Yohimbe is the common English name for the tree species P. johimbe (also called Corynanthe johimbe) and, by extension, the name of a medicinal preparation made from the bark of that tree, sold as an aphrodisiac. [6] In contrast, yohimbine is a pure alkaloid that can be isolated from yohimbe bark. Yohimbine is just one of at least 55 indole ...
Pharmacology. Amoxicillin (α-amino- p -hydroxybenzyl penicillin) is a semisynthetic derivative of penicillin with a structure similar to ampicillin but with better absorption when taken by mouth, thus yielding higher concentrations in blood and in urine. [56] Amoxicillin diffuses easily into tissues and body fluids.
However, across the spectrum of dosage of amoxicillin-clavulanate combination, the dose of clavulanate is constant at 125 mg, whereas the dose of amoxicillin varies at 250 mg, 500 mg and 875 mg. Thus the use of low-dose amoxicillin-clavulanate in combination with meropenem may be used in part of a treatment regimen for drug-resistant TB and ...
It is a stereoisomer of yohimbine. [1] Rauwolscine is a central nervous system stimulant, a local anesthetic and a vague aphrodisiac. [1] Rauwolscine acts predominantly as a α 2 -adrenergic receptor antagonist. [2][3] It has also been shown to function as a 5-HT 1A receptor partial agonist and 5-HT 2A and 5-HT 2B receptor antagonist. [4][5][6]
In the 1940s, a vial of 5,000 Oxford units was standard, [24] but the depending on the batch, could contain anything from 15 mg to 20 mg of penicillin. Later, a vial of 1,000,000 international units became standard, and this could contain 2.5 g to 3 g of natural penicillin (a mixture of penicillin I, II, III, and IV and natural impurities).

In toxicology, the median lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 is a toxic unit that measures the lethal dose of a given substance. [1] The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration.
