Clofedanol (INN) or chlophedianol (BAN), sold under the brand name Ninjacof among others, is a centrally acting cough suppressant used in the treatment of dry cough. Clofedanol has local anesthetic, antispasmodic, and antihistamine properties, [1] and may have anticholinergic effects at high doses. [2]
Adverse effects may include irritability, drowsiness, nightmares, vertigo, nausea or vomiting, visual disturbances or hallucinations, and urticaria. There are potential interactions with other anticholinergics, CNS depressants, and alcohol. [3]
Unlike many other antitussive drugs such as dextromethorphan, it binds poorly to the sigma-1 receptor. [4]
Chlophedianol was approved for OTC status in 1987 by the FDA OTC monograph process [5] and its safety and efficacy data are limited. It was formerly sold over-the-counter in the United States under the trade name Ulo, as a syrup with a dosage of 25 mg/5 mL. [6] It is now marketed under the brand name of Ninjacof in the U.S.
It is marketed in Canada under the trade name Ulone. GM Pharmaceuticals owns the patents to 113 combinations with Chlophedianol and was the first company to launch the cough suppressant in the United States. [7]
It is sold in Japan as an over-the-counter drug under the name Coldrin. [8] It has been marketed in Germany as Pectolitan and in Spain as Gentos. [9]
Dextromethorphan, or DXM, a common active ingredient found in many over-the-counter cough suppressant cold medicines, is used as a recreational drug and entheogen for its dissociative effects. Street names include Brownies, Dextro, Drix, Gel, Groove, Lean, Mega-perls, Poor man's ecstasy, Red devils, Robo, Rojo, Rome, Skittles, Sizzurp, Sky and Velvet.
Over-the-counter (OTC) drugs are medicines sold directly to a consumer without a requirement for a prescription from a healthcare professional, as opposed to prescription drugs, which may be supplied only to consumers possessing a valid prescription. In many countries, OTC drugs are selected by a regulatory agency to ensure that they contain ingredients that are safe and effective when used without a physician's care. OTC drugs are usually regulated according to their active pharmaceutical ingredient (API) and strengths of final products.
Cold medicines are a group of medications taken individually or in combination as a treatment for the symptoms of the common cold and similar conditions of the upper respiratory tract. The term encompasses a broad array of drugs, including analgesics, antihistamines and decongestants, among many others.

Guaifenesin, also known as glyceryl guaiacolate, is an expectorant medication taken by mouth and marketed as an aid to eliminate sputum from the respiratory tract. Chemically, it is an ether of guaiacol and glycerine. It may be used in combination with other medications. A 2014 study found that guaifenesin has no effect on sputum production or clearance in upper respiratory infections.

In 2022, the FDA approved the combination dextromethorphan/bupropion to serve as a rapid acting antidepressant in patients with major depressive disorder.
Pentoxyverine (rINN) or carbetapentane is an antitussive commonly used for cough associated with illnesses like common cold.
