Opipramol (Insidon, Pramolan, Ensidon, Oprimol) is an antidepressant and anxiolytic used in Germany and other European countries. Although it is a member of the tricyclic antidepressants, opipramol's primary mechanism of action is much different in comparison, it doesn’t represent a tricyclic antidepressant drug as it does not inhibit the neuronal uptake of norepinephrine and/or serotonin. Opipramol also acts as a low to moderate affinity antagonist for the D2, 5-HT2, H1, H2, and muscarinic acetylcholine receptors. H1 and H2 receptor antagonism account for its antihistamine effects, and muscarinic acetylcholine receptor antagonism is responsible for its anticholinergic properties. Opipramol was developed by Schindler and Blattner in 1961. Opipramol is typically used in the treatment of generalized anxiety disorder (GAD) and somatoform disorders. Its anxiolysis becomes prominent after only one to two weeks of chronic administration. Upon first commencing treatment, opipramol is rather sedating in nature due to its antihistamine properties, but this effect becomes less prominent with time. The therapy with Opipramol indicates an additional therapy with neuroleptics, hypnotics and tranquilizers (e.g. Barbiturates, Benzodiazepines). Therefore, it should be noted that some specific reactions, particularly CNS depressant effects could be intensified and an intensification of common side effects may occur. If necessary the dosage may be reduced. Co-administration with alcohol can cause stupor. MAO Inhibitors should be discontinued at least 14 days before the treatment with Opipramol. Concomitant use of Opipramol with β-blockers, antiarrhythmics (of class 1c), as well as drugs from tricyclic antidepressant group and preparations which influence the microsomal enzyme system, can lead to change in plasma concentration of these drugs. Co-administration of neuroleptics (example- haloperidol, risperidone) can increase the plasma concentration.

cis-Dosulepin is a stereoisomer of Dothiepin (trade name Prothiaden, Dothep, Thaden, and Dopress; Dosulepin (INN, BAN) a tricyclic antidepressant that is used in several European and South Asian countries, as well as Australia, South Africa, and New Zealand. Dosulepin is used for the treatment of the major depressive disorder and neuropathic pain. Dosulepin is only Therapeutic Goods Administration and Medicines and Healthcare products Regulatory Agency approved for the treatment of the major depressive disorder. Dothiepin is not used in the United States. The central action of cis-dosulepin was compared with that of its antidepressant stereoisomer trans-dosulepin, cis-dosulepin exerted weaker anti-reserpine, anti-tetrabenazine, and 3H-5-HT (serotonin) uptake inhibiting actions than trans-dosulepin, but cis-dosulepin's inhibition of 3H-dopamine and 3H-norepinephrine uptake was slightly more potent than that of trans-dosulepin. On the other hand, cis-dosulepin exhibited extremely potent anticholinergic action in oxotremorine induced tremor, isolated ileum and the 3H-quinuclidinyl benzilate binding test. It also showed potent apomorphine enhancing the action and shortened the period of immobility in the forced swimming test in animals.

Fenspiride is an oxazolidinone spiro compound used as a drug in the treatment of certain respiratory diseases. It is approved for use in Russia for the treatment of acute and chronic inflammatory diseases of ENT organs and the respiratory tract (like rhinopharyngitis, laryngitis, tracheobronchitis, otitis and sinusitis), as well as for maintenance treatment of asthma. Fenspiride is marketed under the brand names Eurespal, Pneumorel, SYRESP, Oxofen and others. Erespal (fenspiride) is a drug with a bronchodilator and spasmolytic effect, which is often used in the complex therapy of bronchial asthma. Fenspiride has a clinically proven ability to increase the activity of the cilia of the bronchial ciliated epithelium, normalize the secretion of the bronchi and reduce its viscosity. Effectively removes bronchial obstruction, restores pulmonary gas exchange. Inhibits the metabolism of arachidonic acid, in parallel blocking histamine H1-receptors, since it is histamine that stimulates the chemical reactions of the transformation of arachidonic acid into the final metabolites-factors of inflammation. Reduces the production of other mediators of inflammation - serotonin and bradykinin. It blocks α-adrenergic receptors, the activation of which increases the secretion of bronchial glands. The complex effect of fenspiride reduces the pathological effect of a number of factors that promote hypersecretion of anti-inflammatory substances and cause obstruction of the bronchial tree. Has a pronounced antispasmodic and myotropic effect.

(E)-Isoeugenol is crystalline while compound with spice clove type odor. The melting point of E-isoeugenol is 33°C. E-Isoeugenol has been shown to cause contact and allergic dermatitis in humans. Positive skin patch tests in numerous individuals have confirmed the sensitizing ability of isoeugenol.

Quaternium-15, a preservative, is one of the most used substances and is added to several cosmetics and other industrial products. Quaternium-15 is a mixture of isomers, where the cis-form is the dominant form and where the trans-form is the minor component present as an impurity. Quaternium-15 can be found under a variety of names, most commonly those of the Dow Chemical Company: Dowicil 200 (cis isomer only), Dowicil 75 and Dowicil 100 (both a mix of cis and trans isomers). The isolated cis-compound is used primarily in cosmetic applications, with a maximum permitted concentration in the EU of 0.2%. DOWICIL 200 preservative (cis form) is used primarily as a preservative in a wide variety of personal-care and cosmetic products. It is designed to provide highly effective broad-spectrum antimicrobial activity, especially in water-based formulations. It is used in both leave-on and rinse-off application such as baby-care products, hair-care products, lotions, powders, and creams. The mixed product (cis- and trans-) is used in a wider range of formulations such as: emulsifiable metal-cutting fluids; latex and emulsion paints; liquid floor polishes and floor waxes; glues and adhesives. Recently, the cis-form has been classified as a CMR substance with the classification toxic to reproduction, category 3. This classification only concerns the cis-isomer:

alpha-Amyl cinnamaldehyde is a pale yellow liquid fragrance material with a floral smell used in allergenic testing.

Diazolidinylurea is a broad-spectrum antimicrobial preservative used in cosmetics and pharmaceutical preparations. It is especially active against gram-negative bacteria and is often combined with parabens. Diazolidinylurea is the most active member of the imidazolidinyl urea group, that acts as a formaldehyde releasers. Diazolidinylurea is used in many cosmetics, skin care products, shampoos, and conditioners, as well as a wide range of products including bubble baths, baby wipes, and household detergents.
