Oxprenolol is clinically a well-established beta blocker that shares with other members of this group the ability to control a variety of disorders, in particular, hypertension and angina. Pharmacologically it is a nonselective beta blocker that possesses partial agonist activity (intrinsic sympathomimetic activity). Pharmacokinetically, oxprenolol behaves as a moderately lipophilic agent. Oxprenolol undergoes first pass metabolism with only 30% of an oral dose reaching the systemic circulation. The drug is approximately 80% protein bound and is eliminated primarily by glucuronidation in the liver. Less than 4% of oxprenolol is excreted unchanged in the urine. Oxprenolol may reduce the heart rate and prolong the effective and functional atrioventricular nodal refractory period. Oxprenolol has less negative inotropic and chronotropic effects than propranolol. Plasma renin activity is reduced; however, changes in plasma aldosterone level are not significant. Long term metabolic effects require further study. Chest pain (angina), high blood pressure (hypertension), irregular heart beats and anxiety are indications for Oxprenolol usage. To date Oxprenolol is discontinued by FDA.

Meglumine (N-methyl-D-glucamine) is a poorly metabolized derivative of sorbitol that has regulatory acceptance as a benign excipient for drug formulation to increase aqueous solubility of lipophilic drugs and improve their absorption. In conjugated form meglumine is used as a contrast agent.
Lysing is an essential basic amino-acid encoded by codone AAA and AAG, and used in the biosynthesis of proteins. The daily requirement for lysine is 38 mg/kg body weight. The most rich source of lysine is fish, beef, chicken. In a clinical study lysine supplements was found to be an effective for reduction of occurrence, severity and healing time for recurrent HSV infection, however Cochrane Review concluded that the evidence is insufficient. Lysine was investigated for improving anxiety, ameliorating angina prectoris. Lysine acetylsalicylate has been used to treat pain and to detoxify the body after heroin use. Lysine clonixinate has been used for its analgesic properties for the treatment of migraine headaches and other painful conditions. However, limited clinical trials exist for these conditions.

Meprednisone, also known as NSC-63278 and Betapar, is a glucocorticoid receptor agonist.It has anti-inflammatory and immunosuppressive activity. It was approved since 1978, but its marketing in USA was discontinied since. Meprednisone is marketed in Argentina under trade name Copytren for treatment of rheumatic diseases, diseases of collagen, dermatological, gastrointestinal, respiratory and ophtalmological diseases.

Nandrolone, also known as 19-nortestosterone or 19-norandrostenolone, is a semisynthetic anabolic-androgenic steroid derived from testosterone. Nandrolone is used in the form of a variety of long-acting prodrug esters for intramuscular injection, the most common of which are nandrolone decanoate. Nandrolone decanoate is indicated for the management of the anemia of renal insufficiency and has been shown to increase hemoglobin and red cell mass. Certain clinical effects and adverse reactions demonstrate the androgenic properties of this class of drugs. Complete dissociation of anabolic and androgenic effects has not been achieved. The actions of anabolic steroids are therefore similar to those of male sex hormones with the possibility of causing serious disturbances of growth and sexual development if given to young children. Anabolic steroids suppress the gonadotropic functions of the pituitary and may exert a direct effect upon the testis. Anabolic steroids have been reported to increase low-density lipoproteins and decrease high-density lipoproteins. Synthetic version of nandrolone was developed in 1950. But nandrolone for sale appeared later only in 1962 in the form of decanoate under the trade name Deca-Durabolin (Organon company).

LEVAMFETAMINE the levorotatory form of amphetamine. L-amphetamine, is a central nervous system (CNS) stimulant known to increase wakefulness and concentration in association with decreased appetite and fatigue. Pharmaceuticals that contain levoamphetamine are currently indicated and prescribed for the treatment of attention deficit hyperactivity disorder (ADHD), obesity, and narcolepsy in some countries. L-Amphetamine succinate was sold in Hungary between 1952 and 1955 under the brand name Cydril.

Conditions:

Chloramphenicol is a broad-spectrum antibiotic that was first isolated from Streptomyces venezuelae in 1947. The drug was subsequently chemically synthesized. It has both a bacteriostatic and bactericidal effect; in the usual therapeutic concentrations it is bacteriostatic. Chloramphenicol is used for the treatment of serious gram-negative, gram-positive, and anaerobic infections. It is especially useful in the treatment of meningitis, typhoid fever, and cystic fibrosis. It should be reserved for infections for which other drugs are ineffective or contraindicated. Chloramphenicol, a small inhibitor of bacterial protein synthesis, is active against a variety of bacteria and readily enters the CSF. It has been used extensively in the last decades for the treatment of bacterial meningitis. In industrialized countries, chloramphenicol is restricted mostly to topical uses because of the risk of induction of aplastic anemia. However, it remains a valuable reserve antibiotic for patients with allergy to β-lactam antibiotics or with CNS infections caused by multiresistant pathogens.
