Indications of Coprin (10 mg+30 mg+1.25 mg)/5 ml
This preparation temporarily relieves these symptoms due to common cold, hay fever (allergic rhinitis) or other upper respiratory allergies:
Non-productive cough due to minor throat or bronchial irritation
Itching of the nose or throat
Itchy & watery eyes
Each 5 ml syrup contains-
Dextromethorphan Hydrobromide BP 20 mg
Phenylephrine Hydrochloride BP 10 mg
Triprolidine Hydrochloride BP 2.5 mg
Combined cough suppressants
Dextromethorphan, a centrally-acting antitussive agent, depresses the medullary cough center through sigma receptor stimulation, resulting to decreased sensitivity of cough receptors and interruption of cough impulse transmission.Pseudoephedrine is both an α-and β-adrenergic receptor agonist. It causes vasoconstriction via direct stimulation of α-adrenergic receptors of the respiratory mucosa. It also directly stimulates β-adrenergic receptors causing bronchial relaxation, increased heart rate and contractility.Triprolidine binds to the histamine H1 receptor. This block the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.

Combined cough suppressants
Mode Of Action
This preparation is a mixture of antitussive, decongestant and antihistamine agent. Dextromethorphan is a safe, effective, non-narcotic antitussive agent which has a central action on the cough centre in the medulla. Although structurally related to Morphine, it has no analgesic and habit forming properties and in general it has little sedative activity. Phenylephrine is a decongestant that shrinks blood vessels in the nasal passage. Phenylephrine is used for the temporary relief of stuffy nose, sinus, and ear symptoms caused by the common cold, flu, allergies, sinusitis & bronchitis. This medication works by decreasing swelling in the nose and ears, thereby lessening discomfort and making it easier to breathe. Triprolidine is an antihistamine used to relieve symptoms of allergy, hay fever, and the common cold. These symptoms include rash, watery eyes, itchy eyes/nose/throat/skin, cough, runny nose, and sneezing. It is a potent competitive histamine H1-receptor antagonist of the pyrrolidine class with mild central nervous system depressant properties which may cause drowsiness. By antagonizing another natural substance acetylcholine, it helps dry up some body fluids to relieve symptoms such as watery eyes and runny nose.
There are no specific data on use of this combination during pregnancy & lactation.
