103890-78-4 Usage
Description
Different sources of media describe the Description of 103890-78-4 differently. You can refer to the following data:
1. Lacidipine is a new second-generation dihydropyridine calcium antagonist introduced
as a once a day treatment for mild to moderate hypertension. It is reported to have high
selectivity for vascular smooth muscle and also a long duration of action. The use of
lacidipine as an antiatherosclerotic agent is currently under investigation.
2. Lacidipine is a dihydropyridine L-type calcium channel blocker. It induces relaxation of isolated rat aorta and inhibits calcium-induced contraction of rabbit ear artery (pA2 = 9.4). It also induces relaxation of calcium-induced contractions in isolated rat colon and bladder and guinea pig trachea (IC50s = 6.7, 6, and 7.8 nM, respectively). Lacidipine induces negative inotropy in isolated guinea pig ventricular strips (IC50 = 110 nM). It reduces mean blood pressure in spontaneously hypertensive rats (ED25 = 0.35 mg/kg) and in renal hypertensive dogs (ED25 = 0.22 mg/kg) with a transient increase in heart rate. Lacidipine inhibits copper-induced oxidation of isolated human LDL when used at concentrations of 1 and 5 μM. It reduces the extension of aortic atheromatous lesions and decreases renal injury in ApoE-/- mice in a model of Western diet-induced atherosclerosis.

Biochem/physiol Actions
Lacidipine is a long-acting calcium antagonist that is used in the management of hypertension. Lacidipine is a L-type Ca(2+) channel blocker belonging to 1,4-dihydropyridine class. Also, Lacidipine inhibits ryanodine receptors on the ER membrane that enhances folding, trafficking and lysosomal activity of ERAD (ER-associated degradation) misfolded lysosomal glucocerebrosidase (GS).

Drug interactions
Potentially hazardous interactions with other drugs
Aminophylline and theophylline: possibly increased
aminophylline and theophylline concentration.
Anaesthetics: enhanced hypotensive effect.
Antibacterials: metabolism possibly inhibited by
clarithromycin, erythromycin and telithromycin.
Antidepressants: enhanced hypotensive effect with
MAOIs.
Antiepileptics: effect possibly reduced by
carbamazepine, barbiturates, phenytoin and
primidone.
Antifungals: metabolism possibly inhibited by
itraconazole and ketoconazole; negative inotropic
effect possibly increased with itraconazole.
Antihypertensives: enhanced hypotensive effect,
increased risk of first dose hypotensive effect of postsynaptic alpha-blockers.
Antivirals: concentration possibly increased by
ritonavir.
Ciclosporin: 10 kidney transplant patients on
ciclosporin, prednisone and azathioprine were given
4 mg lacidipine daily. A very small increase in the
trough serum levels (+6%) and AUC (+14%) of the
ciclosporin occurred.
Grapefruit juice: concentration increased - avoid
concomitant use
Metabolism
Lacidipine undergoes extensive first-pass metabolism
in the liver. The drug is eliminated primarily by hepatic
metabolism (involving cytochrome P450 CYP3A4).
The principal metabolites possess little, if any,
pharmacodynamic activity.
Approximately 70% of the administered dose is
eliminated as metabolites in the faeces and the remainder
as metabolites in the urine.
Check Digit Verification of cas no
The CAS Registry Mumber 103890-78-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,8,9 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 103890-78:
(8*1)+(7*0)+(6*3)+(5*8)+(4*9)+(3*0)+(2*7)+(1*8)=124
124 % 10 = 4
So 103890-78-4 is a valid CAS Registry Number.

METHODS FOR TREATING CHRONIC FATIGUE SYNDROME AND MYALGIC ENCEPHALOMYELITIS
-
, (2021/03/13)
In one aspect the invention relates to a method of treatment selected from the group consisting of: (a) treating a symptom such as pain in a subject identified or diagnosed as having Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS); (b) treating a symptom such as pain in a subject having dysfunctional TRPM3 ion channel activity; (c) restoring NK cell function in a subject having dysfunctional TRPM3 ion channel activity; and (d) restoring calcium homeostasis in a subject having dysfunctional TRPM3 ion channel activity. The method comprises the step of administering to the subject a therapeutically effective amount of at least one therapeutic compound selected from the group consisting of: (i) an opioid receptor antagonist; (ii) an opioid antagonist; and (iii) a therapeutic compound that restores TRPM3 ion channel activity. In some embodiments the therapeutic compound is naltrexone hydrochloride.
THERAPY FOR COMPLICATIONS OF DIABETES
-
, (2009/07/02)
A method for enhancing glycemic control and/or insulin sensitivity in a human subject having diabetic nephropathy and/or metabolic syndrome comprises administering to the subject a selective endothelin A (ETA) receptor antagonist in a glycemic control and/or insulin sensitivity enhancing effective amount. A method for treating a complex of comorbidities in an elderly diabetic human subject comprises administering to the subject a selective ETA receptor antagonist in combination or as adjunctive therapy with at least one additional agent that is (i) other than a selective ETA receptor antagonist and (ii) effective in treatment of diabetes and/or at least one of said comorbidities other than hypertension. A therapeutic combination useful in such a method comprises a selective ETA receptor antagonist and at least one antidiabetic, anti-obesity or antidyslipidemic agent other than a selective ETA receptor antagonist.
