Pharmacology What is the difference between claritin and claritin-D?
What is the difference between claritin and claritin-D?
The difference is that "D" stands for "decongestant". Pseudoephedrine has been added to these products, which has a decongestant effect.
@ekaterina-gribacheva Adding pseudoephedrine to these products for additional congestion relief. Antihistamines themselves do not greatly affect nasal congestion. Pseudoephedrine acts on alpha-adrenergic receptors in the nose, narrowing blood vessels, thereby allowing less fluid in the nose to cause stagnation (the effect of "drying"). Pseudoephedrine added to antihistamines such as Claritin-D or Zyrtec-D may help alleviate the symptoms of allergic rhinitis, including congestion. However, the addition of pseudoephedrine is associated with an increased likelihood of side effects such as high blood pressure, insomnia and headache. For these reasons, drugs with pseudoephedrine in them are usually not recommended for people with high blood pressure, glaucoma, vascular diseases, hyperthyroidism, bladder neck obstruction or those taking monoamine oxidase inhibitors.
Interesting. I thought we were talking about a protein, clathrin, which is involved in endocytosis)
@argentum I think if we were talking about protein, the topic would fall into microbiology, not pharmacology)
