Penicillins constitute a collection of antibiotic medications. While natural penicillins are sourced from the mold Penicillium, there are also synthetic formulations available. These drugs are employed in treating various infectious conditions such as tonsillitis, bronchitis, bacterial endocarditis, syphilis, and pneumonia. Additionally, they are prescribed to forestall the recurrence of rheumatic fever. The mechanism of action involves the destruction of bacteria by inhibiting their ability to construct typical cell walls.
Diarrhea is a prevalent undesirable outcome linked to penicillin drugs. Additionally, penicillins have the potential to induce allergic responses in susceptible individuals. Allergic symptoms manifest promptly following drug ingestion and encompass urticaria (nettle rash), wheezing, and angioedema (swelling of body tissues, often around the mouth and eyes). In uncommon instances, penicillins can instigate the perilous allergic reaction known as anaphylactic shock. If an adverse reaction to a penicillin drug occurs, it is crucial to promptly cease the medication and seek urgent medical guidance.
