Final answer:
The listing of a medication in two different forms suggests variations in dosage and route of administration. Proper dosage depends on factors such as patient characteristics and drug properties to achieve therapeutic effects without causing toxicity.
Step-by-step explanation:
If you notice that a medication is listed with two different forms, it typically means that the medication can be administered via different routes of administration or it may come in different dosages. The form of medication refers to its physical presentation (e.g., tablet, capsule, liquid) and route of administration is how the drug is to be given (e.g., oral, intravenous, intramuscular). Different forms can affect the dosage and how quickly or effectively the drug acts in the body.
When determining the appropriate dosage of a medication, several factors must be considered including the patient's age, mass, liver and kidney function, and the drug's half-life. This ensures that therapeutic drug levels are achieved without causing significant toxicity. Some drugs, for example, are more effective if maintained at optimum levels over time (time dependent), while others work better in high concentrations over a short duration (dose dependent).
