What is Aminopyrine and Antipyrine?

What is Aminopyrine and Antipyrine?

Aminopyrine (amidopyrine or dimethylaminoantipyrine) and antipyrine (phenazone) are pyrazolone derivates used in the past as antipyretics. The two drugs probe similar, but not equal, isozymes of cytochrome P-450, and they have similar prognostic value in clinical practice.

What is the role of 4 Aminoantipyrine?

4-aminoantipyrine is the most widely used analytical reagent for the estimation of phenol. Phenolic compounds were determined by buffering the sample to a pH of 10.0 and adding 4-aminoantipyrine to produce a yellow or amber colored complex in the presence of ferricyanide ion.

What is Aminophenazone used for?

Aminophenazone is an analgesic drug used to treat acute migraine attacks in combination with ergotamine and caffeine. Aminophenazone is a pyrazolone with analgesic, anti-inflammatory, and antipyretic properties that carries a risk of agranulocytosis.

What is Pyramidon used for?

Aminophenazone (or aminopyrine, amidopyrine, Pyramidon) is a non-narcotic analgesic substance. It is a pyrazolone, which also anti-inflammatory, and antipyretic properties.

What is the aminopyrine breath test?

The aminopyrine breath test, like other newer tests (phenacetin, caffeine and erythromycin breath tests), allows the effects of drugs on hepatic cytochrome P-450 to be explored both in normal subjects and in liver patients.

How are barbiturates classified?

Barbiturates are classified as Schedule II substances, meaning the have definite potential for physical and psychological dependence and abuse. Barbiturates may be habit-forming. Tolerance, psychological dependence, and physical dependence may occur especially following prolonged use of high doses of barbiturates.

What is the Colour of 4 Aminophenazone?

purple dye
2.1 Photometric enzymatic methods The enzyme glucose oxidase converts glucose into gluconic acid and hydrogen peroxide. Then the peroxidase catalyzes a chromogenic reaction of phenol with 4-aminoantipyrine to a purple dye.

What was used as antipyretic drug?

ANTIPYRETICS. A wide variety of antipyretic agents is available. In the United States, the drugs used most frequently for treatment of fever in children are acetaminophen and ibuprofen. Previously, aspirin was the antipyretic used most frequently.

Are barbiturates acidic or basic?

Long-acting barbiturates such as phenobarbital have continued to be used as anticonvulsants and have the least potential for abuse (Table 1). Barbiturates are administered orally or parenterally. As weak acids, they are absorbed rapidly from the stomach and small intestine into the systemic circulation.

What is the difference between barbiturates and non barbiturates?

Barbiturates are CNS depressant drugs possessing the barbituric acid ring structure. Nonbarbiturates are hypnotic drugs that do not possess the barbituric acid ring structure.

What is the best antipyretic?

Acetaminophen (AA), the first antipyretic used in modern medicine, and ibuprofen have been the most widely used antipyretics, However the more recently developed dexibuprofen (DEX) series has become common in recent years. AA is recommended at doses of 10–15 mg/kg and should be administered orally once every 4 hours.

Which type of drugs reduces fever?

Is indomethacin acidic or basic?

Indomethacin has a pKa of 4.5 and is stable in neutral or slightly acidic media and decomposes in strong alkali. The suspension has a pH of 4.0-5.0.

Which ring is present in phenylbutazone?

Phenylbutazone is a member of the class of pyrazolidines that is 1,2-diphenylpyrazolidine-3,5-dione carrying a butyl group at the 4-position. It has a role as a non-narcotic analgesic, a non-steroidal anti-inflammatory drug, an antirheumatic drug, a peripheral nervous system drug, a metabolite and an EC 1.1.

What are barbiturates?

Barbiturates are a group of drugs in the class of drugs known as sedative-hypnotics, which generally describes their sleep-inducing and anxiety-decreasing effects. Barbiturates can be extremely dangerous because the correct dose is difficult to predict. Even a slight overdose can cause coma or death.

What is the difference between barbiturates and benzodiazepines?

The primary difference between the two is that benzodiazepines do not stimulate the GABA receptor directly, they simply make GABA receptors more efficient. Benzodiazepines still produce a calming effect but don’t have as depressive an effect on the central nervous system as barbiturates do.
