Pseudoephedrine HCl powder is one of the four active components of the herb Ephedra. It is able to induce fat loss via increasing the amount of fat available for fuel as well as by increasing heat expenditure. It has been implicated in increasing the metabolic rate by up to 5% in humans.

Pseudoephedrine HCl powder is used for temporary relief of shortness of breath, chest tightness, and wheezing due to bronchial asthma. Ephedrine may also be used for other conditions as determined by your doctor.

Pseudoephedrine HCl powder is a decongestant and bronchodilator. It works by reducing swelling and constricting blood vessels in the nasal passages and widening the lung airways, allowing you to breathe more easily.

Side effects of Pseudoephedrine HCl powder

All medicines may cause side effects, but many people have no, or minor, side effects. Check with your doctor if any of these most common side effects persist longer than one hours or become worse:

Dizziness; headache; nausea; nervousness; tremor; loss of appetite; restlessness; sleeplessness; stomach irritation.
Seek medical attention right away if any of these severe side effects occur:

Severe allergic reactions (rash; hives; difficulty breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue); difficulty urinating.

Uses

Pseudoephedrine HCl is basically a synthetic version of ephedrine. Ephedra extract and ephedrine alkaloids (the latter of which is banned) are found naturally in plants, while ephedrine HCL is manufactured in a laboratory. Ephedrine HCL has a wide variety of medicinal uses. It’s often used as a bronchodilator to relieve symptoms of bronchial asthma which include shortness of breath, wheezing, coughing, and chest tightness. It has also been used to treat hypotension and nasal congestion with varying degrees of success.

How to take Pseudoephedrine Hcl

In an ECA stack, ephedrine is dosed at 20-24mg for three doses taken throughout the day.

Human studies have found success with ephedrine in isolation on fat metabolism with doses of 20-50mg thrice a day. The higher range (150mg) may be too stimulatory for some and can induce headaches or light hand tremors.

Ephedrine tends to be consumed with xanthine compounds like caffeine and sometimes with Aspirin. The combination of Ephedrine and caffeine is shown repeatedly to be highly synergistic.

Mechanism of action

Pseudoephedrine, a sympathomimetic amine, acts on part of the sympathetic nervous system (SNS). The principal mechanism of action relies on its indirect stimulation of the adrenergic receptor system by increasing the activity of norepinephrine at the postsynaptic α and β receptors. The presence of direct interactions with α receptors is unlikely, but still controversial.L-ephedrine, and particularly its stereoisomer norpseudoephedrine (which is also present in Catha edulis) has indirect sympathomimetic effects and due to its ability to cross the blood-brain barrier, it is a CNS stimulant similar to amphetamines, but less pronounced, as it releases noradrenaline and dopamine in the substantia nigra.

The presence of an N-methyl group decreases binding affinities at α receptors, compared with norephedrine. Ephedrine, though, binds better than N-methylephedrine, which has an additional methyl group at the nitrogen atom. Also, the steric orientation of the hydroxyl group is important for receptor binding and functional activity.

About Pseudoephedrine
Pseudoephedrine HCl powder

Pseudoephedrine is a diastereomer of ephedrine and is readily reduced into methamphetamine or oxidized into methcathinone.

Although pseudoephedrine occurs naturally as an alkaloid in certain plant species (for example, as a constituent of extracts from the Ephedra species, also known as ma huang, in which it occurs together with other isomers of ephedrine), the majority of pseudoephedrine produced for commercial use is derived from yeast fermentation of dextrose in the presence of benzaldehyde. In this process, specialized strains of yeast (typically a variety of Candida utilize or Saccharomyces cerevisiae) are added to large vats containing water, dextrose, and the enzyme pyruvate decarboxylase (such as found in beets and other plants). After the yeast has begun fermenting the dextrose, the benzaldehyde is added to the vats, and in this environment, the yeast converts the ingredients to the precursor l-phenylacetylcarbinol (L-PAC). L-PAC is then chemically converted to pseudoephedrine via reductive amination.

More about Pseudoephedrine

The bulk of pseudoephedrine is produced by commercial pharmaceutical manufacturers in India and China, where economic and industrial conditions favor its mass production for export.

It is a sympathomimetic amine. Its principal mechanism of action relies on its direct action on the adrenergic receptor system. The vasoconstriction that It produces is believed to be principally an α-adrenergic receptor response.

It 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. When these receptors are activated, the muscles contract, causing the blood vessels to constrict (vasoconstriction). The constricted blood vessels now allow less fluid to leave the blood vessels and enter the nose, throat and sinus linings, which results in decreased inflammation of nasal membranes, as well as decreased mucus production. Thus, by constriction of blood vessels, mainly those located in the nasal passages, pseudoephedrine causes a decrease in the symptoms of nasal congestion. Activation of β2-adrenergic receptors produces relaxation of the smooth muscle of the bronchi, causing bronchial dilation and in turn, decreasing congestion (although not fluid) and difficulty breathing.
