Liniments are liquid or semi-liquid preparations meant for application to the skin. The liniments are usually applied to the skin with friction and rubbing of the skin (on the affected area).
• The liniment may be an alcoholic or oily solution or emulsion.
• In alcoholic preparation, alcohol helps in the
penetration of medicament to the skin and also increases its counter-irritant
effect and rubefacient action.
• In oily liniments, arachis oil is commonly used
which spreads more easily on the skin.
• Some lubricants may contain soap which helps in the easy
application of liniment on the skin.
• Liniment should not be applied on broken skin because it may cause excessive irritation.
• Liniment contains medicament possessing analgesic
action, rubefacient, and counter-irritant properties and is applied in joint
pain, muscle pain, etc.
