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.

EMS Pharmacology - FDA Pregnancy Category

The FDA Pregnancy Category system classifies drugs according to their safety for use during pregnancy.

It is a system used by the U.S. Food and Drug Administration (FDA) to categorize the risk of fetal harm associated with the use of medications during pregnancy.

The categories are as follows:

Category A: Adequate and well-controlled studies have failed to demonstrate a risk to the fetus in the first trimester of pregnancy (and there is no evidence of risk in later trimesters).

Category B: Animal reproduction studies have failed to demonstrate a risk to the fetus, but there are no adequate and well-controlled studies in pregnant women.

Category C: Animal reproduction studies have shown adverse effects on the fetus, and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.

Category D: There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, but potential benefits may warrant use of the drug in pregnant women despite potential risks.

Category X: Studies in animals or humans have demonstrated fetal abnormalities, and/or there is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, and the risks involved in use of the drug in pregnant women clearly outweigh potential benefits.

It's worth noting that the FDA has moved away from this system in recent years, and labeling now includes more detailed information about the risks associated with drug use during pregnancy rather than simply assigning a category.

EMS Pharmacology - Aspirin (Acetylsalicylic Acid)

EMS Providers should have knowledge of aspirin administration including, amongst other things, its mechanism of action, the effect, and contraindications 

Here are key points to know:

Indications: Aspirin is commonly used in emergency situations to treat suspected heart attacks (myocardial infarctions). It helps prevent blood clot formation and reduces the risk of further cardiac damage.

Mechanism of Action (MOA): Acetylsalicylic acid is an antiplatelet agent. It works by inhibiting the activity of an enzyme called cyclooxygenase (COX). COX is involved in the production of prostaglandins, which play a role in platelet aggregation (clumping) and vasoconstriction.

Effect: By inhibiting COX, aspirin reduces the formation of thromboxane A2, a substance that promotes platelet aggregation and vasoconstriction. As a result, aspirin makes platelets less sticky and less likely to form blood clots. It primarily affects platelet function and is often used to prevent arterial thrombosis, such as in cases of myocardial infarction (heart attack) or stroke.

Dosage: The recommended dosage of acetylsalicylic acid for suspected heart attacks is typically 4 x 81 mg ‘baby aspirin’. EMTs should follow local protocols and medical direction regarding the specific dosage and formulation used.

Route: Aspirin is usually administered orally, which means EMTs may give the patient chewable or crushed aspirin tablets to be swallowed. It is important to ensure the patient can safely swallow the medication and has no contraindications.

Contraindications: EMTs should be aware of contraindications for aspirin administration, such as a known allergy to aspirin, active bleeding, or a history of gastrointestinal bleeding or ulcers. 

If the patient has any contraindications, aspirin should not be administered, and medical direction should be sought.

Documentation: EMS Providers should document the administration of aspirin, including the dosage, time, and the patient's response. Accurate documentation helps ensure continuity of care and provides important information to healthcare providers, including whether the patient has already taken aspirin.

Communication: EMTs should inform receiving healthcare providers about the administration of aspirin, including the dosage and timing. This helps ensure appropriate follow-up care and treatment continuation.

Remember, EMS Providers should always adhere to their local protocols and receive proper training on aspirin administration. They should work under medical direction and consult with a physician or follow local guidelines when administering aspirin to patients.

EMS Pharmacology - Oxygen

EMS Providers (e.g., EMRs, EMTs, AEMTs, EMT-Is, and Paramedics) should have a thorough understanding of oxygen administration.

Here are some key points they should know:

1. Indications: Oxygen administration is used to treat patients who are experiencing hypoxia (low oxygen levels) or respiratory distress. It is commonly used for conditions such as respiratory failure, asthma, chronic obstructive pulmonary disease (COPD), and cardiac arrest.

2. Delivery Methods: EMS providers should be familiar with various delivery methods for oxygen, including nasal cannula, face mask, non-rebreather mask, and bag-valve-mask (BVM) ventilation. Each method has its own flow rates and indications based on the patient's condition and severity.

3. Flow Rates: EMS providers need to understand the appropriate flow rates of oxygen based on the patient's needs. Flow rates are typically measured in liters per minute (LPM) and can range from 1 to 15 LPM, depending on the delivery method and the patient's condition.

4. Monitoring: EMS providers should continuously monitor the patient's oxygen saturation levels using a pulse oximeter. This helps assess the effectiveness of oxygen therapy and ensures the patient is receiving adequate oxygenation.

5. Safety Precautions: EMS providers should follow safety precautions while handling and administering oxygen. This includes avoiding open flames or sparks in the vicinity, ensuring proper ventilation in enclosed spaces, and being cautious of oxygen toxicity risks with prolonged high-flow oxygen administration.

6. Documentation: EMS providers should document the administration of oxygen, including the delivery method, flow rates, and the patient's response to therapy. Accurate documentation is important for continuity of care and future reference.

Remember, EMS providers should always adhere to their local protocols and receive proper training on oxygen administration to ensure safe and effective use in emergency situations.
