Study Notes
Key Facts about Antibiotics and Drug Interactions
- Antibiotics can be categorized into different classes, such as penicillins, cephalosporins, monobactams, carbapenems, tetracyclines, macrolides, and lincosamides.
- Penicillins, cephalosporins, monobactams, and carbapenems are all beta-lactam antibiotics that share a similar molecular structure.
- Tetracyclines are bacteriostatic antibiotics that inhibit protein synthesis by targeting the 30s ribosomal subunit.
- Tetracyclines have the broadest antimicrobial spectrum among all antibiotics.
- Macrolides are bacteriostatic antibiotics that inhibit protein synthesis by targeting the 50s ribosomal subunit.
- Lincosamides are also bacteriostatic antibiotics that inhibit protein synthesis by targeting the 50s ribosomal subunit.
- Antibiotic prophylaxis is required before dental treatment for patients with cardiovascular conditions such as prosthetic heart valve, history of endocarditis, heart transplant with valve pathology, or congenital heart problems.
- Patients with compromised immune systems, such as organ transplant recipients, individuals taking immunosuppressive drugs, or those undergoing cancer therapy, may also require antibiotic prophylaxis before dental treatment.
- The choice of antibiotic for prophylaxis depends on the specific condition and can include amoxicillin, clindamycin, or ampicillin.
- Some antibiotics can cause side effects, such as gastrointestinal upset (clindamycin), superinfections (broad-spectrum antibiotics), aplastic anemia (chloramphenicol), liver damage (tetracycline), or allergic cholestatic hepatitis (erythromycin).
- Drug interactions can occur between antibiotics and other medications. For example, bactericidal and bacteriostatic drugs should not be taken together as they can cancel each other out. Other interactions include reduced effectiveness of tetracycline with antacids or dairy products, enhanced action of anticoagulants with broad-spectrum antibiotics, decreased effectiveness of oral contraceptives with antibiotics, and inhibition of drug metabolism by macrolides.
- Antivirals like acyclovir and valacyclovir are used to treat herpes infections, while antifungals like fluconazole and ketoconazole are used to treat fungal infections, such as candidiasis.
