Cilnidipine (INN) is a calcium channel blocker. It is sold as Atelec in Japan, asCilaheart, Cilacar in India, and under various other trade names in East Asian countries.

Cilnidipine is a dual blocker of L-type voltage-gated calcium channels in vascular smooth muscle and N-type calcium channels in sympathetic nerve terminals that supply blood vessels. However, the clinical benefits of cilnidipine and underlying mechanisms are incompletely understood.

Clinidipine is the novel calcium antagonist accompanied with L-type and N-type calcium channel blocking function. It was jointly developed by Fuji Viscera Pharmaceutical Company, Japan and Ajinomoto, Japan and approved to come into market for the first time and used for high blood pressure treatment in 1995. in india j b chemicals & pharmaceuticals ltd and ncube pharmaceutical develope a market of cilnidipine.

Hypertension is one of the most common cardiovascular disease states, which is defined as a blood pressure greater than or equal to 140/90 mm Hg. Recently, patients with adult disease such as hypertension have rapidly increased. Particularly, since damages due to hypertension may cause acute heart disease or myocardial infarction, etc., there is continued demand for the development of more effective antihypertensive agent.

Meanwhile, antihypertensive agents developed so far can be classified into Angiotensin II Receptor Blocker (ARB), Angiotensin-Converting Enzyme Inhibitor (ACEI) or Calcium Chanel Blocker (CCB) according to the mechanism of actions. Particularly, ARB or CCB drugs manifest more excellent blood pressure lowering effect, and thus they are more frequently used.

However, these drugs have a limit in blood pressure lowering effects, and if each of these drugs is administered in an amount greater than or equal to a specific amount, various side-effects may be caused. Therefore, there have been many attempts in recent years to obtain more excellent blood pressure lowering effect by combination therapy or combined preparation which combines or mixes two or more drugs.

Particularly, since side-effect due to each drug is directly related to the amount or dose of a single drug, there have been active attempts to combine or mix two or more drugs thereby obtaining more excellent blood pressure lowering effect through synergism of the two or more drugs while reducing the amount or dose of each single drug.

For example, US 20040198789 discloses a pharmaceutical composition for lowering blood pressure combining lercanidipine, one of CCB, and valsartan, irbesartan or olmesartan, one of ARB, etc. In addition, a combined preparation composition which combines or mixes various blood pressure lowering drugs or combination therapy thereof has been disclosed.

cilnidipine Compared with other calcium antagonists, clinidipine can act on the N-type calcium-channel that existing sympathetic nerve end besides acting on L-type calcium-channel that similar to most of the calcium antagonists. Due to its N-type calcium-channel blocking properties, it has more advantages compared to conventional calcium-channel blockers. It has lower incidence of Pedal edema, one of the major adverse effects of other calcium channel blockers. Cilnidipine has similar blood pressure lowering efficacy as compared to amlodipine. One of the distinct property of cilnidipine from amlodipine is that it does not cause reflex tachycardia.

In recent years, cardiovascular disease has become common, the incidence increased year by year, about a patient of hypertension in China. 3-1. 500 million, complications caused by hypertension gradually increased, and more and more young patients with hypertension technology. In recent years, antihypertensive drugs also have great development, the main first-line diuretic drug decompression 3 – blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, ar blockers and vascular angiotensin II (Ang II) receptor antagonist.

In the anti-hypertensive drugs, calcium antagonists are following a – blockers after another rapidly developing cardiovascular drugs, has been widely used in clinical hypertension, angina and other diseases, in cardiovascular drugs in the world, ranked first.

Cilnidipine for the long duration of the calcium channel blockers, direct relaxation of vascular smooth muscle, dilation of peripheral arteries, the peripheral resistance decreased, with lower blood pressure, heart rate without causing a reflex effect.

Cilnidipine is a dihydropyridine CCB as well as an antihypertensive. Cilnidipinehas L- and N-calcium channel blocking actions. Though many of the dihydropyridine CCBs may cause an increase in heart rate while being effective for lowering blood pressure, it has been confirmed that cilnidipine does not increase the heart rate and has a stable hypotensive effect.

Olodaterol (trade name Striverdi) is a long acting beta-adrenoceptor agonist used as an inhalation for treating patients with chronic obstructive pulmonary disease (COPD), manufactured by Boehringer-Ingelheim.[1]

see……….https://www.thieme-connect.de/DOI/DOI?10.1055/s-0029-1219649           ……… synfacts

Olodaterol is a potent agonist of the human β2-adrenoceptor with a high β12 selectivity. Its crystalline hydrochloride salt is suitable for inhalation and is currently undergoing clinical trials in man for the treatment of asthma. Oloda­terol has a duration of action that exceeds 24 hours in two preclinical animal models of bronchoprotection and it has a better safety margin compared with formoterol.

Boehringer Ingelheim has launched a new chronic obstructive pulmonary disease drug, Striverdi in the UK and Ireland.
Striverdi (olodaterol) is the second molecule to be licenced for delivery via the company’s Respimat Soft Mist inhaler, following the COPD blockbuster Spiriva (tiotropium). The drug was approved in Europe in November based on results from a Phase III programme that included more than 3,000 patients with moderate to very severe disease.http://www.pharmatimes.com/Article/14-07-01/BI_launches_COPD_drug_Striverdi_in_UK_and_Ireland.aspx

Olodaterol hydrochloride is a drug candidate originated by Boehringer Ingelheim. The product, delivered once-daily by the Respimat Soft Mist Inhaler, was first launched in Denmark and the Netherlands in March 2014 for the use as maintenance treatment of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema. In 2013, approval was obtained in Russia and Canada for the same indication, and in the U.S, the product was recommended for approval. Phase III clinical trials for the treatment of COPD are ongoing in Japan.

Medical uses

Olodaterol is a once-daily maintenance bronchodilator treatment of airflow obstruction in patients with COPD including chronic bronchitis and/or emphysema, and is administered in an inhaler called Respimat Soft Mist Inhaler.[2][3][4][5][6][7]

As of December 2013, olodaterol is not approved for the treatment of asthma. Olodaterol monotherapy was previously evaluated in four Phase 2 studies in asthma patients. However, currently there are no Phase 3 studies planned for olodaterol monotherapy in patients with asthma.

In late January 2013, Olodaterol CAS# 868049-49-4 was the focus of an FDA committee reviewing data for the drug’s approval as a once-daily maintenance bronchodilator to treat chronic obstructive pulmonary disease (COPD), as well as chronic bronchitis and emphysema. The FDA Pulmonary-Allergy Drugs Advisory Committee recommended that the clinical data from the Boehringer Ingelheim Phase III studies be included in their NDA.

Also known as the trade name Striverdi Respimat, Olodaterol is efficacious as a long-acting beta-agonist, which patients self-administer via an easy to use metered dose inhaler. While early statistics from clinical trials of Olodaterol were encouraging, a new set of data was released earlier this week, which only further solidified the effectual and tolerable benefits of this COPD drug.

On September 10, 2013 results from two Phase 3 studies of Olodaterol revealed additional positive results from this formidable COPD treatment. The conclusion from these two 48 week studies, which included over 3,000 patients, showed sizable and significant improvements in the lung function of patients who were dosed with Olodaterol. Patients in the aforementioned studies were administered either a once a day dosage of Olodaterol via the appropriate metered-dose inhaler or “usual care”. The “usual care” included a variety of treatment options, such as inhaled corticosteroids (not Olodaterol), short and long acting anticholinergics, xanthines and beta agonists, which were short acting. The clinical trial participants who were dosed with Olodaterol displayed a rapid onset of action from this drug, oftentimes within the first five minutes after taking this medication. Additionally, patients dispensed the Olodaterol inhaler were successfully able to maintain optimum lung function for longer than a full 24 hour period. The participants who were given Olodaterol experienced such an obvious clinical improvement in their COPD symptoms, and it quickly became apparent that the “usual care” protocol was lacking in efficacy and reliability.

A staggering 24 million patients in the United States suffer from chronic obstructive pulmonary disease, and this patient population is in need of an effectual, safe and tolerable solution. Olodaterol is shaping up to be that much needed solution. Not only have the results from studies of Olodaterol been encouraging, the studies themselves have actually been forward thinking and wellness centered. Boehringer Ingelheim is the first company to included studies to evaluate exercise tolerance in  patients with COPD, and compare the data to those patients who were dosed with Olodaterol. By including exercise tolerance as an important benchmark in pertinent data for Olodaterol, Boehringer Ingelheim has created a standard for COPD treatment expectations. The impaired lung function for patients with COPD contributes greatly to their inability to exercise and stay healthy. Patients who find treatments and management techniques to combat the lung hyperinflation that develops during exercise have a distinct advantage to attaining overall good health.

Data has demonstrated that Striverdi, a once-daily long-acting beta2 agonist, significantly improved lung function versus placebo and is comparable to improvements shown with the older LABA formoterol. The NHS price for the drug is £26.35 for a 30-day supply.

Boehringer cited Richard Russell at Wexham Park Hospital as saying that the licensing of Stirverdi will be welcomed by clinicians as it provides another option. He added that the trial results showing improvements in lung function “are particularly impressive considering the study design, which allowed participants to continue their usual treatment regimen. This reflects more closely the real-world patient population”.

Significantly, the company is also developing olodaterol in combination with Spiriva, a long-acting muscarinic antagonist. LAMA/LABA combinations provide the convenience of delivering the two major bronchodilator classes.

Olodaterol is a novel, long-acting beta2-adrenergic agonist (LABA) that exerts its pharmacological effect by binding and activating beta2-adrenergic receptors located primarily in the lungs. Beta2-adrenergic receptors are membrane-bound receptors that are normally activated by endogenous epinephrine whose signalling, via a downstream L-type calcium channel interaction, mediates smooth muscle relaxation and bronchodilation. Activation of the receptor stimulates an associated G protein which then activates adenylate cyclase, catalyzing the formation of cyclic adenosine monophosphate (cAMP) and protein kinase A (PKA). Elevation of these two molecules induces bronchodilation by relaxation of airway smooth muscles. It is by this mechanism that olodaterol is used for the treatment of chronic obstructive pulmonary disease (COPD) and the progressive airflow obstruction that is characteristic of it. Treatment with bronchodilators helps to mitigate associated symptoms such as shortness of breath, cough, and sputum production. Single doses of olodaterol have been shown to improve forced expiratory volume in 1 sec (FEV1) for 24 h in patients with COPD, allowing once daily dosing. A once-a-day treatment with a LABA has several advantages over short-acting bronchodilators and twice-daily LABAs including improved convenience and compliance and improved airflow over a 24-hour period. Despite similarities in symptoms, olodaterol is not indicated for the treatment of acute exacerbations of COPD or for the treatment of asthma.

Adverse effects

Adverse effects generally were rare and mild in clinical studies. Most common, but still affecting no more than 1% of patients, were nasopharyngitis (running nose), dizziness and rash. To judge from the drug’s mechanism of action and from experiences with related drugs, hypertension (high blood pressure), tachycardia (fast heartbeat), hypokalaemia (low blood levels of potassium), shaking, etc., might occur in some patients, but these effects have rarely, if at all, been observed in studies.[1]

Interactions

Based on theoretical considerations, co-application of other beta-adrenoceptor agonists, potassium lowering drugs (e. g. corticoids, many diuretics, and theophylline), tricyclic antidepressants, and monoamine oxidase inhibitors could increase the likelihood of adverse effects to occur. Beta blockers, a group of drugs for the treatment of hypertension (high blood pressure) and various conditions of the heart, could reduce the efficacy of olodaterol.[1] Clinical data on the relevance of such interactions are very limited.

Pharmacology

Mechanism of action

Like all beta-adrenoceptor agonists, olodaterol mimics the effect of epinephrine at beta-2 receptors (β₂-receptors) in the lung, which causes the bronchi to relax and reduces their resistance to airflow.[3]

Olodaterol is a nearly full β₂-agonist, having 88% intrinsic activity compared to the gold standard isoprenaline. Its half maximal effective concentration (EC50) is 0.1 nM. It has a higher in vitro selectivity for β₂-receptors than the related drugs formoterol and salmeterol: 241-fold versus β₁- and 2299-fold versus β₃-receptors.[2] The high β₂/β₁ selectivity may account for the apparent lack of tachycardia in clinical trials, which is mediated by β₁-receptors on the heart.

Pharmacokinetics

Once bound to a β₂-receptor, an olodaterol molecule stays there for hours – its dissociation half-life is 17.8 hours –, which allows for once-a-day application of the drug[3] like with indacaterol. Other related compounds generally have a shorter duration of action and have to be applied twice daily (e.g. formoterol, salmeterol). Still others (e. g. salbutamol, fenoterol) have to be applied three or four times a day for continuous action, which can also be an advantage for patients who need to apply β₂-agonists only occasionally, for example in an asthma attack.[8]

 

History

On 29 January 2013 the U.S. Food and Drug Administration (FDA) Pulmonary-Allergy Drugs Advisory Committee (PADAC) recommended that the clinical data included in the new drug application (NDA) for olodaterol provide substantial evidence of safety and efficacy to support the approval of olodaterol as a once-daily maintenance bronchodilator treatment for airflow obstruction in patients with COPD.[9]

On 18 October 2013 approval of olodaterol in the first three European countries – the United Kingdom, Denmark and Iceland – was announced by the manufacturer.[10]

Synthesis of olodaterol hydrochloride (XVI).

Image result for OLODATEROL DRUG FUTURE

Olodaterol hydrochloride was approved for long-term, once-daily maintenance treatment of chronic
obstructive pulmonary disease (COPD) in 2013 in the following countries: Canada, Russia, United
Kingdom, Denmark, and Iceland.142, 143 The drug has been recommended by a federal advisory panel for
approval by the FDA.142, 143 Developed and marketed by Boehringer Ingelheim, olodaterol is a longacting
β2-adrenergic receptor agonist with high selectivity over the β1- and β3-receptors (219- and 1622-fold, respectively).144 Upon binding to and activating the β2-adrenergic receptor in the airway, olodaterol
stimulates adenyl cyclase to synthesize cAMP, leading to the relaxation of smooth muscle cells in the
airway. Administered by inhalation using the Respimat®
Soft Mist inhaler, it delivers significant
bronchodilator effects within five minutes of the first dose and provides sustained improvement in
forced expiratory volume (FEV1) for over 24 hours.143 While several routes have been reported in the
patent and published literature,144-146 the manufacturing route for olodaterol hydrochloride disclosed in
2011 is summarized in Scheme 19 below.147
Commercial 2’,5’-dihydroxyacetophenone (122) was treated with one equivalent of benzyl bromide
and potassium carbonate in methylisobutylketone (MIBK) to give the 5’-monobenzylated product in
76% yield. Subsequent nitration occurred at the 4’-position to provide nitrophenol 123 in 87% yield.
Reduction of the nitro group followed by subjection to chloroacetyl chloride resulted in the construction
of benzoxazine 124 in 82% yield. Next, monobromination through the use of tetrabutylammonium
tribromide occurred at the acetophenone carbon to provide bromoketone 125, and this was followed by
asymmetric reduction of the ketone employing (−)-DIP chloride to afford an intermediate bromohydrin,
which underwent conversion to the corresponding epoxide 126 in situ upon treatment with aqueous
NaOH. This epoxide was efficiently formed in 85% yield and 98.3% enantiomeric excess. Epoxide
126 underwent ring-opening upon subjection to amine 127 to provide amino-alcohol 128 in in 84-90%
yield and 89.5-99.5% enantiomeric purity following salt formation with HCl. Tertiary amine 127 was
itself prepared in three steps by reaction of ketone 129 with methylmagnesium chloride, Ritter reaction
of the tertiary alcohol with acetonitrile, and hydrolysis of the resultant acetamide with ethanolic
potassium hydroxide. Hydrogenative removal of the benzyl ether within 128 followed by
recrystallization with methanolic isopropanol furnished olodaterol hydrochloride (XVI) in 63-70%
yield. Overall, the synthesis of olodaterol hydrochloride required 10 total steps (7 linear) from
commercially available acetophenone 122.

The active moiety olodaterol is a selective beta2-adrenergic bronchodilator. The drug substance, olodaterol hydrochloride, is chemically described as 2H-1,4- Benzoxazin-3H(4H)-one, 6-hydroxy-8-[(1R)-1-hydroxy-2-[[2-(4-methoxyphenyl)-1,1-dimethylethyl]-amino]ethyl]-, monohydrochloride. Olodaterol hydrochloride is a white to off-white powder that is sparingly-slightly soluble in water and slightly soluble in ethanol. The molecular weight is 422.9 g/mole (salt): 386.5 g/mole (base), and the molecular formula is C21H26N2O5 x HCl as a hydrochloride. The conversion factor from salt to free base is 1.094.

The structural formula is:

STRIVERDI® RESPIMAT® (olodaterol) Structural Formula Illustration

The drug product, STRIVERDI RESPIMAT, is composed of a sterile, aqueous solution of olodaterol hydrochloride filled into a 4.5 mL plastic container crimped into an aluminum cylinder (STRIVERDI RESPIMAT cartridge) for use with the STRIVERDI RESPIMAT inhaler.

Excipients include water for injection, benzalkonium chloride, edetate disodium, and anhydrous citric acid. The STRIVERDI RESPIMAT cartridge is only intended for use with the STRIVERDI RESPIMAT inhaler. The STRIVERDI RESPIMAT inhaler is a hand held, pocket sized oral inhalation device that uses mechanical energy to generate a slow-moving aerosol cloud of medication from a metered volume of the drug solution. The STRIVERDI RESPIMAT inhaler has a yellow-colored cap.

When used with the STRIVERDI RESPIMAT inhaler, each cartridge containing a minimum of 4 grams of a sterile aqueous solution delivers the labeled number of metered actuations after preparation for use. Each dose (1 dose equals 2 actuations) from the STRIVERDI RESPIMAT inhaler delivers 5 mcg olodaterol in 22.1 mcL of solution from the mouthpiece. As with all inhaled drugs, the actual amount of drug delivered to the lung may depend on patient factors, such as the coordination between the actuation of the inhaler and inspiration through the delivery system. The duration of inspiration should be at least as long as the spray duration (1.5 seconds).
