What is the preferred treatment regimen for syphilis using Bicillin LA?

The preferred treatment regimen for syphilis using Bicillin LA is to administer 2.4 million units intramuscularly (IM) as a single injection. This dosing is particularly effective for treating early stages of syphilis and is supported by guidelines from health organizations. Bicillin LA, which contains benzathine penicillin G, is known for its long-acting properties, making a single dose sufficient for effective treatment in cases of primary and secondary syphilis.

The rationale for using this specific dosage is based on its ability to achieve therapeutic levels in the bloodstream, thereby effectively eliminating the Treponema pallidum bacteria responsible for syphilis. Furthermore, this approach minimizes the inconvenience of multiple doses, ensuring better patient compliance and successful outcomes in managing the disease. Other dosing routes or amounts mentioned in the options do not align with the established treatment protocols for syphilis and are therefore not preferred.
