The nadir of this myelosuppression usually occurs 21–28 days after the first treatment, after which the blood cell and platelet levels in the blood begin to stabilize, often coming close to its pre-carboplatin levels. This decrease in white blood cells (neutropenia) can cause complications, and is sometimes treated with drugs like filgrastim. The most notable complication of neutropenia is increased probability of infection by opportunistic organisms, which necessitates hospital readmission and treatment with antibiotics. Chemistry
In terms of its structure, carboplatin differs from cisplatin in that it has a bidentate dicarboxylate (the ligand is CycloButane DiCarboxylic Acid, CBDCA) in place of the two chloride ligands, which are the leaving groups in cisplatin. For this reason, "CBDCA" is sometimes used in the medical literature as an abbreviation referring to carboplatin. Carboplatin exhibits lower reactivity and slower DNA binding kinetics, although it forms the same reaction products in vitro at equivalent doses with cisplatin. Unlike cisplatin, carboplatin may be susceptible to alternative mechanisms. Some results show that cisplatin and carboplatin cause different morphological changes in MCF-7 cell lines while exerting their cytotoxic behaviour. The diminished reactivity limits protein-carboplatin complexes, which are excreted. The lower excretion rate of carboplatin means that more is retained in the body, and hence its effects are longer lasting (a retention half-life of 30 hours for carboplatin, compared to 1.5-3.6 hours in the case of cisplatin). Mechanism of action
Two theories exist to explain the molecular mechanism of action of carboplatin with DNA:

Aquation, or the like-cisplatin hypothesis.
Several clinical trials have demonstrated the effect of octreotide as acute treatment (abortive agent) in cluster headache, where it has been shown that administration of subcutaneous octreotide is effective when compared with placebo.Octreotide has also been investigated in people with pain from chronic pancreatitis.It has been used in the treatment of malignant bowel obstruction.Octreotide may be used in conjunction with midodrine to partially reverse peripheral vasodilation in the hepatorenal syndrome. By increasing systemic vascular resistance, these drugs reduce shunting and improve renal perfusion, prolonging survival until definitive treatment with liver transplant. Similarly, octreotide can be used to treat refractory chronic hypotension.While successful treatment has been demonstrated in case reports, larger studies have failed to demonstrate efficacy in treating chylothorax.A small study has shown that octreotide may be effective in the treatment of idiopathic intracranial hypertension. Obesity
Octreotide has been used experimentally to treat obesity, particularly obesity caused by lesions in the hunger and satiety centers of the hypothalamus, a region of the brain central to the regulation of food intake and energy expenditure. The circuit begins with an area of the hypothalamus, the arcuate nucleus, that has outputs to the lateral hypothalamus (LH) and ventromedial hypothalamus (VMH), the brains feeding and satiety centers, respectively. The VMH is sometimes injured by ongoing treatment for acute lymphoblastic leukemia (ALL) or surgery or radiation to treat posterior cranial fossa tumors.
