacokinetic and pharmacodynamic properties of a new multiple-unit, controlled-release (CR) formulation of metoprolol (metoprolol succinate, 95 mg once daily), which has almost constant (zero-order) release properties over most of a 24-h dose interval, have been compared with those of conventional metoprolol tablets (metoprolol tartrate, 100 mg once daily and 50 mg twice daily), in 12 healthy male volunteers. The steady-state plasma concentrations of metoprolol after five days of treatment varied less throughout the day with the CR than with the conventional formulation. This was associated with a considerably lower peak plasma concentration and the achievement of a significantly higher plasma concentration at the end of the dose interval. Similarly, the effect on exercise-induced tachycardia was maintained at a relatively constant level throughout the day after treatment with the CR formulation. A significantly greater effect 24 h after administration was achieved with the CR formulation, when compared with once-daily dosing with metoprolol tablets, 100 mg. Twice-daily dosing with metoprolol tablets, 50 mg, produced a similar beta 1-blocking effect at the end of the dose interval to that observed with metoprolol CR. Although the steady-state plasma concentrations indicated significantly lower systemic availability for the CR formulation, compared with both regimens of metoprolol tablets, the total effect over the dose interval, expressed as the area under the efficacy curve (AUEC), was similar for the three treatments. The relationship between steady-state plasma concentrations and the pharmacodynamic efficacy at corresponding times, indicated that plasma concentrations were more effectively utilized after the administration of the CR formulation than after the conventional tablet regimens.(ABSTRACT TRUNCATED AT 250 WORDS)
Omeprazole is effective in reducing esophageal acid exposure in premature infants with pathological acid reflux on 24-h pH probe; however, the far more complex issues of safety and efficacy have yet to be addressed.
This paper is the first to specifically focus on the integration of refugee immigrants into the Swedish labor market. Using highly detailed register data on blue collar workers it is shown that refugees' employment lags that of natives basically for their whole life time in Sweden. Time in Sweden reduces drastically the unemployment days, though from very high initial levels. Refugees from culturally distant Iran/Iraq and Horn of Africa experience considerably more days in unemployment than refugees from the less distant Eastern Europe and Latin America. The differences are large during the first 20 years in Sweden but some convergence occurs thereafter. Following a business cycle upturn this paper finds that the reduction of refugees' unemployment is half of that of natives'. Since refugees arrive at different ages, high numbers of unemployment days are recorded also for relatively old refugees with the highest number for those above 30.
1. Ten healthy subjects were given 20 mg omeprazole EC (enteric coated) granules once daily for 8 days. An i.v. tracer dose of [14C]‐omeprazole was given simultaneously with the first and last oral doses and blood sampling was performed thereafter. In order to study the extent of absorption at minimal acid exposure, a single dose of 20 mg omeprazole was also given as a buffered solution, before and after the treatment with EC granules. 2. Kinetic parameters of omeprazole after the i.v. tracer dose were unchanged on repeated dosing while AUC increased by approximately 40% for the solution and 60% for the EC granules. 3. The increased AUC is caused by an increased systemic availability, which may be explained by a decreased first‐pass elimination during repeated treatment and/or by a reduced degradation of omeprazole in the stomach secondary to the profound decrease in intragastric acidity caused by the drug. 4. The implication of these findings is that the antisecretory effect of therapeutic doses of omeprazole must be studied during repeated administration and not judged from studies using single doses only.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
