Sudogest – An Overview

Sudogest - An Overview

Sudogest is an over-the-counter that is used to treat stuffy noses. The medicine contains pseudoephedrine. This particular medicine has been used to treat nasal congestions for ages.


Sudogest contains pseudoephedrine. That is a decongestant. It is found in many medical preparations in over-the-counter drugs. It is sometimes used alone and has an NSAID, antihistamines, and acetaminophen added to the preparation.

Mechanism of Action

Pseudoephedrine is termed a sympathomimetic. It acts on two receptors:

  • Alpha-adrenergic receptor
  • Beta-2 adrenergic receptor

It produces vasoconstriction on alpha-adrenergic receptors present in the smooth muscle of the bronchi. It causes relaxation of the smooth muscle of bronchi by binding to the beta-2 adrenergic receptor. These different types of reactions work effortlessly in relieving nasal decongestion.

Alpha-adrenergic Receptors

Alpha-adrenergic receptors are present on the lining of blood vessels, so when pseudoephedrine binds o this receptor, it causes vasoconstriction. This vasoconstriction causes the blood vessels to constrict. Due to this, less fluid leaves the vessels and reaches the sinuses. This will, in turn, decrease the inflammation of the nose and reduce mucus production.

Beta-2 Adrenergic Receptors

When the bronchi get congested, it gets filled with a thick mucus-like substance that makes it difficult to breathe. Pseudoephedrine binds to the beta-2 receptor of the bronchi and causes relaxation of smooth muscles. This will decrease the congestion of the bronchi and ease breathing.


Pseudoephedrine is readily absorbed in the gastrointestinal tract. The half-life is approximately 5-8 hours. It is excreted in the urine, and a small amount of pseudoephedrine is also through the liver.

Uses of pseudoephedrine

Even though it is a decongestant, it has many other uses as well. Following are the uses of pseudoephedrine:

Amphetamine Production

Pseudoephedrine is a precursor that is used in the manufacturing of methamphetamine and methcathinone. That is why the sale of pseudoephedrine is checked in pharmacies in different states. Due to these restrictions, pharmaceutical firms are now trying to find an alternative for pseudoephedrine.

Treatment of Congested Sinuses

Nasal congestion or congested sinuses happen when the blood vessels of the nose become swollen. There are many reasons this can happen. Cold, flu, and allergies are some of the causes of swollen sinuses.

Pseudoephedrine used in the Treatment of Allergies

Allergies or hay fever happens because of the inflammation of the sinuses, among other reasons. Allergies are exacerbated when pollen season is in full swing. Many people who suffer from allergies start taking pseudoephedrine before the season starts. It is important to note that pseudoephedrine will not treat the underlying cause of allergy but will reprieve from the other symptoms.

Although pseudoephedrine and montelukast have the same efficacy, people still prefer pseudoephedrine as it provides immediate relief from nasal decongestion. A study was done on 58 people to compare montelukast and pseudoephedrine efficacy. It was found that both were equally effective in treating seasonal allergic rhinitis.

Pseudoephedrine used in the Treatment of Cold

It works the same way for colds as it works for allergies. It does not treat the cause of the common cold, but it will relieve the nasal congestion caused by the common cold.

Who Can Take Pseudoephedrine?

Pseudoephedrine can be taken by all adults and children that are over 12 years of age. Sometimes, pseudoephedrine is given to children who are six years old. Still, it depends on the symptoms and the evaluation of your pharmacist. Do not self-medicate.
