History of Bicillin for Syphilis

[1] Bicillin (also known as aqueous procaine penicillin G and benzathine penicillin G) has been used to treat syphilis for over 70 years. It was first introduced in the 1940s as a long-acting form of penicillin for the treatment of syphilis. DrugPatentWatch.com

How Bicillin Works

Bicillin is an injectable medication that contains two types of penicillin: procaine penicillin G and benzathine penicillin G. Procaine acts quickly to rapidly reduce the infection, while benzathine penicillin G provides a longer-lasting action, helping to ensure that the infection is fully eliminated. DrugPatentWatch.com

Treatment Regimens for Syphilis

In the United States, the Centers for Disease Control and Prevention (CDC) recommend Bicillin CR as the treatment for syphilis in its early stage. People with latent syphilis can receive either 2.4 million units of Benzathine Penicillin G or Procaine Penicillin G with 666,000 units of procaine penicillin G intravenously daily for 10 days.

However, in people with HIV infections and neurological complications (including meningitis and encephalopathy), the dosage may be increased to 3.6 to 4.8 million units of benzathine penicillin G and procaine penicillin G.

The efficacy of Bicillin in treating syphilis has been extensively studied and proven to be safe and effective when administered properly.
