Pharmaceutical formulation, in pharmaceutics, is the process in which the active drug or Active Pharmaceutical Ingredient (API) is combined with different chemical substances to produce a final medicinal product. The word formulation is often used in a way that includes dosage form.
Taxanes are a class of diterpenes. They were originally identified from plants of the genus Taxus (yews), and feature a taxadiene core. Paclitaxel (Taxol) and docetaxel (Taxotere) are widely used as chemotherapy agents. Cabazitaxel was FDA approved to treat hormone-refractory prostate cancer.
Taxanes present difficulties in formulation as medicines because they are poorly soluble in water.
Glycerol (/ˈɡlɪsərɒl/) is an organic compound with chemical formula C3H5(OH)3. It has a three-carbon backbone and is a simple triol compound (an alcohol with three hydroxyl groups). It is a colorless, odorless, sweet-tasting, viscous liquid. Because of its three hydroxyl groups, glycerol is miscible with water and is hygroscopic in nature.
The glycerol backbone is found in lipids known as glycerides, where one or more of the hydroxyl groups are esterified with fatty acids. The most abundant of glycerides are triglycerides (found in animal fats and vegetable oils), it is where glycerol is most commonly found in nature. It is also widely used as a sweetener in the food industry and as a humectant in pharmaceutical formulations.
In a general sense, an ingredient is a substance which forms part of a mixture. In cooking, recipes specify which ingredients are used to prepare a dish, and the term may also refer to a specific food item in relation to its use in different recipes. Many commercial products contain secret ingredients purported to make them better than competing products. In the pharmaceutical industry, an active ingredient is the ingredient in a formulation which invokes biological activity.
National laws usually require prepared food products to display a list of ingredients and specifically require that certain additives be listed. Law typically requires that ingredients be listed according to their relative weight within the product.

National laws usually require prepared food products to display a list of ingredients and specifically require that certain additives be listed. In the European Union, food labeling regulations also mandate that allergens such as nuts, milk, and gluten be clearly emphasized within the ingredient list to protect consumers.
A generic drug is a pharmaceutical drug that contains the same chemical substance as a proprietary drug that was originally protected by chemical patents. Generic drugs are allowed for sale after the patents on the original drugs expire. Because the active chemical substance is the same, the medical profile of generics is equivalent in performance compared to their performance at the time when they were patented drugs. A generic drug has the same active pharmaceutical ingredient (API) as the original, but it may differ in some characteristics such as the manufacturing process, formulation, excipients, color, taste, and packaging.
Although they may not be associated with a particular company, generic drugs are usually subject to government regulations in the countries in which they are dispensed. They are labeled with the name of the manufacturer and a generic non-proprietary name such as the United States Adopted Name (USAN) or International Nonproprietary Name (INN) of the drug. A generic drug must contain the same active ingredients as the original brand-name formulation. The U.S. Food and Drug Administration (FDA) requires generics to be identical to or within an acceptable bioequivalent range of their brand-name counterparts, with respect to pharmacokinetic and pharmacodynamic properties.
Lipid-based nanoparticles are very small spherical particles composed of lipids. They are a novel pharmaceutical drug delivery system (part of nanoparticle drug delivery), and a novel pharmaceutical formulation. There are many subclasses of lipid-based nanoparticles such as: lipid nanoparticles (LNPs), solid lipid nanoparticles (SLNs), and nanostructured lipid carriers (NLCs).
Sometimes the term "LNP" describes all lipid-based nanoparticles. In specific applications, LNPs describe a specific type of lipid-based nanoparticle, such as the LNPs used for the mRNA vaccine.
Glycerol (/ˈɡlɪsərɒl/) is a sugar alcohol with chemical formula C3H5(OH)3. It has three carbon atoms and as many hydroxyl groups. It is a colorless, odorless, sweet-tasting, viscous liquid at Standard Ambient Temperature and Pressure (SATP). Because of its three hydroxyl groups, glycerol is miscible with water and is hygroscopic in nature.
The glycerol backbone is found in lipids known as glycerides, where one or more of the hydroxyl groups are esterified with fatty acids. The most abundant of glycerides are triglycerides (found in animal fats and vegetable oils), it is where glycerol is most commonly found in nature. It is also widely used as a sweetener in the food industry and as a humectant in pharmaceutical formulations.
