What are Penicillins?
Penicillins are a group of antibiotics that are derived from Penicillium fungi. They are effective in treating a wide range of bacterial infections by inhibiting the formation of the bacterial cell wall.Mechanism of Action
Penicillins work by inhibiting the synthesis of peptidoglycan, a key component of the bacterial cell wall. This weakens the cell wall, leading to the lysis and destruction of the bacteria.Types of Penicillins
There are several types of penicillins, including:- Natural penicillins: Penicillin G and penicillin V
- Semi-synthetic penicillins: Amoxicillin, ampicillin, and oxacillin
- Extended-spectrum penicillins: Piperacillin and ticarcillin
Uses
Penicillins are used to treat various bacterial infections, including:- Strep throat
- Pneumonia
- Skin infections
- Urinary tract infections
- Ear infections
- Sinus infections
Side Effects
Common side effects of penicillins include:- Allergic reactions
- Nausea and vomiting
- Diarrhea
- Yeast infections
