Question: What Receptors Does Pseudoephedrine Work?

Pseudoephedrine acts on α- and β2-adrenergic receptors, to cause vasoconstriction and relaxation of smooth muscle in the bronchi, respectively. α-Adrenergic receptors are located on the muscles lining the walls of blood vessels.

What is the mechanism of action of pseudoephedrine?

Mechanism of Action Pseudoephedrine is a sympathomimetic with a mixed mechanism of action, direct and indirect. It indirectly stimulates alpha-adrenergic receptors, causing the release of en- dogenous norepinephrine (NE) from the granularity of neurons, while it directly stimulates beta-adrenergic receptors [11–13].

What does pseudoephedrine bind to?

Pseudoephedrine is a mixed-acting decongestant, which activates α- and β-adrenergic receptors directly by binding to the receptor itself, and indirectly by causing norepinephrine release in synaptic nerve terminals. Pseudoephedrine is also used illicitly in the production of methamphetamine.

How does pseudoephedrine work on the brain?

It causes vasoconstriction by stimulating primarily alpha-adrenergic receptors. It also has weak activity at beta-adrenergic receptors. It is chemically related to ephedrine, but with less central nervous system activity (fewer effects on the brain).

Which nervous system does pseudoephedrine stimulate?

Pseudoephedrine is a sympathomimetic (an agent that mimics stimulation of the sympathetic nervous system ) that acts predominantly on the alpha receptors but has little or no effect on beta receptors.

What receptors does phenylephrine work?

Phenylephrine is a man-made drug that stimulates receptors ( alpha1 receptors ) on blood vessels and cause blood vessels to constrict (vasoconstriction). It is a vasoconstrictor medication, structurally similar to epinephrine and ephedrine. Vasoconstriction increases blood pressure.

What is the function of pseudoephedrine?

Pseudoephedrine is used to relieve nasal congestion caused by colds, allergies, and hay fever. It is also used to temporarily relieve sinus congestion and pressure. Pseudoephedrine will relieve symptoms but will not treat the cause of the symptoms or speed recovery.

Does pseudoephedrine increase dopamine?

The suggested mechanism by which pseudoephedrine may improve performance is the reduction of an individuals perceived exertion, occuring in response to an increase in dopamine (Hodges et al. 2006).

Why does pseudoephedrine make me feel good?

Pseudoephedrine can cause a sense of euphoria. It causes a pleasant feeling in the body of the user. Many of the individuals who use this substance frequently do so because of these pleasurable effects. So, it can be hard for individuals to stop using the substance.

Is pseudoephedrine a CNS stimulant?

Both caffeine (CAF) and pseudoephedrine (PSE) are proposed to be central nervous system stimulants. However, during competition, CAF is a permitted substance, whereas PSE is a banned substance at urinary levels >150 μg · ml(-1).

How does pseudoephedrine enhance performance?

Previously reviewed by Trinh et al. [3], these effects include increased systolic and diastolic blood pressure and heart rate, vasoconstriction in the cutaneous vessels, vasodilation in the skeletal muscle, and breakdown of glycogen in the liver and muscle.

Does pseudoephedrine increase serotonin levels?

The risk or severity of serotonin syndrome can be increased when Pseudoephedrine is combined with Dexmethylphenidate. The risk or severity of serotonin syndrome can be increased when Pseudoephedrine is combined with Dextroamphetamine.

Does pseudoephedrine help with focus?

It may improve thinking by improving breathing and sleep. Sinus problems are associated with sleep disorders, particularly obstructive sleep apnea. When using pseudoephedrine you may be sleeping more soundly at night and that is directly associated with improved thinking and memory.

Why do decongestants cause vasoconstriction?

Nasal decongestants are vasoconstrictors that belong to the pharmacologic class sympathomimetic amines. They exert their primary action by activating alpha-adrenergic receptors on blood vessels of the nasal mucosa. This results in vasoconstriction, which decreases blood flow through the nasal mucosa and shrinks tissue.

What is the mechanism of decongestant?

The mechanism by which decongestants produce their action is activation of postjunctional alpha-adrenergic receptors found on precapillary and postcapillary blood vessels of the nasal mucosa.

How does Sudafed affect neurotransmitters?

Pseudoephedrine displaces norepinephrine from storage vesicles in presynaptic neurones, thereby releasing norepinephrine into the neuronal synapses where it stimulates primarily alpha-adrenergic receptors.
