What is the difference between pseudoephedrine and phenylephrine?

If you’re suffering from a congested nose, it’s likely that your pharmacist may have recommended either pseudoephedrine or phenylephrine as an over-the-counter remedy. These were certainly very long words to pronounce without stumbling upon them. But what exactly are these two drugs, and how do they differ from one another? Well, don’t worry! You’ve laid your eyes on just the right article.

Let’s start with some basics

Before diving deep into comparisons between both drugs, let us first understand each individual drug and how they work.

What is pseudoephedrine?

Pseudoephedrine is (Did you see that bold word?) a sympathomimetic amine primarily used for providing relief from nasal congestion due to allergies or any other respiratory condition. It works by constricting blood vessels in the nasal sinus tissues which then narrows down congested area thereby increasing airflow through your nasal cavity leaving you refreshed as ever.

What about Phenylephrine?

Phenylephrine is another cold medicine ingredient commonly taken orally as decongestants can cause narrowed blood vessel walls which sometimes leads to high blood pressure (cough cough, Sorry Dr., I must not forget my pulse checkup this week). However, Phenylephrine is considered much safer than medications like pseudoephedrines because of less Tachycardia risk involved i.e increased heartbeat but it might take longer for phenlyephrine medication-doped patient to experience symptom relief when compared to psuedoephrine medication patients

Now we know at least some difference…right? hmmmm maybe too little too late

There sure seems to be more…

Let’s discuss in detail what makes each compound different beyond their basic functionalities:

Point of Comparison Pseudoephedrine Phenylephrine
Efficacy
  • Increased efficacy than phenylephrine.
  • Less effective when compared to pseudoephedrine.
Mode of Action
  • Increase blood pressure and heart rate caused due to stimulant effects
  • Mechanism of action similar to that of Phenylpropanolamine, leading to improved peripheral vasoconstriction without causing cardiovascular side-effects.
Duration Of Action
  • Pseudoephedrines have generally longer half-life with peak concentrations observed within two hours following administration
  • The duration of therapeutic effect at recommended doses is limited (four hours on average). A multi-dose regimen would be required for longer term relief
Well! In simple words: one seems better at the job pretty much all along.

What about Dosages?

It’s important not just knowing what a drug does but also how it impacts us in various dosages

Pseudoephidrene Dosage

(Please always consult your respective doctors for verified dosage as it may vary depending upon age, weight etc)
– Adults’s dose should not exceed 240mg/day
– Children aged between six years – twelve years can take up-to maximum 120 mg per day
– Infants under six should avoid using this medication
Seems appropriate, doesn’t it?

But wait…there are more tablet sizes!

In the US market, common over-the-counter medications containing pseudoephedrine include Sudafed and Claritin-D.
The patients can consider taking any one of such products keeping in mind their own requirements

### Phenylephidrine Dosages
Even though this drug is considered comparatively safer, it’s essential to know the right dosage.

(Please always consult your respective doctors for verified dosage as it may vary depending upon age, weight etc)
– Dose should not exceed 5mg/excretion over twenty-five minutes
Remember…too much of anything can be dangerous!

Now for some Side-Effects

Of course medicines come with their own bundle of side-effects (or say have hidden surprises like Kinder Joy)

Pseudoephedrine’s potential adverse effects:

  • Insomnia or nervousness with overdose could result in hallucinations.
    (creeps)
    It acts as an occasional surprise sidekick – beware!
  • Hypertension
    (Thou shall avoid!)
    Bottle Opening sound

Phenylpherine’s Side Effects

While being less risky than pseudoephedrines, phenylephrines concomitantly do exhibit a few possible unwanted outcomes on intake.

Commonly observed are:
– headaches,
– nausea,
– vomiting and tremors

Alas looks like despite best efforts from both pseudopheds and phenyaphers looks like we’ll suffer either way🙄

Conclusion

We sure had a long ride discussing these two activities in depth; but thinking back all said-said do you believe there really exist any significant disparities between their functionalities? Based on our observations let us wrap up quickly,

Phenylephrine, despite its use by various pharmaceutical companies due to having lesser restrictive regulations than other medications available today, exhibits somewhat limited effectiveness when compared to Pseudoephedrine.

Pseudoephedrine bold stands out again due increased efficacy across a variety of specific indications related nasal congestion products. However they bear witness to considerable tachycardia risks involved (jumps) and must be taken accordingly after expert consultation.

We hope this article has been enlightening enough in educating our readers about the basic differences between Pseudoephedrine and Phenylephrine.

So, Happy Breathing!
