Properties of Solid System in Pharmaceutical Dosage Forms

Tablets and capsules are the most common type of solid dosage form used in pharmaceuticals.

Solid dosage forms, like tablets and capsules, don't need preservatives to prevent bacteria growth.

Solid dosage forms are less susceptible to microbial contamination compared to liquid dosage forms.

Over half of all approved medicines are taken orally as solid dosage forms.

Tablets and capsules are easy and convenient for patients to take.

Powdered drugs are the least common type of solid dosage form used today.

Particle size is a measure of the surface area and projected areas of a solid particle.

Asymmetric particles have a larger surface area per unit volume than spherical particles.

The equivalent spherical diameter is used to approximate the size of irregular particles as if they were spheres.

Stoke's diameter describes the size of an imaginary sphere that would settle at the same rate as an asymmetric particle.

Mouth dissolving tablets, also known as orally disintegrating tablets, dissolve in the mouth without the need for water.

Enteric coated tablets are designed to resist stomach acid and release the drug in the small intestine.
