Abstract
Based on theoretical principles and experimental
observations, Health expenditure and real GDP in each country has a reciprocal
relationship and the effect of each of these variables on other variables
regardless of their interactions in terms of econometric methods would not be
very reliable. Accordingly, this study investigated the relationship between
pharmaceutical expenditures, health care expenditures and GDP in Iran. Methods: The
study was analytical and ecological correlation type and Partial Correlation
and regression tests have been used. The variables in this study consisted of
gross domestic product, total pharmaceutical expenditures, Per capita drug
consumption and total health expenditures. Data needed from different sources
has been collected and wereanalyzed by SPSS software.Results: In the
significance level (P <0.01), variables, GDP per capita, total health
expenditure and total pharmaceutical expenditures with per capita drug
consumption had a statistically significant relationship. Based on study
results, the variables of GDP, total health expenditure and total
pharmaceutical expenditures 99.3 percent of the variance in per capita drug
consumption and 99.8 percent change in total pharmaceutical expenditures can be
explained. According to the results of the regression, the variable per capita
health expenditures with a beta standard (β=0.759 and β=0.987) better than
variable of economic growth predicted the per capita drug consumption and total
pharmaceutical expenditures variables.Conclusion: In the years studied, per
capita drug consumption with total health expenditure, total pharmaceutical
expenditures and per capita gross domestic production was statisticaly
correlated.
