Chloroquine (CQ) then becomes protonated (to CQ 2+), as the digestive vacuole is known to be acidic (pH 4.7); chloroquine then cannot leave by diffusion. Chloroquine caps hemozoin molecules to prevent further biocrystallization of heme, thus leading to heme buildup. Chloroquine binds to heme (or FP) to form the FP-chloroquine complex; this ...
It has a weak blood schizonticidal activity and is not recommended for therapy of acute infection. However it is useful in prophylaxis when combined with atovaquone or chloroquine (in areas where there is no chloroquine resistance). 3 mg/kg is the advised dosage per day, (hence approximate adult dosage is 200 mg).

Generally, antibiotics (like azithromycin [150]) are not effective against viruses, only some bacteria. [152] Azithromycin is sometimes given to patients hospitalized with COVID-19, but only to treat bacterial co-infection. Overuse of azithromycin causes antibiotic resistance, and rare side effects include heart arrhythmias and hearing loss ...
Chloroquine and hydroxychloroquine are anti-malarial medications also used against some auto-immune diseases. [51] Chloroquine, along with hydroxychloroquine, was an early experimental treatment for COVID-19. [52] Neither drug has been useful to prevent or treat SARS-CoV-2 infection.
In October 2021 a large network of companies selling hydroxychloroquine and ivermectin has been disclosed in the US, targeting primarily right-wing and vaccine hesitant groups through social media and conspiracy videos by anti-vaccine activists such as Simone Gold. The network had 72,000 customers who collectively paid $15 million for ...

The following is a list of antibiotics. The highest division between antibiotics is bactericidal and bacteriostatic . Bactericidals kill bacteria directly, whereas bacteriostatics prevent them from dividing.
Production of antibiotics is a naturally occurring event, that thanks to advances in science can now be replicated and improved upon in laboratory settings. Due to the discovery of penicillin by Alexander Fleming, and the efforts of Florey and Chain in 1938, large-scale, pharmaceutical production of antibiotics has been made possible.
