Is paracetamol safer than acetaminophen?
^ The presence of aniline as an impurity in 19th century batches of acetanilide drugs cannot be ruled out. In this sense as well, paracetamol (acetamino phen) is safer than acetanilide, as (1) the corresponding impurity would be 4-aminophenol, which is less toxic than aniline; and (2) in vivo hydrolysis of the amide group in paracetamol appears to be negligible.
Is acetanilide a drug?
Acetanilide was the first aniline derivative found to possess analgesic as well as antipyretic properties, and was quickly introduced into medical practice under the names of Antifebrin by A. Cahn and P. Hepp in 1886. But its (apparent) unacceptable toxic effects, the most alarming being cyanosis due to methemoglobinemia and ultimately liver and kidney damage, prompted the search for supposedly less toxic aniline derivatives such as phenacetin. After several conflicting results over the ensuing fifty years, it was established in 1948 that acetanilide was mostly metabolized to paracetamol (acetaminophen) in the human body, and that it was this metabolite that was responsible for the analgesic and antipyretic properties. The observed methemoglobinemia after acetanilide administration was ascribed to the small proportion of acetanilide that is hydrolyzed to aniline in the body. Acetanilide is no longer used as a drug in its own right, although the success of its metabolite – paracetamol (acetaminophen) – is well known (although it is itself toxic in excessive amounts ).

When was paracetamol first used?
Paracetamol should have been introduced earlier than 1953, when Sterling & Winthrop marketed it for the first time. Acetanilide and phenacetin were effective in reducing fever and relieving pain, but they had a high incidence of toxic side effects. The former was more toxic, causing cyanosis resulting from methemoglobinemia. It was reported that French chemist Charles Gerhardt synthesized paracetamol in 1852 but did not test it for medical use. Later, in 1878, American chemist Harmon N. Morse also synthesized paracetamol by reducing p-nitrophenol, using tin and glacial acetic acid. Once again, the scientific community did not work to discover the medical uses of the product.
What are the most common compounds in pharmaceutical preparations containing atenolol?

What is ssDNA used for?
ssDNA that was allowed to associate with s-BLMs was used to sensitize s -BLMs for the detection of atenolol. Experiments were performed where injections of various concentrations of atenolol in the bulk electrolyte solution were done after incubation and stabilization of s-BLMs with 6.35 ng/mL dT 20 -C16 in saline solution. Subsequent addition of atenolol standard solution resulted in increases of the ion current when the ssDNA concentration was kept constant. The response time was 18-20 s and the increases of the ion current were linearly related to atenolol concentration [∆I (nA) = 15.9 C (uM) + 100, r 2 = 0.999] for 6.35 ng/mL of dT 20 -C16. The detection limit that was established (for S/N = 3 and for noise levels of 7 nA) was 1.8 uM. The detection limit was 10 fold lower than that observed in the absence of ssDNA. Optimization of the analytical signal was achieved by the use of different oligonucleotide concentrations that were used to treat s-BLMs (e.g. 6.35 and 19.0 ng/mL). Larger concentrations (i.e. more than 19.0 ng/mL) resulted in substantially increased background ion current, and limited the useful analytical range. The results indicated that the ion current values were linearly related to atenolol concentration [∆I (nA) = 15.9 C (uM) + 100, r 2 = 0.999 and ∆I (nA) = 0.958 C (uM) + 17.2, r 2 = 0.990 for 6.35 and 19.0 ng/mL dT 20 -C16, respectively].
What is the pH of PC?
