Study Notes

Tablet Types and Characteristics

Orally disintegrating tablets (ODTs) are designed to provide rapid disintegration and rapid drug release.
Conventional compressed tablets are characterized by rapid release of the active ingredient.
Modified-release tablets are designed to release drug slowly and continuously over an extended period of time.

Tablet Design and Function

The indentation running down the middle of many caplets is called a "break-line" or "score line", which facilitates easy breaking of the tablet into two halves.
Multiple compressed tablets offer the advantage of flexibility in dosage adjustment.

Quality Attributes and Textbook

The quality attributes of tablets mentioned in the text are: strength, uniformity, and purity.
The recommended textbook for this course is not specified.
By the end of the course, the student should be able to design, prepare, and evaluate solid dosage forms.

Tablet Definition and Function

According to the European Pharmacopoeia (5th edition, 2005), tablets are defined as "solid preparations with or without coatings, consisting of a mixture of active substances and excipients, usually in a specific ratio, which are obtained by compressing the mixture".
The original definition of a pill is a small, round, solid dosage form, made from a mixture of active ingredients and excipients.
The primary function of excipients in tablet formulation is to enhance the performance of the active ingredient.

Solid Dosage Forms

The main difference between powders and granules in the context of solid dosage forms is that granules are aggregated powders with a larger particle size.
The main disadvantage of tablets as a dosage form is that they can be difficult to swallow, especially for pediatric and geriatric patients.
Bioavailability is a crucial factor in modifying the bioavailability of drugs from different dosage forms.
