EMS Pharmacology - Common Medication (Rx) Forms

Medications come in various dosage forms, each designed to deliver the medication in a specific way.

Some of the most common Rx dosage forms include:

Tablets and Capsules: These are solid dosage forms that contain the active ingredient(s) along with other inactive ingredients. They are taken orally and come in various shapes, sizes, and colors.

Liquid Solutions and Suspensions: These are liquid dosage forms where the active ingredient(s) are dissolved (solution) or suspended (suspension) in a liquid medium. They are often measured with a dropper or a measuring cup and can be administered orally.

Topical Preparations: These dosage forms are applied externally to the skin or mucous membranes and include creams, ointments, gels, lotions, and patches. They deliver medication locally to the affected area.

Injectables: These are dosage forms that are administered via injection into the body, either subcutaneously (under the skin), intramuscularly (into the muscle), or intravenously (into the vein). They include solutions, suspensions, and emulsions.

Suppositories: These are solid dosage forms that are inserted into the rectum, vagina, or urethra, where they dissolve or melt to release the medication. They are often used when oral administration is not feasible or when rapid absorption is needed.

Nasal Sprays and Inhalers: These are dosage forms designed for administration through the nasal passage or inhalation into the lungs. They deliver medication directly to the respiratory tract and are commonly used for conditions such as asthma or allergies.

Eye Drops and Ear Drops: These are liquid dosage forms administered directly into the eyes or ears. They are used to treat various eye and ear conditions and deliver medication locally to these areas.

Powders for Reconstitution: Some medications are supplied as powders that need to be mixed with a liquid (such as water or saline) before administration. These are often used for oral solutions or suspensions.

The choice of dosage form depends on various factors including the route of administration, the intended site of action, patient preference, and the characteristics of the medication itself.
