Phase 2. Drug is investigated as a treatment
Phase 3. Investigated in large multi-center studies to establish efficacy and safety
What are the related drug groups in Respiratory Care
- Neuromuscular blocking agents
- Antiinfective agents
- Central nervous system agents
- Antiarrhythmic agents
- Antihypertensive and antianginal agents
- Anticoagulant and thrombolytic agents
What’s the difference between prescription drugs and over the counter (OTC) drugs
Prescriptions usually have a higher dosage with a description of how to take it AND must be ordered by a health care worker.
