How To Choose The Right Antibiotic Medication Pt. 2 – Penicillin

Buying  antibiotics online can be difficult, especially choosing the right antibiotic to help heal from a nasty bacterial infection. Without proper information on the different types of antibiotics available, you might not get the right medication! Here at TheAntibioticsBlog, we can help you choose the right antibiotic because we inform you about how it works,  how it differs and the pros and cons of taking it. We believe the more information you have about antibiotics, the better equipped you are to handle bacterial infections – and that’s what matters to us!

Today, let us introduce you to Penicillin: The original antibiotic.

Scottish scientist Alexander Fleming discovered penicillin in 1928 and later won a Nobel laureate for his contribution to medicine. Penicillin and its many derivatives, Ampicillin, Carbenicillin, Dicloxacillin, Oxacillin, and Amoxicillin, are considered part of the first class. All penicillin antibiotics are part of the Beta-lactam class of antibiotics. The first generation all derived from Penicillium fungi and were extremely important for it’s time – as they were very effective against many serious and deadly diseases; Some of these diseases were responsible for millions of deaths that had plagued man through out the ages, like syphilis and staphylococcus infections. Penicillin are still widely used today, although many types of bacteria have developed resistance to earlier versions of the antibiotic.

Penicillin is effective against many gram-positive bacteria, including: gas gangrene, meningococcal meningitis, pneumococcal pneumonia, and some staphylococcal and streptococcal infections. The majority of gram-negative bacteria are resistant to the antibiotics, but a few bacteria are susceptible. Some bacteria are extremely responsive to high penicillin concentrations, or to certain classes of penicillin, and can be either killed or prevented from growing.

Penicillin can work in two ways: One, by interfering with the formation of the bacteria’s cell wall during its growth and development; it weakens the cell wall, which kills the bacteria – this is called it’s bactericidal effect. Two, Penicillin interferes with bacterial formation, preventing bacteria from duplicating and growing – this is called it’s bacteriostatic effect.

Penicillin is still used to treat many different types of infections caused by bacteria, like ear infections, throat infections, skin infections, dental infections, respiratory tract infections, urinary tract infections, gonorrhea, and other less serious bacterial infections.

The Pros and Cons
Penicillins are typically very safe, however they also pose a great risk to people with serious allergic reactions – most of the time these reactions can be extremely dangerous and severe, if not fatal. Penicillins are the most common medication allergy, people who are allergic to penicillin are, in addition, likely to have an allergic reaction to cephalosporins, another type of beta-lactam antibiotic. So it best to be tested by a doctor to make sure you have no allergies to it or other related antibiotics.

Another negative point about penicillin is that many pathogenic, Gram-positive bacteria produce enzymes called Penicillinases, these enzymes can negate the effects of penicillin; This is an example of bacteria developing an antibiotic resistance. Penicillins can sometimes be combined with beta-lactamase inhibitors that protect the penicillin from these bacterial enzymes and allow them to function properly; but keep in mind not all Penicillin does this.

One benefit to Penicillin is it can easily be broken down in the stomach by gastric acids, and it can be easily absorbed into the blood stream. However, this does not make Penicillin easy on the stomach- because it isn’t. In fact, most people will complain of stomach pain when taking penicillin.

Another benefit is price; due to Penicillin’s age and numerous different synthesis versions, a wide range of penicillin type antibiotics are on the market, which drives down their price. In addition, Penicillin has been on the market for a very long time, so the generic availability makes it very affordable.

Penicillin is available online without a prescription at your local online pharmacy!
