Elixir is monophasic distinct liquids for oral use for administering potent or nauseous drugs by incorporating pleasurable flavours. The motor vehicle comprises a significant quantity of ethanol or sucrose as well as antimicrobial preservatives to boost the stability of the formulation [twenty five].
TDDS are topically administered medicaments in the shape of patches that supply drugs for systemic effects at predetermined and controlled price.
A paste is largely an ointment with a large proportion of insoluble solids extra. A large amount of particulate make a difference stiffens the system. Compared to the ointment, paste has decrease permeability, lower maceration and lessen warmth. When applied to the skin, they sort an excellent protecting barrier [15].
A transdermal patch or skin patch is undoubtedly an adhesive drug patch that is put on the skin to deliver a certain dose of drug in to the blood with the pores and skin.
