Drug instillation, also known as medication instillation, is the administration of a medicine, generally in liquid form, either drop by drop or with a catheter, into a body space or cavity.[1] Drop by drop administration may be done for eye drops, ear drops, or nose drops.[1] A catheter can be used to perform intravesical drug delivery into the urinary bladder.[2] It differs from therapeutic irrigation in that the irrigation solution is removed within minutes, but the instillate is left in place.[1]
