Drug delivery methods that have been necessary to overcome the various physical, physiological, and biochemical barriers that limit macromolecular drug delivery. Identifying non-invasive (or minimally invasive) methods of delivering macromolecules to not only improve compliance but also therapeutic benefit.
The approach described in this chapter is an exploration of the possibility of using macromolecule-drug conjugate for directed delivery of therapeutic agents.
Since active targeting such as antibody or receptor-mediated delivery will be mentioned in other chapters, discussions will be limited to the use of conjugates in which a drug is Cited by: 9. Delivery of macromolecules into cells and tissues such as skin is a major challenge. This obstacle poses a particular challenge for the delivery of siRNA where cellular and tissue level transport barriers need to be overcome.
siRNAs are potential therapeutics for various dermatological diseases including psoriasis, atopic dermatitis, and cancer; however, their Cited by: This review article describes the current status and future perspectives of site-specific drug delivery by means of macromolecular carrier systems.
Basic aspects and recent advances of targeted delivery of 1) conventional drugs, 2) protein drugs, and 3) gene medicines including antisense oligonucleotides and plasmid DNA, are reviewed from a pharmacokintic Cited by: Presenting Better Treatments Through Bioavailability Enhancement, Macromolecule Delivery And Optimized Tabletting Two scientists from Catalent Pharma Solutions, the global leader in oral drug delivery technology, are to present at ExL Pharma’s 2ndEnhancing Drug Bioavailability and Solubility conference in Boston, MA.
The use of sugar-macromolecule conjugates or glycoconjugates may be divided into two types: (i) those in which the macromolecule is itself the drug or therapeutic agent; or (ii) those in which the macromolecule plays a pivotal role in aiding the delivery of the drug or therapeutic agent.
This review will primarily focus on the type of macromolecule.

Efforts to reach the full therapeutic potential of macromolecules (biopharmaceuticals) for clinical care are thus limited by a lack of effective, efficient and convenient drug delivery. Nonclassical transport proteins and peptides: An alternative to classical macromolecule delivery systems Article Literature Review in Journal of Pharmaceutical Sciences 92(9) On-body delivery systems An interesting device scenario is presented if injection time is treated as an opportunity instead of a challenge.
When applying the Hagen-Poiseuille equation (Equation 1) for an autoinjector, the flow rate, Q, of 1 mL or 2 mL in perhaps 10 seconds, is driven largely by the acceptable operating time for the if the injection device.
Transition of hydrophilic macromolecules into the cellular compartments without interruption of biological membrane is the main goal of the novel drug delivery systems.
The effective passage of therapeutic agent across the biological membrane could decrease the quantity of administrated drug as well as its side effect on the normal by: intracellular trafficking, and even nuclear delivery, in target cells. In the field of gene transfer, for instance, both viral and nonviral vectors have been used to deliver sense and an-tisense nucleic acids into mammalian cells [1, 2].

The stratum corneum protects the human body, but also severely limits drug delivery into and across the skin.
The historical and theoretical understanding of the type of compound that will permeate the skin is based on the “dalton rule” (1, 2), where it is assumed that most compounds permeating the SC have a relatively small molecular. site specific drug delivery system • Insufficient localization of targeted systems into tumour cells.
