What is the Difference Between Penicillin and Ampicillin?

Penicillin and ampicillin are antibiotics used to treat certain types of infections. Both drugs belong to the penicillin family and are considered effective in treating a wide range of bacterial infections. However, there are some differences between the two that should be taken into account when deciding which medication to take.

Uses and Treatment

Penicillin is used to treat a variety of bacterial infections, including strep throat, bronchitis, pneumonia, gonorrhea, and skin infections. It is also effective against some forms of meningitis. Ampicillin is used to treat more serious bacterial infections, such as urinary tract infections, meningitis, endocarditis, and other severe infections caused by susceptible bacteria.

Antibacterial Properties

Penicillin is a narrow-spectrum antibiotic that is effective against some types of bacteria. It is typically used to treat infections caused by Gram-positive bacteria, such as streptococci and staphylococci. Ampicillin is a broad-spectrum antibiotic that is effective against a wider range of bacteria, including Gram-negative bacteria, such as Haemophilus influenzae and Neisseria species.

Dosage and Administration

Penicillin is usually administered in tablet or liquid form. The dosage depends on the type of infection being treated, but it is typically taken two or three times a day for seven to fourteen days. Ampicillin is usually administered in capsule or liquid form. The dosage also depends on the type of infection being treated, but it is typically taken four times a day for ten to fourteen days.

Side Effects

The side effects of both medications may include nausea, vomiting, diarrhea, and rash. Other possible side effects include headache, dizziness, and confusion. People who are allergic to penicillin should not take ampicillin because they may experience an allergic reaction. In conclusion, penicillin and ampicillin are both antibiotics used to treat bacterial infections. The main differences between the two are their antibacterial properties, dosage and administration, and side effects. Both medications should only be taken under the supervision of a doctor who will determine the appropriate treatment for the specific type of infection.
