Actions of Caffeine (Koltus P TABLET) in details

sponsored

Caffeine (Koltus P TABLET) stimulates medullary, vagal, vasomotor, and respiratory centers, promoting bradycardia, vasoconstriction, and increased respiratory rate. This action was previously believed to be due primarily to increased intracellular cyclic 3′,5′-adenosine monophosphate (cyclic AMP) following inhibition of phosphodiesterase, the enzyme that degrades cyclic AMP. It is now thought that xanthines such as Caffeine (Koltus P TABLET) act as antagonists at adenosine-receptors within the plasma membrane of virtually every cell. As adenosine acts as an autocoid, inhibiting the release of neurotransmitters from presynaptic sites but augmenting the actions of norepinephrine or angiotensin, antagonism of adenosine receptors promotes neurotransmitter release. This explains the stimulatory effects of Caffeine (Koltus P TABLET). Blockade of the adenosine A1 receptor in the heart leads to the accelerated, pronounced "pounding" of the heart upon Caffeine (Koltus P TABLET) intake.

Mechanism of Action

Caffeine (Koltus P TABLET) is structurally related to other methylxanthines, theophylline, and theobromine. It is a bronchial smooth muscle relaxant, a CNS stimulant, a cardiac muscle stimulant, and a diuretic.

Although the mechanism of action of Caffeine (Koltus P TABLET) in apnea of prematurity is not known, several mechanisms have been hypothesized. These include: (1) stimulation of the respiratory center, (2) increased minute ventilation, (3) decreased threshold to hypercapnia, (4) increased response to hypercapnia, (5) increased skeletal muscle tone, (6) decreased diaphragmatic fatigue, (7) increased metabolic rate, and (8) increased oxygen consumption.

Most of these effects have been attributed to antagonism of adenosine receptors, both A1 and A2 subtypes, by Caffeine (Koltus P TABLET), which has been demonstrated in receptor binding assays and observed at concentrations approximating those achieved therapeutically.

Pharmacokinetics

Absorption

After oral administration of 10 mg Caffeine (Koltus P TABLET) base/kg to preterm neonates, the peak plasma level (Cmax) for Caffeine (Koltus P TABLET) ranged from 6 to 10 mg/L and the mean time to reach peak concentration (Tmax) ranged from 30 minutes to 2 hours. The Tmax was not affected by formula feeding. The absolute bioavailability, however, was not fully examined in preterm neonates.

Distribution

Caffeine (Koltus P TABLET) is rapidly distributed into the brain. Caffeine (Koltus P TABLET) levels in the cerebrospinal fluid of preterm neonates approximate their plasma levels. The mean volume of distribution of Caffeine (Koltus P TABLET) in infants (0.8 to 0.9 L/kg) is slightly higher than that in adults (0.6 L/kg). Plasma protein binding data are not available for neonates or infants. In adults, the mean plasma protein binding in vitro is reported to be approximately 36%.

Metabolism

Hepatic cytochrome P4501A2 (CYP1A2) is involved in Caffeine (Koltus P TABLET) biotransformation. Caffeine (Koltus P TABLET) metabolism in preterm neonates is limited due to their immature hepatic enzyme systems.

Interconversion between Caffeine (Koltus P TABLET) and theophylline has been reported in preterm neonates; Caffeine (Koltus P TABLET) levels are approximately 25% of theophylline levels after theophylline administration and approximately 3 to 8% of Caffeine (Koltus P TABLET) administered would be expected to convert to theophylline.

Elimination

In young infants, the elimination of Caffeine (Koltus P TABLET) is much slower than that in adults due to immature hepatic and/or renal function. Mean half-life (T1/2) and fraction excreted unchanged in urine (Ae) of Caffeine (Koltus P TABLET) in infants have been shown to be inversely related to gestational/postconceptual age. In neonates, the T1/2 is approximately 3 to 4 days and the Ae is approximately 86% (within 6 days). By 9 months of age, the metabolism of Caffeine (Koltus P TABLET) approximates that seen in adults (T1/2 = 5 hours and Ae = 1%).

Special Populations

Studies examining the pharmacokinetics of Caffeine (Koltus P TABLET) in neonates with hepatic or renal insufficiency have not been conducted. Caffeine (Koltus P TABLET) should be administered with caution in preterm neonates with impaired renal or hepatic function. Serum concentrations of Caffeine (Koltus P TABLET) should be monitored and dose administration of Caffeine (Koltus P TABLET) should be adjusted to avoid toxicity in this population.

Clinical Studies

One multicenter, randomized, double-blind trial compared Caffeine (Koltus P TABLET) to placebo in eighty five (85) preterm infants (gestational age 28 to <33 weeks) with apnea of prematurity. Apnea of prematurity was defined as having at least 6 apnea episodes of greater than 20 seconds duration in a 24-hour period with no other identifiable cause of apnea. A 1 mL/kg (20 mg/kg Caffeine (Koltus P TABLET) providing 10 mg/kg as Caffeine (Koltus P TABLET) base) loading dose of Caffeine (Koltus P TABLET) was administered intravenously, followed by a 0.25 mL/kg (5 mg/kg Caffeine (Koltus P TABLET) providing 2.5 mg/kg of Caffeine (Koltus P TABLET) base) daily maintenance dose administered either intravenously or orally (generally through a feeding tube). The duration of treatment in this study was limited to 10 to 12 days. The protocol allowed infants to be “rescued” with open-label Caffeine (Koltus P TABLET) treatment if their apnea remained uncontrolled during the double-blind phase of the trial.

The percentage of patients without apnea on day 2 of treatment (24 to 48 hours after the loading dose) was significantly greater with Caffeine (Koltus P TABLET) than placebo. The following table summarizes the clinically relevant endpoints evaluated in this study:

Chlorpheniramine (Koltus P TABLET) pharmacology

Chlorpheniramine (Koltus P TABLET) acts directly on both alpha- and, to a lesser degree, beta-adrenergic receptors. Through direct action on alpha-adrenergic receptors in the mucosa of the respiratory tract, pseudoephedrine produces vasoconstriction. Chlorpheniramine (Koltus P TABLET) relaxes bronchial smooth muscle by stimulating beta2-adrenergic receptors. Like ephedrine, pseudoephedrine releasing norepinephrine from its storage sites, an indirect effect.

Actions of Paracetamol (Koltus P TABLET) in details

Pharmacology: Paracetamol (Koltus P TABLET) exhibits analgesic and antipyretic activity by inhibiting prostaglandin synthesis. It produces analgesia by elevating the pain threshold and antipyresis through action on the hypothalamic heat-regulating center.

In therapeutic doses, Paracetamol (Koltus P TABLET)'s analgesic and antipyretic action is comparable to that of aspirin. Paracetamol (Koltus P TABLET) does not adversely affect platelet function and hemostasis.

Pharmacokinetics: Paracetamol (Koltus P TABLET) is rapidly and completely absorbed after oral administration. Peak plasma concentrations occur between 15 min to 2 hrs after ingestion. The absolute oral bioavailability of Paracetamol (Koltus P TABLET) is about 80% and is independent of dose in the range of 5-20 mg/kg.

Paracetamol (Koltus P TABLET) is not bound to plasma proteins to any extent. The concentrations of Paracetamol (Koltus P TABLET) in saliva are similar to those in plasma. Concentrations in whole blood are up to 20% higher and in breast milk about 20% lower than the plasma concentration. Paracetamol (Koltus P TABLET) crosses the placenta.

Paracetamol (Koltus P TABLET) is extensively metabolized in the liver and the total body clearance is about 5 mL/kg/min. The clearance of Paracetamol (Koltus P TABLET) is reduced and the half-life increased following a hepatotoxic overdose. Prolongation of half-life beyond 4 hrs usually indicates impending liver damage.

Two to five percent of a therapeutic dose of Paracetamol (Koltus P TABLET) is excreted unchanged in the urine. Its renal clearance is about 10 mL/min and is weakly dependent on urine flow rate but not on pH.

Paracetamol (Koltus P TABLET) administration

May be taken with or without food.

Paracetamol (Koltus P TABLET) pharmacology

The analgesic, antipyretic, and anti-inflammatory effects of aspirin are due to actions by both the acetyl and the salicylate portions of the intact molecule as well as by the active salicylate metabolite. Paracetamol (Koltus P TABLET) directly and irreversibly inhibits the activity of both types of cyclo-oxygenase (COX-1 and COX-2) to decrease the formation of precursors of prostaglandins and thromboxanes from arachidonic acid. This makes aspirin different from other NSAIDS (such as diclofenac and ibuprofen) which are reversible inhibitors. Salicylate may competitively inhibit prostaglandin formation. Paracetamol (Koltus P TABLET)'s antirheumatic (nonsteroidal anti-inflammatory) actions are a result of its analgesic and anti-inflammatory mechanisms; the therapeutic effects are not due to pituitary-adrenal stimulation. The platelet aggregation–inhibiting effect of aspirin specifically involves the compound's ability to act as an acetyl donor to the platelet membrane; the nonacetylated salicylates have no clinically significant effect on platelet aggregation. Paracetamol (Koltus P TABLET) affects platelet function by inhibiting the enzyme prostaglandin cyclooxygenase in platelets, thereby preventing the formation of the aggregating agent thromboxane A2. This action is irreversible; the effects persist for the life of the platelets exposed. Paracetamol (Koltus P TABLET) may also inhibit formation of the platelet aggregation inhibitor prostacyclin (prostaglandin I2) in blood vessels; however, this action is reversible.

Actions of Phenylephrine (Koltus P TABLET) in details

In general, α1-adrenergic receptors mediate contraction and hypertrophic growth of smooth muscle cells. α1-receptors are 7-transmembrane domain receptors coupled to G proteins, Gq/11. Three α1-receptor subtypes, which share approximately 75% homology in their transmembrane domains, have been identified: α1A (chromosome 8), α1B (chromosome 5), and α1D (chromosome 20). Phenylephrine (Koltus P TABLET) appears to act similarly on all three receptor subtypes. All three receptor subtypes appear to be involved in maintaining vascular tone. The α1A-receptor maintains basal vascular tone while the α1B-receptor mediates the vasocontrictory effects of exogenous α1-agonists. Activation of the α1-receptor activates Gq-proteins, which results in intracellular stimulation of phospholipases C, A2, and D. This results in mobilization of Ca2+ from intracellular stores, activation of mitogen-activated kinase and PI3 kinase pathways and subsequent vasoconstriction. Phenylephrine (Koltus P TABLET) produces its local and systemic actions by acting on α1-adrenergic receptors peripheral vascular smooth muscle. Stimulation of the α1-adrenergic receptors results in contraction arteriolar smooth muscle in the periphery. Phenylephrine (Koltus P TABLET) decreases nasal congestion by acting on α1-adrenergic receptors in the arterioles of the nasal mucosa to produce constriction; this leads to decreased edema and increased drainage of the sinus cavities.

How should I take Phenylephrine (Koltus P TABLET)?

IV:

Hypotension/shock: May be administered via continuous infusion (after diluting). When administering as a continuous infusion, central line administration is preferred. IV infusions require an infusion pump.

Hypotension during anesthesia: Administer as an IV bolus over 20 to 30 seconds.

Vesicant; ensure proper needle or catheter placement prior to and during infusion; avoid extravasation.

Extravasation management: If extravasation occurs, stop infusion immediately and disconnect (leave cannula/needle in place); gently aspirate extravasated solution (do NOT flush the line); remove needle/cannula; elevate extremity. Initiate phentolamine (or alternative antidote). Apply dry warm compresses (Hurst 2004; Reynolds 2014).

Phentolamine: Dilute 5 to 10 mg in 10 to 20 mL NS and administer into extravasation site as soon as possible after extravasation; may readminister if patient remains symptomatic (Reynolds 2014).

Alternative to phentolamine: Nitroglycerin topical 2% ointment (based on limited data): Apply a 1-inch strip to the site of ischemia; may repeat every 8 hours as necessary (Reynolds 2014).

Phenylephrine (Koltus P TABLET) pharmacology

Mechanism Of Action

Phenylephrine (Koltus P TABLET) hydrochloride is an a-1 adrenergic receptor agonist.

Pharmacodynamics

Interaction of Phenylephrine (Koltus P TABLET) with a1-adrenergic receptors on vascular smooth muscle cells causes activation of the cells and results in vasoconstriction. Following Phenylephrine (Koltus P TABLET) hydrochloride intravenous administration, increases in systolic and diastolic blood pressures, mean arterial blood pressure, and total peripheral vascular resistance are observed. The onset of blood pressure increase following an intravenous bolus Phenylephrine (Koltus P TABLET) hydrochloride administration is rapid, typically within minutes. As blood pressure increases following intravenous administration, vagal activity also increases, resulting in reflex bradycardia.

Phenylephrine (Koltus P TABLET) has activity on most vascular beds, including renal, pulmonary, and splanchnic arteries.

Pharmacokinetics

Following an intravenous infusion of Phenylephrine (Koltus P TABLET) hydrochloride, the observed effective halflife was approximately 5 minutes. The steady-state volume of distribution of approximately 340 L suggests a high distribution into organs and peripheral tissues. The average total serum clearance is approximately 2100 mL/min. The observed Phenylephrine (Koltus P TABLET) plasma terminal elimination half-life was 2.5 hours.

Phenylephrine (Koltus P TABLET) is metabolized primarily by monoamine oxidase and sulfotransferase. After intravenous administration of radiolabeled Phenylephrine (Koltus P TABLET), approximately 80% of the total dose was eliminated within first 12 h; and approximately 86% of the total dose was recovered in the urine within 48 h. The excreted unchanged parent drug was 16% of the total dose in the urine at 48 h post intravenous administration. There are two major metabolites, with approximately 57 and 8% of the total dose excreted as m-hydroxymandelic acid and sulfate conjugates, respectively. The metabolites are considered not pharmacologically active.

Clinical Studies

The evidence for the efficacy of Phenylephrine (Koltus P TABLET) is derived from studies of Phenylephrine (Koltus P TABLET) hydrochloride in the published literature. The literature support includes 16 studies evaluating the use of intravenous Phenylephrine (Koltus P TABLET) to treat hypotension during anesthesia. The 16 studies include 9 studies where Phenylephrine (Koltus P TABLET) was used in low-risk (ASA 1 and 2) pregnant women undergoing neuraxial anesthesia during Cesarean delivery, 6 studies in non-obstetric surgery under general anesthesia, and 1 study in non-obstetric surgery under combined general and neuraxial anesthesia. Phenylephrine (Koltus P TABLET) has been shown to raise systolic and mean blood pressure when administered either as a bolus dose or by continuous infusion following the development of hypotension during anesthesia.
