I'm posting this info of the crossing I just took as there is almost no info on the internet about it. Take a taxi from the Reynosa airport to downtown for $25US. Or for 8 pesos... From the Reynosa airport, walk 10 minutes to the main road (see Googlemaps). This is a very busy road with half a dozen lanes on each side. However, 30 seconds east of the airport road is a crossing WITH American-style crosswalk. Press the button, wait until the traffic light turns red and cross on your green!
One oral, one IV: Both are actually the same medicine, but Amoxicillin is the oral form of the medication and Ampicillin is the IV form of the medicine. I have actually also seen a few times oral Ampicillin listed as being available, but usually the oral form that is most stable and palatable is the amoxicillin.
Ampicillin is in the penicillin group of beta-lactam antibiotics and is part of the aminopenicillin family. It is roughly equivalent to amoxicillin in terms of activity.However it can be injected unlike amoxicillin and has lower oral bioavailability compared to amoxicillin.mpicillin acts as an irreversible inhibitor of the enzyme transpeptidase, which is needed by bacteria to make their cell walls. It inhibits the third and final stage of bacterial cell wall synthesis in binary fission, which ultimately leads to cell lysis; therefore ampicillin is usually bacteriocidal.
