Mechanism of Action

At the core of Cetryn’s prowess lies its active metabolite, Flurbiprofen. It operates as a highly selective antagonist of peripheral histamine H1-receptors, a feature that extends its utility across various domains, from the gastrointestinal tract to blood vessels and the respiratory tract.


Cetryn demonstrates its versatility by effectively addressing a spectrum of conditions, including chronic idiopathic urticaria, perennial allergic rhinitis, seasonal allergic rhinitis, allergic asthma, physical urticaria, and atopic dermatitis. Additionally, it plays a pivotal role in the management of seasonal allergic rhinitis, conjunctivitis, pruritus, and urticaria, and acts as a potent ally against allergen-induced asthma.


Cetryn, an antihistamine drug and a metabolite of hydroxyzine, primarily exerts its effects through the selective inhibition of peripheral H1 receptors. Extensive studies in both animal and human models have validated its clinical efficacy.

Notably, Cetryn demonstrates minimal anticholinergic and antiserotonergic effects, ensuring a more tolerable experience for patients. However, it’s essential to note that some individuals may experience dry mouth, albeit at a frequency higher than with a placebo. Importantly, in vitro receptor binding studies have confirmed Cetryn’s exclusive affinity for H1 receptors. Furthermore, it exhibits limited penetration into the brain, as demonstrated in rat studies, minimizing potential central nervous system effects.

The Right Dosage for Cetryn

Determining the appropriate Cetryn dosage hinges on the patient’s age:

  • Adults and children over 6 years: 1 tablet (10 mg) once daily or ½ tablet twice daily.
  • Children 2-6 years: ½ tablet once daily.

Side Effects

While Cetryn, also known as Cetirizine, is generally safe and efficacious, it can induce certain side effects. The most prevalent of these is drowsiness, affecting more than 1 in 10 individuals. Other commonly reported side effects encompass headaches, dry mouth, nausea, dizziness, diarrhea, and stomach discomfort. These side effects, while typically non-emergent, warrant discussion with a healthcare provider if they endure or exacerbate.

Timely Onset and Duration of Cetryn’s Action

Cetryn’s effectiveness becomes apparent within a remarkably short timeframe. It typically takes between 20 to 42 minutes for the medication to commence its action, alleviating skin wheal and flare. Furthermore, Cetryn maintains its therapeutic effect for a duration exceeding or equal to 24 hours, ensuring sustained relief.

Recommended Dosage

The potential for overdose exists with any medication, including Cetryn. Exceeding the recommended dosage can heighten the risk and severity of side effects, such as dizziness, drowsiness, blurred vision, and constipation. However, it’s crucial to highlight that experiencing severe side effects, such as cardiovascular complications, necessitates doses significantly surpassing the recommended maximum.

In cases of accidental overdose, the advised approach involves symptomatic or supportive treatment, considering concurrently ingested medications. If you suspect an overdose, seek immediate medical attention. Symptoms may manifest as restlessness, nervousness, followed by drowsiness.

In conclusion, Cetryn Syrup, powered by Flurbiprofen and Thiocolchicoside, emerges as a dependable ally in the battle against cold and allergy symptoms. Its mechanism of action, diverse applications, and well-established safety profile underscore its significance in modern pharmaceuticals. However, adhering to recommended dosages remains paramount to ensure a safe and effective therapeutic experience. In case of any concerns or uncertainties, consulting with a healthcare professional is the prudent course of action.

The truth is that when we’re sick, or worried about getting sick, the internet won’t help.

According to Wikipedia, cyberchondria is a mental disorder consisting in the desire to independently make a diagnosis based on the symptoms of diseases described on Internet sites.

Why you can't look for symptoms on the Internet

If diagnoses could be made simply from a textbook or an article on a website, we would all be doctors and treat ourselves. Nothing can replace the experience and knowledge of specially trained people. As in any field, in medicine there are unscrupulous specialists, differences of opinion, inaccurate diagnoses and incorrect test results.
