Sodium Salt
Sodium salts are salt (chemistry), salts composed of a sodium cation and the conjugate base anion of some Inorganic compound, inorganic or Organic compound, organic acids. They can be formed by the Neutralization (chemistry), neutralization of such acids with sodium hydroxide. Categorization Sodium salts can be categorized into: *sodium salts of carboxylic acids (e. g. sodium formate, HCOONa, the sodium salt of formic acid or sodium acetate, CH3COONa, the sodium salt of acetic acid, etc.) and *sodium salts of inorganic acids (Sulfonic acid, sulfonic acids etc.) Organic sodium salts Drugs In pharmaceutical technology acidic pharmaceutical substances are often converted into sodium salts, because they are more stable, more soluble or membrane-permeable (bioavailable) than the base compound. Examples of such sodium salts are (selection): Bispyribac, bithionol, bosentan, brequinar, bromfenac, Cefmenoxime, ceftiofur, citicoline, diclofenac , Flucloxacillin, Floxacillin, fosinopril ...

Salt (chemistry)
In chemistry, a salt is a chemical compound consisting of an ionic assembly of positively charged cations and negatively charged anions, which results in a compound with no net electric charge. A common example is table salt, with positively charged sodium ions and negatively charged chloride ions. The component ions in a salt compound can be either inorganic, such as chloride (Cl−), or organic, such as acetate (). Each ion can be either monatomic, such as fluoride (F−), or polyatomic, such as sulfate (). Types of salt Salts can be classified in a variety of ways. Salts that produce hydroxide ions when dissolved in water are called ''alkali salts'' and salts that produce hydrogen ions when dissolved in water are called ''acid salts''. ''Neutral salts'' are those salts that are neither acidic nor basic. Zwitterions contain an anionic and a cationic centre in the same molecule, but are not considered salts. Examples of zwitterions are amino acids, many metabolites, peptid ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Citicoline
Citicoline (INN), also known as cytidine diphosphate-choline (CDP-Choline) or cytidine 5'-diphosphocholine is an intermediate in the generation of phosphatidylcholine from choline, a common biochemical process in cell membranes. Citicoline is naturally occurring in the cells of human and animal tissue, in particular the organs. Use as a dietary supplement Citicoline is available as a supplement in over 70 countries under a variety of brand names: Cebroton, Ceraxon, Cidilin, Citifar, Cognizin, Difosfocin, Hipercol, NeurAxon, Nicholin, Sinkron, Somazina, Synapsine, Startonyl, Trausan, Xerenoos, etc. When taken as a supplement, citicoline is hydrolyzed into choline and cytidine in the intestine. Once these cross the blood–brain barrier it is reformed into citicoline by the rate-limiting enzyme in phosphatidylcholine synthesis, CTP-phosphocholine cytidylyltransferase. Research Memory and cognition Studies have failed to confirm any potential benefits of citicoline for cognitive imp ...

Bromfenac
Bromfenac is a nonsteroidal anti-inflammatory drug (NSAID) marketed in the US as an ophthalmic solution (brand names Prolensa and Bromday, prior formulation brand name Xibrom, which has since been discontinued) by ISTA Pharmaceuticals for short-term, local use. Prolensa and Bromday are the once-daily formulation of bromfenac, while Xibrom was approved for twice-daily administration. In the European Union, the brand name is Yellox. Bromfenac is indicated for the treatment of ocular inflammation and pain after cataract surgery. Medical uses Bromfenac is indicated for the treatment of postoperative ocular inflammation following cataract extraction. The drug has been shown to reduce macular edema and thickness of the retina (an indicator for inflammation) and improve visual acuity after surgery. Contraindications Bromfenac is contraindicated for people with adverse reactions to NSAIDs, such as asthma or rashes. Side effects Bromfenac eye drops are generally well tolerate ...

Bosentan
Bosentan, sold under the brand name Tracleer and Safebo among others, is a dual endothelin receptor antagonist medication used in the treatment of pulmonary artery hypertension (PAH). Bosentan is available as film-coated tablets (62.5 mg or 125 mg) or as dispersable tablets for oral suspension (32 mg). Medical uses Bosentan is used to treat people with moderate pulmonary arterial hypertension and to reduce the number of digital ulcers — open wounds on especially on fingertips and less commonly the knuckles — in people with systemic scleroderma. Bosentan causes harm to fetuses and pregnant women must not take it, and women must not become pregnant while taking it (Pregnancy Category X). It may render hormonal contraceptives ineffective so other forms of birth control must be used. In the US it is only available from doctors who follow an FDA-mandated risk evaluation and mitigation strategy (REMS) with respect to risks to fetuses and its risks of causing liv ...

Bithionol
Bithionol is an antibacterial, anthelmintic, and algaecide. It is used to treat '' Anoplocephala perfoliata'' (tapeworms) in horses and ''Fasciola hepatica'' (liver flukes). __TOC__ Mechanism of action Bithionol has been shown to be a potent inhibitor of soluble adenylyl cyclase, an intracellular enzyme important in the catalysis of adenosine triphosphate (ATP) to cyclic adenosine monophosphate (cAMP). Soluble adenylyl cyclase is uniquely activated by bicarbonate. The cAMP formed by this enzyme is associated with capacitation of sperm, eye pressure regulation, acid-base regulation, and astrocyte/neuron communication. It is related to the organochlorine hexachlorophene, which has been shown to be an isomer-specific inhibitor of soluble adenylyl cyclase. Bithionol has two aromatic rings with a sulfur atom bonded between them and multiple chlorine ions and hydroxyl groups attached to the phenyl groups. These functional groups are capable of hydrophobic, ionic, and polar inter ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bioavailable
In pharmacology, bioavailability is a subcategory of absorption and is the fraction (%) of an administered drug that reaches the systemic circulation. By definition, when a medication is administered intravenously, its bioavailability is 100%. However, when a medication is administered via routes other than intravenous, its bioavailability is generally lower than that of intravenous due to intestinal endothelium absorption and first-pass metabolism. Thereby, mathematically, bioavailability equals the ratio of comparing the area under the plasma drug concentration curve versus time (AUC) for the extravascular formulation to the AUC for the intravascular formulation. AUC is used because AUC is proportional to the dose that has entered the systemic circulation. Bioavailability of a drug is an average value; to take population variability into account, deviation range is shown as ±. To ensure that the drug taker who has poor absorption is dosed appropriately, the bottom value of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pharmaceutical Technology
Pharmaceutics is the discipline of pharmacy that deals with the process of turning a new chemical entity (NCE) or old drugs into a medication to be used safely and effectively by patients. It is also called the science of dosage form design. There are many chemicals with pharmacological properties, but need special measures to help them achieve therapeutically relevant amounts at their sites of action. Pharmaceutics helps relate the formulation of drugs to their delivery and disposition in the body. Pharmaceutics deals with the formulation of a pure drug substance into a dosage form. Branches of pharmaceutics include: *Pharmaceutical formulation *Pharmaceutical manufacturing *Dispensing pharmacy *Pharmaceutical technology *Physical pharmacy *Pharmaceutical jurisprudence Pure drug substances are usually white crystalline or amorphous powders. Before the advent of medicine as a science, it was common for pharmacists to dispense drugs ''as is''. Most drugs today are administered as p ...
