Tensigem CD 90 Diltiazem Hydrochloride 90 mg Dosage Form: Oral solid dosage form Medicine Family: Calcium Channel Blocker Cardiovascular Group: Non-dihydropyridine CCB The “CD” Formulation Tensigem CD 90 contains Diltiazem Hydrochloride 90 mg. The CD designation commonly indicates a controlled/extended-release formulation, designed to release diltiazem gradually rather than all at once. Because release systems can vary between brands, the exact formulation and administration instructions should be confirmed from the product pack. Three Cardiovascular Effects Diltiazem affects L-type calcium channels, particularly in cardiac and vascular tissue. 01 | Blood Vessels Reduces calcium-dependent vascular contraction → promotes vasodilation → helps lower vascular resistance. 02 | Heart Rate Can slow activity through the SA and AV nodes, resulting in a lower heart rate in appropriate clinical situations. 03 | Cardiac Workload Reduced vascular resistance and heart-rate effects can decrease myocardial oxygen demand. Clinical Areas Associated With Diltiazem Depending on the formulation and approved labeling, Diltiazem may have roles in: Hypertension — helps control elevated blood pressure. Chronic stable angina — reduces cardiac workload and myocardial oxygen demand. Certain supraventricular arrhythmias — its AV-node effects can be useful for ventricular rate control in selected rhythm disorders. The indication depends significantly on whether the formulation is immediate-release or modified-release. Heart Rate Deserves Attention Unlike many vascular-selective calcium channel blockers, Diltiazem can directly influence cardiac conduction. A particularly slow pulse, new fainting, severe dizziness, or worsening weakness should therefore be medically assessed.
