Delavirdine is a nonnucleoside reverse transcriptase inhibitor (NNRTI). Delavirdine binds directly to reverse transcriptase (RT) and blocks RNA-dependent and DNA-dependent DNA polymerase activities. Delavirdine does not compete with template:primer or deoxynucleoside triphosphates. HIV-2 RT and human cellular DNA polymerases alfa, gamma, or delta are not inhibited by delavirdine. In addition, HIV-1 group O, a group of highly divergent strains that are uncommon in North America, may not be inhibited by delavirdine. Delavirdine is marketed under the trade name Rescriptor, indicated for the treatment of HIV-1 infection in combination with at least 2 other active antiretroviral agents when therapy is warranted. .

Saquinavir (brand names Invirase and Fortovase) is an antiretroviral drug used together with other medications to treat or prevent HIV/AIDS. Saquinavir is an inhibitor of HIV protease. HIV protease is an enzyme required for the proteolytic cleavage of viral polyprotein precursors into individual functional proteins found in infectious HIV. Saquinavir is a peptide-like substrate analog that binds to the protease active site and inhibits the activity of the enzyme. Saquinavir inhibition prevents cleavage of the viral polyproteins resulting in the formation of immature noninfectious virus particles. The most frequent adverse events with saquinavir in either formulation are mild gastrointestinal symptoms, including diarrhea, nausea, loose stools & abdominal discomfort. Invirase is better tolerated than Fortovase.

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.

Denatonium, usually available as denatonium benzoate (trade names Bitrex) is the most bitter chemical compound known, with bitterness thresholds of 0.05 ppm for the benzoate and 0.01 ppm for the saccharide. Scientists at Macfarlan Smith, Ltd. of Edinburgh, Scotland discovered Bitrex during research on derivatives of the anesthetic lidocaine. The extremely bitter taste proved effective in reducing ingestion by humans and animals. Denatonium is commonly included in placebo medications used in clinical trials to match the bitter taste of certain medications. Denatonium activates bitter taste receptor, mainly, TAS2R4, TAS2R8, TAS2R10, TAS2R13 on many cell types and plays important roles in chemical release, ciliary beating and smooth muscle relaxation through intracellular Ca(2+)-dependent pathways.

PENICILLIN V HYDRABAMINE, a semi-synthetic antibiotic, is used for the treatment of mild to moderately severe infections (e.g. dental infection, infections in the heart, middle ear infections, rheumatic fever, scarlet fever, skin infections, upper and lower respiratory tract infections) caused by susceptible, usually gram-positive, organisms.

PENICILLIN G HYDRABAMINE, a semi-synthetic antibiotic, is used for the treatment of infections caused by susceptible, usually gram-positive, organisms.

ALMECILLIN (also known as penicillin O) is an antibiotic that can be safely substituted for penicillin G in instances of hypersensitivity reactions to the latter.

Theobromine is the primary alkaloid present in the cocoa and chocolate. Theobromine is found in the shells and beans of the cacao plant and it is extracted from the husks of the bean and used for the synthesis of caffeine. Theobromine is an adenosine A1 and A2a receptor antagonist. Thesodate is used as a vasodilator, a diuretic, and heart stimulant. And similar to caffeine, it may be useful in management of fatigue and orthostatic hypotension. The symptomatic adverse reactions produced by theobromine are more or less tolerable and if they become severe, they can be treated symptomatically, these include anxiety, restlessness, tremors, sleeplessness, nausea and vomiting, loss of appetite. Theobromine is currently not in use as a medicinal drug.

Paeonol (2-hydroxy-4-methoxyacetophenone) is a major phenolic component of the dried root bark of Paeonia suffruticosa Andrews (Paeoniaceae). Paeonol exhibits a wide variety of bioactivities including anti-inflammatory, antioxidative, immunoregulatory, antihypertensive, anti-hyperglycemic, antibacterial, anti-thrombotic, and antitumor effects. Paeonol inhibits anaphylactic reaction by regulating histamine and TNF-α. Paeonol tablets have been used for the treatment of rheumatic arthritis, fever, headache and neuralgia in Chinese clinics.
