Registered pharmacist Dennis R. Mckinley, RPH holds a California State Board of Pharmacy license and serves La Mesa's Grossmont area from the 91942 medical-office corridor on Parkway Drive. Pediatric dosing protocols for patients referred by Grossmont Pediatrics require weight-based milligram-per-kilogram calculations that adjust liquid-suspension and chewable-tablet formulations across antibiotic and antiviral categories. The pharmacist's scope under California SB 493 includes furnishing naloxone (Narcan) without a physician's prescription, administering travel vaccines, and initiating hormonal contraceptives through a standardized protocol. Post-discharge medication reconciliation for patients transitioning from inpatient rehabilitation at Grossmont Post Acute Care involves cross-checking active drug lists against new discharge orders to flag therapeutic duplications and dosage conflicts. The practice specializes in narrow-therapeutic-index medications—warfarin, levothyroxine, digoxin, and phenytoin—where brand-to-generic substitution requires bioequivalence verification against FDA-approved AB-rated product classifications.
