Dosage of T Press AM in details
Adults
The usual initial antihypertensive oral dose of T Press AM is 5 mg once daily, and the maximum dose is 10 mg once daily.
Small, fragile, or elderly patients, or patients with hepatic insufficiency may be started on 2.5 mg once daily and this dose may be used when adding T Press AM to other antihypertensive therapy.
Adjust dosage according to blood pressure goals. In general, wait 7 to 14 days between titration steps. Titrate more rapidly, however, if clinically warranted, provided the patient is assessed frequently.
Angina
The recommended dose for chronic stable or vasospastic angina is 5–10 mg, with the lower dose suggested in the elderly and in patients with hepatic insufficiency. Most patients will require 10 mg for adequate effect.
Coronary Artery Disease
The recommended dose range for patients with coronary artery disease is 5–10 mg once daily. In clinical studies, the majority of patients required 10 mg.
Children
The effective antihypertensive oral dose in pediatric patients ages 6–17 years is 2.5 mg to 5 mg once daily. Doses in excess of 5 mg daily have not been studied in pediatric patients.

T Press AM interactions
T Press AM has been safely administered with thiazide diuretics, alpha-blockers, beta-blockers, ACE inhibitors, long-acting nitrates, sublingual nitroglycerine, non-steroidal anti-inflammatory drugs, antibiotics, and oral hypoglycemic drugs.
In vitro data from studies with human plasma indicate that T Press AM has no effect on protein binding of the drugs tested (digoxin, phenytoin, warfarin, or indomethacin).
Simvastatin: Co-administration of multiple doses of 10 mg T Press AM with 80 mg simvastatin resulted in a 77% increase in exposure to simvastatin compared to simvastatin alone. Limit the dose of simvastatin in patients on T Press AM to 20 mg daily.
Grapefruit Juice: Co-administration of 240 mL grapefruit juice with a single oral dose of 10 mg T Press AM in 20 healthy volunteers had no significant effect on the pharmacokinetics of T Press AM. The study did not allow examination of the effect of genetic polymorphism in CYP3A4, the primary enzyme responsible for metabolism of T Press AM; therefore, administration of T Press AM with grapefruit or grapefruit juice is not recommended as bioavailability may be increased in some patients, resulting in increased blood pressure lowering effects.
CYP3A4 Inhibitors: Co-administration of a 180 mg daily dose of diltiazem with 5 mg T Press AM in elderly hypertensive patients (69 to 87 years of age) resulted in a 57% increase in T Press AM systemic exposure. Co-administration of erythromycin in healthy volunteers (18 to 43 years of age) did not significantly change T Press AM systemic exposure (22% increase in area under the concentration versus time curve [AUC]). Although the clinical relevance of these findings is uncertain, pharmacokinetic variations may be more pronounced in the elderly.
Strong inhibitors of CYP3A4 (e.g., ketoconazole, itraconazole, ritonavir) may increase the plasma concentrations of T Press AM to a greater extent than diltiazem. T Press AM should be used with caution when administered with CYP3A4 inhibitors.
Clarithromycin: Clarithromycin is an inhibitor of CYP3A4. There is an increased risk of hypotension in patients receiving clarithromycin with T Press AM. Close observation of patients is recommended when T Press AM is co-administered with clarithromycin.
CYP3A4 Inducers: There is no data available regarding the effect of CYP3A4 inducers on T Press AM. Concomitant use of CYP3A4 inducers (e.g., rifampicin, Hypericum perforatum) may decrease the plasma concentrations of T Press AM. T Press AM should be used with caution when administered with CYP3A4 inducers.
In the following studies, there were no significant changes in the pharmacokinetics of either T Press AM or another drug within the study, when co-administered.
Special Studies: Effect of Other Agents on T Press AM: Cimetidine: Co-administration of T Press AM with cimetidine did not alter the pharmacokinetics of T Press AM.
Aluminum/Magnesium (Antacid): Co-administration of aluminum/magnesium (antacid) with a single dose of T Press AM had no significant effect on the pharmacokinetics of T Press AM.
Sildenafil: A single 100 mg dose of sildenafil in subjects with essential hypertension had no effect on the pharmacokinetic parameters of T Press AM. When T Press AM and sildenafil were used in combination, each agent independently exerted its own blood pressure lowering effect.
Special Studies: Effect of T Press AM on Other Agents: Atorvastatin: Co-administration of multiple 10 mg doses of T Press AM with 80 mg atorvastatin resulted in no significant change in the steady-state pharmacokinetic parameters of atorvastatin.
Digoxin: Co-administration of T Press AM with digoxin did not change serum digoxin levels or digoxin renal clearance in healthy volunteers.
Ethanol (Alcohol): Single and multiple 10 mg doses of T Press AM had no significant effect on the pharmacokinetics of ethanol.
Warfarin: Co-administration of T Press AM with warfarin did not change the warfarin prothrombin response time.
Cyclosporin: Pharmacokinetic studies with cyclosporin have demonstrated that T Press AM does not significantly alter the pharmacokinetics of cyclosporin.
Tacrolimus: There is a risk of increased tacrolimus blood levels when co-administered with T Press AM. In order to avoid toxicity of tacrolimus, administration of T Press AM in a patient treated with tacrolimus requires monitoring of tacrolimus blood levels and dose adjustment of tacrolimus when appropriate.
Drug/Laboratory Test Interactions: None known.
