🧪 Sexually Transmitted Infections in Adults Objective 1 | Acyclovir/Valacyclovir, Doxy & Pen G 💊⚗️

🎯 Learning Objective 1: Describe the pharmacokinetic and pharmacodynamic properties of anti-infective agents used for the treatment of genital herpes, gonorrhea, chlamydia, and syphilis. Make pharmacology your superpower 🧠. We’ll translate PK-PD into dosing decisions for the major STI drugs: acyclovir-valacyclovir (HSV; intracellular activation, renal elimination, AUC targets), ceftriaxone (gonorrhea; time above MIC), doxycycline or azithromycin (chlamydia; intracellular penetration, AUC:MIC vs time-dependence), and benzathine penicillin G (syphilis; depot kinetics, time-dependent kill). We’ll connect tissue penetration (genital tract, pharynx, rectum), half-lives, and post-antibiotic effects to real-world regimens. 👍 If this clarified the “why” behind the doses, Like 👍, Subscribe 🔔, Comment 💬 your top PK/PD pearl, and Share 🔗 with classmates!
