An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]
Given a dose of an opioid, an equianalgesic table is used to find the equivalent dosage of another. Such tables are used in opioid rotation practices, and to describe an opioid by comparison to morphine, the reference opioid. Equianalgesic tables typically list drug half-lives, and sometimes equianalgesic doses of the same drug by means of ...

A chart outlining the structural features that define opiates and opioids, including distinctions between semi-synthetic and fully synthetic opioid structures. An opiate is an alkaloid substance derived from opium (or poppy straw). [1]
Carbonate derivatives of 14β-hydroxycodeine "viz., 14β-hydroxy-6-O-(methoxycarbonyl)codeine, 6-O-methoxycarbonyl-14β-(methoxycarbonyloxy)codeine, and 14β-acetoxy-6-O-methoxy-carbonylcodeine, potential substrates for ring C modification in morphinane (sic) alkaloids, were synthesized for the first time."
Considered a low-to-medium-potency opioid, tilidine has the oral potency of about 0.2, that is, a dose of 100 mg p.o. is equianalgesic to approximately 20 mg morphine sulfate orally. It is administered orally (by mouth), rectally (by a suppository ), or by injection (SC, IM, or slowly IV).

Morphine is effective and relatively safe, and is often used with moderate to severe pain. [19] Codeine and tramadol should be avoided especially in children younger than 12 years old since metabolism varies due to genetic differences between individuals, [20] and, in the case of tramadol, this medication has not been well studied in children.
