Pharmacy

Derived from the Greek word Pharmakon (meaning a drug or biologically active substance), it is the art and science of preparing and dispensing medications and providing drug-related information to the public.

Drug (FDA Definition)

A substance intended for use in the diagnosis, cure, treatment, or prevention of disease.

Active Pharmaceutical Ingredient (API)

The biologically active constituent or pure chemical in a medicine responsible for producing the desired pharmacological effect.

Excipients

Additives combined with the active pharmaceutical ingredient that serve specialized functions such as solubilizing, suspending, preserving, emulsifying, and improving compressibility or flavor to create the final dosage form.

Pharmaceutics

The science of converting a pure 'drug' into a finished 'medicine' through dosage form design to achieve predictable therapeutic responses with reproducible quality.

Capsule

A solid unit dosage form derived from the Latin 'capsula' ('small box'), where the drug substance is enclosed in a soluble shell made of hydrolyzed collagen gelatin.

Hard Gelatin Capsule vs. Soft Gelatin Capsule

Hard gelatin capsules consist of a two-piece shell (body and cap) manufactured first and filled separately with dry powders, granules, or pellets. Soft gelatin capsules consist of a flexible, one-piece shell containing plasticizers (like glycerin) that is formed, filled with liquids/pastes, and hermetically sealed in a single continuous process.

Suppository

A solid dosage form intended for insertion into the rectum for local or systemic therapeutic effect, formulated with a fatty base (e.g., cocoa butter that melts at body temperature) or a gelatoglycerin base (which dissolves inside the cavity).

Pessary

A solid pharmaceutical dosage form intended specifically for insertion into the vaginal cavity to exert local or systemic action.

Ointment

A greasy semisolid preparation that forms an occlusive barrier over the skin surface to soften tissues and retain moisture.

Paste

A stiff, thick semisolid preparation containing a high proportion of insoluble solid powders that provides protective and absorptive qualities.

Cream

A semisolid emulsion ($\text{o/w}$ or $\text{w/o}$) that is non-greasy, spreads easily on the skin, and washes off readily compared to ointments.

Gel

A transparent or translucent semisolid dosage form consisting of a water- or alcohol-based network that spreads rapidly and is non-greasy.

Transdermal Patch

A medicated adhesive device applied directly to unbroken skin designed to release drug at a controlled rate into the systemic bloodstream over hours to days.

Inhaler

A device engineered to deliver micronized powder particles or fine aerosol droplets into the respiratory tract for localized pulmonary action or systemic delivery.

Parenteral Dosage Form

A sterile solution, suspension, or emulsion administered via injection (e.g., intravenous for immediate onset, or intramuscular/subcutaneous for depot action) that completely bypasses the gastrointestinal tract.

Primary Literature

Original scientific research articles published in peer-reviewed journals containing novel experimental data structured into title, abstract, introduction, methodology/results, discussion, and references.

Secondary Literature

Publications that summarize, review, and compile established medical data, including review articles and standard reference textbooks.

Tertiary Literature
