A lotion is undoubtedly an aqueous fluid preparation for external use without friction. These are placed on the skin specifically or pored on a suitable dressing and lined with a water-proof dressing to lower evaporation [14].
Drug Absorption Price: ER drugs generally Possess a slower absorption price, resulting in a far more gradual buildup in the drug while in the bloodstream. In distinction, SR medications give you a speedier nevertheless sustained release.
This mechanism is especially helpful for remedies that can cause abdomen discomfort or for drugs greatest absorbed in the here intestines.
