Chlorphenamine (also known as chlorpheniramine, CP, or CPM) is a first-generation antihistamine used in the prevention of the symptoms of allergic conditions such as rhinitis and urticaria. Its sedative effects are relatively weak compared to other first-generation antihistamines. Chlorphenamine is one of the most commonly used antihistamines in small-animal veterinary practice.
METHDILAZINE (1982-37-2)  
methdilazine hydrochloride
Methdilazine (Dilosyn, Tacaryl) is a first-generation antihistamine with anticholinergic properties of the phenothiazine class.
ketorolac (66635-83-4, 74103-06-3)  
Ketorolac, sold under the brand name Toradol among others, is a nonsteroidal anti-inflammatory drug (NSAID) in the family of heterocyclic acetic acid derivatives, used as an analgesic. It is considered a first-generation NSAID. Ketorolac acts by inhibiting the bodily synthesis of prostaglandins.
antazoline (91-75-8)  
Antistine  ·  Antazoline Phosphate  ·  Antazoline Hydrochloride
Antazoline is a 1st generation antihistamine with anticholinergic properties used to relieve nasal congestion and in eye drops, usually in combination with naphazoline, to relieve the symptoms of allergic conjunctivitis. To treat allergic conjunctivitis, antazoline can be combined in a solution with tetryzoline. The drug is a Histamine H1 receptor antagonist: selectively binding to but not activating the receptor, thereby blocking the actions of endogenous histamine and subsequently leading to the temporary relief of the negative symptoms brought on by histamine.
thiethylperazine (1420-55-9, 1179-69-7)  
Torecan  ·  Norzine  ·  Novartis Brand of Thiethlperazine Maleate
Thiethylperazine (Torecan) is an antiemetic of the phenothiazine class. Though it was never licensed or used as an antipsychotic, it may have such effects. Thiethylperazine activates the transport protein ABCC1 that clears beta-amyloid from brains of mice.
methapyrilene (91-80-5)  
Thionylan  ·  Lullamin  ·  Tenalin
tetrahydrozoline (84-22-0)  
Visine  ·  tetrahydrozoline hydrochloride  ·  Tyzine
Tetryzoline (INN; also known as tetrahydrozoline), a derivative of imidazoline, is found in over-the-counter eye drops and nasal sprays. Other derivatives include naphazoline, oxymetazoline, and xylometazoline. Tetrahydrozoline is an alpha agonist and its main mechanism of action is the constriction of conjunctival blood vessels.
Polaramine  ·  dexchlorpheniramine maleate  ·  Polaramin
Dexchlorpheniramine (trade name Polaramine) is an antihistamine with anticholinergic properties used to treat allergic conditions such as hay fever or urticaria. It is the pharmacologically active dextrorotatory isomer of chlorpheniramine.

Mepyramine  ·  Pyrilamine Maleate  ·  Anthisan
Mepyramine, also known as pyrilamine, is a first generation antihistamine, targeting the H1 receptor. However, it rapidly permeates the brain often causing drowsiness. It also has anticholinergic properties.
chlorcyclizine (82-93-9)  
chlorcycline  ·  chlorocyclizin  ·  Histachlorazine
Chlorcyclizine (Di-Paralene, Mantadil, Pruresidine, Trihistan) is a first-generation antihistamine of the diphenylmethylpiperazine group marketed in the United States and certain other countries. It is used primarily to treat allergy symptoms such as rhinitis, urticaria, and pruritus, and may also be used as an antiemetic. In addition to its antihistamine effects, chlorcyclizine also has some anticholinergic, antiserotonergic, and local anesthetic properties.
Roflumilast (162401-32-3)  
Roflumilast (trade names Daxas, Daliresp) is a drug that acts as a selective, long-acting inhibitor of the enzyme phosphodiesterase-4 (PDE-4).
