Pharmaceutical dosage forms are the various ways in which medications are administered to patients. The choice of dosage form is important for a number of reasons, including:
- Effectiveness:
Different dosage forms release the medication into the body at different
rates and in different locations. This can affect how effective the
medication is.
- Safety:
Some dosage forms are more likely to cause side effects than others.
- Patient
preference: Some patients prefer certain dosage forms to others, such as
tablets over injections.
There are many different ways to classify
pharmaceutical dosage forms, but one of the most common is by route of
administration.
Route of Administration
The route of administration is the way in
which a medication is introduced into the body. The most common routes of
administration are:
- Oral:
Medications are taken by mouth. This is the most common route of
administration because it is convenient and easy for patients to do.
- Parenteral:
Medications are injected into the body. This route of administration is
used for medications that cannot be taken orally, such as insulin.
- Topical:
Medications are applied to the skin or mucous membranes. This route of
administration is used for medications that are meant to act locally, such
as creams and ointments.
- Inhalation:
Medications are inhaled into the lungs. This route of administration is
used for medications that are meant to act in the lungs, such as asthma
inhalers.
Dosage Form Types
Within each route of administration, there are
many different types of dosage forms. Here are some examples:
- Oral:
Tablets, capsules, liquids, suspensions, emulsions, powders, granules.
- Parenteral:
Injections, infusions, implants.
- Topical:
Creams, ointments, gels, lotions, patches.
- Inhalation:
Aerosols, nebulizers, dry powder inhalers.
Other Classification Systems
Pharmaceutical dosage forms can also be
classified by:
- Physical
form: Solid, liquid, semisolid, gas.
- Release
mechanism: Immediate release, sustained release, controlled release.
- Dosage
unit: Single dose, multiple dose.
The choice of dosage form is a complex
decision that must be made on a case-by-case basis. Pharmacists play an
important role in helping patients choose the right dosage form for their
needs.
Here are some additional things to keep in mind about pharmaceutical dosage forms:
- Not

cost of a medication can vary depending on the dosage form.
