Isradipine (tradenames DynaCirc, Prescal) is a calcium channel blocker of the dihydropyridine class. It is usually prescribed for the treatment of high blood pressure in order to reduce the risk of stroke and heart attack. Except for diuretic activity, the mechanism of which is not clearly understood, the pharmacodynamics effects of isradipine observed in whole animals can also be explained by calcium channel blocking activity, especially dilating effects in arterioles, which reduce systemic resistance and lower blood pressure, with a small increase in resting heart rate. Isradipine binds to calcium channels with high affinity and specificity and inhibits calcium flux into cardiac and arterial smooth muscle cells. It exhibits greater selectivity towards arterial smooth muscle cells owing to alternative splicing of the alpha-1 subunit of the channel and increased prevalence of inactive channels in smooth muscle cells. Although like other dihydropyridine calcium channel blockers, isradipine has negative inotropic effects in vitro; studies conducted in intact anesthetized animals have shown that the vasodilating effect occurs at doses lower than those do which affect contractility. In patients with normal ventricular function, isradipine's afterload reducing properties lead to some increase in cardiac output. Effects in patients with impaired ventricular function have not been fully studied. Most adverse reactions were mild and related to the vasodilatory effects of isradipine (dizziness, edema, palpitations, flushing, tachycardia), and many were transient. About 5% of isradipine patients left studies prematurely because of adverse reactions (vs. 3% of placebo patients and 6% of active control patients), principally due to headache, edema, dizziness, palpitations, and gastrointestinal disturbances.

Nimodipine is a dihydropyridine calcium antagonist which has been shown to dilate cerebral arterioles and increase cerebral blood flow in animals and humans. It has potential in the treatment of a range of cerebrovascular disorders. Major interest to date, however, has focused on its use in the prevention and treatment of the delayed ischaemic neurological deficits that frequently occur in patients with subarachnoid haemorrhages as a result of sustained cerebral vasospasm. Nimodipine, a Ca2+ antagonist with cerebrovasodilatory and anti-ischemic effects, binds to rat, guinea pig, and human brain membranes with high affinity (less than 1 nM). Only at higher concentrations has nimodipine been reported to block the release of some neurotransmitters and hormones from neuronal tissue.

Ipratropium (ipratropium bromide, ATROVENT® HFA) is a muscarinic antagonist structurally related to atropine but often considered safer and more effective for inhalation use. It is indicated for the maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. Ipratropium (ipratropium bromide, ATROVENT® HFA) is an anticholinergic (parasympatholytic) agent which, based on animal studies, appears to inhibit vagally-mediated reflexes by antagonizing the action of acetylcholine, the transmitter agent released at the neuromuscular junctions in the lung. Anticholinergics prevent the increases in intracellular concentration of Ca2+ which is caused by interaction of acetylcholine with the muscarinic receptors on bronchial smooth muscle.

Piroxicam is in a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). It was originally brought to market by Pfizer under the tradename Feldene in 1980, became generic in 1992, and is marketed worldwide under many brandnames. Piroxicam works by reducing hormones that cause inflammation and pain in the body. Piroxicam is used to reduce the pain, inflammation, and stiffness caused by rheumatoid arthritis and osteoarthritis. The antiinflammatory effect of Piroxicam may result from the reversible inhibition of cyclooxygenase, causing the peripheral inhibition of prostaglandin synthesis. The prostaglandins are produced by an enzyme called Cox-1. Piroxicam blocks the Cox-1 enzyme, resulting into the disruption of production of prostaglandins. Piroxicam also inhibits the migration of leukocytes into sites of inflammation and prevents the formation of thromboxane A2, an aggregating agent, by the platelets. Piroxicam is used for treatment of osteoarthritis and rheumatoid arthritis.

Atenolol is a Beta-1 cardio-selective adreno-receptor blocking agent discovered and developed by ICI in 1976. Atenolol was launched in the market under the trade name Tenormin in 1976, and became the best-selling Beta-blocker in the world in the 1980s and 1990s. TENORMIN is indicated for the treatment of hypertension, to lower blood pressure; also for the long-term management of patients with angina pectoris and also is indicated in the management of hemodynamically stable patients with definite or suspected acute myocardial infarction to reduce cardiovascular mortality. Like metoprolol, atenolol competes with sympathomimetic neurotransmitters such as catecholamines for binding at beta(1)-adrenergic receptors in the heart and vascular smooth muscle, inhibiting sympathetic stimulation. This results in a reduction in resting heart rate, cardiac output, systolic and diastolic blood pressure, and reflex orthostatic hypotension. Higher doses of atenolol also competitively block beta(2)-adrenergic responses in the bronchial and vascular smooth muscles. Hypotensive mechanism of atenolol is very complex. Decrease in CO and inhibition of renin-angiotensin-aldosterone system may mainly be responsible for hypotension. It is likely that potassium retaining action of atenolol partly contributes to its hypotensive action. It is also hypothetized that renal kallikrein-kinin system may play a role in modulating the hypotensive action of atenolol.

Ecraprost [AS 013, Circulase] is a prodrug of prostaglandin E(1) within lipid microspheres that is being developed in Japan by Mitsubishi Pharma Corporation and Asahi Glass. It was originally in development with Welfide Corporation. On 1 October 2001, Welfide Corporation (formerly Yoshitomi) merged with Mitsubishi-Tokyo Pharmaceuticals to form Mitsubishi Pharma Corporation. The new company is a subsidiary of Mitsubishi Chemical. Taisho and Seikagaku Corporation had been involved in the development of ecraprost but discontinued their licences to do so. The effects of ecraprost on reperfusion injury, in preclinical studies, had been reported by Taisho. Ecraprost is in phase II in Japan and was in phase II in Europe for the treatment of peripheral arterial disease. It was also in a phase II study in the treatment of diabetic neuropathies. However, this is no longer an active indication. A phase III trial using a lipid emulsion of ecraprost [Circulase] is underway with Mitsubishi Pharma Corporation in the US, using ecraprost for the treatment of patients with severe peripheral arterial disease, which, because of decreased blood flow to the extremities, can lead to painful ulcers on the legs and feet and subsequent amputation. Alpha Therapeutic Corporation (a former subsidiary of Mitsubishi Pharma) was initially involved in trials of ecraprost in the US, but this responsibility has been taken over by the parent company.

Carboprost is an analogue of naturally occurring prostaglandin F2alpha. Administered intramuscularly carboprost stimulates in the gravid uterus myometrial contractions similar to labor contractions at the end of a full term pregnancy. It is indicated for aborting pregnancy between the 13th and 20th weeks of gestation as calculated from the first day of the last normal menstrual period and for the treatment of postpartum hemorrhage due to uterine atony, which has not responded to conventional methods of management. The most frequent adverse reactions observed are related to its contractile effect on smooth muscle: vomiting, diarrhea, nausea, fever and flushing. Carboprost may augment the activity of other oxytocic agents. Concomitant use with other oxytocic agents is not recommended.

Penicillamine, sold under the trade names of Cuprimine among others, is a medication primarily used for treatment of Wilson's disease, cystinuria and active rheumatoid arthritis. Penicillamine is a chelating agent recommended for the removal of excess copper in patients with Wilson's disease. From in vitro studies which indicate that one atom of copper combines with two molecules of penicillamine. Penicillamine also reduces excess cystine excretion in cystinuria. This is done, at least in part, by disulfide interchange between penicillamine and cystine, resulting in formation of penicillamine-cysteine disulfide, a substance that is much more soluble than cystine and is excreted readily. Penicillamine interferes with the formation of cross-links between tropocollagen molecules and cleaves them when newly formed. The mechanism of action of penicillamine in rheumatoid arthritis is unknown although it appears to suppress disease activity. Unlike cytotoxic immunosuppressants, penicillamine markedly lowers IgM rheumatoid factor but produces no significant depression in absolute levels of serum immunoglobulins. Also unlike cytotoxic immunosuppressants which act on both, penicillamine in vitro depresses T-cell activity but not B-cell activity.
