This is a question about demand and supply.
When there is a significant inflation, the Central Bank would like to increase the interest rate to reduce the money supply in the market.
When the interest rate is increased, people may intend to save their money in the bank and get the interest. Similarly, it would also be more costly to borrow money for any other economic activities (e.g. LBO or whatever). It eventually turns out that the money supply in the market is reduced.
Once the money supply is reduced, the price level will also be reduced so as to meet the new demand and until the economy goes to a new equilibrium point at lower price level. This is what the Central Bank wants to do to make a drop in the price level.
