Liquid preparations for oral administration

Liquids are easier to swallow and act more quickly than solid dosage forms, but may be unpalatable and relatively unstable. Solutions contain dissolved drugs and may be difficult to formulate or to make palatable; suspensions are usually more pleasant to take but accuracy of dosing may be affected by settling of drug particles. The dose of a drug in liquid and solid form may differ because different drug compounds are often used. Liquids contain many additives which can give rise to adverse affects in the patient.
