CHEMICAL (ABSOLUTE)



Dextromethorphan is a non-narcotic morphine derivative widely used as an antitussive for almost 40 years. It has attracted attention due to its anticonvulsant and neuroprotective properties. It is a cough suppressant in many over-the-counter cold and cough medicines. In 2010, the FDA approved the combination product dextromethorphan/quinidine for the treatment of pseudobulbar affect. Dextromethorphan suppresses the cough reflex by a direct action on the cough center in the medulla of the brain. Dextromethorphan shows high-affinity binding to several regions of the brain, including the medullary cough center. This compound is an NMDA receptor antagonist and acts as a non-competitive channel blocker. It is one of the widely used antitussives and is used to study the involvement of glutamate receptors in neurotoxicity. Dextromethorphan (DM) is a sigma-1 receptor agonist and an uncompetitive NMDA receptor antagonist. The mechanism by which dextromethorphan exerts therapeutic effects in patients with pseudobulbar affect is unknown. Dextromethorphan should not be taken with monoamine oxidase inhibitors due to the potential for serotonin syndrome. Dextromethorphan is extensively metabolized by CYP2D6 to dextrorphan, which is rapidly glucuronidated and unable to cross the blood-brain barrier.

21 CFR 341.14(a)(2)(ii) cough/cold:antitussive codeine phosphate

First marketed in 1921

Codeine Sulphate U.S.P.
Source URL:

Class (Stereo):
CHEMICAL (ABSOLUTE)


Conditions:

Codeine is an opiate used to manage mild to moderate pain severe enough to require an opioid. Codeine is a selective agonist for the mu opioid receptor and has an affinity to delta and kappa-opioid receptors. In some countries, this drug is regulated under various narcotic control laws, because its chronic use can cause physical dependence. In others, it is available without a medical prescription in combination with paracetamol.

INN:desmetramadol [INN]
Source URL:

Class (Stereo):
CHEMICAL (RACEMIC)

O-Desmethyl tramadol (O-Desmethyltramadol, O-DSMT) is a metabolite of tramadol. O-Desmethyltramadol is an opioid analgesic and the main active metabolite of tramadol. (+)-O-Desmethyltramadol is the most important metabolite of tramadol produced in the liver after tramadol is consumed. This metabolite is considerably more potent as a μ-opioid agonist than the parent compound. O-desmethyl tramadol, inhibits 5-hydroxytryptamine type 2C receptors expressed in xenopus oocytes. O-desmethyl tramadol inhibits functions of M(1) receptors but has little effect on those of M(3) receptors. O-desmethyl tramadol has been widely used clinically and has analgesic activity.

INN:norcodeine [INN]
Source URL:

Class (Stereo):
CHEMICAL (ABSOLUTE)


Conditions:

Norcodeine is the N-demethylated derivative of codeine. It has relatively little opioid activity in its own right, but is formed as a metabolite of codeine following ingestion. Codeine and its other major metabolites codeine-6-glucuronide and norcodeine have weak affinity to opioid μ-receptors.

INN:phenampromide [INN]
Source URL:

Class (Stereo):
CHEMICAL (RACEMIC)

Phenampromide is an opioid analgesic, which is considered to be structurally similar to isomethadone. Phenampromide belongs to the ampromide family of drugs, which also include propiram and diampromide. According to the literature, (R)-phenampromide has greater analgesic potency than its (S)-enantiomer. Synthetic narcotic analgesic phenampromide is under international control according to the UN Single Convention 1961 and its amendments, Schedule I.

INN:nicodicodine
Source URL:

Class (Stereo):
CHEMICAL (ABSOLUTE)

Nicodicodine is a cough suppressant and analgesic. It was first synthesized in 1904. It is a Schedule III drug. Nicodicodine is metabolised in the liver to dihydromorphine. Since the final active metabolite is the slightly stronger opiate than morphine, nicodicodine can be expected to be more potent and longer acting than nicocodeine.
