Rapid advances in drug discovery have led to the identification of a number of compounds with good therapeutic potential.

Nanoparticles can also cross the blood–brain barrier, which could make them useful for delivering drugs that target brain tumours or diseases that affect the central nervous system.

The use of PVA copolymer-based film can solve the problems associated with lack of film adhesion... to tablets containing large amounts of waxy excipient or a lubricant.

The design of accurate and robust analytical methodology is instrumental to developing orally inhaled and nasal drug products (OINDPs) and their appropriate control programmes.

Different chemistries and viscosities of HPMC can be combined to modulate release profile and, in some cases, result in a more robust formulation.

The introduction of biomolecules into cells is a key technology for research in biological sciences.

The adequate absorption and transport of drugs in the body is part of optimal therapy. Drug administration perorally is easy, common and traditional, but occasionally alternative routes are required.

Insulin is one of the world's oldest and most well-known biological drugs, and the need for it is not going to go away as the number of patients diagnosed with diabetes continues to increase. A wealth of clinical evidence shows that good, long-term glucose control in diabetes is key to avoiding complications such as kidney disease, blindness and heart problems.

The blood–brain barrier (BBB) forms an interface between the circulating blood and the brain, and functions as a tremendously effective barrier for the delivery of potential neurotherapeutics into the brain parenchyma. Conversely, the BBB possesses various carrier-mediated transport systems for the uptake of small molecules, such as essential nutrients and vitamins. These transporters have become an attractive target for drug/prodrug design in an attempt to ferry drug molecules across the BBB. Central nervous system (CNS) drug delivery is often limited by poor brain penetration of the potential drug candidate. As a result of its unique barrier properties, the BBB poses a huge challenge for the delivery of potential neurotherapeutics into the brain parenchyma.1 It is estimated that only 2% of small-molecule drugs and ,0.1% of novel protein and peptide pharmaceuticals developed for CNS diseases reach therapeutic concentrations in the brain.2,3 Many of the pharmacologically active drugs tend to fail..
