Diphenhydramine Ammonium Chloride Sodium Citrate Menthol syrup- Coughing at night. A blocked chest. A throat that just won’t stop irritating. These are problems that millions of people face every day. And most of the time, they need more than one kind of relief.

This syrup combines four active ingredients in one formula. Ammonium chloride helps thin the thick mucus sitting in your chest. That makes it easier to cough it up. Diphenhydramine works on allergic cough, the kind triggered by dust, pollen, or seasonal changes. Menthol and sodium citrate together soothe the throat and reduce that scratchy, burning feeling. So in one bottle, you get mucus relief, allergy control, and throat comfort, all at once.

Pax Healthcare manufactures this syrup under the brand name P-Rex from its WHO-GMP and DCGI-approved facility in Chandigarh. PCD pharma partners get full monopoly rights for their area. That means less competition and better business from day one.

How Dry and Wet Cough Relief Syrup Works

Each ingredient in this syrup has a specific job to do. Ammonium chloride increases fluid in the airways. This makes thick mucus thinner and easier to cough out. Sodium citrate works the same way; it loosens mucus and helps clear the chest faster.

Diphenhydramine is an antihistamine. It blocks the signals that trigger an allergic cough. So if dust or pollen is causing the cough, this ingredient helps stop it at the root.

Menthol gives that instant cool feeling. It calms the throat lining and reduces irritation. It also makes breathing feel a little easier.

Together, these four ingredients work on the cough from different angles, and that is what makes this combination effective.
