Helsinki Pharma Pvt. Ltd. is a prominent pharmaceutical company known for its range of healthcare products. One of their popular formulations is a combination medication consisting of Levocetirizine 5 mg and Phenylephrine 10 mg. This formulation is commonly used to treat symptoms related to allergies and the common cold. Levocetirizine is an antihistamine that works by blocking the action of histamine, a substance in the body that leads to allergy symptoms such as sneezing, itching, watery eyes, and runny nose. By inhibiting the effects of histamine, Levocetirizine helps in relieving these symptoms and provides relief to individuals suffering from allergies. Phenylephrine, on the other hand, is a decongestant that works by narrowing the blood vessels in the nasal passages. This action leads to a decrease in swelling and congestion in the nasal passages, making it easier to breathe. Phenylephrine is commonly used to alleviate nasal congestion caused by conditions such as the common cold, sinusitis, or allergies. When combined, Levocetirizine and Phenylephrine work synergistically to provide relief from both the allergic symptoms and nasal congestion.
