Propantheline is an antimuscarinic agent used for the treatment of excessive sweating (hyperhidrosis), cramps or spasms of the stomach, intestines (gut) or bladder, and involuntary urination (enuresis). It can also be used to control the symptoms of irritable bowel syndrome and similar conditions. Propantheline is one of a group of antispasmodic medications which work by blocking the action of the chemical messenger acetylcholine, which is produced by nerve cells, to muscarinic receptors present in various smooth muscular tissues, in places such as the gut, bladder, and eye. Normally, the binding of acetylcholine induces involuntary smooth muscular contractions. Varying degrees of drying of salivary secretions may occur as well as decreased sweating. Ophthalmic side effects include blurred vision, mydriasis, cycloplegia, and increased ocular tension. Other reported adverse reactions include urinary hesitancy and retention, tachycardia, palpitations, loss of the sense of taste, headache, nervousness, mental confusion, drowsiness, weakness, dizziness, insomnia, nausea, vomiting, constipation, bloated feeling, impotence, suppression of lactation, and allergic reactions or drug idiosyncrasies including anaphylaxis, urticaria and other dermal manifestations.

Methoxyphenamine also known as 2-methoxy-N-methylamphetamine (OMMA), is a beta adrenergic receptor agonist nd is used as a bronchodilator to treat asthma, chronic obstructive pulmonary disease (COPD) and postinfectious cough. In addition, methoxyphenamine using is prohibited in sports according to the regulations of the World Anti-Doping Agency (WADA).

Sodium gualenate (Azunol ST Tablets) is a water-soluble derivative of azulene, a natural product which is an antiinflammatory component of chamomile of the family of Asteraceae. Sodium gualenate was originally studied as an antiulcer agent, is primary indicated in conditions like Duodenal ulcer, Gastric ulcer, Gastritis, but it is also clinically used as a therapeutic agent in the treatment of inflammation of the mouth and throat, for example, pharyngitis as well as other inflammatory diseases such as tonsillitis, stomatitis and conjunctivitis. Although the mechanism by which sodium azulene sulfonate inhibited the capsaicin-induced pharyngitis is not yet unraveled, antioxidative effect, but not inhibitory effect on cyclooxygenase pathway, might be involved.

Menthyl 2-hydroxypropyl carbonate is a methyl ester used as a flavoring and cooling agent. It provides a prolonged physiological cooling sensation to the skin or mucus membrane. It is used in gum or confections.

Diisopropylamine (DIPA) is a secondary amine, which is used as a chemical intermediate, and catalyst for the synthesis of pesticides and pharmaceuticals. DIPA is primarily used as a precursor for the herbicides dilate and triallate, as well as certain sulfenamides used in the vulcanization of rubber. It is used for adjusting pH in cosmetic formulations, in colognes, and toilet cleaners. It is associated with tobacco either as a natural component of tobacco, pyrolysis product (in tobacco smoke), or additive for one or more types of tobacco products. When given intravenously to hypertensive patients, DIPA is known as an antihypertensive agent. DIPA exerts its action by lowering arterial blood pressure, reduction of stroke volume and cardiac output. DIPA reduced blood glucose concentrations in fasted mice and in fasted, glucose-loaded, or streptozotocin-diabetic rats. DADA (diisopropylamine dichloroacetate) was identified as an active domain of pangamic acid. DADA is a vasodilator of peripheral and cerebral arterioles. DADA also considered to aid in the detoxification of chemical and metallic metabolites, possibly by the formation of chelate-like compounds whose excretion by the kidneys is facilitated and increased. DADA increases oxygen utilization and cortical glucose uptake.

Egualen is an azulene derivative developed for the treatment of peptic ulcer and marketed in Japan under the tradename Azuloxa. The drug exerts its antiulcer activity by antagonizing TXA2 production.

Tezosentan (Veletri; Ro 61–0612) is a dual endothelin receptor antagonist that has been shown to improve cardiac output, decrease pulmonary capillary wedge pressure, and reduce pulmonary and systemic vascular resistance in initial clinical studies in acutely decompensated heart failure. Tezosentan is a water-soluble ET-1 receptor antagonist with high affinity to both ETA and ETB receptors but greater potency for the ETA receptor subtype. Clinical studies demonstrated mixed results for Tezosentan regarding its efficacy and tolerability in the management of decompensated heart failure. The side effects of Tezosentan include a headache, nausea, and hypotension.

Ipronidazole is an antiprotozoal drug of the nitroimidazole class used in veterinary medicine. Ipronidazole (2-isopropyl-1-methyl-5-nitroimidazole) is used for the treatment of histomoniasis in turkeys and in swine dysentery.

Isoaminile is a cough suppressant that acts by influencing the cough centre.
