Which has more opioids in it propacet 100 or percocet 10?


Propacet 100 contains 100 mg of propoxyphene. Percocet 10 contains 10 mg of oxycodone. Both of these ingredients are narcotics. Propoxyphene is weaker than oxycodone, so the two are probably similar in strength based on the mg per dose.

Dextropropoxyphene is an analgesic in the opioid category, patented (1955) and manufactured by Eli Lilly and Company. It is intended to treat mild pain and also has antitussive and local anaesthetic effects. The drug has been taken off the market in Europe and the US due to concerns of fatal overdoses and heart arrhythmias. An estimated 10 million patients have used these products.

The combination oxycodone/paracetamol (North American trade name Percocet, generic endocet and ratio-oxycocet in Canada) is a narcotic pain reliever used to treat moderate to severe acute (short-term) pain, marketed by Endo Pharmaceuticals. It is regulated as a schedule 2 narcotic by the Drug Enforcement Agency (DEA) of the United States.

The U.S. Food and Drug Administration first approved Percocet in 1976, under application ANDA 085106.




A combination drug most commonly refers to a fixed-dose combination (FDC), which is a formulation including two or more active pharmaceutical ingredients (APIs) combined in a single dosage form, which is manufactured and distributed in certain respective fixed doses. Terms like "combination drug" or "combination drug product" can be common shorthand for a FDC product (since most combination drug products are currently FDCs), although the latter is more precise if in fact referring to a mass-produced product having a predetermined combination of drugs and respective dosages (as opposed to customized polypharmacy via compounding). And it should also be distinguished from the term "combination product" in medical contexts, which without further specification can refer to products that combine different types of medical products - such as device/drug combinations as opposed to drug/drug combinations. Note that when a combination drug product (whether fixed-dose or not) is a "pill" (i.e., a tablet or capsule), then it is also a kind of "polypill" or combopill.

Initially, fixed-dose combination drug products were developed to target a single disease (such as with antiretroviral FDCs used against AIDS). However, FDCs may also target multiple diseases/conditions, such as Caduet (atorvastatin/amlodipine) or Exforge (amlodipine/valsartan). In cases of FDCs targeting multiple conditions, such conditions might often be related — in order to increase the number of prospective patients who might be likely to utilize a given FDC product. This is because each FDC product is mass-produced, and thus typically requires having a critical mass of potentially applicable patients in order to justify its manufacture, distribution, stocking, etc.


An analgesic, or painkiller, is any member of the group of drugs used to achieve analgesia — relief from pain. The word analgesic derives from Greek αν – ("without") and άλγος – ("pain").

Analgesic drugs act in various ways on the peripheral and central nervous systems. They are distinct from anesthetics, which reversibly eliminate sensation, and include paracetamol (known in the US as acetaminophen or simply APAP), the non-steroidal anti-inflammatory drugs (NSAIDs) such as the salicylates, and opioid drugs such as morphine and opium.


In chemistry, an alcohol is an organic compound in which the hydroxyl functional group (-OH) is bound to a carbon atom. In particular, this carbon center should be saturated, having single bonds to three other atoms.

An important class of alcohols are the simple acyclic alcohols, the general formula for which is CnH2n+1OH. Of those, ethanol (C2H5OH) is the type of alcohol found in alcoholic beverages, and in common speech the word alcohol refers specifically to ethanol.


In chemistry, a ketone (Alkanone) /ˈktn/ is an organic compound with the structure RC(=O)R', where R and R' can be a variety of carbon-containing substituents. Ketones feature a carbonyl group (C=O) bonded to two other carbon atoms. Many ketones are known and many are of great importance in industry and in biology. Examples include many sugars (ketoses) and the industrial solvent acetone.

The word ketone derives its name from Aketon, an old German word for acetone.



Oxycodone is a semi-synthetic opioid synthesized from poppy-derived thebaine. It is a narcotic analgesic generally indicated for relief of moderate to severe pain. It was developed in 1916 in Germany as one of several new semi-synthetic opioids in an attempt to improve on the existing opioids.



Paracetamol INN (/ˌpærəˈstəmɒl/ or /ˌpærəˈsɛtəmɒl/), or acetaminophen USAN Listeni/əˌstəˈmɪnəfɨn/, chemically named N-acetyl-p-aminophenol, is a widely used over-the-counter analgesic (pain reliever) and antipyretic (fever reducer).


An opioid is any psychoactive chemical that resembles morphine or other opiates in its pharmacological effects. Opioids work by binding to opioid receptors, which are found principally in the central and peripheral nervous system and the gastrointestinal tract. The receptors in these organ systems mediate both the beneficial effects and the side effects of opioids.

Although the term opiate is often used as a synonym for opioid, the term opiate is properly limited to the natural alkaloids found in the resin of the opium poppy (Papaver somniferum), while opioid refers to both opiates and synthetic substances, as well as to opioid peptides.


Chemistry, a branch of physical science, is the study of the composition, properties and behavior of matter. Chemistry is chiefly concerned with atoms and their interactions with other atoms - for example, the properties of the chemical bonds formed between atoms to create chemical compounds. As well as this, interactions including atoms and other phenomena - electrons and various forms of energy - are considered, such as photochemical reactions, oxidation-reduction reactions, changes in phases of matter, and separation of mixtures. Finally, properties of matter such as alloys or polymers are considered.

Chemistry is sometimes called "the central science" because it bridges other natural sciences like physics, geology and biology with each other. Chemistry is a branch of physical science but distinct from physics.

Organic chemistry

Organic chemistry is a chemistry subdiscipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. Study of structure includes using spectroscopy and other physical and chemical methods to determine the chemical composition and constitution of organic compounds and materials. Study of properties includes both physical properties and chemical properties, and uses similar methods as well as methods to evaluate chemical reactivity, with the aim to understand the behavior of the organic matter in its pure form (when possible), but also in solutions, mixtures, and fabricated forms. The study of organic reactions includes both their preparation—by synthesis or by other means—as well as their subsequent reactivities, both in the laboratory and via theoretical (in silico) study.

The range of chemicals studied in organic chemistry include hydrocarbons, compounds containing only carbon and hydrogen, as well as compositions based on carbon but containing other elements. Organic chemistry overlaps with many areas including medicinal chemistry, biochemistry, organometallic chemistry, and polymer chemistry, as well as many aspects of materials science.


Science of drugs including their origin, composition, pharmacokinetics,
pharmacodynamics, therapeutic use, and toxicology.

Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
