Medical Usage
In pharmacology, a liquid dosage form is a preparation that contains one or more active ingredients dissolved or suspended in a suitable base. Examples include syrups, elixirs, suspensions, and solutions. These are often used for patients who have difficulty swallowing solid dosage forms, such as tablets or capsules.
Bodily fluids, such as blood, urine, and saliva, are also often referred to as 'liquids'. These fluids are crucial for the functioning of the body and are often analyzed in laboratory tests to diagnose and monitor various medical conditions.
