There are two known types of atelectasis. The first type is called acute atelectasis which usually results from surgery involving the opening of the chest cavity or the abdominal area. This type of atelectasis may also result from physical trauma to the lungs like during car accidents or stabbing incidents.

It may take up to 3-6 weeks to see a lowering of your blood pressure. Cholestyramine and colestipol can decrease the absorption of metolazone. If you are taking either of these drugs, separate metolazone from cholestyramine by at least 4 hours and from colestipol by at least 2 hours.
