Which two tinctures are oral and have antidiarrheal/analgesic properties?

• A. Paregoric and Optimum tincture
• B. Opium tincture and Castor oil tincture
• C. Paregoric and Tincture of Iodine
• D. Opium tincture and Tincture of Benzoin

Answer: (A)

The concept here is that opium-derived tinctures taken by mouth can provide both antidiarrheal and analgesic effects because they deliver morphine-like compounds that act on the body's opioid receptors. Paregoric is camphorated tincture of opium, and opium tincture is the plain opium tincture; both are taken orally and can reduce bowel motility (antidiarrheal) and relieve pain (analgesic) through opioid action. The other tinctures listed do not fit this use: castor oil tincture is a laxative, tincture of iodine is an antiseptic, and tincture of benzoin is mainly a topical resin with no systemic analgesic or antidiarrheal effect.
