Pharmaceutics II Exam 2 Concepts Practice Test

Oral tinctures are concentrated plant extracts used in small, adjustable volumes, and dosing is traditionally given in drops because a drop is a practical unit for adjusting potency. A typical drop is about 0.05 mL, so 10–40 drops correspond to roughly 0.5–2 mL. This range is broad enough to accommodate different tincture strengths and patient needs while staying within a practical, commonly used starting dose for adults. Smaller amounts like 1–5 drops are usually for especially potent tinctures or for testing tolerance, while larger ranges such as 50–100 drops (about 2.5–5 mL) or 2–5 mL can be higher than the general dosing for many preparations. Thus, 10–40 drops represents the standard general dosing for adults.
