What are pharmaceutical excipients?

Pharmaceutical excipients are substances other than the pharmacologically active drug or prodrug which are included in the manufacturing process or are contained in a finished pharmaceutical product dosage form.

What makes Neusilin® a suitable carrier for solid dispersions?

Superior drug loading capacity, flow index, compressibility index, larger surface area, higher adsorption capacity of oily APIs/surfactants and ability to protect the drug from deliquescence are important characters that make Neusilin® a suitable carrier for solid dispersion.

What is the pore size/distribution (in nm) for Neusilin® US2? Are the diameters and length of these pores known?

The average pore size of Neusilin® US2 is around 15nm in diameter. There are no defined lengths for these pores as Neusilin® is an amorphous compound.

What excipient functions can be attributed to Neusilin®?

Neusilin® is a multifunctional excipient. It is an excellent binder, diluent, compression aid, dispersing agent and a disintegration aid.

Although Neusilin® UFL2 is a powder, how does it improve flowability?

Low amount of Neusilin® UFL2 disperse homogenously over the surface of various types of powder particles preventing particle-particle adhesion and acts as a roller blade. Neusilin® UFL2 also prevents deliquescence of tablets.

How stable is Neusilin® against heat?

Neusilin® is stable up to 700°C.

Does Neusilin® becomes gel on absorbing water?

No. Neusilin® does not become gels on contact with water. Neusilin® a totally synthetic and does not dissolve in water or ethanol.

Can Neusilin® be used for both direct compression and wet granulation?

Yes. Neusilin® can be used for both direct compression and wet granulation without any problem.
