Penicillins

Penicillins are a group of antibiotics derived from Penicillium fungi. They are commonly used to treat a variety of bacterial infections by inhibiting the growth of bacteria. Penicillins work by interfering with the bacterial cell wall synthesis, leading to the weakening and eventual death of the bacteria.

Types of Penicillins

There are several types of penicillins, including:

• Penicillin G: This is the original penicillin discovered by Alexander Fleming and is effective against a wide range of bacteria.
• Amoxicillin: A commonly prescribed penicillin used to treat a variety of infections such as ear, nose, and throat infections.
• Ampicillin: Effective against both gram-positive and gram-negative bacteria, often used for urinary tract infections.
• Penicillin V: Similar to penicillin G but more resistant to acid, often used for oral administration.
