Esomeprazole is a proton pump inhibitor which is used in the treatment of dyspepsia, peptic ulcer disease, gastroesophageal reflux disease and Zollinger-Ellison syndrome. It is the S-enantiomer of omeprazole. It is a proton pump inhibitor which reduces acid secretion through inhibition of ATPase in gastric parietal cells.Esomeprazole is combined with the antibiotics clarithromycin and amoxicillin in the 7-14 day eradication triple therapy for Helicobacter pylori.

Esreboxetine is a selective norepinephrine reuptake inhibitor which was under development by Pfizer for the treatment of neuropathic pain and fibromyalgia but failed to show significant benefit over currently available medications and was discontinued. It is the (+)-(S,S)-enantiomer of reboxetine and is even more selective in comparison.

Famprofazone is a non-steroidal anti-inflammatory agent of the pyrazolone series. It has analgesic, anti-inflammatory, and antipyretic effects. It has been known to produce methamphetamine as an active metabolite, with 15-20% of an oral dose being converted to it. As a result, famprofazone has occasionally been implicated in causing false positives on drug tests for amphetamines.

Fast Red ITR

Fast Red ITR can be used as pharmaceutical intermediates and hair dye intermediate. It can also be used in semi-permanent&permanent hair colors for cosmetic.

Fenbutrazate is a psychostimulant used as an appetite suppressant. It is a derivative of phenmetrazine and may function as a prodrug to it similarly to phendimetrazine.


Fenfluramine is a drug that was part of the Fen-Phen anti-obesity medication. It was introduced on the U.S. market in 1973. It is the racemic mixture of two enantiomers, dextrofenfluramine and levofenfluramine. It increases the level of the neurotransmitter serotonin, a chemical that regulates mood, appetite and other functions. It causes the release of serotonin by disrupting vesicular storage of the neurotransmitter, and reversing serotonin transporter function. The end result is a feeling of fullness and loss of appetite. The drug was withdrawn from the U.S. market in 1997 after reports of heart valve disease, and pulmonary hypertension, including a condition known as cardiac fibrosis. After the US withdrawal of fenfluramine, it was also withdrawn from other markets around the world.


Fenpentadiol is a drug formerly used as an antidepressant in Europe. It also has stimulant, sedative, and anxiolytic effects, with the latter two occurring only at higher doses. Its mechanism of action has never been determined but it has been suggested that it may act as a dopamine reuptake inhibitor and GABAergic.

Ferric Oxide

Ferric oxide is an inorganic compound. It is used as the feedstock of the steel and iron industries. It is used to put the final polish on metallic jewellery and lenses, and historically as a cosmetic. It is also used as a pigment. Nanoparticles of ferric oxide are biocompatible, non-toxic, are chemically active on their surface, and are paramagnetic at particle sizes above a critical limit of about 5 nanometers. They find wide use in biomedical applications. Can be used as contrast agents in magnetic resonance imaging, in labeling of cancerous tissues, magnetically controlled transport of pharmaceuticals, localized thermotherapy, and preparation of ferrofluids. Ferric oxide in a granular form is readily available for purchase in the saltwater aquarium and reef community. Its primary function as a filtration media is to pull phosphates out of the water column to aid in the control of nuisance algae.

Fexofenadine is an antihistamine pharmaceutical drug used in the treatment of hayfever, allergy symptoms, and urticaria. It was developed as a successor of and alternative to terfenadine and an antihistamine that caused QT interval prolongation, potentially leading to cardiac arrhythmia. Fexofenadine, like other second- and third-generation antihistamines, does not readily cross the blood-brain barrier, and so causes less drowsiness than first-generation histamine-receptor antagonists. It works by being an antagonist to the H1 receptor.
