Drug Delivery approaches for Parenterals

Parenteral Drug Delivery has been developed alternative to the normal route of administration. The success depends on clinical as well as on patient compliance. This route is mainly used for the drugs having poor aqueous solubility and this route improves the patient compliance and decreases the systemic availability. Chitosan is used as micro particles, liposomes, granules, and gels for oral and parenteral drug delivery. Parenteral administration route is the most common for delivery of active drug substances with a narrow therapeutic index. This route of administration may cause less cardiac attacks and respiratory attacks. Parenteral delivery still remains the major mode of administration for protein and peptide therapeutics.
