Penicillin G - First penicillin available for clinical use - Therapeutic Uses: bactericidal to gram positive and some gram negative - Best absorbed IM, worst is oral - Only potassium penicillin G can be given IV (concern for kidney/heart patients) - excreted by the kidney - minimal metabolism - risks in renal pts, acutely ill, elderly and infants - half life = 30 minutes - side effects = pain at site of IM injection, neurotoxicity (seizures), hyperkalemia (cardiac arrest), and necrosis of skin i...

Causes of drug resistance: - Answer-1.Recent use of antibiotics Overuse of broad-spectrum antibiotics 2.Age younger than 2 years or older than 65 years 3.Day-care center attendance 4.Exposure to young children 5.Multiple medical comorbidities 6.Immunosuppression Why is it important to vaccinate with pneumococcal vaccine? - Answer-Vaccination with pneumococcal vaccine has decreased resistance to antibiotics What class of antibiotics are the most effective? - Answer-Beta-lactam Beta lact...

Penicillin G *** - ANSWER - First PCN given PO and IM - PO only about 1/3 of dose is absorbed - IM and IV are most effective (to get therapeutic serum level) (IM is painful) - primarily bactericidal Penicillin V *** - ANSWER - next type produced - 2/3 absorbed by GI tract, less patent than PCN G - It is effective against mild - moderate infections, including anthrax PCNS (structure) - ANSWER - beta-lactam antibiotics. - beta-lactam structure interferes with bacterial cell wall synth...
